Sex safe for cancer patients

In general, chemotherapy patients are not forbidden to have sex. However, in practice, many conditions that ultimately will limit the patient to do so. What about safe sex for people with cancer?
Mayo Clinic cancer expert, Timothy Moynihan, MD, said some things to consider before follow that desire, because sexual intercourse in such circumstances is quite a risk. Timothy gave some things to be considered by the patients chemotherapy before having sex:

What type of cancer do you have?
Cancers involving the genital tract may require special caution when it comes to sex. After a procedure or therapy that affects the genital tract, your doctor may recommend abstaining from sexual activity until healing is complete.

What type of chemotherapy are you receiving?
Some types of chemotherapy can lead to changes in the lining of the vagina, which may make vaginal injuries more likely during intercourse. Other types of chemotherapy — such as high-dose chemotherapy after a bone marrow or stem cell transplant — may weaken your immune system to the point that sex isn't a good idea. During intercourse, normal bacteria that live on the skin or in the genital tract may be introduced into your bloodstream. If your immune system is weak, your body may not be protected from these bacteria. Chemotherapy may also increase your risk of bleeding by lowering your platelets, which help with blood clotting. If your platelet count is low, intercourse could cause bleeding. If your platelet count is extremely low, severe bleeding could occur.

Could you become pregnant?
Pregnancy is discouraged during chemotherapy, due to the potential effects on the developing baby. If conception is possible, your doctor will likely encourage you to choose a reliable method of birth control.

Is your partner prepared for a possible allergic reaction?
Theoretically, it may be possible for your partner to develop an allergic reaction to the chemotherapy you've received — although this would be very rare.

Are you feeling up to it?
During chemotherapy, fatigue or other side effects may decrease your interest in sex. If you're not interested in intercourse, remember that there's more to an intimate relationship than sex. Look for other ways to express affection, such as kissing, cuddling or other shared activities.
