Actinic Keratosis is a precancer to Squamous Cell Carcinoma. If left untreated it has up to a 90% chance of turning into Squamous Cell Carcinoma. These scaling spots feel rough like sand paper and can be found anywhere on the body. When diagnosed, they are simply treated by non-invasive modalities.
Basal Cell Carcinoma is the most common form of skin cancer, affecting 800,000 Americans each year. This cancer usually appears as a small, fleshy bump or nodule and can be found anywhere on the body. If left untreated it can metastasize. These cancers can be seen on anyone, no matter how light or dark your skin tone is.
Squamous Cell Carcinoma is the second most common skin cancer and afflicts more than 200,000 Americans each year. This skin cancer may appear as a bump or as a red, scaly patch. These cancers can be found anywhere on the body and, if left untreated, can have a high rate of metastasizing.
Malignant Melanoma is a more dangerous skin cancer. In 2008, 116,500 new cases of Melanoma were diagnosed and 8,420 of those patients died. In America, 1 person dies from Melanoma every 62 minutes. Melanoma can occur anywhere on the skin, even in places not directly exposed to sun. Therefore, any growing, changing or irregular lesions should arouse suspicion.
