What is Skin Cancer?

Skin cancer develops when abnormal skin cells grow uncontrollably. It is the most common cancer in the United States, but when detected early it is highly treatable.

Routine skin examinations and awareness of changes in your skin are important for early detection. Preforming regular self-skin checks and scheduling routine skin exams with your dermatologist can help identify skin cancer early on at its most treatable stage.

Common Types of Skin Cancer

Actinic Keratosis
An early precancerous skin lesion caused by sun damage.
Basal Cell Carcinoma
The most common type of skin cancer, usually found on sun-exposed areas.
Squamous Cell Carcinoma
A common skin cancer that can spread if left untreated.
Melanoma
The most serious form of skin cancer that begins in pigment-producing cells (melanocytes).

About Melanoma

Melanoma develops in melanocytes, the cells that give skin its color. It can occur anywhere on the body regardless of skin tone and may also develop under the nails, in the eyes, or on mucous membranes. Early diagnosis is essential because melanoma is more likely to spread than other skin cancers.


Signs and Symptoms of Melanoma

  • A new or changing mole, spot, bump, or patch
  • Asymmetrical shape or uneven borders
  • Multiple colors or color changes
  • Growth in size or change in appearance
  • Itching, bleeding, or a sore that does not heal
