Five Breakthroughs in Women's Cancer Care That Are Changing Lives—Here's What's New

Researchers in British Columbia have developed five groundbreaking approaches to women's cancers that are now transforming care worldwide. These innovations span early detection, genetic testing, and prevention strategies—offering hope to the one in eight women who will face breast cancer in their lifetime, plus those at risk for cervical, ovarian, and endometrial cancers. The advances range from a home-based cervical cancer screening option to a surgical technique that can reduce ovarian cancer risk by 80%.

How Are Doctors Improving Breast Cancer Detection and Survival?

Breast cancer survival rates in British Columbia have reached 92% for early-stage cases, thanks to decades of innovation. BC Cancer researchers have fundamentally reshaped how the world understands and treats breast cancer. In 1988, BC Cancer established Canada's first screening mammography program, which reduced breast cancer incidence in the province by 25%. More recently, researchers reclassified breast cancer into 10 distinct subtypes rather than treating it as a single disease, allowing for more personalized treatment approaches.

A recent discovery by BC Cancer's Dr. Sam Aparicio and his team uncovered cancer-like mutations in healthy breast cells. This finding could help pinpoint the early genetic origins of breast cancer, potentially leading to improved detection and prevention strategies before cancer develops. Additionally, donor-supported research initiatives are expanding genetic testing to all breast cancer patients under 60 to better identify BRCA gene mutations—genetic changes linked to significantly higher breast and ovarian cancer risk.

What's Changing in Cervical Cancer Screening?

Cervical cancer is on the cusp of elimination in British Columbia, thanks to a pioneering self-screening option launched in 2024. BC Cancer established the world's first cervical screening program in 1955, which has led to a 61% decrease in cervical cancer incidence in the province. Now, the organization is taking screening a step further with a home-based self-swab kit that screens for human papillomavirus (HPV), the virus responsible for 99% of cervical cancers.

HPV testing is more accurate and more sensitive than traditional Pap tests and can be completed at home or at a healthcare provider's office. From February 2024 to November 2025, BC Cancer sent 240,000 self-screening kits to eligible people in the province. Notably, 34% of these kits were requested by people who had never been screened for cervical cancer before, suggesting the at-home option is reaching women who previously avoided screening.

Steps to Understanding Your Genetic Cancer Risk

• Genetic Testing Expansion: Donor support is now expanding genetic testing to all breast cancer patients under 60 to identify inherited BRCA mutations that significantly increase breast and ovarian cancer risk.
• Expedited Ovarian Cancer Testing: Genetic testing is being prioritized for women with one or more direct relatives diagnosed with ovarian cancer, allowing families to learn of their inherited risk sooner.
• Hereditary Cancer Program: BC Cancer's Hereditary Cancer Program is making genetic testing more accessible, helping more women in British Columbia understand their personal cancer risk and take preventive action.

How Is Endometrial Cancer Care Being Revolutionized?

All women diagnosed with endometrial cancer in British Columbia now receive consistent, equitable care thanks to a made-in-BC classification tool called ProMisE (Proactive Molecular Risk Classifier for Endometrial Cancer). Developed by BC Cancer's Drs. Jessica McAlpine and Aline Talhouk, ProMisE organizes endometrial cancers into four subtypes based on molecular characteristics rather than appearance under a microscope.

Before ProMisE, endometrial cancer classification relied on how tumors looked microscopically—an approach that worked for ovarian cancer but led to inconsistencies and over- or undertreatment in endometrial cancer patients. Now the standard of care worldwide, ProMisE guides how patients are cared for before and after surgery and informs how much radiation or chemotherapy is needed. Remarkably, the tool even allows some patients to safely avoid treatment altogether. ProMisE also identifies patients at risk of inherited genetic syndromes that increase their likelihood of developing other cancers.

Can Ovarian Cancer Be Prevented Before It Starts?

Women at high risk of ovarian cancer now have a prevention option that can reduce their risk by 80%. After BC Cancer's OVCARE team discovered that ovarian cancer comprises multiple distinct subtypes and that most ovarian cancers originate in the fallopian tubes, Dr. Dianne Miller developed the world's first ovarian cancer prevention strategy: opportunistic salpingectomy (OS). This procedure removes the fallopian tubes—often during other pelvic or abdominal procedures—eliminating the tissues where most ovarian cancers begin.

OS is performed during routine surgeries such as a hysterectomy, making it a practical approach to cancer prevention. In 2022, the OVCARE team received international recognition for pioneering this major breakthrough. The team is now working to increase uptake of OS through patient and physician educational outreach programs. If more women and doctors adopt this approach during routine surgeries, it could prevent thousands of ovarian cancer cases worldwide each year.

Why Do These Advances Matter?

Women's cancers have historically been underfunded and understudied globally. These five British Columbia-led innovations represent a shift toward more personalized, preventive, and equitable cancer care. From expanding genetic testing to launching home-based screening options to developing prevention surgeries, these breakthroughs offer women more choices, better outcomes, and opportunities to stop cancer before it starts. As these advances continue to spread worldwide, they're reshaping how millions of women approach cancer detection and prevention.
