There is no clear clinical data to show how many times a day bowel movement is caused by bowel cancer, usually there are no obvious symptoms in early stage patients, and some patients may have diarrhea, constipation and other changes in bowel habits. Usually, early stage bowel cancer patients have no obvious symptoms, the number of bowel movements is the same as usual, 1 time/day or 1 time/2 days, only some patients may have diarrhea, constipation and other changes in bowel habits, which may also be manifested as bloody stool, mucus stool, thinning of fecal strips, etc. However, there is no clear data to show that how many times a day the patients have bowel movements, which may vary from 2-5 times/day or 1 time/3-4 days, which is not exact. And bowel cancer can also be categorized into rectal cancer, left half colon cancer and right half colon cancer. Generally, patients with rectal cancer may also have internal urgency and a feeling of incomplete bowel movement, etc. As the cancer grows in a ring-like manner, intestinal luminal obstruction may also occur. Meanwhile, patients with left half colon cancer will routinely cause complete or partial intestinal obstruction, which is mostly manifested as no anal emission, no defecation, abdominal pain and abdominal distension. In case of right half colon cancer, abdominal mass, emaciation, abdominal pain and other symptoms may also appear, and if patients are combined with anemia, they may show weakness, shortness of breath, fatigue and so on. In addition, if intestinal cancer invades into surrounding tissues or organs, corresponding symptoms can also appear, such as invasion to sacral plexus, continuous pain in lumbosacral region, invasion to prostate gland and bladder, etc., which can also induce urinary frequency, urinary urgency and hematuria. If the tumor metastasizes to liver, lungs, bones and other parts, jaundice, respiratory difficulty, bone pain and so on may also occur. In conclusion, bowel cancer patients’ bowel movements are not exact, so it is suggested that bowel cancer patients pay more attention to their symptoms and actively cooperate with doctors to take targeted treatment.
