What are Uterine Fibroids?

Uterine fibroids are a common non-cancerous tumour of the uterus. A non-cancerous (benign) tumour is a growth that doesn’t spread (metastasize) to other parts of the body. High levels of the hormones estrogen and progesterone increase their growth, as well as chemicals that mimic female hormones. In most cases, fibroids are extremely small and barely noticeable. They should be monitored as they can expand in size over time and in some cases lead to infertility, chronic pain, and cancer.

Occupational Risks and Fibroids

The Canadian Centre for Occupational Health and Safety (CCOHS) has a web page on reproductive health as it relates to workplace conditions.

Reproductive health issues are usually not work related. However, exposure to metals, solvents, pesticides, radiation, viruses, and extreme stress are all factors that can effect reproductive health. Xenoestrogens are foreign, man-made chemicals that mimic or disrupt natural estrogen and are found in plastics and other everyday substances present in our environment. In some production facilities and business prolonged exposure to chemicals has been linked to fibroid tumors, reproductive issues, endocrine imbalances, and hormone-dependent cancers. Published research such as this has indicated a connection.

In addition to chemical exposure, research has revealed the stress caused by regular night shift work can disrupt the endocrine system and lead to tumor growth and even cancer, especially in women.

• Exposure to industrial solvents, pesticides, and plastics/BPA can interfere with hormone signaling, which is linked to an increased likelihood of developing fibroids. 
• Workplace exposure to heavy metals such as cadmium and lead has been associated with adverse uterine health. [1]
• High-stress occupations and chronic sleep deprivation (e.g., rotating night shifts) can trigger hormonal imbalances and exacerbate the pelvic pain and heavy bleeding associated with fibroids. According to current research published in Biomedical Reports, the International Journal of Environmental Research and Public Health and other sources, night shift work is the leading work-related factor that increases the risk for reproductive health issues and cancer.

The Workplace and Reproductive Health

OHCOW professionals and staff have experience investigating workplace conditions that point to increased health risks, including hazards to the reproductive system and organs. If you think workplace conditions may have caused your fibroids or other reproductive health issues, contact us.
