Skin CancersSkin cancer is the most commonly diagnosed cancer in the United states– more than 3.5 million cases are diagnosed annually. One of every five Americans will experience skin cancer during his or her lifetime. Exposure to ultraviolet radiation causes genetic changes in skin DNA which results in uncontrolled growth of skin cells which can form scaly lesions called actinic keratosis which eventually can transform into tumors.
Cancerous skin growths fall into three basic categories:
- Basal cell carcinomas (BCC) are the most common and most treatable. They present as a bleeding pimple like lesion that doesn’t heal, sores, scaly plaques of reddened skin, shiny, pink bumps, or a scar without cause. BCCs are usually caused by cumulative UV exposure, so they are classically seen on scalp, face, ears, neck, shoulders, and back. A BCC can become disfiguring but is rarely life threatening and doesn’t normally spread to other body parts.
- A squamous cell carcinoma (SCC) may appear as a red, scaly plaque, an open sore, or look like a wart. SCCs are also linked to UV exposure over a period of time. Skin injuries, autoimmune diseases, and some medications can trigger their development. Adults over the age of 50 and those who have had a BCC are more susceptible. With early detection and removal, SCCs are usually curable. However, this type of cancer results in about 2,500 deaths each year in the U.S. if allowed to metastasize to other organs.
- Melanoma is the most formidable type of skin cancer. These malignant tumors often look like moles that are changing in size, color, or symptoms. While usually brown or black, they may be pink, red, purple, blue, white, or skin toned. Melanomas are triggered by intense UV exposure (sunburn) and likely have other environmental and genetic factors related to their development. Melanoma readily metastasizes, spreading to other organs. It kills nearly 9,000 Americans annually.
