Could you know if becker's nevi can turn malignant, and is there any way to get it removed?

Could you know if becker's nevi can turn malignant, and is there any way to get it removed?

Low risk: The skin on a Becker's has only a slightly greater chance than other skin of developing melanoma, and as far as I know no increase for other cancers. Removal with laser isn't going to be perfect. Richard Gere showed his off in lovemaking scenes, other male models / actors have kept theirs, and the several physicians I know who have a Becker's all like them. "That's where a bear licked me!" ...Read more

My dermatologist removed a clarks nevi (?) from my chest. She left a border. Should that be removed now, or should I wait 2 see if there are changes?

Resect and screen: I would remove the whole lesion with clear margins to be safe as there was something concerning about it which warranted the resection in the first place. It is possible that another area of the lesion has cells which have the potential to develop into a tumor. If you have many moles it is important that you also make sure and follow up regularly with a dermatologist for screening. ...Read more
