Being afraid to go to the hospital in Turkey for fear of contracting the corona virus, which has deeply affected our country for about a year, also prevents the chances of early diagnosis of colon cancer. A gastroenterologist who gave information about Colon Cancer Awareness Month in March, Professor Dr. NT listed 6 correctly known misinformation about colon cancer.

Gastroenterology Specialist Prof. Dr. “In March March Colon Cancer Awareness Month and March 3 World Colon Cancer Awareness Day, NT said; while emphasizing that colon cancer can be largely prevented by colonoscopy, he says that some of the right known mistakes about colon cancer delay the diagnosis and treatment of the disease.”

Prof. Dr. NT told 6 mistakes that are known to be true in society about colon cancer, made important warnings and suggestions.

Colon cancer, which ranks third in cancer deaths in both women and men in our country, is a type of cancer that can be prevented if the rules are followed and its treatment is laughable when diagnosed early thanks to colonoscopy. Because 98 percent of the cancer develops on the basis of polyps, and colonoscopy prevents the removal of polyps. However, being afraid to go to hospitals and postponing colonoscopy, especially during the pandemic, can lead to an advanced diagnosis of colon cancer!

Prof. Dr. added “375 thousand people every year in Europe from the light, the dust has received a diagnosis of colon cancer and 170 thousand people had died from the disease, noting that “50 years and older cancer screening programme need to be included in healthy people, and those who have check to see that the treatment of colon cancer colonoscopy, a significant portion of Covid-19 due to fear of contamination last year, the hospital did not. This, in turn, has increased the likelihood that we will encounter advanced colon cancer, according to our experience and some publications. A study conducted at the University of Bologna in Italy found that 4-6 months of colon cancer screening increases advanced colon cancer by 3 per cent, while a delay of more than 12 months increases this rate to 7 per cent. However, it is unknown when the pandemic will leave us, and screening programs should certainly not be disrupted by taking very good measures against Corona.”he says.


A professor who said that there are some false beliefs about colon cancer in society Dr. NT emphasizes that these false beliefs prevent the possibility of early detection and cause the disease to reach an advanced stage. Prof. Dr. NT explained these false beliefs and truths in society as follows;

1. Blood coming from breech indicates hemorrhoid disease, should not be underestimated: wrong!

In fact: most patients are afraid that a bad disease will occur with “I have hemorrhoids, I think it is the cause of bleeding.”he does not refer to the doctor with his rhetoric, he follows the advice of the neighbor and turns to alternative medicine. Sometimes, the doctor attributes the bleeding to this condition, especially if there is a hemorrhoid or fissure (crack) during the examination, especially in young and chronic constipation patients. However, blood coming from the breech can be a harbinger of cancer or a large polyp. A detailed examination is required.

2. This disease is genetic, there is no cancer in my family: wrong!

In fact: 15 percent of cancers occur on a genetic basis. Having colon cancer near the first degree of a person or having familial colon polyposis increases the risk of developing cancer. But people who have never had cancer in their family can also develop colon cancer. Recent publications also recommend genetic screening of tumor tissue in non-familial colon cancers.

3. Long-term constipation then leads to cancer: wrong!

In fact: there is no information that chronic constipation or sensitive bowel syndrome leads to colon cancer. But when colon cancer or a large polyp is large enough to narrow the intestinal cavity, constipation, intestinal obstruction, or bleeding from the breech can occur. People whose bowel habits change in this direction should definitely see a gastroenterologist.

4. Colonoscopy is a very difficult and painful procedure, it can even be fatal! Wrong!

In fact: colonoscopy is a procedure with a fairly low risk in specialist hands. Bowel puncture or bleeding during colonoscopy is less than 1 in 1000. Before colonoscopy, the patient is evaluated for concomitant diseases, their medications are adjusted. (For example, antibiotics, blood thinners, anti-diabetics, etc. in those whose heart valve has been replaced, etc.), bowel cleansing is performed according to their known diseases or body structure, since the procedure is performed under deep sedation (sleep), the patient does not feel pain, and general anesthesia is not required, except in special cases in the procedure.

5. Why should I have a colonoscopy when I have no complaints? Wrong!

In fact: a person’s lifetime risk of developing colon cancer is 6 percent, a probability that will not be underestimated at all. In other words, 1 out of every 18 people can develop colon cancer. Colon polyps and colon cancer are known to be more common in obese people and smokers, those who regularly drink alcohol, those who eat processed food, those who have colon cancer in their family, and those who do not exercise. However, with colonoscopy, the risk of death from colon cancer decreases by 45 percent.

6. There are drugs that prevent colon cancer! Wrong!

Truth: although much work has been done on this issue, there is no clear result. Some studies of non-steroidal anti-inflammatory drugs, calcium, magnesium, folic acid, B6 and B12, vitamin D, statins and cancer preventive effect of aspirin mentions, though this effect was verified in a large series. It is said that perhaps marginal good can be achieved in those who use aspirin for other purposes. There’s a lot of distance to be taken about this. It is best to eat a healthy and fiber-rich diet, exercise, stay away from smoking and alcohol, and not gain weight.


Colon cancer develops 98 percent on the polyp floor, and cancer in polyps above 15 mm in diameter is 1.5 times more than in those below 15 mm. A professor who said that taking polyps with colonoscopy prevents cancer Dr. NT says that colon cancer screening programs based on various protocols are currently conducted in almost all European countries, a study conducted in 16 European countries between 2000-2016 reported that the frequency of colorectal cancer significantly decreased, especially in countries that started the screening program early. Gastroenterology Specialist Prof. Dr. NT describes how colon cancer screening is performed as follows: “usually, in many countries, the screening method is used to look at Hidden blood in the stool every year or every two years. Some countries accept colonoscopy as the gold standard, which is a more sensitive but more costly method and also allows the removal of polyps with precancerous lesions. With today’s technology, early colon cancers and polyps can be better recognized with artificial intelligence-based imaging systems. Although colonoscopy is the gold standard for detecting polyps, the success of the procedure; the experience of the person performing the colonoscopy and the quality standards of the procedure are determined.”


A Turkish professor who stressed that no screening program and controls should be disrupted, thinking that the covid-19 pandemic can continue for a long time Dr. NT said, “For this purpose, compliance with the necessary precautions (mask, distance, cleaning) in pandemic conditions and taking measures such as the Covid-19 vaccine; a secret blood test in the stool or, preferably, a colonoscopy seems to be the most effective and rational way to protect against colon cancer. So who should be screened?

Generally, the screening age is considered 50 years for people at average risk. Screening is performed by looking at Hidden blood in the stool every 2 years by a sensitive method and applying a colonoscopy to those whose test is positive. According to the findings, colonoscopy is repeated 1-3-5, or 10 years later, if everything is normal. Although the age of termination of the scan is determined to be 75, this period can be extended according to the person.

After early colon cancer has increased in recent years, it is recommended to start screening at the age of 45 or even 40.

It is necessary to start screening in Turkish hospitals at an earlier age for people with colon cancer near the first degree or one of the familial polyposis syndromes.
