Skin Cancer

Skin cancer is the most common type of cancer affecting Americans. There are many types of skin cancer, but the three most common types are basal cell carcinoma, squamous cell carcinoma, and melanoma. If diagnosed early enough, localized skin cancers can be easily and quickly treated with excellent cosmetic outcomes. Skin cancers that have been discovered later or that behave more aggressively may require more extensive treatment.

If you suspect that a mole, growth, or lesion may be skin cancer, our board-certified dermatologists can help make a diagnosis and develop an effective treatment plan if needed.

Actinic Keratosis

An actinic keratosis is a type of precancerous skin lesion that typically appears as a localized rough, scaly patch. If untreated, they may later develop into squamous cell carcinoma. 

Basal Cell Carcinoma 

Basal cell carcinoma is the most common form of skin cancer and typically presents as a localized red shiny patch, shiny pink bump, or non-healing sore on the skin. These skin cancers typically spread locally at a slow rate in areas that have received chronic sun exposure over many years such as the face, neck, or hands. These skin cancers are important to treat as they can spread although usually only locally in the body.

Squamous Cell Carcinoma 

Squamous cell carcinoma is the second most common form of skin cancer and typically presents as a firm scaly pink bump on the skin. These skin cancers typically spread locally at a slow rate in areas that have received chronic sun exposure over many years such as the face, neck, or hands. These skin cancers have a higher chance of spreading throughout the body than basal cell carcinomas and thus it is important to identify and treat them quickly to prevent an effect on your overall health.

Melanoma 

Melanoma is the third most common form of skin cancer and one of the most aggressive skin cancers.  It is caused when there is an uncontrolled growth of melanocytes (pigment-producing cells) in the skin. Melanoma may present as an irregular appearing mole or odd-shaped or colored brown-black patch on the skin.  This skin cancer can spread very rapidly throughout the body and affect one’s overall health so it is very important to diagnose and treat melanoma as soon as possible
