Have you ever bothered to ponder that how many hours a day you spend exposed to the ultraviolet rays of the sunlight? Do you what disastrous effects it can have on your skin? Have you ever tried to avoid them or to lessen their severity on your skin?

These are few of the questions whose answers are to be in your mind for a good health of the largest organ of your body, the skin. As we all know that excess of everything is bad, so unnecessary exposure to the sunlight is also hazardous to exposed parts of the skin. The ultraviolet rays present in the sunlight leads to a multitude of precancerous and cancerous conditions of the skin. Although genetic and hereditary factors do play an important role in the causation of different types of skin cancer, however, the ultraviolet rays present in the sunlight causes the harm by altering the genetic makeup of the skin cells.

Mole is the most common precancerous lesion. Although not all the types of mole are precancerous, but atypical or dysplastic moles formed due to excessive sunlight are premalignant.

What are the common types of skin cancers?

The common types of skin cancers are squamous cell carcinoma, basal cell carcinoma and malignant melanoma.

Which is the most malignant type?

Malignant melanoma is the most malignant type of skin cancer. Cases have shown that the tumor had already spread at the time of diagnosis.

What are the common signs and symptoms of skin cancer?

Almost all types of skin cancer presents with ulceration and bleeding from the skin, discoloration and disfiguring of already present moles

So, please be careful and avoid unnecessary exposure to sunlight. You stay healthy and good looking always!

2.People in the eastern coast are dark and in the west coast are fair in complexion. Why and which is good?

3. Exposure to sun is advised in some traditional system of healing. Is it good or bad?

4. Sunlight stimulates generation of Vit D. What should be the limit of exposure.
