Many women between the ages of 30 and 50 suffer from breast enlargement. Some of them have been actively treating the disease to stabilize it, while others, especially the younger ones, don’t pay much attention to it. There are also some friends who ask whether breast enlargement can increase the risk of breast cancer, about this series of problems and phenomena, we will talk about it below. Many women are found to have breast hyperplasia during their year-end medical checkups, and data show that about 90% of adult women have different degrees of breast hyperplasia pathology. There is a saying on the internet that “breast enlargement increases the risk of breast cancer”, is this really true? Breast hyperplasia is the most common breast pathology. The World Health Organization refers to breast hyperplasia as “benign breast dysmorphism”, which is not a real disease, but a physiological pathology. Under normal physiological conditions, women’s breast tissue under the action of various hormones will have a cycle of proliferation and regeneration. In the premenstrual period, the glandular cells may proliferate from one layer to three layers, and then return to one layer after menstruation. However, when the body’s endocrine disorders, estrogen levels increase, and endocrine hormones such as estrogen and progesterone are unbalanced, the breast tissues experience excessive hyperplasia or incomplete depreciation, that is, a misalignment of the normal organization of the breasts, and breast hyperplasia is gradually formed. Current research believes that breast hyperplasia does not significantly increase the risk of breast cancer, either in terms of clinical manifestations or pathologic manifestations. However, breast cancer and breast hyperplasia can co-exist, and one should never assume that the presence of breast hyperplasia excludes the risk of breast cancer. Mammal hyperplasia is related to female endocrine dysfunction, especially with estrogen has a great correlation, any drug can only relieve the symptoms, but can not cure the breast hyperplasia. Wells Aiping said that because hormone levels may fluctuate due to endocrine changes, the degree of breast enlargement will also change. Therefore, there may be different physical examination results at different times. The current treatment for breast enlargement is mainly symptomatic, and most of the methods used are endocrine regulation. After menopause, the estrogen level of a woman’s body will drop, at which time breast enlargement will be cured without treatment. Women with breast enlargement should develop good living habits, have a regular routine, do more exercise to enhance their physical fitness, and pay attention to balanced nutrition to help regulate the endocrine system and improve the problem of breast enlargement. Breast enlargement should be treated before it is too late. Breast enlargement belongs to the category of “breast fetish” in Chinese medicine, so it has a certain risk of breast cancer. Breast enlargement is usually categorized into five phases, and if it reaches the third phase upwards, the development trend will be very dangerous for female friends.
