Types of Skin Cancer

Approximately 1 in 5 Americans get skin cancer by the age of 70. Every year, about 5.4 million people hear this diagnosis, and every hour 2 Americans die from this horrendous disease. This makes it crucial to detect symptoms of skin cancer as soon as possible because the sooner a diagnosis is made and treatment initiated, the greater the chance of getting better.

What Is Skin Cancer?

Skin cancer is a type of cancer where abnormal skin cell growth occurs. The skin is composed of two main layers, namely the epidermis and the dermis. The epidermis, which is the outer layer of the skin, contains three main types of cells, squamous cells, basal cells, and melanocytes. It typically arises in the epidermis and can be classified into three major types: basal cell carcinoma, squamous cell carcinoma, and melanoma.

Although basal cell and squamous cell carcinoma are the most common types, melanoma is the deadliest. Early detection is critical for successful treatment, and it’s important to get regular skin checks by a dermatologist. Other less common types include Kaposi sarcoma, Merkel cell carcinoma, dermatofibrosarcoma protuberans, and sebaceous gland carcinoma.
