Skin Cancer
Skin Cancer
Skin Cancer (pronunciation: /skɪn ˈkænsər/) is a type of cancer that originates from the skin. It is the most common form of cancer globally, primarily due to exposure to ultraviolet (UV) radiation from the sun and from tanning beds.
Etymology
The term "Skin Cancer" is derived from the Latin cancer meaning "crab" or "creeping ulcer" and cutis, the Latin term for "skin".
Types
There are three major types of skin cancer:
- Basal-cell skin cancer (BCC)
- Squamous-cell skin cancer (SCC)
- Melanoma
The first two together along with a number of less common skin cancers are known as nonmelanoma skin cancer (NMSC). Basal-cell cancer grows slowly and can damage the tissue around it but is unlikely to spread to distant areas or result in death. Squamous-cell cancer is more likely to spread. Melanoma, on the other hand, is the most aggressive and can spread to other parts of the body, leading to serious illness and death.
Causes
The primary cause of skin cancer is UV radiation from the sun or tanning beds, which damages the DNA in skin cells, leading to mutations and the development of cancer. Other risk factors include a family history of skin cancer, certain types of moles, and a weakened immune system.
Prevention and Treatment
Prevention of skin cancer includes reducing exposure to UV radiation, regularly checking the skin for any changes, and using sunscreen. Treatment options for skin cancer include surgery, radiation therapy, chemotherapy, and immunotherapy.
