Hi,I am Dr. Shanthi.E (General & Family Physician). I will be looking into your question and guiding you through the process. Please write your question below.
I am a 46 year old female hispanic who has had manicures all my life, recently I noticed a light grey line in my thumb nail running from the top to bottom of my nail. After going online i see so much about melanoma, I have contacted my doctor for a appointment but is there any other causes?
