Most skin cancers are caused by long term exposure to the sun. There are two types of non melanoma skin cancer, basal cell carcinoma (BCC) and squamous cell carcinoma (SCC). A history of sunburn increases the risk of BCC. Risk is especially high if you had several episodes of sunburn in childhood. The risk of SCC is linked to overall sun exposure through your life. This means that outdoor workers have an increased risk, such as, farm workers, gardeners and building site workers. Sunburn in childhood is also linked to SCC in some studies.

Fair skinned people, with light coloured hair and eyes, or those more likely to burn than tan, are more at risk of sun damage than dark skinned people.

To protect our-self from harmful UV rays we must use UV blocker umbrella.

Skin Cancer Causes

Ultraviolet (UV) light exposure, most commonly from sunlight, is overwhelmingly the most frequent cause of skin cancer.

Other important causes of skin cancer include the following:

* Use of tanning booths

* Immunosuppression—impairment of the immune system, which protects the body from foreign entities, such as germs or substances that cause an allergic reaction. This may occur as a consequence of some diseases or can be due to medications prescribed to combat autoimmune diseases or prevent organ transplant rejection.

* Exposure to unusually high levels of x-rays

* Contact with certain chemicals—arsenic (miners, sheep shearers, and farmers), hydrocarbons in tar, oils, and soot (may cause squamous cell carcinoma)
Regarding your mother's comment, people who had at least one severe sunburn early in life have a greater risk of developing skin cancer. Mom is right!
Treatment for basal cell carcinoma and squamous cell carcinoma is straightforward. Usually, surgical removal of the lesion is adequate. Malignant melanoma, however, may require several treatment methods, including surgery, radiation therapy, and chemotherapy.

I know and understand the arguments about sun exposure and skin cancer and I think they do make sense but are a partial explanation, imho. There are correlation charts for skin cancer rates and the introduction of specialist sun block creams from the 1980s (when education on skin protection against skin cancer was kicking in). Skin cancer rates have continued to increase suggesting that either the creams and education don't work or there is some other cause.
I don't claim to be a medical expert but I have carefully researched this, and have more than just a passing interest because of personal experience.
I would suggest that skin cancers have some relation to cancers in general. This is the theory. I won't say it is in any sense "mine" I am just repeating the research of others.
Factors like genetics, toxicity in the environment, drug consumption, smoking and the internal chemistry of the body (particularly the pH balance - acid being bad) will at times in a person's life overload the immune system and create a tipping point where cancers that the immune system would normally surpress, take over the body. Once we get to this stage it is normally far too late. I would suggest that nearly all of us are fighting some sort of battle against cancer right now. If we make it easy for our immune system to deal with abnormal cell reproductions on a small scale we are never likely to experience a cancer.

AlexA, I am in total agreement that there is more to skin cancer than sun exposure. I believe that current medical thought focuses too much on the inciting incident, ie UV exposure and not enough on the actual problem, which is why our bodies are not destroying the cancer. My latest theory is that certain blood types have a tendency to produce too much fibrin, the substance that coats the cancer and keeps it from being recognized by the immune system. Eating blood thinner foods like garlic, ginger, etc might help us prevent reoccurrences. II wonder how many of us on this forum are blood type A, B or AB, the blood types associated with a tendency to clot more.
