It depends on the stage of the cancer; non metastatic cancers completely removed by surgery still benefit from chemo - if you tell me your stage i can direct you to accurate information. You may find the information you seek here:


Do you recommend a colorectal cancer patient do cleanup chemo even if the tumor and cancer are completely gone after chemo/radiation and there was never any metastasis since diagnosis. What type of percentages of how the cleanup chemo will actually prevent the cancer from coming back? Is it even worth it doctor? Thanks for your time.
