Wear a Hat

Melanoma is the most deadly skin cancer. Excessive exposure to ultraviolet light from the sun causes skin cancer, and people with thinning hair should be extra careful when outdoors. Try to avoid being out in the sun during mid-day if you can, and wear a hat to protect the scalp from sun exposure. A broad-brimmed hat is the best sun protection according to Dr. Daniel Berg, director of dermatological surgery at University of Washington Medical Center.

If you do notice a new spot remember the A B C Ds to help with early detection of cancer from the American Academy of Dermatology:

A Asymmetry - Is she spot the same shape on both sides?
B Border irregularity – Does the edge look rough?
C Color varied – Is it one color, and what color is it?
D Diameter – Is it bigger than a pencil eraser?
