Types of Skin Cancer: Identifying the Most Common Forms
Skin cancer is one of the most common types of cancer worldwide and can develop in various forms, each with unique characteristics and risks. The main types of skin cancer include basal cell carcinoma, squamous cell carcinoma, and melanoma. While some types grow slowly and are less likely to spread, others, like melanoma, can be aggressive and life-threatening if not detected early. Understanding the differences between these types is essential for early recognition, timely treatment, and better outcomes.
What are the Different Types of Skin Cancer?
1. Melanoma Skin Cancer
It is the most serious type of skin cancer that grows in the cells that produce melanin that gives your skin its color. It can be formed in your eyes and sometimes inside your body, such as in your nose or throat.
The cause of melanoma is not clear, but exposure to UV radiation from sunlight and tanning increases the risk of developing melanoma.
2. Non-Melanoma Skin CancerÂ
It refers to all types of skin cancer that occur in the skin that are not melanoma. The most popular types of non-melanoma cancer are basal cell carcinoma and squamous cell carcinoma.
a. Basal Cell Carcinoma
It is a type of skin cancer that begins in the basal cells – a type of cell in the skin that produces new skin as the old ones die.
Basal cell carcinoma often appears on areas of the skin that are exposed to the sun such as the head and neck. Most of them are thought to be caused by long-term exposure to UV radiation from sunlight.
b. Squamous Cell Carcinoma
It is a form of skin cancer that grows in the squamous cells that make up the middle and outer layers of the skin. Though it is not life-threatening, it can be aggressive causing serious complications if left untreated.
 It results from prolonged exposure to UV radiation from sunlight hence avoiding UV light exposure reduces the risk of the disease. It can be found in many places in your body wherever squamous cells are found in the skin.
