Chemotherapy can weaken your immune system, so it is important to consider a few things before starting treatment. If treatment will occur during flu season, it is important to get a flu shot before treatment begins.
Women may wish to have a gynecological exam before starting chemotherapy. A positive result on a Pap test (Pap smear) almost always requires a slightly invasive follow-up procedure. Because chemotherapy can impair the immune system, this type of procedure should take place before treatment starts. Chemotherapy can also interfere with the results of a Pap test.
You should postpone routine dental visits until chemotherapy is over. If you have dental work or a cleaning that cannot wait until after the treatment period, you should go to the dentist before chemotherapy begins.
Although these precautions are important, you should not feel the need to postpone activities such as travel. In general, it is safe to travel by plane, train or bus while undergoing chemotherapy.
