Worried I might have skin cancer? One pink spot looks like a bite but wont go away

See your doctor. Sometimes, it is not easy to differentiate a small basal cell carcinoma. Many times, it looks pinkish-just exactly the same as your skin color.If the spot/growth does not go away, bring it up to your doctor and your doctor can refer you to a dermatologist for better evaluation. Good luck.
Have it checked out. Any spot on the skin which looks abnormal and won't heal up in a reasonable amount of time (2 weeks or so) should be checked out. It may be nothing, but the sooner a cancer is caught, the better the chance of cure.
See a doctor. A pink spot is not likely to be skin cancer, but you should see a dermatologist if it has not gone away.
