Bowel cancer, I believe many friends are not unfamiliar with it, as long as the onset of bowel cancer is caused by diet, life style and genetics, the age of onset tends to be older and the ratio of men to women is 1.65:1. Today, we will introduce to you in detail what are the symptoms of bowel cancer, hoping to help friends in need.
Main symptoms
At the early stage of bowel cancer, blood is the main symptom, followed by change of stool habit, incomplete bowel movement, and heavy weight, etc. In addition, it is very likely to cause obstruction and intestinal irritation symptoms. There are many prominent clinical manifestations of bowel cancer, so patients need to be more careful. In the early stage of bowel cancer, blood in stool is mainly painless, and the blood is red or bright red, which is very similar to the symptoms of early internal hemorrhoids; in the later stage, blood in stool is mostly dark red, mixed with mucus and blood of stool or pus and blood.
2. Secondly, change of stool habit is a typical manifestation of middle and late stage of intestinal cancer, because the rectal mass and the secretion produced by it can produce intestinal irritation symptoms, resulting in frequent bowel movement, incomplete bowel movement, urgency and heaviness, etc., but the discharge is mostly mucus-pus-blood-like material, and the shape of stool has changed at this time, and the stool is becoming thinner and thinner.
3. Due to the infiltration of cancer around the circumference of intestinal wall, the intestinal cavity is narrowed, especially at the junction of rectosigmoid colon, which is mostly a narrow type of hard cancer, and it is very easy to cause obstruction.
Patients with advanced rectal cancer, due to long-term chronic consumption of the disease, there will be some systemic cachexia. In addition, unexplained anemia appears. Unexplained wasting, weakness and loss of appetite, patients must pay attention to timely examination and treatment in professional hospitals.
4. Bowel cancer often invades surrounding tissues and organs, such as bladder and prostate and other adjacent tissues, causing urinary frequency, urinary urgency and difficulty in urination in late stage. Invasion to the presacral plexus causes pain in the sacrococcygeal and lumbar areas. Rectal cancer can also metastasize to the liver, causing hepatomegaly, ascites, jaundice, and even malignant fluid.
Complications
1.Intestinal obstruction
Intestinal obstruction is the most common complication of intestinal cancer patients. Due to the gradual enlargement of tumor, the intestinal lumen becomes narrower and narrower, and the passage of intestinal contents is obstructed, resulting in mechanical intestinal obstruction. Sometimes it is not caused by the tumor completely blocking the intestinal cavity, but with the increase of tumor, it stimulates the local intestinal cavity to occur inflammatory edema and food blockage, resulting in abdominal pain, abdominal distension, vomiting, anal stoppage of exhaustion and defecation. 70% of intestinal cancer obstruction is located in the left hemicolectomy.
2.Bleeding
Acute bleeding rarely occurs in intestinal cancer because the lesion is closer to the anus, and the blood is mostly bright red or dark red, and the blood and stool are separated. Only when the bleeding is slightly more, the stool is brownish red and jam-like.
3.Intestinal perforation
When the intestine is perforated, it mainly shows the symptoms of acute abdomen, abdominal muscle tension, pressure pain, rebound pain, and x-ray examination can see that the patient has crescent-shaped free gas under the diaphragm.
Perforation may be related to these factors
1, ulcerative and infiltrative type of cancer: this type of intestinal cancer may not occur intestinal obstruction, it is due to excessive tumor growth and insufficient nutrition in the center of cancer cells to cause cancerous tissue to slowly necrosis and fall off, forming intestinal perforation.
2.Intestinal obstruction caused by tumor: the site of intestinal perforation is mostly at the proximal end of the obstruction.
Neuralgia
Neuralgia is the pain caused by the tumor pressing the sciatic nerve or the closed nerve root in the lumbosacral area. After knowing the symptoms of intestinal cancer, you should pay more attention to your body condition, and if any of the above symptoms appear, please follow the doctor’s advice to treat them. You should not believe in prescriptions to avoid bad consequences.
Therefore, you must pay attention to these subtle changes in your future life, which may be the early stage of the disease. Finally, we suggest that if you encounter the above situation, you must go to a regular hospital for treatment in time, so as not to delay the treatment.
