What are the symptoms of early bowel cancer?

According to clinical observation, some intestinal cancers occur on the basis of rectal polyps or schistosomiasis; chronic inflammation of the intestine can induce cancer; a high-fat and high-protein diet causes increased bile acid secretion, which is decomposed into unsaturated polycyclic hydrocarbons by anaerobic bacteria in the intestine, which can also cause cancer.

Bowel cancer symptoms:

The clinical features of early colorectal cancer are mainly blood in the stool and changes in bowel habits. When the cancer is confined to the rectal mucosa, blood in the stool is the only early symptom in 85% of cases, but unfortunately it is often not taken seriously by patients. During the rectal examination, a mass can often be felt. In addition to the common systemic symptoms such as loss of appetite, weight loss, and anemia, patients with mid- and late-stage colorectal cancer also have symptoms of local irritation of the cancer, such as increased bowel movements, incomplete bowel movements, frequent bowel movements, and tenesmus. The enlargement of the cancer can cause narrowing of the intestinal cavity and signs of intestinal obstruction.

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

Intestinal cancer is easily misdiagnosed. In the early stages, when the frequency of bowel movements increases and the stool contains mucus, pus and blood, it is easy to be misdiagnosed as dysentery, enteritis or hemorrhoids, thus losing the opportunity for early radical treatment and resection.

The above is a brief introduction to colorectal cancer. For people who are related to the pathogenic factors of colorectal cancer, it is recommended to take preventive measures against colorectal cancer and receive specific treatment according to the doctor's instructions. I hope that patients can recover soon! If you have other questions about colorectal cancer, please consult our experts online or call for consultation.
