Skin Cancer Q & A

What is skin cancer?

Like any cancer, skin cancer is the result of uncontrolled abnormal cell growth. This occurs when DNA damage to skin cells (often caused by ultraviolet radiation from sunshine or tanning beds) triggers mutations or genetic defects. These changes cause the affected skin cells to multiply rapidly and form tumors.

Typically named for the type of skin cell where they originate, the most common forms of skin cancer are:

  • Basal cell carcinoma, the most common, affecting about 1 million Americans annually
  • Squamous cell carcinoma, often appearing as a sore that doesn’t heal
  • Melanoma, the most dangerous form of skin cancer but also very treatable when it’s diagnosed early

Annual skin cancer screening and routine self-exams provide the best method for detecting changes early, when skin cancer treatment is most effective and very often curative.  

Do moles turn into skin cancer?

Most moles remain noncancerous or benign. Made up of cells that provide color in the skin (melanocytes), moles occur when these pigment-producing cells clump together in a certain location. Benign changes in the shape, size, or color of a mole can occur.

A changing mole, however, does require evaluation by your dermatologist because melanoma, the most dangerous form of skin cancer, is caused by abnormal growth in the same cells responsible for moles – melanocytes.

What is skin cancer screening?

During skin cancer screening, Dr. Ding carefully evaluates every inch of your skin for signs of atypical moles or worrisome developments in a previously noted skin lesion. She also checks for precancerous changes known as actinic keratoses. Left untreated, these dry, scaly patches of skin can develop into squamous cell carcinoma.

Who should have skin cancer screenings?

Everyone benefits from skin cancer screening, but annual checks are especially important for those at higher risk of developing skin cancer, which includes individuals with:

  • Fair skin
  • Red hair
  • Family history of skin cancers
  • History of blistering sunburns or long-term sun exposure
  • Long-term immunosuppression due to organ transplant and other health conditions
  • History of radiation therapy

Individuals with a significant number of benign moles are also more at risk of developing skin cancer.

Dr. Ding also provides comprehensive education regarding signs of potentially cancerous skin changes you can watch for at home. She also details practical steps you can take to help prevent skin cancer, such as ways to avoid long-term sun exposure.
