###Human: Will waiting for chemotherapy to remove main intestinal cancer cause serious issues? ###Assistant: Hi. Welcome to icliniq.com. It was emergency surgery done to relieve the blockage, complete surgery will be done after chemotherapy because chemotherapy will further shrink the tumor and will make the surgery more feasible. Since surgery is done now, chemotherapy can be started only after healing of surgical wounds which takes 3 to 4 weeks. So, this is the only option. So we need to hope for best and tumor should not spread to distant sites.
