Male tumor patients, such as those with penile cancer, testicular tumor, prostate cancer, etc., must stop having sex, otherwise sexual intercourse can accelerate the blood circulation of sexual organs and increase the chance of tumor cells spreading through blood and lymph, and it is also bad for the wife’s health. So what is the relationship between these cancers and sex life? It is reported that men under 50 years old who have excessive sex life often increase the risk of prostate cancer. Also excessive use of aphrodisiac drugs can disrupt the balance of endocrine secretion, which is also a major cause of prostate cancer. It has also been found that prostate cancer patients who do not abstain from sex or use aphrodisiac drugs inappropriately are prone to accelerate the deterioration of the cancer. Oral sex often causes HPV-16 infection in genitourinary diseases in the oropharynx, which may have contributed to the increase in tonsillar cancer. And 70% to 90% of penile cancer patients have a history of penile circumcision. And penile cancer is mainly induced by mechanical and inflammatory stimulation, such as more local friction of the prepuce during sexual life. If the foreskin is too long, it often makes the dirt in the coronal groove of the penis stimulate the penis for a long time, which will easily lead to the occurrence of penile cancer. Medical experts suggest that the main predisposing factor for eliminating penile cancer is to remove the overly long foreskin. During treatment: Due to the effect of cancer itself on the organism, as well as the effect brought by surgery, radiotherapy, chemotherapy and other treatments, the patient consumes a lot in terms of energy and nutrition. At this time, the patient is physically weak and should put more energy into the treatment and stop sex temporarily. After the treatment is over, or the consolidation treatment stage after the basic cure: If the patient’s condition is stable and his physical strength recovers well, then it is OK to resume a proper and regular sexual life, so as to harmonize the relationship between husband and wife. As for the frequency of sex life, it should be appropriate according to the patient and the frequency of sex life before the disease as well as the patient’s physical condition, age and disease type, and it is appropriate to have sex without feeling tired the next day. For those patients who have cancer of the penis and other genital organs, and who have disabilities of the external genital organs due to treatment, on the one hand, they can try to do the corresponding forming surgery; on the other hand, they can also compensate for it by talking and having sex with each other in a considerate way. The most important thing is the understanding of both husband and wife. For men, regular sex and ejaculation can effectively reduce the incidence of prostate cancer. Some studies believe that this is because ejaculation helps to discharge potential carcinogenic substances from the body in time. Sex also keeps hormone levels in men’s bodies at a relatively stable range. Sex is not only for intimacy, physical pleasure and fertility, but more importantly, it combines the physical and emotional, and also reduces diseases and helps in longevity. Therefore, the scientific enjoyment of sex is an essential part of a healthy life.
