The short explanation
Extra body weight and diabetes are both linked to a higher risk of womb cancer, also called endometrial cancer. Fat tissue produces oestrogen, and higher oestrogen levels without enough of the balancing hormone progesterone can make the womb lining grow more than usual. Diabetes and insulin resistance are thought to add to this effect. A higher risk does not mean you will get womb cancer. It means it is especially important to know the warning signs and act on them. The most important sign is abnormal bleeding: bleeding after menopause, bleeding between periods, or periods that become much heavier or irregular around your age. Reaching a healthier weight and keeping diabetes well controlled can lower risk.
What depends on your situation
The parts of this that change from woman to woman. Uncertainty is stated, not hidden.
- PCOS, never having been pregnant, late menopause and some medicines also increase risk.
- There is no routine screening test for womb cancer in women at average or moderately raised risk, so reporting symptoms early is the main way to catch it.
- Even modest weight loss and regular activity can improve blood sugar and hormone balance.
What this answer cannot determine
The boundary of online education. These need a clinician who can see you.
- This cannot tell you your exact risk. Your doctor can advise based on your history and any symptoms.
Questions for your clinician

- What symptoms should make me come back?
- Are my periods normal for my age, or do they need checking?
- How can I lower my risk?
