The most common type of skin cancer is non-melanoma skin cancer. Now called keratinocyte cancer, basal cell carcinoma and squamous cell carcinoma are the most widespread. These skin cancers usually occur on areas of the body often exposed to the sun—such as the face and neck.
Basal cell carcinoma accounts for about 70% of keratinocyte cancers. Common sites for basal cell carcinoma on the face are the nose, cheeks, forehead, nasolabial folds (the creases running from either side of your nose to the corners of your mouth), and eyelids. While it tends to grow slowly, if undetected it can grow deep into the skin, making treatment more difficult.
Squamous cell carcinoma is the second most common type of skin cancer. It accounts for around 30% of keratinocyte skin cancers. Frequently sun-exposed areas such as the lips and ears are especially likely to develop squamous cell carcinoma. If undetected, squamous cell carcinoma may spread to other parts of the body.
It’s worth knowing that most squamous cell carcinomas begin as an actinic keratosis.This is a precancerous spot that forms on sun-damaged skin. It appears as a rough dry, scaly patch of skin. If detected, it can be treated to prevent it from progressing into squamous cell carcinoma.
Melanoma, the most aggressive type of skin cancer. While it only accounts for around 3% of all skin cancer diagnoses, it is the most deadly. Like keratinocyte skin cancer, it most often develops on areas of skin that have been exposed to the sun. Common sites for melanoma skin cancer on the face and head are the cheek, neck and ear.
