In the nail breast surgery ward of Wuhan Sixth Hospital, Xiao Qiang, who was ready to be discharged from the hospital, looked at his once abnormally developed breasts in the mirror, and now they not only regained their normal shape, but also could not see any incisions, revealing a smile of satisfaction. Since adolescence, Xiao Qiang found that his breasts were growing, and as a result, he became less confident, reluctant to interact with his classmates and afraid to go swimming. To Xiao Qiang’s relief, the surgery was very successful. Dr. Li Rong, deputy chief of nail and breast surgery at Wuhan Sixth Hospital, the attending physician of Xiao Qiang, said they used a combination of cosmetic and minimally invasive breast lumpectomy techniques to treat Xiao Qiang. The breast lumpectomy is done by making tiny incisions in hidden areas, which is called “scarless surgery” and meets the requirements of male breast development patients who want both health and beauty. Dr. Li Rong, deputy chief physician, pointed out that male breast development is not uncommon, but not all of it requires treatment, especially adolescent breast development, most of which disappears on its own within two or three years. However, if it does not subside over the years, if there are symptoms and the breast enlargement is obvious, affecting the aesthetics or if cancer is suspected, surgery needs to be considered. For men of other ages, if breast development occurs suddenly without a history of special medication but increases rapidly, endocrine hormone-related tumors (most commonly lung cancer) should be considered as a possible cause, and a specialist visit to the hospital is needed to investigate. For middle-aged and elderly men, the appearance of breast lumps, in addition to breast development, may also have the possibility of breast cancer, so it should not be taken lightly.
