basaalisolukarsinooma

Basaalisolukarsinooma, also known as basal cell carcinoma, is the most common type of skin cancer. It originates in the basal cells, which are found in the lower layer of the epidermis, the outermost layer of the skin. These cells are responsible for producing new skin cells.

The exact cause of basal cell carcinoma is primarily linked to long-term exposure to ultraviolet (UV) radiation, predominantly from the sun or tanning beds. This damage to the skin's DNA can lead to uncontrolled growth of basal cells. Risk factors include fair skin, a history of severe sunburns, living in sunny climates, older age, and a weakened immune system.

Basaalisolukarsinooma typically appears on sun-exposed areas of the body, such as the face, ears, neck, and hands. It can manifest in various forms, often resembling a pearly or waxy bump, a flat, flesh-colored or brown scar-like lesion, or a sore that bleeds and scabs over but does not heal completely.

While generally slow-growing, basal cell carcinoma can invade surrounding tissues if left untreated. However, it rarely metastasizes, meaning it seldom spreads to distant parts of the body.

Diagnosis is usually made through a visual examination by a dermatologist, often confirmed by a biopsy of the suspicious lesion. Treatment options depend on the size, location, and type of the carcinoma, and may include surgical excision, Mohs surgery, curettage and electrodesiccation, cryotherapy, topical medications, or radiation therapy. Early detection and treatment lead to a very high cure rate.
