When should I get a colon cancer screening?


Colorectal cancer ranks second in mortality from malignant neoplasms. Colon cancer develops from colon polyps. In some cases, it occurs in patients with inflammatory bowel diseases. Colon cancer screenings allow you to detect the illness in the early stages when there are no symptoms. That can increase the chances of successful treatment.

What is a colon cancer screening?

Colorectal cancer diagnosis is a set of measures for the early detection of rectal tumors. The examination shows whether the patient is at risk and whether he needs to undergo in-depth studies or whether it is possible not to do this for some time.

Colon cancer screening: what do I need to know?

Imagine that you don't have a family history of colon cancer and want to stop it from happening. You are recommended to undergo a colonoscopy between 50 and 60.

Another screening method may be an annual stool test for hidden blood, starting from 50 when performing a colonoscopy with positive test results.

You must conduct a regular colonoscopy if you have several blood relatives who have had colon cancer at a young age.

Who needs colon screening test: risk factors

Age is the leading risk factor for developing colorectal cancer in formally healthy people. Following the recommendations of the American Cancer Society, regular CRC screening should begin at the age of 45-50 years. Some people under 45 are also recommended to undergo rectal cancer screening. For example, if:

  • there are inflammatory bowel diseases such as ulcerative colitis;
  • one of the relatives had colorectal polyps;
  • there is a genetic syndrome such as familial adenomatous polyposis or hereditary colorectal cancer.

Risk factors for colon cancer:

  • lack of regular physical activity;
  • a diet low in fiber;
  • overweight;
  • alcohol and tobacco consumption.

How the patients are screened?

A special colon cancer screening test can be used for early detection of a tumor, which recognizes an invisible admixture of blood in the stool. The illness can be suspected when the bowel changes (constipation, diarrhea, alternation of constipation with diarrhea, rumbling, and bloating), bleeding from the rectum, abdominal pain, weight loss, anemia, and changing the size or shape of feces. Most of the time, these signs show up when the tumor is already far along.

Options for colon cancer screening also depend on age and gender:

  • Sigmoidoscopy. Examine the rectum and sigmoid intestine with a sigmoidoscope - a flexible tube with a lens, flashlight, and tissue removal tool. This instrument is injected through the anus into the intestine. The air is injected to extend it so the doctor can see the organ's surface.
  • Blood test for colon cancer. Tumor cells produce cancer markers (proteins present in the blood of cancer patients) into the blood from the moment the neoplasm occurs. Examination of the cancer marker level allows you to suspect the disease in the early stages before the onset of symptoms.
  • Colonoscopy screening. A method for visualizing a large area of the colon. It is recommended for men over 50 and women over 55.
  • Rectoromanoscopy. Comparative studies on large population groups have shown that a regular colon test can reduce morbidity and mortality after 50 years (from 55 to 64). The study covers only the rectum. In some cases, sections of the sigmoid are examined. It is carried out without using a camera.
  • Stool test for colon cancer. Determination of hidden blood in feces. Men and women over 45 can take a stool test every year and every two years from age 55.
  • CT colonoscopy. With the help of a CT scanner, many pictures of the colon are taken, which are then collected into a detailed image of it. As with standard options for colon cancer screening, it is necessary to clean the colon thoroughly.

Doctors use a double contrast barium enema for people who can't have a standard colonoscopy type. The patient is given an enema with a barium solution and an injection during the test. Pictures of the colon and rectum are then taken. Barium helps the pictures show the shape of the colon and rectum.

As a rule, the diagnosis is usually confirmed by colonoscopy – a test of the internal lumen of the colon. So, what a screening colonoscopy is?

Colonoscopy: how do they do?

It is a modern diagnostic procedure using a special probe. The colon is examined using a colonoscope, a flexible tube with a lens, a flashlight, and a tissue removal tool. The probe is inserted through the rectum. It is soft and bends easily, so it gently moves without pain.

Colorectal cancer screening involves thoroughly cleansing the entire colon before the examination. A person must follow a specific diet and take measures to cleanse the intestines. Vegetables, nuts, meat, fruits, pastries, and cereals are removed from the menu. Twenty hours before the procedure, you can drink only water and weakly brewed tea.

Best Countries for check for colon cancer

Hospitals abroad have a very developed screening system. Germany, Israel, Spain, Turkey, and Lithuania are the best countries for the colon exam. So why do patients choose hospitals in these countries? There are some advantages:

  • high-level professionals;
  • lower cost of colon cancer tests than in clinics in the USA or Canada;
  • individual approach to each patient;
  • modern equipment;
  • application of innovative technologies (capsule endoscopy; virtual colonoscopy);
  • doctor's recommendations.
