In life, many women feel pain in their breasts from time to time, sometimes light, sometimes not. Breast pain is an experience that most women have had, and some women think of it as cancerous when they encounter pain, while others are not surprised and do not think of it.

The earliest breast pain in women usually occurs at the age of 9 to 13, which is a sign that the girl’s breast starts to develop, first the nipple starts to bulge and there is a slight swelling and pain. After the initial menstruation, it will gradually disappear with the maturation of the breast during puberty. However, if a lump appears in the breast of an adolescent girl, it is likely to be a breast fibroid, which needs to be seen in a hospital. Minimally invasive surgery can easily remove the lump without leaving scars and without affecting the beauty and breastfeeding; it can also be observed regularly and dealt with when waiting for pregnancy preparation. Second, premenstrual breast pain: many women have breast swelling and hardness before menstruation, and the pain is unbearable when touched, physiological breast pain is mostly related to menstruation, premenstrual breast pain is the most common type of breast pain, accounting for about 65% of all breast pain, the average age of onset is 35 years old, the pain mostly appears or worsens 3-7 days before the onset of menstruation, and gradually reduces or disappears after the onset of menstruation.

Premenstrual breast pain may be a sign of breast enlargement. In mild cases, the breasts are swollen, hard and painful with pressure, which can be tolerated and disappear naturally with the arrival of menstruation. In severe cases, the pain is unbearable when the breasts are subjected to slight shocks, such as running or bumping, and the pain does not ease after the end of the period. This is mainly due to the increase of estrogen level in the body before menstruation, breast enlargement and edema of the inter-mammary tissue. After the onset of menstruation, the estrogen level decreases and the above changes disappear. However, there are also breast pains that do not change with the menstrual cycle, have no fixed time and last longer. These women are mostly around 40-45 years old, slightly older than those with physiological pain, and the pain is confined to the breast in a relatively shallow location.

In the case of hard knots, hot compresses can be applied to the breasts before breastfeeding; they can also be used with appropriate draining techniques to promote the smooth flow of the milk ducts. Five, breast pain after abortion: after abortion, some women’s breasts swell and pain, and can be touched lumps. This is due to the sudden interruption of pregnancy, the body’s hormone levels drop sharply, so that the newly developed mammary glands suddenly stop growing, resulting in breast lumps and breast pain.
