Symptoms of rectal cancer may include intestinal obstruction

Symptoms of rectal cancer may include intestinal obstruction. After this phenomenon occurs, the body will feel abdominal pain and bloating. If you have these symptoms, don't think it's accidental. So what are the symptoms of rectal cancer ? Let the experts explain it to you in detail.

In the late stage, rectal cancer often invades surrounding tissues and organs, such as the bladder and prostate, causing frequent urination, urgency and difficulty urinating, invading the presacral nerve plexus, and causing sacral and lumbar pain. Rectal cancer can also metastasize to the liver, causing symptoms such as liver enlargement, ascites, jaundice, and even cachexia.

In addition to the common systemic symptoms such as loss of appetite, weight loss, anemia, and other local symptoms of rectal cancer, there are also other local symptoms, as follows:

1. A lump may be felt during digital rectal examination. Patients with advanced rectal cancer may have increased bowel movements, incomplete bowel movements, frequent urge to defecate, tenesmus, and other local irritation symptoms of the cancer.

2. Due to the enlargement of the tumor in the late stage of rectal cancer, the intestinal cavity narrows and intestinal obstruction occurs. When the intestinal cavity is completely blocked, symptoms of rectal cancer such as constipation, abdominal distension, and abdominal pain appear.

3. When the advanced cancer further expands, it will invade surrounding tissues and organs, causing patients to have difficulty urinating, frequent urination, and painful urination. When the cancer invades the presacral nerve plexus, sacral and lumbar pain will occur; when it metastasizes to the liver, it will cause hepatomegaly, ascites, jaundice, and even cachexia, which are symptoms of rectal cancer.

4. Another typical symptom of rectal cancer is increased intestinal secretions, which is caused by irritation of the intestinal mucosa. A small amount of mucus secretions will be discharged with the stool, and there will be strips of mucus on the surface of the stool. As the tumor continues to develop, the irritation to the rectal mucosa will be greater, and the patient will feel mild discomfort in the rectum, or often have a sense of emptiness. In the late stage of rectal cancer, when the surface of the tumor ulcerates, the stool will be thinner and may be like water mixed with mucus and blood.

The above is the explanation given by experts on the symptoms of rectal cancer. I hope it can help you answer your questions. Experts suggest that some diseases have no early symptoms or are not obvious. For your health, the best way is to have regular physical examinations to detect the disease early and prescribe the right medicine.
