Most women in late pregnancy may have altered levels of estrogen and progesterone in their bodies, stimulating the mammary glands and ducts to proliferate and secrete milk in preparation for breastfeeding. The accumulation of milk or sebaceous glands at the openings of the milk ducts may result in small rice-grain-like bumps on the skin surface that fall off when plucked. In most cases, this is a normal physiological phenomenon, but with redness, pain or oozing, you also need to consider skin diseases such as sebaceous cysts and eczema. In late pregnancy, due to the increase in estrogen and progesterone levels in the body, women can experience proliferative changes in the breast, which can manifest as swollen breasts and nipples, or swelling and pain. The small duct openings, poor drainage of sebaceous glands, or secretion of milk from the ducts may cause stagnation at the duct openings, resulting in small rice-like bumps on the surface of the breast skin, usually without other symptoms. If there is a grainy bump with redness, swelling, pain, or oozing, a yellowish-white discharge usually occurs when pressure is applied to the bump. If the cyst is severe, the cyst can be removed surgically. If there are small rice-like particles raised on the skin surface of the breast, accompanied by redness, swelling, itching or oozing, you also need to consider the possible occurrence of local eczema, mostly due to allergic reactions. A detailed examination in hospital is needed to exclude allergic factors, and glucocorticoids, antibiotics, antihistamines, etc. should be used under the guidance of a doctor as appropriate to play an anti-inflammatory and anti-itching role, or UV irradiation can be used for relief. The small grains of rice growing on the breasts of women in late pregnancy do not need to worry too much, you need to keep the local skin dry and clean, wash the nipples with warm water, or use a warm towel to gently wipe off the particles raised, do not use your hands to frequently pick out the particles raised on the breasts, which can easily lead to local damage or bleeding infection. Avoid wearing too tight underwear to compress your breasts. You can massage or apply hot compresses appropriately to relieve the symptoms of breast swelling and pain, so as to prepare for breastfeeding after delivery.
