About Skin Cancer
Skin cancer occurs when certain types of cells in your skin become damaged, causing them to grow uncontrollably and form tumors.
Every cell in your body contains a microscopic molecule called deoxyribonucleic acid (DNA). DNA contains basic genetic instructions that tell your cells how to function. These instructions govern how your cells behave, grow, and reproduce.
What To Know
Skin cancer forms when the DNA in your skin cells become damaged. This damage may be caused by:
- Exposure to harmful substances, such as UV radiation from the sun
- Genetic mutations inherited from your parents
- Random defects in the cell reproduction process
