I was diagnosed in April 2011 with melanoma on my arch of my left foot. Diagnosed at stage II. I don't understand all of this and have read several postings. I had surgery to remove and had lemph nodes tested. Nodes all came back negative. I have continued seeing dematologist and a cancer specialist. They infomed my that they got it all. How can you rest ones mind. I lost a sister 15 years ago with melanoma as well. Yesterday I found a bump, lump to the left of my sternum. How would you proceed and what do you think I should do?
