Chemicals

Chemicals are one of the main culprits that cause skin cancer especially environmental chemicals like petroleum products and coal tar pitch. These chemicals cause photo-sensitisation, which means skin becomes more sensitive towards UV-lights.

Plants that have chemicals like psoralens also have potential to increase photo-sensitivity. When these chemicals have contact with skins there are lots of chances for skin cancer.

Cigarettes

Smoking plays great role in skin cancer. Researches have said that smokers diagnosed with sguamous cell carcinoma 3.3 times then non-smokers. Studies have proved that the toxic chemicals and the reduced oxygen in the blood stream caused by smoking directly damage the skin.

Apart from that smoking have the potential to inhabit the immune system that leave the body weaker and that in turn leads to cancer straight away. People believe smoking is one of the major factors in what causes skin cancer.

Skin cancer Heredity

People who have light eyes and fair skins from their parents can easily catches the sunburn. Even the minimal exposure of sun rays have the potential to bring the risk of diagnosed with melanoma.

Young child and infants have more risks rather than adults. Even a single sun burn sometimes brings sever blisters. It is advisable to keep the babies out of sun at least for six months and you can use board spectrum sunscreen on babies to protect them.

Effects of sunscreen

Sunscreen products plays great role in preventing skin cancer. Unfortunately, most people fail to use enough sunscreen or use them insufficiently, which do not fulfill the actual purpose. In spite of this not every sunscreen protects all the harmful rays of sun.

People should aware of sunscreen products and they must use that whenever needed. Remember failure to use or limit exposure always increase the risks of skin cancer.

However, there are some sunscreens contains chemicals that are carcinogenic, which have the potential to affect hormones in women. So, make sure to buy the quality sunscreen products to avoid skin cancer.

Dental check-up

When we speak about what causes skin cancer, regular dental check-up also plays great role in preventing skin cancer because dentist not only look into your teeth but he also look the conditions of erythropakia (red sore area) and leukoplakia (white patches) while checking-up your teeth.

Though these two factors are not into cancer but both have the potential to cause oral cancer, which is part of skin cancer.

Moles & Hair

We all believe that removing hair in a mole is safe thing but in fact this process of removal of hair has the potential to cause sore if you are not well-trained in hair removing in moles. So, be trained before begin this process. Remember to consider irritation, itching and bleeding and consult with doctor if it happens after the removal of hair in the mole.

There are higher chances of white skinned men suffering from testicular cancer as compared to men of other races and the most common age group happens to be 15 to 40. It has also been noticed that men suffering from cryptorchidism – a problem where the testicles are undescended, stand a higher risk of developing testicular cancer, even if surgery has been performed to set right the problem. Also genetic factors and abnormal development of the testicles can lead to the same.

Even though testicular cancer is completely curable if detected in the earliest stages, most men suffering from it realize the problem only after the cancer has spread beyond the testicles to other surrounding parts. In most cases, the man himself figures out that he is suffering from testicular cancer. Doctors always suggest that a man suspecting testicular cancer should have the state of their testicles tested at least once every month. This test is called the TSE or the testicular self-examination. The frequent need to test your testicles will always help to detect testicular cancer in its earliest stages and thus help in early recovery – especially in the case of those who have genetic threats of incurring the same. The test is easy and you are only required to feel your testicles from the top to the bottom to try and sense any form of lumps that you might feel needs medical intervention and if the need be, medial assistance is never too far away.

Other than the development of lumps in the testicles, other warning signs of testicular cancer is swelling of the testicles, pain around the testicular region, pain in the lower abdomen and groin area, enlargement of the testicles, and accumulation of fluid in the scrotum or swelling of the scrotum.

In most cases, it is seen that men do not even realize they have testicular cancer till the cancer has spread to its last stage and then obviously the malignancy is beyond all cure. Because the symptoms of testicular cancer are not easy to notice, men often report having no problems. However please do keep in mind that if you do experience the symptoms and signs listed before, it does not necessarily mean that you have testicular cancer. On noticing the signs above, you must consult a doctor so you can be guided and recommended treatment if necessary for cancer of for whatever it is that you have been suffering from.

• Malignant Melanoma: This category of skin cancer gives diagnoses lesser than 10%. It mainly develops in the melanocytes cells, which produce melanin. It begins when there is some problem in the process of cell division and the melanocytes begin to divide and multiply enormously. This leads to the development of a tumor on the skin. The appearance of tumor is like a big mole of brown color and it can occur on arms, back, legs or face of a human being. Its shape resembles to a mole, but color gives the variation for the case of a tumor. They are also larger and more uneven in shape and size. This is the dangerous in all types of skin cancer and if not treated quickly, can cause deadlier skin cancer problems.
• Basal Cell Carcinoma (BCC): It is the most common type of skin cancer and has an account for about 75%R of all diagnosis. The main reason for this problem is the uneven basal cells in epidermis and the formation of a cancerous tumor on the outer surface of skin. It appears like a red ulcer on skin, which can get itching, bleeding or crust. This cancer appears on the body, which is mostly exposed to sun and specifically occurs on the region of face, arms or legs. It is the most common kind of skin problem and rarely kills humans. If not treated on time, it can leave the skin to look disfigured.
• Squamous Cell Carcinoma: This skin cancer type has a 15-20% probability between skin cancers. The main cause of this disease is that the squamous cells of the outer layer of skin begin to grow in an uncontrollable way, which leads to the formation of a cancer tumor. It resembles a hard red lump or creates scales or scabs on the skin. Similar to BCC, these cells appear on the body parts exposed to sun. It is not a deadly disease. It can spread to other body areas, if not treated immediately.

It is always preferable to know about all types of skin cancer, so that you can know about them and help yourself and the people around you. If you notice anything suspicious on your skin and its condition worsens in some time duration, then there is nothing to wait for it. The key for treatment for all types of skin cancer is to detect it soon and get tested from dermatologist. You should seek for an immediate medical help for any issues relating to cancer.

Cancer has been a cause of trauma for most of the individuals in this world. So if a question is asked as to how many people in this world has cancer then it would not be wise to follow the answer that might pop out. One tenth of the entire World almost suffers from cancer. There would be many controversies regarding approximate figures or percentages relating to that. A number of preventive vaccines have been invented but a proper and definite cure has not yet been established. In the initial stages of a diagnosis which shows indications of a cancer may be treated with radiation therapy, chemotherapy, antibody therapies or by prophylactic vaccines. But it still keeps many of us at the wit’s end if we sit down and wonder how many people in the world have cancer?

The World Health Organization has predicted a 50% rise in the levels of cancer by 2020. It doesn’t speak all that good either that some countries witness around a quarter of deaths annually through cancer. The WHO has also stated that the most prominent cause of cancer has been tobacco. The lifestyle and trends of humans across the world has also been a major reason for this deadly disease to take away a lot of lives. So if you are looking for an answer to your question of really how many people in the world have cancer then it’s really a cause of worry and concern.

The mostly prevailing cases of cancer have been oral cancer, pharynx, larynx, stomach and lung and breast cancer. So it’s clear that the largest section of the cancer is caused by tobacco which people consume in spite of the statutory warnings and global awareness.

The Western lifestyle has higher risk of cancer rates owing to the high calorific diet items, fatty diet supplements, and animal proteins and overall lower physical activities have opened the doors for energy imbalance and the cause of cancer being one of the most prevalent diseases.

Obesity has also been one major factor in getting diagnosed with cancer and the developed countries have more rates of obese people. So the developed countries are facing almost 50% cancer diagnosis while the developing countries face about 80% late incurable cancer stages. So all throughout the world this disease prevails and is even expected to grow in rapid rates. So how many people in the world have cancer? Any answer or even trying to find that answer approximately pushes the humans into cutting sorry figures.

1. Tobacco
The National Cancer Institute states that 30% of the total deaths in the US caused by cancer are due to excessive smoking and for those who do not die, but suffer from cancer throughout their lives – 87% of such cases are affected solely by smoking. Tobacco damages not only your lungs, but can also affect the kidneys, the pancreas, the cervix and many a cases leads to myeloid leukemia. The moment you stop smoking, you are reducing your chances of cancer drastically.

2. Lack of Physical Exercise
Exercising your body for only half an hour everyday and 5 times a week can help to prevent cancer. Lethargy leads to obesity and that is one of the predominant causes of cancer and exercising, practicing yoga, indulging in aerobics or simply walking and jogging can help to reduce you chances of developing cancer. Obesity problems lead to development of cancer in the breasts, colon, prostate and lungs.

3. Genetics
Genetic factors are yet another cause of cancer development. If there are members in your family who have suffered cancer in different organs of the body, you stand very high chances of developing the same. Genetic cancer causes a mutated gene to pass on to the offspring. However if you have family members who have experienced cancer, it does not mean you will indefinitely develop the same but your chances are high.

4. Environmental factors
Exposure to asbestos is known to cause cancer in many people. Asbestos sedimentation in your system will give rise to mesothelioma that might eventually grow in to becoming cancer. Similarly exposure to benzene causes cancer in people too.

5. Unsafe Sex
Indulging in unprotected sex time and over again gives rise to a virus called HPV, which is a collection of over 90 viruses. HPV might lead to causing anal, cervical, vulvar and vaginal cancer. There are laboratory tests to tell you if you have contracted the HPV virus so you can always check before rushing to a doctor for assistance.

6. Exposure to Sun
Ultraviolet rays of the sun cause skin cancer. Sunburn or tans, which you must always be very negligible of, is actually the result of cell damage. Wearing a sunscreen with a very high SPF value can help to avoid this risk. Try to avoid staying outdoors at times when the rays of the sun are hottest and hitting you directly. Being slightly more careful could help you to avoid fatal diseases such as cancer. After all, prevention is better than cure.

The three types of skin cancers are named according to the type of skin cells on which they originate. Skin cancer is less deadly than lung, colon or stomach cancer. It is the most common type of cancer. Though melanoma is rarely found in comparison to the other types like basal cell cancer yet it poses a grave danger. Melanoma is usually found in the younger generation. The action of sun rays on the skin is primarily the main reason for skin cancer. Generally these are local infections and caused due to constant exposure to sun. This does not spread to adjacent areas. The signs of skin cancer are plenty in number starting from discoloration of skin, ulcer conditions and visible changes in the skin that refuse to heal. Discoloration of mole or its enlargement can also be considered as one of the signs of skin cancer.

In case of basal cell carcinoma, a raised structure of pear shape having a smooth outline is seen on areas like the head, shoulders or the neck. One can also see blood vessels emanating across the tumor. A crust develops and bleeding takes place eventually. Sometimes it may so happen that one mistakenly takes the signs of skin cancer for a sore that does not heal with time.

Now, squamous cell carcinoma is characterized by scales on the skin which are thickened at the edges and are red in color. This type of skin cancer is mainly seen in places where the sun acts the most. Melanoma is the most dangerous type of skin cancer among the three.

Melanomas are lesions which are of black or brown color. Any change in the size, color or bulge of the mole can be taken as symptoms of skin cancer of melanoma type. Ulceration and bleeding are often visible in such cases. Then there are raised spots of purple or red skin which are non-itchy but they grow really very fast. Merkel cell carcinomas are of this variety.

As soon as one is able to interpret the signs of skin cancer, he should consult the doctor immediately to get the right treatment at the right moment. Otherwise, it may take a malignant form. A dermatoscope clearly reveals the condition of the area of an afflicted person during clinical diagnosis. Melanoma can be easily identified with the aid of the ABCD guideline. A skin biopsy is the essential requirement for the clinical diagnostic treatment. Shave and punch biopsies are among the many techniques used for this purpose.

People are unaware of the importance of the clinical trials for cancer or for that matter any other disease. The clinical trials help establish the effectiveness of a treatment, besides testing it for any major side effects before it can be used for mass treatment. The trials are allowed to be performed only after acceptable and adequate data has been obtained about the quality and safety of the treatment to be administered through a new drug, surgery, or device. The approval to use the new method of treatment is guaranteed only after the results of the trial are accessed by the responsible authority.

The methods of conducting clinical trials for cancer are quite different from the ones used for other diseases. This is because, even though all types of cancers result in causing tumors, the response of each type is different for each drug. Hence, when a clinical trial is conducted for cancer, it is aimed at testing the response of a particular type of cancer for the new method of treatment. The clinical trial is carried out on volunteer cancer patients who hope to gain some sort of benefit during the course of the experimental treatment. The clinical trials are generally carried out in three different phases which are explained in the following paragraphs.

In the first phase of clinical trial for cancer or any other disease, the new method of treatment is administered to a very small group of patients. This helps researchers in accessing as to how safe and affective the treatment is actually on humans, in addition to analyzing any type of side affects caused by the treatment. Mostly, 70%of treatments undergoing trials pass this phase to go on to Phase 2.
In Phase 2 of the clinical trial, the effectiveness of the treatment for the specific ailment is tested. This means that if the clinical trial for cancer is aimed at testing the treatment of breast cancer, the analysis of the results in Phase 2 will be focused on how affective the treatment has proved for breast cancer patients. This phase is cleared by only about 1/3 of the treatments undergoing clinical trials.
The phase 3 of clinical trial for cancer or any other disease, I lasts the longest and involves the maximum number of patients. This phase is aimed to further establish the safety, side effects and effectiveness of the new method of treatment. Once the treatment has successfully passed all the three phases, it can be used for mass treatment of the disease after being approved by the regulatory bodies.

Persistent fatigue is one of the symptoms of cancer. It is experienced more commonly when the cancer has already spread to a number of organs in the body. If it can be noticed in the initial stages nothing better as treatment can begin immediately. This fatigue is usually the product of anemia. Fatigue is felt even if the cancer is non-malignant so check with a physician at the earliest.

Sudden weight loss is mostly welcome but it might also be an alert for some of the most damaging health problems – including cancer. If you lose more than 10 pounds without having tried to in a short period of time, you must visit a doctor. This weight loss stems mostly from loss of appetite. While losing weight is a symptom of cancer, you may lose weight if you don’t have cancer but a lesser damaging problem.

While pain might be experienced due to many reasons, on many occasions, cancer causes the pain to reach the bones of the body. Pain in the lower back could be a symptom of ovarian cancer or colon cancer, pain in the shoulder could be a symptom of lung cancer while pain in the head could be a symptom of brain cancer. Though fever is a non-specific symptom, persistent temperature with cough and hoarsening of voice can be a minor symptom of cancer.

Lastly, bowel changes such as constipation, bloody stool, diarrhea, gas, and loose motions could also be symptoms of cancer. Of course these are simpler problems, which you might experience anyway, but a check with a doctor wouldn’t do you harm. Also blood in the sputum or a brownish tinged spit can mean you have lung cancer.

While these are general and very non specific symptoms of cancer, a very assertive experience of one or more of these means that you should visit a doctor at the earliest. Even if not cancer, the symptoms do not show that your body is at its best state and needs the supervision of a doctor. Also most cancer patients experience these symptoms at different stages of their cancer. So do not neglect your condition and head to a doctor straight away. You might be required to take tests to either state that the symptoms are malignant or they are non-malignant. Whichever the case might be, you would be in need of some medication. So do not waste time.

The best way to become aware of the signs of breast cancer is to do regular self examination. This specifically includes checking the breasts for any abnormal changes and lumps etc. Although one cannot be sure of whether one is having breast cancer only through physical examination, it can be the first step in either confirming the onset of the disease or eliminating any doubts about its presence. Early detection of breast cancer can even help prevent the patients from undergoing the trauma of mastectomy.

The earliest signs of breast cancer appear in the form of lumps in the breasts. Not all lumps are cancerous and sometimes can even be caused by a cyst inside the breast. Such lumps are not dangerous and do not in any way affect a person’s chance of getting breast cancer. However, whether a lump is cancerous or is just a cyst can only be determined by a well experienced medical practitioner. So in case a person finds any lumps that are different from the other areas of the breast, it is always advisable to get a proper check up done.

The other signs of breast cancer are an immediate change in the size and shape of the breasts. This can be caused by the growth of cancer cells inside the breasts. Some people might also notice some markings or dimpling on the breast and might also feel some inversion in the nipples. In addition, there might be a clear or even a bloody discharge occurring from the nipples as well as unusual pain in the breasts and under arm areas. In case of any or all of these symptoms, a person should immediately contact their doctor for a proper check up.

Other signs of breast cancer can be the Paget’s disease, whose symptoms are similar to eczema and hence are easily taken for granted. However, if a person feels redness, itching and burning and even some tingling feeling in the breast, it should not be ignored just as regular eczema and the advice of a good doctor should be taken. Moreover, one should also take into consideration the other symptoms of cancer which include unexplained weight loss, swollen lymph nodes and even joint pains.

It is vital to understand that these symptoms might turn out to be either the signs of breast cancer or even some other disease. The important thing is to understand these symptoms and do the required follow up to determine the causes behind them for their proper treatment and eradication.

Colon cancer causes an abnormal growth of cells in the colon which in turn results in the creation of a cancerous tumor. The disease is generally found to affect people above the age of 50 years but in some rare cases has also been diagnosed in much younger people. Failure to detect the colon cancer early symptoms might cause the cancer to engulf not only the entire colon and the rectum, but to spread to other vital body organs as well. So it is vital that any symptoms, no matter how insignificant they might seem, should not be ignored and should be discussed in detail with a well experienced medical practitioner.

Some of the most common colon cancer early symptoms include pain in the abdomen, discomfort or even swelling. A person might pass blood with stool and might even have long and thin stool. There might be unintentional weight loss in addition to which a person might not feel like eating anything. Some people might also experience rectal bleeding, diarrhea, constipation, or even be unable to completely empty the bowel. Most of these symptoms ado no occur for months after the colon cancer has struck.

The colon cancer early symptoms can tell a person that not everything is right inside the body. The bloating, swelling and pain can be caused by the cancerous tumor pressing against the other abdomen parts. On the other hand the bleeding and thinner stools might result from the waste making its way around the tumor. In most cases, patients commit the mistake of ignoring the symptoms and taking them to be caused by some trivial ailments. Even though this might be true in some cases, it is always advisable to take proper medical advice instead of going for self medication to get temporary relief.

Through proper measures it is possible to treat colon cancer when it is detected in the early stages. However the chances of survival reduce as the cancer advances inside the body. Remember, colon cancer early symptoms, if not taken seriously can prove fatal. On the other, being a little caution can not only save a person from going through the trauma of a painful and deadly disease, but will also help him a long and healthy life. So stop ignoring any unnatural changes in your bowel movements and immediately discuss any such symptoms with your doctor.
