・Does UV rays cause skin cancer?
Have. When people are exposed to ultraviolet light, genes in skin cells are damaged. Normally, damaged genes will be repaired, but if the damage is large due to exposure to large amounts of UV light, the damage may not be repaired.
If the damage caused by UV rays is not repaired properly, the cells will no longer be normal and become the cause of skin cancer.
・Types of skin cancer caused by ultraviolet light
There are a total of 3 main types of skin cancer:
- Melanoma skin cancer
- Non-melanoma skin cancer. This is about 20 times more common than melanoma skin cancer. They are divided into:
Basal cell carcinoma (BCC) – skin cancer that develops from basal cells.
Squamous cell carcinoma (SCC) – skin cancer that develops from keratinocytes.
・Three skin cancer symptoms associated with ultraviolet light
