Nonmelanoma skin cancer

Nonmelanoma skin cancer refers to all types of skin cancer that are not melanoma. They are the most common type of cancer in humans, and they are generally caused by ultraviolet (UV) radiation from the sun or tanning beds. Nonmelanoma skin cancers include basal cell carcinoma (BCC) and squamous cell carcinoma (SCC), which are the most common, as well as other less common types.

Types

There are two main types of nonmelanoma skin cancer: basal cell carcinoma and squamous cell carcinoma.

Basal cell carcinoma

Basal cell carcinoma is the most common type of skin cancer. It occurs in the basal cells, which are found in the bottom layer of the epidermis. BCCs are often caused by intense, occasional UV exposure, such as a history of sunburn.

Squamous cell carcinoma

Squamous cell carcinoma is the second most common type of skin cancer. It occurs in the squamous cells, which are found in the upper layer of the epidermis. SCCs are often caused by cumulative UV exposure, such as a history of chronic sun exposure and burns.

Risk factors

Risk factors for nonmelanoma skin cancer include:

• Ultraviolet (UV) radiation exposure
• Fair skin
• History of sunburns
• Age
• Male gender
• Immunosuppression
• Certain genetic disorders

Prevention

Prevention of nonmelanoma skin cancer primarily involves protection from the sun. This can be achieved through:

• Wearing protective clothing
• Using sunscreen
• Avoiding the sun during peak hours
• Regular skin checks

Treatment

Treatment for nonmelanoma skin cancer depends on the type, size, and location of the cancer, as well as the patient's overall health. Options may include:

• Surgery
• Radiation therapy
• Topical medications
• Photodynamic therapy
• Laser surgery
