“How long is your immune system compromised after chemo and radiation?”

I am not sure but after cancer treatment, in general your immune system will not be the same. Radiation treatment seems to be less problem than chemotherapy and shorter duration.

Hi,

This is Dr. Iddings, I am a surgical oncologist. There is no absolute answer to this question, but a sensually we typically wait one month after chemotherapy before doing a had major surgery and that is considered recovery enough to take on a major surgery and he'll reasonably well. That truth of it is probably a little longer before there is absolute full recovery but the recoveries pretty good after a month and after 3 months you should be feeling pretty good. You may not recover fully from chemotherapy as there are some side effects to some chemotherapy is like numbness that may never go away. Essentially, it is a new normal and you will get there 1 to 3 months after chemotherapy has been as. Radiation on the other hand has long lasting effects that get worse and worse so there certainly is no full recovery after radiation and there is also a new normal there.
I hope that helps. The short answer is about a month.

It depends on the individual. For people taking chemotherapy the immunity usually recovers before the next treatment. In general, the immunity should have fully recovered in seven to ten months after treatment

Not all chemotherapy suppresses immunity. The length of time immunity is suppressed depends upon type of chemotherapy, total dose, and dose of radiation and what parts if body are radiated.

Radiation does not affect the immune system if it is not treating large amounts of bone marrow, as it is not spreading outside the treated areas. Chemotherapy induced immunosuppression depends on the agents involved and may last weeks to months.
