There are some differences between abdominal pain of bowel cancer and general pain, such as duration and accompanying symptoms. 1. Duration: Abdominal pain caused by bowel cancer will become more and more serious, and it is very likely to cause intestinal obstruction, and as long as the lesion is not treated, the pain will continue. As long as the lesion is not treated, the pain will continue. On the other hand, ordinary pain will be relieved after defecation or anti-inflammatory treatment, and the duration is usually around a few days. 2. Accompanying symptoms: besides abdominal pain, bowel cancer patients may also suffer from loss of appetite, nausea and vomiting as well as weight loss. Comparatively speaking, ordinary abdominal pain may affect appetite due to pain, but will not cause symptoms such as weight loss, besides, ordinary abdominal pain may be accompanied by symptoms such as diarrhea. The above distinction alone cannot clarify whether the pain is general pain or abdominal pain caused by bowel cancer. Patients should consult a doctor in time for colonoscopy or abdominal CT to make a clear diagnosis and give treatment as soon as possible.
