Skin cancer is the abnormal growth of skin cells, most often caused by cumulative sun exposure and ultraviolet (UV) damage. Identifying the type of skin cancer is important because treatment recommendations, risk levels, and long-term monitoring can vary from patient to patient.
Symptoms & Causes
Skin cancer can appear in many different forms and may develop anywhere on the body. Warning signs may include:
- New or changing moles
- Non-healing sores
- Scaly or rough patches
- Raised or pearly bumps
- Dark or irregularly shaped lesions
- Growths that itch, bleed, or become tender
Common risk factors include excessive sun exposure, tanning bed use, fair skin, family history of skin cancer, weakened immune system, and a history of frequent sunburns.

Treatment Options
Basal Cell Carcinoma (BCC) Basal cell carcinoma is the most common type of skin cancer and typically develops in areas frequently exposed to the sun, such as the face, neck, scalp, and arms. It may appear as a pearly bump, pink patch, or sore that does not heal. Although BCC usually grows slowly, early treatment is important to prevent tissue damage and deeper spread.
Squamous Cell Carcinoma (SCC) Squamous cell carcinoma often presents as a rough, scaly patch, wart-like growth, or persistent sore. It commonly develops on sun-exposed skin and may grow more aggressively than basal cell carcinoma if left untreated. Early diagnosis and treatment can help reduce the risk of deeper invasion or spread.
Melanoma Melanoma is a less common but more serious form of skin cancer that develops in the pigment-producing cells of the skin. It may appear as a new mole or changes within an existing mole, including asymmetry, irregular borders, multiple colors, or changes in size. Early detection is critical because melanoma can spread to other parts of the body if not treated promptly.
Actinic Keratosis (Precancerous Lesions) Actinic keratoses are rough, scaly patches caused by long-term sun exposure and are considered precancerous growths. While not all actinic keratoses become cancerous, some may progress into squamous cell carcinoma if left untreated.
Rare Skin Cancers Less common forms of skin cancer, including Merkel cell carcinoma and other rare tumors, may also occur. These conditions often require specialized evaluation and treatment planning based on the type and severity of the cancer.
