Women with PCOS have NOT been confirmed to have a higher risk of endometrial (uterine) cancer than any other group of women, however, anyone with a uterus can get endometrial cancer. The more out of whack your system is, the greater the chance. Not getting your period is a sign of severe hormonal imbalance, and this needs to be addressed, not only in relation to endometrial cancer.
PCOS, in particular insulin resistance, can cause a great deal of damage to your body if left unchecked. For instance, women with PCOS have a much higher risk of cardiovascular disease, stroke & diabetes than the general population. That’s just as concerning as endometrial cancer.
