Is it normal to lie flat on the stomach? Is this common malignant tumor of colon cancer, which is more likely to occur in elderly males? The occurrence of the disease is closely related to lifestyle, genetics, colorectal adenoma, etc. Generally, there are no obvious symptoms. As the tumor grows, the patient will have abdominal pain, blood in the stool, abdominal mass, etc. So, is it normal for the bowel cancer to lie flat on the stomach?

　　Intestinal cancer lying on the stomach The sense of oppression indicates that the tumor has oppressed the organs, the condition is more serious, and it needs to be actively treated. The occurrence of bowel cancer is related to a high-fat, low-cellulose diet, chronic inflammation of the large intestine, colorectal adenoma, genetic factors, and other factors such as schistosomiasis, pelvic radiation, environmental factors (such as molybdenum deficiency in the soil), and smoking.

　　Intestinal cancer is asymptomatic at the early stage, or the symptoms are not obvious, only feeling uncomfortable, indigestion, stool occult blood, etc. As the cancer develops, symptoms gradually appear, manifested as changes in stool habits, abdominal pain, blood in the stool, abdominal mass, intestinal obstruction, etc., with or without systemic symptoms such as anemia, fever, and weight loss. Tumor metastasis and infiltration can cause changes in affected organs. Intestinal cancer shows different clinical symptoms and signs because of its different locations.

　　The most common form of infiltration of intestinal cancer is local invasion, and the tumor invades the surrounding tissues or organs, causing corresponding clinical symptoms. Anal incontinence, persistent pain in the lower abdomen and lumbosacral region are caused by rectal cancer invading the sacral plexus. The tumor cells are implanted and transferred to the abdominal pelvis to form the corresponding symptoms and signs. The digital rectal examination can palpate the mass in the bladder rectum or uterine rectum fossa. The tumor is widely implanted and transferred in the abdominal pelvis to form peritoneal effusion.

　　The treatment plan for colon cancer is a comprehensive treatment plan based on surgical resection. Patients with stage Ⅰ, Ⅱ and Ⅲ often use radical resection + regional lymph node dissection, and determine the scope of radical resection and the surgical method according to the location of the cancer. If patients with stage IV intestinal obstruction and severe intestinal bleeding do not undergo radical surgery temporarily, palliative resection may be performed to relieve symptoms and improve the patient''s quality of life.

　　The current effect is better, more research is comprehensive treatment of surgery and radiotherapy, including preoperative radiotherapy, intraoperative radiotherapy, postoperative radiotherapy, "sandwich" radiotherapy, etc., each with its own characteristics. For patients with advanced bowel cancer, local tumor infiltration, and surgical contraindications, palliative radiotherapy should be used to relieve symptoms and relieve pain.
