Rectal Tumors
Tumors arising in the rectum, the final segment of the large bowel, requiring careful evaluation and treatment planning due to proximity to the sphincter muscles controlling bowel continence.
Overview
Rectal tumors share many risk factors and symptoms with colon tumors, but require specialized treatment planning due to their proximity to the sphincter muscles and neighboring pelvic organs.
Treatment often involves coordination between surgery, chemotherapy, and radiation therapy, and chemoradiation may be given before surgery in selected cases to shrink the tumor.
Common Symptoms
- Rectal bleeding or blood in the stool
- Changes in stool consistency or frequency
- A feeling of incomplete rectal emptying
- Pain or discomfort in the pelvic or rectal area
- Unexplained weight loss
Causes & Risk Factors
- Advancing age
- Family history of colorectal cancer
- Chronic inflammatory bowel disease
- A low-fiber, high-fat diet
- Smoking
How It Is Diagnosed
- Rectal or colon endoscopy with biopsy
- Pelvic MRI to precisely assess the tumor's location and extent
- CT imaging to assess spread beyond the pelvis
- Discussion of the case in a multidisciplinary tumor board to determine the treatment plan
When to See a Doctor
- When noticing recurring rectal bleeding
- With a persistent change in bowel habits
- When feeling pain or a mass in the rectal area
Available Treatment Options
- Combined chemoradiation before surgery in selected cases
- Surgery to remove the tumor, preserving sphincter function whenever possible
- Chemotherapy after surgery depending on pathology results
When Surgery May Be Considered
- As a core part of the treatment plan after completing neoadjuvant chemoradiation when indicated
- After careful assessment of the tumor's location and the feasibility of preserving normal bowel continence
General Recovery Information
Some cases may require a temporary or permanent stoma depending on the tumor's location and extent, which is discussed in detail with the patient before surgery
Multidisciplinary follow-up after surgery is important to assess recovery and the need for further treatment
Potential Complications
- Bleeding or infection at the surgical site
- Anastomotic leak
- Changes in bowel continence or urinary and sexual function in rare cases
When Urgent Medical Evaluation Is Needed
- Heavy, persistent rectal bleeding
- Sudden, severe pelvic pain
- Acute bowel obstruction
Frequently Asked Questions
Do all rectal tumors require a permanent stoma?
No, the need for a temporary or permanent stoma depends on the tumor's location, size, and proximity to the sphincter muscles, and is determined after careful case-by-case evaluation.
