Whether sigmoid colon cancer will recur or not and how many months it will recur cannot be inferred, as each patient’s situation is different and cannot be inferred effectively. Sigmoid colon cancer is a kind of malignant gastrointestinal tumor disease which is relatively common in clinic nowadays. Early stage sigmoid colon cancer patients can use surgical treatment to resect diseased intestinal segments and carry out postoperative radiotherapy and chemotherapy, which can possibly remove the cancer cells completely. Sigmoid colon cancer may still recur after complete elimination, which is related to the patient’s genetics, dietary habits and other factors, but it is not possible to effectively deduce the time of recurrence of sigmoid colon cancer. However, sigmoid colon cancer does not always recur, so patients need not be too nervous, and after the operation of sigmoid colon cancer, patients can undergo regular checkups, and if any abnormality is detected, timely treatment can be carried out.
