Catherine Mary Burke Remembered for Advancing Breast Cancer Screening in Manitoba

Catherine Mary Burke faced breast cancer with extraordinary resilience, but her influence extended far beyond her own decade-long struggle. Through persistent advocacy, the Winnipeg mother helped improve access to breast-density information so other women could make more informed decisions about screening.

A Life Defined by Optimism and Determination

Burke died on Nov. 29, 2025, at age 67 after living with breast cancer for more than a decade. Her husband, Patrick Burke, remembered her as someone whose optimism remained unwavering throughout her illness.

“Cathy was born happy,” he said. “She was a glass-half-full person. What a gift this attitude was to me and the boys. She never once said ‘Why me?’ or complained. She was just so happy to be alive.”

Her warmth was evident in everyday interactions, he added.

“If I stood with her in line at Safeway, by the time we got checked out, she’d had multiple conversations. She knew the tellers, the bag boy — she knew them all,” Patrick said, noting that it was nearly impossible to find a photograph of her without a broad smile.

A 43-Year Love Story

The couple met during the summer of 1979 at a hotel in Keewatin, Ont. Their relationship deepened after an unexpected meeting at an airport in August 1980, when Patrick was travelling to Toronto and Cathy was returning to Saskatoon to complete her agricultural degree.

They arranged to meet again in Winnipeg over the Labour Day weekend.

“The rest is history,” Patrick said.

He recalled an early dinner accompanied by a bottle of red wine and Van Morrison’s “Into the Mystic.”

“She said I should play it at her wake as she was going to go first,” he said. “Sadly, she was right, as she was most of the time.”

The couple married in 1982. After honeymooning in Florida, they briefly moved to Toronto during a recession, when Cathy found part-time work as a bank teller. They later returned to Winnipeg and raised three sons: Sean, Timothy and Kerry.

Cathy was a close friend and confidante to her sons, and the family home became a gathering place filled with cooking and baking. She was also an enthusiastic sports fan, a devoted caregiver and a lover of nature, wildlife and gardening. She spoke with her parents every day.

A Missed Tumour Changed Her Life

Burke was diagnosed with breast cancer in 2016. A review found that a tumour had appeared on a mammogram two years earlier but had been missed. The head of the breast clinic personally called her to apologize.

“It didn’t make her bitter,” Patrick said. “She was determined to make it better for others. When she saw something wrong, she was determined to right it.”

Her experience drew attention to the limited information Manitoba patients received about breast density, which can make cancer more difficult to detect through a standard mammogram and may increase breast cancer risk.

“Cathy’s cancer was estrogen-driven. There were lots of things she could have done. They didn’t tell her. Forty-two per cent of women over the age of 40 have dense breasts,” Patrick said.

Advocacy for Better Breast-Cancer Screening

Over nearly a decade, Burke underwent four major surgeries, seven chemotherapy regimens, 50 radiation treatments and other aggressive therapies. She also took numerous medications that caused a wide range of side effects.

“She endured it all with grace and fortitude,” Patrick said.

Despite the demands of treatment, Burke became an advocate with Dense Breasts Canada. She worked with other advocates in Manitoba and attended meetings at CancerCare Manitoba to push for greater awareness and improved screening policies.

“She had breast cancer for 16 per cent of her life,” Patrick said. “No one told her about the risks or offered her access to additional screening. She turned outward to help others.”

Her advocacy helped make breast-density information available to Manitoba women, giving patients a better opportunity to discuss their risks and possible additional screening with health-care providers.

“Now women in Manitoba receive essential information and have a chance to be proactive,” Patrick said. “Other provinces were encouraged to follow. She stepped up for better policies. Her legacy in the breast screening is a significant one.”

Burke’s life was marked by family, optimism and an enduring concern for others. Even while facing years of difficult treatment, she worked to ensure that future patients would have access to information she never received—leaving a lasting contribution to breast cancer awareness and screening in Manitoba.
