Cherry angiomas are harmless, so removal is optional. A lot of people ask what causes these, and we unfortunately don’t have a great explanation in dermatology. They are quite common and we attribute their development to genetics. But there has been an association with hormonal changes (e.g., pregnancy), exposure to certain harsh chemicals (like really bad ones e.g. mustard gas), and there’s limited evidence that sun exposure can aggravate the development of these. If you have them, I would not worry about it. If you have a large one and are not sure if it’s a cherry angioma or not, I recommend talking to your dermatologist.
