How to prevent colorectal cancer? Increase calcium intake

Colorectal cancer is an adenocarcinoma that occurs in the large intestine and is a common malignant tumor in the intestine. People still cannot fully explain why colon cancer occurs, but its occurrence is closely related to a high-fat, low-fiber diet. About 40% of colorectal cancer occurs in the rectum and sigmoid colon, and the tumor can metastasize to other parts of the body. Polyps in the large intestine may turn into cancerous tumors. Colorectal cancer develops slowly and can be cured if it is discovered and treated early.

How to prevent colorectal cancer

Medical research has found that taking multivitamins and folic acid every day and increasing calcium intake can reduce the risk of cancer.

Taking aspirin and antipyretics for arthritis may reduce the risk of colorectal cancer.

If someone in your family has colon polyps, ulcerative colitis or colorectal cancer, then your risk of cancer is higher than normal. We recommend that you go to the hospital for regular check-ups and actively seek early treatment if any abnormality is found.

Choose a low-fat, high-fiber diet. Eating 5 to 6 servings of fruit and high-fiber cereals a day can reduce the risk of colorectal cancer.

What are the early symptoms of colorectal cancer?

When colorectal cancer first begins to develop, people may have no symptoms or only a little discomfort. People should start regular colon examinations at the age of 50. If you find that your bowel habits have changed, such as alternating constipation and diarrhea, and blood in the stool, for more than 10 days, you should go to the hospital for a check-up immediately. Colorectal cancer can be cured in the early stages (pre-stage 3).

Diagnosis of colorectal cancer. If a person has the following symptoms, we highly suspect that he has colorectal cancer.

Gastrointestinal dysfunction, poor appetite, abdominal discomfort, fullness, constipation, diarrhea, or alternating diarrhea and constipation.

Symptoms of intestinal obstruction mainly include abdominal pain, constipation, abdominal distension, vomiting, and hyperperistalsis.

Bloody stools are the main symptom of colon cancer and the first and most common symptom of rectal cancer. Because the location of the cancer is different, the amount of bleeding and the manifestations vary from patient to patient. Long-term bleeding can cause secondary anemia in patients.

If you feel a mass in the abdomen, it is usually cancer itself, but it may also be caused by intra-abdominal metastasis or inflammatory infiltration. If you feel a mass in the abdomen that appears and disappears from time to time, it often indicates incomplete intestinal obstruction.

In terms of systemic symptoms, patients may have varying degrees of anemia, malnutrition, systemic failure, weight loss, and cachexia.

Patients may also have other symptoms, such as cancerous tumors that may rupture and become infected, causing chills and fever. Intestinal perforation may cause diffuse or localized peritonitis. Cancerous tumors that invade the urinary system may cause urinary system symptoms. In the late stages of cancer, patients may experience hepatomegaly, jaundice, ascites, enlarged left supraclavicular lymph nodes, and other symptoms specific to organ metastasis.

Screening for colorectal cancer

A colonoscope is used to view the inside of the colon.

The fecal occult blood test (FOBT) can detect even a small amount of blood in the stool. There are many causes of occult blood, one of which is colorectal cancer.

A routine blood test revealed anemia.

A CT scan showed a mass in the large intestine.
