A Once A Year Must –

Your Annual Skin Exam

Did you know that skin cancer is the most common form of cancer in the U.S.? In fact, it is estimated that one in five Americans will develop skin cancer in their lifetime. Remember, sun damage is cumulative so as we age so does our risk of skin cancer. That’s why we encourage everyone to take the time to schedule your annual skin exam – just like a dental checkup.

The good news is skin cancer is a treatable condition and when detected early is highly curable.
