Skin Cancer

Types of skin cancer

Skin cancer is the most common type of cancer in the United States and generally falls into two categories: melanoma and nonmelanoma skin cancer. The most common nonmelanoma skin cancers are basal cell carcinoma (BCC) and squamous cell carcinoma (SCC). Melanoma is less common but considered the most serious form of skin cancer due to its ability to spread if left untreated. When detected early, most skin cancers are highly treatable, making regular skin checks and early evaluation important.

Basal cell carcinoma is the most common type of skin cancer, developing in the basal cells located in the deepest layer of the skin’s outer surface. It is most often caused by cumulative sun exposure and may appear as a pearly bump, pink patch, or sore that does not heal. Although it rarely spreads to other parts of the body, early treatment is important to prevent continued growth and damage to surrounding tissue.

Squamous cell carcinoma is a common type of skin cancer that develops in the squamous cells, which make up much of the skin’s outer layer. It is most often caused by cumulative sun exposure and commonly appears as a scaly patch, sore, or growth that may crust or bleed. While highly treatable when detected early, some cases can grow deeper or spread if left untreated.

Malignant melanoma is the most serious type of skin cancer, developing from pigment-producing cells called melanocytes. It has the potential to grow quickly and spread to other parts of the body if not detected and treated early. Early diagnosis is important, as melanoma is highly treatable when caught in its earliest stages.

Annual skin cancer screenings are an important part of maintaining healthy skin and identifying concerning lesions as early as possible. At American Skin Institute, our dermatology team recommends scheduling a comprehensive annual skin exam to evaluate for signs of skin cancer and other abnormal skin changes. Monthly skin self-checks are also encouraged, as early detection allows many skin cancers to be treated more effectively. If you notice a new, changing, or concerning spot on your skin, do not delay seeking evaluation. With convenient office locations in Sherman Oaks and Westlake Village, American Skin Institute provides expert skin cancer screenings, diagnosis, and treatment in a patient-centered environment.
