basaalrakkkartsinoom

Basaalrakkkartsinoom, also known as basal cell carcinoma (BCC), is the most common form of skin cancer. It originates in the basal cells, which are found in the lower part of the epidermis, the outermost layer of the skin. BCC typically develops on sun-exposed areas of the body, such as the face, ears, neck, and hands.

This type of skin cancer is characterized by slow growth and rarely metastasizes, meaning it usually does not spread to other parts of the body. However, if left untreated, it can grow deeply into the skin, damage surrounding tissues, and cause disfigurement.

The primary cause of basal cell carcinoma is long-term exposure to ultraviolet (UV) radiation, mainly from sunlight and tanning beds. Individuals with fair skin, a history of sunburns, or a weakened immune system are at higher risk. Other risk factors include age, a family history of skin cancer, and exposure to certain chemicals like arsenic.

Basal cell carcinomas can appear in various forms. Common presentations include a pearly or waxy bump, a flat, flesh-colored or brown scar-like lesion, or a sore that bleeds and scabs over but doesn't heal. Early detection and treatment are crucial for successful outcomes.

Diagnosis is typically made through a physical examination and a biopsy, where a small sample of the suspicious lesion is removed and examined under a microscope. Treatment options depend on the size, location, and type of BCC, and may include surgical excision, Mohs surgery, curettage and electrodesiccation, cryotherapy, topical medications, or radiation therapy. Regular skin checks and sun protection are essential for prevention and early detection.
