Understanding Rectal Cancer
Rectal cancer develops in the last several inches of the large intestine, and accurate staging determines the right treatment.
Early-Stage
Small, localized tumors can often be removed with minimally invasive, sphincter-preserving surgery and excellent cure rates.
Locally Advanced
Larger tumors may be treated with a combination of chemotherapy, radiation, and precise robotic surgery.
Precancerous Polyps
Advanced rectal polyps can sometimes be removed before they ever become cancer.
Symptoms and Risk Factors
Warning signs include rectal bleeding, a change in bowel habits, narrow stools, a feeling of incomplete emptying, abdominal discomfort, and unexplained weight loss. Any rectal bleeding should be evaluated promptly rather than assumed to be hemorrhoids.
Risk factors include age over 45, a family or personal history of colorectal cancer or polyps, inflammatory bowel disease, and certain inherited syndromes. Screening colonoscopy catches problems early, when treatment is simplest.
Rectal Cancer Treatment Options
Dr. Barnajian creates an individualized plan that prioritizes cure, preserves function whenever possible, and coordinates with your oncology team.
Robotic Surgery
Minimally invasive, precise removal of the tumor deep in the pelvis, with better visualization and faster recovery.
Sphincter Preservation
Whenever safe, techniques that preserve normal bowel function and avoid a permanent colostomy.
Transanal Surgery
For select early tumors, removal through the anus with no abdominal incision and rapid recovery.
Coordinated Chemoradiation
When needed, surgery is combined with chemotherapy and radiation, all coordinated for the best outcome.
Survivorship Care
Structured follow-up protects your long-term health and catches any recurrence early.
