Breast cancer patients are perfectly capable of getting married and should do so, and moreover, they should have a normal sexual life. After all the cancer cells are killed in breast cancer patients, they should also prevent the re-emergence of endocrine disorders, mental and emotional instability and other risk factors that induce breast cancer, just like normal women, and they need to change all their life and physical environment, as well as their mental and emotional state, in order to improve their quality of life. Simply put, it may be that the endocrine disorder induced breast cancer because of unmarried high age, but now that it is cured, we should not continue to let such risks exist, and getting married and having a normal sexual life is beneficial for recovered breast cancer patients. However, the issue of fertility should be considered carefully and it is recommended to discuss it with a doctor. Sexual life should not be too much and too close as healthy people do, and must be a good contraceptive measure, so that pregnancy and abortion cannot occur, otherwise it is not good for breast cancer recovery. In conclusion, all risk factors for the development of breast cancer are also adverse factors affecting the prognosis. Understanding this, post-operative breast cancer patients should know what to do. To lead a normal and healthy life after surgery is more conducive to post-operative recovery.
