Cancers

3 main types of Skin Cancers

1. Basal cell carcinoma
2. Squamous cell carcinoma
3. Melanoma

Basal Cell Carcinoma

• Basal cell carcinoma is
the most frequently
diagnosed skin cancer
(2.8 million every year
in U.S.).

Squamous Cell Carcinoma

It is more aggressive than basal and can spread
to other parts of the body and may result in
death (approximately 2,500/year).

Melanoma

• Malignant melanoma is the most deadly of
the three types of cancer.

• Melanoma accounts for less than 5% of the
skin cancer cases.

• It causes more than 75% of the skin cancer
deaths.

• Melanoma causes about 8,790 deaths each
year in the U.S.
