A lot of brown moles around the chest may be caused by pigmented nevus, seborrheic keratosis, etc., which can be handled by laser, freezing and surgical treatment.
1. Nevus pigmentosus: it is a benign skin tumor of melanocyte origin, which can lead to multiple brown pimples, blotchy rash and other damages around the chest. Benign pigmented nevi usually do not need special treatment, and if they affect the aesthetics, they can be removed by laser. Larger pigmented nevi or nevi with malignant tendency need to be removed by surgery.
2. Seborrheic keratosis: Seborrheic keratosis can be manifested as light brown pimples, plaques, etc., and there may be a lot of brown moles around the chest. Usually no treatment is needed. If the lesions affect the appearance of the skin, they can be removed by cryotherapy, laser therapy and other physical treatments.
If you have a lot of brown moles around your chest, you need to go to a regular hospital in time for examination and treatment.
