External Signs of Internal Problems

If you notice bumps on the skin, don’t assume they’re merely blemishes. New, abnormal freckles may indicate skin cancer and should be looked at by a dermatologist. But bumps or lumps may have other causes. Any unusual softening or hardening of the skin could indicate an underlying medical problem. The American Academy of Dermatology says waxy or yellow bumps may be a sign of high triglycerides — often an indicator of uncontrolled diabetes. See your dermatologist if you notice any unusual skin changes.
