answered 9/12/2010 I Have An Indent On My Upper Left Arm. It Has Been There For The Past Two Months. No One Nows What It Is. All I Know It Is Getting Bigger. Is This A Possibale Sing Of Skin Cancer? I have a similar problem. The indent is covered by a white spot. My dermatologist said I just needed to massage it daily, but I'm still worried. Its not going away. Please post what your doctor says
