How long does chemotherapy stay in your system?
How long does chemotherapy stay in your system after all treatments?
While the effects of chemotherapy can take place over a longer period of time (maybe weeks), the actual chemicals that are chemotherapy are generally out of the person's system within 24 hours. This assumes that the person's kidneys and liver are able to process the chemotherapy within a normal period of time
If that is the case then why does it take 3-5 days after chemotherapy to get the cold/mouth sores and such? Seems to me that it stays in your body longer than that.
