Understanding Skin Cancer: Causes, Types, and Prevention
A Complete Overview of Skin Cancer
Skin cancer remains one of the most prevalent and concerning health issues globally. It can develop on any skin surface, affecting layers like the epidermis, dermis, and subcutaneous tissue. Advanced stages may lead to metastasis, impacting nearby tissues and organs.
Types of Skin Cancer
Keratinocyte carcinomas originate from keratin-producing skin cells, primarily as Basal Cell Carcinoma (BCC) and Squamous Cell Carcinoma (SCC).
Melanoma, arising from melanocytes, is the second most common type and known for its aggressiveness.
Less common forms include Merkel cell carcinoma, Kaposi’s sarcoma, skin adnexal tumors, cutaneous lymphoma, and other sarcomas.
Statistics show that about 50% of individuals will develop either BCC or SCC at some point in their lives. Annually, around 3.5 million cases of these carcinomas are diagnosed nationwide, with approximately 76,000 melanoma cases recorded in 2014. BCC and SCC typically appear on sun-exposed areas like the face, neck, hands, arms, and scalp, though they can also occur internally. Melanoma, although less common, is highly dangerous and more deadly in men. Actinic keratosis, a precancerous condition caused by sun damage, affects over 58 million people in the U.S. and increases skin cancer risk with age. By age 65, half of the population may develop keratinocyte cancers.
Skin cancer primarily affects men over 50, but melanoma is more frequent among individuals aged 25-29. Prolonged sun exposure and fair skin with red or blonde hair heighten risk factors. UV radiation from the sun damages skin cells, leading to mutations and cancer. Family history, tobacco use, autoimmune diseases, organ transplants, medications, and high-altitude living also elevate risk. Recognizable symptoms include unusual bleeding, scaliness, persistent sores, irregular moles, rapid growths, or pain, warranting medical evaluation. Prevention includes avoiding peak sun hours, using sunscreen, and protective clothing. Treatments like surgery, radiation, immunotherapy, and chemotherapy are effective if detected early.
