Signs and Symptoms of Non-Melanoma Skin Cancer


2. Types of Non-Melanoma Skin Cancer: Basal Cell Carcinoma

As previously mentioned, basal cell carcinoma is the most common type of skin cancer. It accounts for about 75 to 80-percent of all skin cancers, says the Canadian Cancer Society. “It starts in basal cells of the skin, which are round cells found in the top or outer layer of the skin (epidermis). BCC tends to grow slowly. It is rare for BCC to spread to other parts of the body, but it may grow into nearby tissue if left untreated,” writes the source. It typically grows on the parts of the body that are most often exposed to the sun like the face, neck, and head. It is also commonly diagnosed in people who are middle-aged or older.

Similar to squamous cell carcinoma, there are several sub-types of BCC. The most common subtype is nodular BCC, followed by superficial BCC. There’s also infiltrative and micro nodular BCCs which are found in the head and neck area, and lastly morpheaform BCC. We’ll get into the signs and symptoms of each of these later on in the article.
