The 3rd most common type of cancer in men and women!


Prof. Dr. Birol Özer, in his written statement on the occasion of “Colorectal (Colon) Cancer Awareness Month”, stated that colon cancer is a life-threatening disease that develops from the inner surface of the large intestine.

Stating that 19 million new cancer diagnoses and 10 million cancer-related deaths occurred in the world in 2020, Özer said that 2 million of them are colon cancer, 900 thousand deaths are due to colon cancer, and it is estimated that 2.5 million new cases will be diagnosed in 2035. noted.

Expressing that there has been an increase in colon cancer, especially in the left side and rectum, under the age of 50, Özer stated that the reason was the increasing obesity and the widespread use of western type diet habits in the 1990s.

Prof. Dr. Özer said, “Colon cancer is the 3rd most common type of cancer in men and women. Approximately one third of the cases are located in the rectum. In our country, 233 thousand new cancer diagnoses and 126 thousand cancer-related deaths were reported in 2020. In colon cancer, 21 thousand new diagnoses, 10 a thousand deaths have occurred. ” made its evaluation.

Ozer is a year for over a new type of affect also Turkey coronavirus (Kovid-19) arrest, fearing the hospital to go to the prohibition because of screening programs ignore the poor compliance of the symptoms and the bride, that prevents the chances of early diagnosis of colon cancer was noticed.

Pointing out that it is estimated that delaying screening for 6 months due to the Kovid-19 epidemic in the USA, 2 thousand 800 colon cancer and 22 thousand high-grade pre-cancer formation is estimated to be late diagnosis, Özer said that this delay will cause an increase of 6.5 percent in 6 months of death. He emphasized that it was foreseen.

“Men are 25 percent more at risk than women”

Özer stated that colon cancer is seen most frequently in Australia, New Zealand, Europe, North America and least in Africa and Southeast Asia, and listed the risk factors as follows:

“The lifetime risk of colon cancer in individuals at average risk is 4%, and the risk is 25% higher in men than in women. Genetic predisposition, age, personal and family history of colon cancer, inflammatory bowel disease, abdominal radiation therapy are the main risk factors. Lack of physical activity. Unhealthy diet, smoking, diabetes, obesity, as well as low socioeconomic status are also factors that increase the risk. The risk increases 1.23 times in weight gain in early adult and middle age. It is acceptable to consume 1 or 2 times a week within a balanced diet. Vegetables, whole wheat, foods containing folate and less calories should be consumed, excessive alcohol consumption should be avoided. “

Prof. Dr. Özer pointed out that colon cancer is one of the leading preventable cancers and deaths tend to decrease with screening programs, early diagnosis and effective treatment in recent years, “70% of sporadic (incidental) colon cancers are adenomatous polyps (moles that develop in the intestine), 30%. It develops from sessile serrated lesions. Early detection and removal by endoscopy reduces cancer and deaths. Colonoscopy reduces cancer incidence by 69 percent and deaths by 68 percent. ” found the assessment.

“Colon cancer screening should be done between the ages of 50-75”

Özer stated that colonoscopy is the process of imaging the inside of the large intestines with a camera with a tip, and stated that the rate of colon cancer detection in the patient with normal colonoscopy was 1 in 3 thousand 174 patients.

Expressing that colon cancer screening should be done between the ages of 50-75, Özer said:

“The benefit of screening may be limited as the life expectancy rate decreases over the age of 75, as the benefit of polypectomy (removal of the polyp) will occur after 7-8 years in those who have polyps detected in colonoscopy. Moreover, elderly individuals are more sensitive to the risks associated with screening. Screening can be performed according to health status, but screening is not recommended because life expectancy decreases over 86 years of age. If there is a family history of colon cancer, colonoscopy should be performed before the age of 40 or 10 years before the age of first degree relatives. This risk is more pronounced in younger age group. Control colonoscopy should be done every 5 years. Stool blood test should be done once a year, colonoscopy should be done once in 10 years. “

Prof. Dr. Özer stated that there is no drug with proven effectiveness in preventing the development of colon cancer, but if there is a risk of developing cardiovascular disease in individuals over the age of 50, aspirin use for more than 10 years may be beneficial.
