Impact of Colorectal Cancer on Women's Sexual Health Revealed by New Study

A comprehensive study led by the University of British Columbia has highlighted a concerning long-term consequence of colorectal cancer that has often been overlooked: its persistent impact on women’s sexual health. The research analyzed health data from over 25,000 women in British Columbia diagnosed with colorectal cancer between 1985 and 2017, comparing their experiences to those of women without cancer. The findings indicate that treatments such as surgery, chemotherapy, and radiation can lead to significant and lasting sexual health issues. Notably, women who underwent treatment had a 67% higher risk of experiencing dyspareunia, a painful condition during sex, which can severely affect quality of life. This risk was even higher—up to 90%—for women diagnosed before age 40.

The study also found that survivors are more than three times as likely to develop pelvic inflammatory disease and nearly twice as likely to be diagnosed with endometriosis. For younger women, the risk of premature ovarian failure or early menopause was 75% higher compared to women without cancer.

Published in the Journal of the National Cancer Institute, the research emphasizes that sexual health issues post-treatment are common, but often only diagnosed long after cancer therapy concludes. Dr. Mary De Vera, senior author and an associate professor at UBC, stressed the importance of integrating sexual health support into cancer survivorship care. As a colorectal cancer survivor herself, Dr. De Vera recognizes the difficulties faced and advocates for increased awareness, early intervention, and better support systems for women.

Colorectal cancer remains one of Canada's most prevalent cancers, with approximately 10,500 new cases expected in 2023. While traditionally viewed as a disease affecting older men, incidence rates are rising among women and younger populations. Dr. Lori Brotto, a women’s sexual health specialist at UBC and co-author of the study, highlighted the critical gap in standard cancer care regarding sexual health. She urged healthcare providers to receive training to better identify and support sexual health issues among survivors.

Overall, the study underscores the urgent need for improved education, open discussions, and comprehensive care approaches to address these often-neglected aspects of health in women who have survived colorectal cancer. Recognizing and managing these issues is essential for enhancing survivors' quality of life and ensuring more holistic cancer care.
