Q: I get freckles when I tan. What should I look for to see if the freckle could be a sign of skin cancer?
A: First, you should not purposely get a tan. Any tan from the sun or tanning beds is damage to the skin. The only safe tan is that from a bottle (self-tanners or spray-on tan). Any new spot to the skin should be evaluated. Spots to get worried about are those that are irregular in shape or color or are larger than a pencil-head eraser (4 mm). Spots that bleed easily should also be evaluated.
