Colon Tumors
Benign or malignant tumors arising in the colon, including polyps and colon cancer.
Overview
Colon tumors may arise from benign polyps that can develop into malignant tumors over time if not detected and treated early, which is why regular screening (colonoscopy) is an important tool for early detection and prevention.
Treatment depends on the tumor's type, stage, and location, and may involve surgery, chemotherapy, and sometimes radiation therapy, as part of a plan developed by a multidisciplinary medical team.
Common Symptoms
- A change in bowel habits (persistent diarrhea or constipation)
- Blood in the stool or rectal bleeding
- Abdominal pain or cramping
- Unexplained weight loss
- Unexplained anemia
- A persistent feeling of incomplete bowel emptying
Causes & Risk Factors
- Advancing age
- Family history of colorectal cancer or polyps
- Chronic inflammatory bowel disease
- A low-fiber, high-fat diet
- Smoking and alcohol consumption
- Physical inactivity and obesity
How It Is Diagnosed
- Colonoscopy with biopsy when a suspicious mass or polyp is found
- CT imaging to assess the extent of tumor spread
- Blood tests including tumor markers
- Discussion of the case in a multidisciplinary tumor board to determine disease stage
When to See a Doctor
- When a change in bowel habits persists for more than a few weeks
- When noticing blood in the stool
- With unexplained weight loss accompanied by digestive symptoms
- Upon reaching the recommended screening age or with a relevant family history
Available Treatment Options
- Polyp removal via colonoscopy in very early stages
- Surgery to remove the affected segment of the colon
- Chemotherapy, before or after surgery depending on disease stage
- Radiation therapy in selected cases
When Surgery May Be Considered
- When a tumor cannot be removed by colonoscopy alone
- As part of an integrated treatment plan following multidisciplinary evaluation
- In cases of bowel obstruction caused by the tumor
General Recovery Information
Recovery time varies depending on the extent of surgery and the technique used (open or laparoscopic)
Some patients may need an adjustment period for digestive changes after removal of part of the colon
Regular follow-up after surgery is important to monitor for any signs of tumor recurrence
Potential Complications
- Bleeding or infection at the surgical site
- Anastomotic leak (leak at the bowel reconnection site) in rare cases
- Changes in bowel habits after surgery
When Urgent Medical Evaluation Is Needed
- Heavy rectal bleeding
- Sudden, severe abdominal pain with distension
- Complete absence of bowel movements and gas
Frequently Asked Questions
Do all colon polyps turn into cancer?
No, most polyps are benign, but certain types may develop into cancer over time if left untreated, which is why removal and periodic follow-up are recommended.
