Where Does Skin Cancer Usually Develop And What Should I Look For?

Skin cancer is usually a painless and makes itself known in several ways. It may present as a growth or irregular area of skin that doesn’t heal within a reasonable amount of time (2 to 3 months). It may also appear in preexisting moles or lesions. The majority of skin cancers develop in areas that are exposed to the sun. However, some may be sneaky and occur in areas that rarely see the light of day. But where exactly do most skin cancers usually develop and grow?

To answer this question, you must first understand that there are a number of different kinds of cancers, and each one has their primary place for development. There are three primary types of skin cancers: basal cell carcinomas, squamous cell carcinomas, and malignant melanomas.

Basal cell carcinomas and squamous cell carcinomas most often appear on areas of the body that are more exposed to the sun. This means that they typically develop on the face, neck, upper chest upper back, and shoulders. Basal cell carcinomas generally have the appearance of a sore or pimple that will refuse to heal, and can ooze yellowish fluids before scabbing over and breaking open again. Squamous cell carcinomas look more like a red or pink-colored growths which may be tender and may break and bleed but never seem to heal.

The third, most concerning type of skin cancer, malignant melanomas, typically form on the legs or the trunk of the body. A melanoma may develop from a harmless appearing mole or freckle, or may present as a brand new spot. They will typically have an irregular shape and be very dark or take on a blend of colors.

It is important to periodically complete a skin self-examination looking for the ABCDEs of colored skin lesions.

A = Asymmetry (one half of the lesion doesn't look like the other half).
B = Border irregularity (the border is not uniform or has a scalloped edge. Also look for the pigment      “spilling out” over the edge.).
C = Color (very dark color or several different colors).
D = Diameter (exceeds the size of a pencil eraser).
E = Enlarging or Elevating.

If you are concerned about unusual growths and developments on your skin you should have it checked out immediately with a dermatologist.
