When Weiwei (a pseudonym), 38, was taking a shower, she accidentally found a hard lump on her right breast, which did not cause much pain, and was examined and found to be “breast enlargement”. She had heard from her mother-in-law that breast enlargement could turn into breast cancer, but after my detailed explanation, she finally understood that breast enlargement and breast cancer are two different things. …. What is breast enlargement? Breast enlargement is a common gynecological symptom, it is estimated that about 70% of women have the phenomenon of breast enlargement, the main reason for endocrine disorders or physiological menstruation caused by, for example: the body of estrogen, luteinizing hormone (progesterone) concentration fluctuations in the epithelial cell nuclei in the breast ducts fibroblasts, caused by the structural disorders of the mammary gland, resulting in the mammary glands larger than normal glands. Most of the time, this condition will be cured after menopause. Only a very small number of people with moderate or severe atypical breast hyperplasia may develop breast cancer. What is the difference between breast hyperplasia and breast cancer? 1, the softness and hardness of lumps are different: the hard lumps of breast hyperplasia are usually softer in texture, because they are just thickened breast glands, which are usually of different sizes, in the form of flaky or nodular bilateral movable soft lumps; while the tumors of breast cancer are usually hard like stones and have poor mobility mostly unilateral, the boundary between the surrounding tissues is blurred, and it is very easy to hyperplasia. 2, breast hyperplasia and breast cancer attack pain is different: because the general breast hyperplasia, is with the physiological period of the body’s hormonal concentration of changes in cyclic pain, usually in the pre-menstrual distension, and pre-menstrual pain subsides, which is commonly known as pre-menstrual distension of the milk. And this phenomenon will become serious with late night, work pressure or mood tension, it is recommended that you can adjust the diet and mood, will all improve. For very painful patients, medication may be recommended in some cases. For breast cancer patients, they do not feel pain in the early stage, but in the end stage, the pain is caused by the tumor spreading to the outer envelope or skin. If you want to judge breast cancer, you can pay attention to whether there are breast skin depression, thickening, roughness and nipple retraction, erosion or asymmetry, or even bloody nipple overflow, etc., which need special attention. Only a very small number of atypical breast hyperplasia can lead to breast cancer Atypical breast hyperplasia refers to the abnormal proliferation of epithelial cells, which is manifested by the proliferation of cells of different sizes and forms; it can be categorized into ductal epithelial atypical hyperplasia originating from breast ducts and lobular atypical hyperplasia of the lobules of the mammary glands. According to the data, patients with ductal epithelial or lobular atypical hyperplasia are 5 to 18 times more likely to develop breast cancer than normal women. However, such atypical breast hyperplasia can be said to be only an intermediate process from benign to malignant, and if it is actively treated and monitored in a timely manner, its progression will be stopped and there is a chance that it will return to normal. Clinically, atypical breast hyperplasia is 10%, of which only 30% will lead to breast cancer, so patients should not panic too much.
