4 Steps to Take If Skin Cancer Runs in Your Family
Having a relative diagnosed with skin cancer like melanoma can naturally be concerning. Read on to learn more about how that affects your risk and the steps you can take to protect yourself.
4 Different Types of Skin Cancer: Signs and Treatments
All skin cancers have one thing in common — the earlier they are caught, the better the prognosis. However, skin cancers differ in their symptoms and treatments.
Fortunately, you can learn what to look for and when to see a dermatologist for diagnosis if anything looks different or suspicious.
At his private practice in Santa Monica, California, Dr. Trevan Fischer provides cutting-edge care from diagnosis to treatment for skin cancer. He stays up-to-date with the latest research and treatment options through his work on clinical trials at the Saint John's Cancer Institute.
Skin cancer
Skin cancer is common and will affect one in five Americans by the time they are 70. Ultraviolet (UV) radiation from the sun or tanning beds damages the skin and plays a role in developing skin cancer.
Types of skin cancer
Skin cancer results from the abnormal growth of skin cells. The type is defined by the location where the cancer begins. There are four main kinds: basal cell carcinoma, squamous cell carcinoma, melanoma, and Merkel cell carcinoma.
Basal cell carcinoma
Basal cell carcinoma begins in the basal cells, found in the skin's outermost layer. It often develops in areas exposed to the sun, such as the scalp, face, ears, neck, shoulders, and back.
This cancer can appear as a waxy or pearly bump or a lesion that could be flat and flesh-colored or brown and scar-like. Alternatively, it could be a sore that bleeds or scabs and then heals, only to return again.
Squamous cell carcinoma
This type of skin cancer often appears in similar areas to basal cell carcinoma. However, unlike basal cell carcinoma, it starts in the skin's squamous cells. It can look like a firm, red nodule or a flat lesion with a scaly, crusted surface or a sore or patch that doesn't heal.
Melanoma
Melanoma occurs in the cells that give skin its color. It can develop in an existing mole or in normal skin. It's often found on the face or torso in men, while it frequently occurs on the lower legs in women. However, it can strike anywhere on the body in areas exposed to the sun and in places not subject to UV radiation.
Symptoms include any spot or mole that is asymmetrical, has an irregular border, has changes in color, is more than one-quarter inch in diameter, or is generally changing or evolving.
Merkel cell carcinoma
Merkel cell carcinoma occurs in the Merkel cells located on the skin's surface. It is typically found in areas exposed to the sun and appears as a painless lump that could be flesh-colored, red, blue, or purple. It could be up to the size of a dime and often grows quickly. People older than 50 or immunosuppressed are at higher risk.
Treatment
Treatment depends on the type. If basal or squamous cell carcinoma is suspected, a biopsy is performed to determine if cancer cells are present. If so, the entire lesion is removed. Spots or lumps that could be melanoma or Merkel cell carcinoma are excised and examined.
Depending on the type, one or more lymph nodes may also be removed to determine if the cancer has spread. The result directs the next treatment steps, which can range from nothing if the cancer is localized to chemotherapy, radiation, immunotherapy, or targeted therapy.
