Less common nonmelanomas (e.g., Kaposi's sarcoma and cutaneous lymphoma) make up less than one percent of nonmelanoma cancers. Squamous cell carcinoma is more aggressive than basal cell carcinoma and more likely to spread to other parts of the body. However, it can also develop in other locations, including the genital area. Between 35 to 50% of people who develop one basal cell carcinoma will grow a new skin cancer within five years of diagnosis.Īccounting for about 20% of all skin cancers, squamous cell carcinomas also form on the top, thin layer of the skin and are commonly seen on sun-exposed areas such as the face, neck, lips, neck or back of the hand. After treatment, basal cell carcinoma may grow again on the same spot or appear elsewhere on the skin. They are slow growing and do not usually spread. About 75% of all skin cancers are of this type. It is usually found on the sun-exposed areas of the body, such as the neck and head. Basal cell carcinoma forms in the thin, upper layer of the skin (epidermis). Nonmelanoma Skin Cancer - The the most common types are basal cell carcinoma and squamous cell carcinoma. There are two main types of skin cancer: malignant melanoma and nonmelanoma skin cancer Between 40 to 50% of all cancer cases diagnosed every year are skin cancer.
