Beware of Colorectal Cancer

Ondokuz Mayıs University (OMU) Faculty of Medicine, Department of Surgical Medical Sciences, Division of General Surgery faculty member Assoc. Prof. Dr. İsmail Alper Tarım warned the public about colorectal cancer as part of Colorectal Cancer Awareness Month.

The Third Most Common Type of Cancer Worldwide

In his statement, Assoc. Prof. Dr. Tarım emphasized the prevalence of colorectal cancers, stating:

“Colorectal cancers, or large intestine cancers, are among the most commonly seen cancer types both in our country and worldwide. It is the third most frequently diagnosed cancer globally. The majority of colorectal cancer patients are over the age of 50. Unfortunately, 70% of patients seek medical attention at an advanced stage, making treatment more challenging for both the patient and the physician due to delayed diagnosis. However, if detected early, colorectal cancer is highly treatable. Identifying precancerous colon pathologies at an early stage through simple treatment methods can significantly reduce both cancer incidence and cancer-related deaths.”

Regular Screening Is Essential

Assoc. Prof. Dr. Tarım highlighted the importance of routine screenings, stating:

“Since colorectal cancer screenings are proven to enhance quality of life and increase life expectancy, the World Health Organization (WHO) includes them among the recommended cancer screening programs. Colorectal cancer screenings are performed through fecal occult blood tests and colonoscopy. For individuals over 50, it is crucial to undergo a fecal occult blood test every two years and a colonoscopy every ten years for early detection of colorectal cancer.”

Individuals Aged 50 and Above Should Be Cautious

Emphasizing the importance of awareness in cancer screenings, Assoc. Prof. Dr. Tarım noted:

“March has been recognized as Colorectal Cancer Awareness Month in our country and globally. Throughout this period, various activities aim to raise awareness on this issue. Screening tests are a must. I strongly recommend that individuals aged 50 and above visit their family physicians and have colorectal cancer screenings done as part of their routine health check-ups.”

The Importance of Nutrition

Pointing out the link between diet and cancer risk, Assoc. Prof. Dr. Tarım concluded:

“Low fiber intake, smoking, alcohol consumption, and excessive consumption of processed foods—especially highly processed meats like sausages and salami, as well as red meat such as beef, lamb, and liver—have contributed to a rise in colorectal cancer cases, even among younger individuals.

The most alarming symptoms include the presence of blood in stool and sudden bowel irregularities. Regardless of age, individuals experiencing such symptoms must consult a physician and undergo necessary screenings.”
