Facts about Skin Cancer

Sun can cause skin cancerWhat are the types of skin cancer?

Basal cell carcinoma and Squamous cell carcinoma: These are the most common forms of skin cancer and typically appear on sun-exposed areas of the body, usually on the face, ears, bald scalp, neck, and arms.

Melanoma: This is the most deadly form of skin cancer, and can appear anywhere on the body. This is the type of skin cancer that can spread to the lymph nodes and internal organs of the body, which makes early detection and treatment essential.

What should I watch for on my skin to detect skin cancer early?

Basal cell carcinoma and squamous cell carcinoma often appear as a new bump or ulcer on your skin that does not heal.

Melanoma often presents as a new, rapidly growing mole or a mole that is changing shape or color.

If you see anything worrisome for skin cancer on your skin, seek the attention of a board-certified dermatologist immediately because early detection gives you the best chance for a cure.

Individuals who have increased exposure to ultraviolet light from the sun or indoor tanning devices are at increased risk for skin cancer. (Please read our article on Sun Protection)

  • Red or blonde hair, or blue or green eyes
  • Greater than 50 moles, large moles, or unusual moles
