Could pregnancy loss signal future cancer risk? new study investigates
NCT ID NCT03969498
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study followed over 1,500 women who had pregnancy losses and were tested for antiphospholipid syndrome (APS) and other clotting disorders. Researchers compared cancer rates among women with APS, those with other clotting gene changes, and those with no clotting issues. The goal is to see if having APS or other clotting problems raises the risk of developing cancer later in life.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- What this could lead to
- If this study finds a link, it could help identify women with pregnancy loss who may need cancer screening.
- What could go wrong
- This is an observational study, not a treatment trial. It cannot prove cause and effect, and results may not apply to all women.
