Large bowel cancer is among the first 5 most common cancer according to the statistics of the Ministry of Health. A significant proportion of bowel cancer patients are in their 50s, and in recent years, they can be seen in younger age individuals for various reasons.
Bowel cancer is called rectum and colon cancer.
Who is at risk for large bowel cancer?
People with a family history of large bowel cancer have a higher risk of developing the disease than others and may be at a younger age.
Changes in genes increase the risk of cancer.
Previous cancer diseases carry the risk of being re-migrated.
Although polyps in the large intestine are benign, they are at risk of cancer. Therefore, it should be removed and checked at regular intervals.
Early diagnosis is very important.
Patients with ulcerative colitis and crown disease (inflammatory bowel disease) are at the risk of cancer.
Nutrition is extremely important. People who have a nutritional program that is weak in terms of fruits and vegetables, calcium, folate, and fiber, and which have an intensive diet in terms of animal fat and food, are at greater risk of developing colon cancer.
Cigarette smoking, as in all types of cancer, also triggers large bowel cancer and should be avoided.
What are the symptoms of large bowel cancer?
Changes in intestinal habits (diarrhea, constipation),
Thinner stools than usual,
Blood in the stool,
Feeling of cramping or bloating,
Unexplained weight loss,
Continuous fatigue may be symptoms of colon cancer such as nausea and vomiting.
When these findings are encountered, it is important to consult a doctor for early diagnosis. As a result of late diagnosis, cancerous cells can reach different sizes and make treatment difficult.
What are the methods used to diagnose large bowel cancer?
Finger Examination of the Rectum:
It is a manual method. After resting the patient’s complaint, if the suspected area is rectum, a finger examination procedure is performed. If any finding is found, further examinations are performed.
Colonoscopy is the method of imaging the entire wall of the colon. If polyps are detected by this procedure, they are removed and our patients are checked and followed up with the same procedure.
Today, this technique is only used to clarify the diagnosis of very early stage rectal tumors. The rectum and surrounding tissues are displayed with the help of a computer that transforms the reflection of sound waves into images. In this way, the tumor will be informed about the depth of the rectum, lymph nodes and its spread to nearby tissues.
Computed tomography (CT):
Computerized tomography technology used for systemic staging is used to diagnose liver and lung metastases.
