2, premenstrual breast pain: Many women have full, hard and tender breasts during menstrual cramps; In severe cases, a slight shaking or collision of the breast may cause swelling and discomfort, and the original particle or nodule feeling is more obvious. This is due to the increase of estrogen level in premenstrual period, hyperplasia of mammary glands and edema of intermammary tissue. After the menstrual period, the above changes disappear.
3, breast pain during pregnancy: some women are pregnant for about 40 days, due to changes in estrogen levels in the body, so that breast hyperplasia, breast enlargement, and breast pain, severe cases can last the whole pregnancy without treatment.
4, postpartum breast pain: 3 to 7 days postpartum breast pain, induration, pain. This is mainly caused by lymphatic retention, venous filling, interstitial edema and poor mammary duct. Prevention and treatment methods: maternal breastfeeding as soon as possible; When there is induration, you can apply hot compress and massage induration before breastfeeding; You can also use a breast pump to suck milk to promote the patency of the mammary duct.
5. Breast pain after induced abortion: After induced abortion, some women complained of breast pain and could feel the lump, which was caused by the sudden interruption of pregnancy; The hormone level in the body drops sharply, which makes the newly developed breasts suddenly stop growing, causing breast lumps and breast pain.
6, breast pain after sexual life: this is related to the physiological changes of the breast during sexual life. If sexual desire is indifferent or sexual life is not harmonious, the congestion and swelling of the breast will not easily subside, or will not completely subside. Persistent congestion can cause breast pain.
7, breast cancer: common in women aged 20 to 40, the course of disease is slow. In the early stage, there are one or several nodules in the breast, which have no pain or tenderness, and the boundary with the surrounding tissues is unclear. Skin adhesion often occurs, and the axillary lymph nodes on the same side may be enlarged. There is no fever clinically. Abscess softens to form cold abscess; Can penetrate into the skin to form fistula or sinus, discharge thin pus, and contain cheese-like debris. In a few patients, the lump becomes a lump after fibrosis, which changes the appearance of breast and invaginates nipple, which is difficult to distinguish from breast cancer.
8. During the examination, diffuse thickening of both sides of the breast can be found, which is flaky or granular and nodular, and the boundary between the thickened area and the surrounding breast tissue is not obvious; Sometimes the two sides can be asymmetrical, and the above findings are often more obvious before menstruation, and soften or disappear after menstrual cramps. When the cyst is formed, multiple cystic nodules of different sizes can be touched in the breast. The relationship between lobular hyperplasia of breast and breast cancer is controversial, but most scholars believe that more than 90% lobular hyperplasia is a physiological change caused by endocrine disorder, and its essence is neither inflammation nor tumor, nor precancerous lesion. However, there is a phenomenon worthy of attention, that is, some breast cancers are sometimes misdiagnosed as lobular hyperplasia, which has not attracted attention and delayed the opportunity for early treatment.
