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 am having the same problem except it's on my right upper arm.  It's a couple of inches down from the top of my shoulder.  It doesn't hurt, but when I press on it it's kind of squishy.  It's only been like that for about a week.  I'm going to the doctor next week.

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
