Skin cancer signs and risk factors

Skin cancer signs and risk factors

What are the signs of skin cancer?

The severest form of skin cancer is melanoma. The disease develops out of former or newly appeared moles. A few main signs of this type skin cancer should be noticed:

A (asymmetric) – asymmetric moles
B (borders) – moles having anomalous borders
C (colors) – moles of various colors
D (diameter) – moles greater than 6mm in size
E (evolution) – moles that tend to enlarge quickly

It does not necessarily mean that spotting one of these signs announces about the disease but these features are the warning signs of skin cancer.

Not every case of skin cancer is a melanoma. It may also be a non melanoma skin cancer. 

As melanoma so a nonmelanoma skin cancer is mostly probable for light-skinned people. Basal cell carcinoma (basalioma) develops out of deepest skin epidermis basal cells, also may spread to other body parts. First sign of such a skin cancer may just be a small knot of skin color (although it may also appear as a dark knot) that appears on face. Eventually it begins to spread to other body parts and might remind an eczema – reddish, flatty plate that usually appears in the areas of waist, breast, limbs. Patients usually ignore first signs of skin cancer as it does not itch, hurt or is noticeable at all.
