In the last year or two, women in their 30s are frequently found to have breast cancer in hospital outpatient clinics. Survey data shows that the incidence of breast cancer in major cities in China has increased by 37% in the past 10 years, especially in the age group of 30-54 years old, and breast cancer has become the “number one killer” threatening women’s health. Sexual repression in women can increase the incidence of lobular hyperplasia and breast tumors. During the female sexual response cycle, there are obvious changes in the breasts, such as nipple erection and breast enlargement and swelling. Women who are always sexually aroused but cannot reach orgasm will feel extreme physical discomfort, and the unreleased sexual tension can easily evolve into cramps and pain. The quality of sexual life directly affects the physical health of women’s breasts. As the second sexual characteristic of women, breasts are an indispensable factor in arousing male sexual desire while giving women sexual stimulation. After breast cancer surgery, the ability to bear the psychological pressure of breast absence is very important to maintain a harmonious couple life. In fact, breast cancer patients are perfectly capable of having a normal sex life after recovery. Most of the breast cancer patients’ reduced sexual desire after surgery is affected by both physical and psychological factors: whether it is surgery or radiotherapy or chemotherapy, it will trigger the patient’s physical weakness and mental lethargy. Especially, chemotherapy drugs can also inhibit women’s ovarian function, thus causing the loss of their sexual desire. On the other hand, in addition to the lack of confidence in sexual life due to the absence of breasts, which brings women to fear that they cannot meet the sexual demands of their husbands, the fear that sexual life will contribute to the recurrence of cancer is also an important factor that prevents patients from having a normal sexual life. Moderate sex life is conducive to maintaining the balance of endocrine function of patients, and it can also harmonize the relationship between husband and wife, make both parties happy, improve the immune function of the body, enhance the confidence of patients to overcome the disease, and even effectively prevent the recurrence of breast cancer.
