Freckle appears possible cancer?

I worked at a dermatologist for 5 years, and dealt with a lot of people who had skin cancer and biopsy's of mole done. I myself had melanoma when I was 25 so I am pretty familiar with it all. First off you will continue to get new and changing moles until you are around 35 years old, so don't be surprised if something new pops up. Freckles will be flat and moles will be raised. Do not be concerned unless you have a freckle or mole that is raised and itchy, changes color, has irregular borders (you should be able to draw a line down the center or horizontal and both sides match) or is larger then the tip of an eraser on a pencil. It is not typical for someone your age to develop skin cancer, but it does happen. Unless you have any of these symptoms I wouldn't worry. If you do have symptoms then just ask for a biopsy at your next visit. They will give you a local numbing medication and shave a piece off to send to a pathologist, usually takes 3 -5 days for results. Hope this helps.
