After a mole has been picked and bled, the patient can first apply alcohol and iodine to disinfect the wound. If the wound is small, a Band-Aid can be applied locally to protect the wound from infection. If the local wound is large, it can be bandaged at a regular clinic to avoid infection. If the wound is not well protected and infection occurs, the patient should go to the dermatology department or surgery department of a regular hospital for local debridement and antibiotic treatment. If a mole is repeatedly rubbed, causing it to rupture and bleed, it is very wrong, and if a mole is repeatedly stimulated, it is likely to become malignant.
