Bowel cancer may be able to touch the mass on the stomach, depending on the size of the tumor and the thickness of the patient’s abdominal wall. In the middle and late stage of bowel cancer, if there is a large area of tumor metastasis or the tumor volume is too big and the patient’s abdominal wall is thin, a lump can be touched in the abdomen, which is usually difficult to be touched in the early stage of the disease. At present, in the physical examination of patients with bowel cancer, rectal finger test is mostly used, in which the doctor will stick his finger into the patient’s anus to check whether there is any mass in the rectum, and if he wants to set up further effective treatment plan, he also needs to complete endoscopy with biopsy, laboratory examination (such as fecal occult blood, tumor marker examination, etc.), and imaging examination (such as barium meal X-ray, CT, etc.), and so on. It is important to note that bowel cancer patients can reduce the adverse effects of the disease and improve the prognosis through “early detection, early diagnosis and early treatment”. Therefore, if patients suspect bowel cancer or have other discomforts, they should consult the doctor in time.
