What is the most common form of skin cancer?

Basal cell carcinoma is recognized as the most common form of skin cancer, accounting for a significant percentage of skin cancer diagnoses. This type of cancer originates in the basal cells, which are located in the lowest layer of the epidermis. Factors contributing to its high prevalence include prolonged exposure to ultraviolet (UV) radiation, particularly from the sun, as well as the gradual accumulation of UV damage over time.

Basal cell carcinoma typically manifests as a small, pearly bump or a pinkish patch on sun-exposed areas of the skin, such as the face, ears, and neck. While it is considered less aggressive than other skin cancers and rarely metastasizes to other parts of the body, it can lead to local tissue destruction if not treated in a timely manner.

In contrast, other forms of skin cancer like melanoma and squamous cell carcinoma are less common. Melanoma is known for its potential aggressiveness and ability to spread rapidly; thus, although it is more deadly, it occurs less frequently than basal cell carcinoma. Squamous cell carcinoma, while also a significant concern, occurs with less frequency than basal cell carcinoma. Merkel cell carcinoma, a rare but aggressive skin cancer, is even less common and usually associated with a particular virus.
