Squamous cell skin cancer

Squamous cell skin cancer is a type of skin cancer that originates from the squamous cells in the skin. It is the second most common type of skin cancer, following basal cell carcinoma. Squamous cell skin cancer is usually caused by prolonged exposure to ultraviolet (UV) radiation, either from the sun or from tanning beds.

Causes

The primary cause of squamous cell skin cancer is exposure to UV radiation. This can come from the sun, tanning beds, or other sources. Other risk factors include having light-colored skin, a history of sunburns, a weakened immune system, and exposure to certain chemicals.

Symptoms

Squamous cell skin cancer often appears as a firm, red nodule or a flat lesion with a scaly, crusted surface. It most commonly occurs on areas of the body that are exposed to the sun, such as the face, ears, and hands.

Diagnosis

Diagnosis of squamous cell skin cancer typically involves a skin biopsy. This involves removing a small sample of skin and examining it under a microscope to check for cancer cells.

Treatment

Treatment options for squamous cell skin cancer depend on the size, location, and aggressiveness of the tumor, as well as the patient's overall health. Options may include surgery, radiation therapy, and topical medications.

Prevention

Prevention strategies for squamous cell skin cancer include avoiding excessive sun exposure, using sunscreen, and wearing protective clothing.
