If men practice abstinence for a long time, they are prone to prostate diseases. So what happens if women do not have sexual intercourse for a long time? Research experts have given an answer: if women "abstain" for a long time, they are more likely to develop breast diseases... In terms of health and wellness for both sexes, women who "abstain" are more susceptible to breast diseases. Currently, the incidence of breast cancer in Western Europe, North America, and other countries has ranked first among malignant tumors. The incidence of breast cancer in our country is also high, as is the case with Beijing Urology Hospital, where the incidence of breast lobular hyperplasia and breast fibroadenoma is rapidly increasing. Experts have statistically shown that the incidence of breast hyperplasia in women aged 30 to 50 is about 15%, and it accounts for 50% to 70% in breast specialty clinics. Experts indicate that there is a very close relationship between breast hyperplasia and sexual activity. Medical researchers have found through extensive clinical observations that breast diseases are closely related to female sexual activity, and sexual repression in women can increase the likelihood of developing breast lobular hyperplasia and breast tumors. Experts believe that if women always experience sexual arousal without reaching orgasm, they may feel extreme discomfort, and the unreleased sexual tension can easily turn into spasms and pain. From the perspective of traditional Chinese medicine, women who have long-term disharmonious sexual activity tend to get angry easily, which is referred to as liver stagnation and qi stagnation. Qi stagnation leads to blocked mammary ducts and accumulates into habits. Therefore, the quality of sexual activity directly affects the physiological health of a woman's breasts. For women, breasts are not only breastfeeding organs but also sexual organs. During sexual activity, the breasts undergo cyclical changes: during the excitement phase, the breast veins become engorged with blood, the breasts enlarge and become fuller; during the plateau phase, the areola becomes engorged, and the nipples become erect; during orgasm, these changes reach their peak; after orgasm, the engorgement of the areola quickly subsides, and the enlarged breasts gradually return to their original state within 15 minutes. Experts point out that if there is a long-term lack of sexual activity, this physiological regulation will be missing, making it easier to induce breast lobular hyperplasia and breast cancer. Therefore, couples should engage in regular sexual activity. Doing adequate preventive work, having regular physical examinations, paying attention to diet, etc., are all the best ways to prevent breast diseases.
