What causes skin cancer?

Answer 1

Your skin type plays a huge role in your risk of getting certain types of skin cancer such as basal cell carcinoma and squamous cell carcinoma as well as melanoma. Basal cell carcinomas are very cureable when removed early. This type of skin cancer does not normally spread to any other parts of the body. Squamous cell carcinoma is cureable when removed early, but it can invade other tissues after a while. Malignant melanoma can occur in any individual or skin type but research has shown that sun exposure increases your risk of this type of cancer. Malignant melanoma can be fatal, but early treatment is essential and can increase your chances of survival. Everyone, regardless of skin type, should protect themselves from the sun by using a high-number sunscreen, wearing a hat, etc. Everyone should also have a complete skin check done at least once a year. Of course, if you have any moles or growths that have changed or bled or look suspicious, you should have them checked immediately! There is the ABCD rule for melanoma. If you have a mole or growth that is "Assymetrical", irregular "Borders", change in "Color" or multi-colored, and "Diameter" of larger than a pencil eraser, GET IT CHECKED! Stay out of the sun.

Answer 2

There are many causes of skin cancer. The most common cause is of course the harmful UV rays from the sun. That's why too much exposure under the sun is very harmful for your skin.

Answer 3

For one Excessive Exposure to Sun. The Ultraviolet-rays can become harmful to your skin;also are the most responsible for sun-ten,and if you stay to much in the Sun you get sun-burn from the UV-rays.
Also UV rays cause eye burns and you eyes hurt,like when you get to the sea-side and can't stand to keep your eyes open.

Sometimes when you want to be 'pretty' you sacrifice and suffer,so happens with sun-ten;use of sun lotions with a higher factor of protection is recommended and also avoid exposure to the sun between 10:30 and 15:30 more or less.

>:) Watch out for those UVs !

Answer 4

Many things can cause it, but one of the most common is too much exposure to the sun. If you have pale skin I suggest wearing lots of suntan lotion when in the sun for long periods of time.

Answer 5

Persons do get skin melanoma in these locations, however since many of the men and women there wouldn't have reasonable epidermis, the sun doesn't fairly impact them all that so much. Sunscreen definitely does not reason dermis melanoma... And i do know this given that i myself have really fair skin, and sunscreen prevents burns, and for that reason prevents dermis melanoma. It can be simply a type of apparent info of life...

Answer 6

My grand-father just died of skin cancer, we think it was from years of us going fishing for hours at a time, in the hot sun.

Answer 7

Sun damage-

How Does The Sun Cause Damage?


The major long term effects of sun exposure are

1. Photoaging
2. Photocarcinogenesis

Photoaging refers to the aging effects of sun on human body. The effects are not only in appearance but the skin actually degenerates at a premature stage -something like fast aging. Why does skin age because of UVR?

With the advancement of free radicals (FR) research, it is now hypothesized that skin disorders due to solar radiation occur because of increased formation of reactive FRs, and impairment of antioxidant system of skin. FRs play an important role in premature aging.

FRs induced damage, results in-

* Degeneration of collagen and connective tissue.
* Fragmentation of elastin.
* Loss of structural and functional integrity of cells of the skin.


How does Sun damaged skin look?

The major long term effects of sun exposure are the sun damaged skin shows dryness, fine lines or wrinkles, roughness and pigmented spots in its mild forms. The moderate damage is manifested by deep wrinkles, laxity and leathery appearance, while in its worst form, the severe damage results in solar keratoses- warty outgrowths on skin and skin cancers.

The other major and worrying long term effect of sun on human skin is-

Photocarcinogenesis- UV induced cancer development.

The role of exposure to direct sunlight in the development of common cancerous conditions of skin is well known. A large number of them are caused by UVB radiation. Actinic keratoses (Precancerous conditions), squamous cell carcinoma, basal cell carcinoma, malignant melanoma are some of the types of cancers associated with prolonged UV exposure.
