For general cancers, such as lung cancer, esophageal cancer, breast cancer, stomach cancer, intestinal cancer, etc., as long as the patient is healthy and has normal desires, it is perfectly possible to have sex. As long as the patient does not indulge in sex and has the desire for emotional and physical communication with his spouse, he can have sex. Cancer is not a sexually transmitted disease and will not be transmitted through sexual intercourse. However, if the female partner is suffering from gynecological tumors, such as cervical cancer, vulvar cancer, and the male partner is suffering from penile cancer, prostate cancer, etc., sexual intercourse should be temporarily prohibited during the treatment period, and the doctor’s advice should be sought before starting sexual intercourse after the body has fully recovered from the treatment.
