Basal Cell Carcinoma
As the most common type of skin cancer, BCC looks like a flesh colored, pearl-like bump or pinkish patch on the skin. It forms in the basal cells at the bottom of your epidermis, which is the upper layer of your skin. It is most commonly found on the areas of skin that are exposed to the skin including your ears, arms, legs, face, top of the head and mouth. In most cases, basal cell carcinoma is slow growing, does not spread and is not life threatening.
Squamous Cell Carcinoma
This type of skin cancer can also form as a bump on the skin, but are typically rough to the touch unlike a basal cell carcinoma. It is the second most common type of skin cancer, and people with fair skin are most likely to develop this type.It also tends to form on areas of the skin that are frequently exposed to the sun. Squamous cell carcinoma can grow deep into the skin and spread to other parts of the body.
Melanoma
Melanoma is often considered to be the most serious form of skin cancer due to the tendency to spread to other areas of the body. It can develop in a mole that you already have, or appear suddenly as a dark spot on the skin that looks unusual. Melanoma only makes up about 1% of skin cancers, but causes most skin cancer deaths.
