Catherine O'Hara's Rectal Cancer Diagnosis Raises Awareness

Why this matters: Colorectal cancer is a significant health concern, but early detection and treatment can greatly improve outcomes. Increased awareness and open conversations can help reduce stigma and encourage people to get screened.

Background

Catherine O'Hara, the Emmy-winning actress, passed away at the age of 71. A Los Angeles County death certificate listed a pulmonary embolism as the immediate cause of death, with rectal cancer as an underlying cause. This has led to increased awareness of colorectal cancer and the importance of early detection.

Colorectal Cancer Statistics

Colorectal Cancer Canada reports that colorectal cancer is the fourth most frequently diagnosed cancer in Canada. While most cases occur in adults 50 or older, there has been a rise in incidence among younger adults since the early 2000s. BC Cancer states that in 2026, an estimated 3,515 people in B.C. will be newly diagnosed with colorectal cancer. The federal government estimates that one in 14 men and one in 18 women will be diagnosed with colorectal cancer in their lifetime.

Detection and Screening

Health Canada reports that 47 per cent of colorectal cancer cases are diagnosed early in their development, at Stage 1 and 2. The Canadian Cancer Society notes that in its early stages, colorectal cancer may not cause any signs or symptoms. However, as a tumour grows, symptoms can include bleeding from the rectum, fatigue and weakness, weight loss, or breathing problems.

BC Cancer recommends talking to a health-care provider if you experience any of these symptoms. Health Canada recommends screening for colorectal cancer for average-risk adults aged 50 to 74 years.

Dr. Ted McAlister recommends a fecal immunochemical test every two years to test stool for hidden blood. If the test is positive, a colonoscopy is performed to check for abnormalities. Early colorectal cancer is usually treated with surgery and is often cured. More advanced cases may require chemotherapy and radiation therapy.

Colorectal Cancer Canada says you may be at a higher risk of developing colorectal cancer if you have:
