The rice-grain-like substance that falls out of the patient’s breast is usually fatty grains on the breast or breast gland secretions, which are not accompanied by pain. It is recommended that patients do not pluck out the small grain-like substance that falls off at the breast, and do not use unsterilized nails, tweezers, etc., to prevent infection of the breast area, causing mastitis and other breast diseases. 1, fat grains: the patient’s sebaceous glands at the breast secrete too much oil, and not timely cleaning, thus forming fat grains on the skin surface of the breast, like small grains of rice that fall off at the first pluck. If the patient has too many fat grains, you can get rid of the fat grains at the breast through laser therapy or cryotherapy under the advice of a doctor, and usually pay attention to moderate cleaning of the breast area to reduce the accumulation of grease at the breast; 2, breast gland secretions: the small rice-grain-like material that falls off at the breast may also be due to the fluid secreted by the glands at the breast, such as breast overflow, breast milk, etc., which accumulates at the breast.
