Basal cell carcinoma is a cancer that grows on parts of your skin that get a lot of sun. It's natural to feel worried when your doctor tells you that you have it, but keep in mind that it's the least risky type of skin cancer. As long as you catch it early, you can be cured. This cancer is unlikely to spread from your skin to other parts of your body, but it can move nearby into bone or other tissue under your skin. Several treatments can keep that from happening and get rid of the cancer.
