    Large Intestine Cancer

    What is Large Intestine (Colorectal) Cancer?

    The last part of our digestive tract is the large intestine, which begins with the end of the small intestine. The large intestine consists of two parts called colon and rectum. The part of the large intestine that starts from the junction with the small intestine is called the colon. In the location close to the anus, the last part of the large intestine is the rectum, which serves as storage. Malignant tumors originating from the large intestines are called colon cancers. We examine bowel cancers under the title of colorectal cancer. Colon cancer is a serious health problem. Nowadays, it is seen at a high rate in both genders. Knowing that colon cancer is a preventable cancer and the importance of screening methods should not be forgotten.

    Colon Cancer in Numbers

    Colon cancer is an important health problem in the world and in our country. When we look at the Ministry of Health data, it is the 3rd most common type of cancer in both genders in terms of frequency. Unfortunately, colorectal cancer is the second most common cause of death in our country. In our country, 15000 new cases are detected every year. We lose approximately 7200 citizens annually to colorectal cancer.

    Approximately 80-85% of all colorectal cancers occur in people over the age of 50. However, it should not be forgotten that 15-20% of the patients are young patients under the age of 50. In recent years, we have seen that the numbers, especially in the young patient group, have increased statistically. The frequency of rectal cancer is increasing, especially in the young patient group. All colon cancers, that is; 70% of colorectal cancers are located in the colon and 30% are located in the rectum. This ratio gives very similar figures for both genders. When we look at the location of colon cancers, we see that left colon tumors are the most common, and this rate is approximately 30%. Approximately 60% of colorectal cancers appear in the first 50-60 cm of the anus.

    The rectum, which is approximately 15-18 cm long, appears as three 6 cm sections. The first 6 cm of the anal entrance is considered the lower rectum, the 6-12 cm area is considered the middle rectum, and the location 12 cm above is considered the upper rectum.

    We said that 30% of all colon cancers are in the rectum. When this ratio is divided, 10% is seen in each section, that is, the upper 33%, the middle 33%, the lower 33%. 10% of all chlorectal cancers are located in the lower rectum, 10% in the middle rectum, and 10% in the lower rectum.
