Endometrial cancer every — PCOS: More Than Just Irregular Periods
Polycystic ovary syndrome (PCOS) is the most common endocrine disorder in women of reproductive age, affecting an estimated 8–13% of women globally and up to 20% in some South Asian populations including India. It is characterised by a combination of irregular or absent ovulation, elevated androgen levels (causing acne, excess hair growth, or hair thinning), and polycystic-appearing ovaries on ultrasound. You need only two of these three criteria to be diagnosed with PCOS.
What is less widely appreciated is that PCOS carries significant long-term health implications beyond fertility — including an elevated risk of endometrial cancer that all women with PCOS should understand.
Why PCOS Increases Endometrial Cancer Risk
The mechanism is oestrogen without progesterone. In a normal menstrual cycle, ovulation triggers progesterone production in the second half of the month. Progesterone opposes oestrogen and causes the uterine lining to shed. In PCOS, ovulation is irregular or absent — meaning the uterine lining is continuously exposed to oestrogen without the balancing effect of progesterone. Over months and years, this unstimulated growth can progress: normal endometrium → endometrial hyperplasia → atypical hyperplasia → endometrial carcinoma.
Women with PCOS have approximately a threefold increased relative risk of endometrial cancer compared to the general female population. This does not mean most women with PCOS will develop cancer — the absolute risk remains relatively low — but it does mean surveillance matters.
Additional Risk Factors That Compound PCOS Risk
- Obesity — adipose tissue is an additional source of oestrogen production; PCOS and obesity frequently co-exist
- Insulin resistance and Type 2 diabetes — common in PCOS; insulin stimulates endometrial proliferation
- Nulliparity — women who have never been pregnant have fewer progesterone-dominant cycles
What Every Woman with PCOS Should Do
- Do not allow more than 3–4 months without a period without medical review — this represents unopposed oestrogen exposure
- Report any irregular bleeding, particularly in the perimenopause, promptly
- Use hormonal contraception (combined pill or progesterone-only) or cyclical progesterone if not trying to conceive — this protects the endometrium
- Pursue lifestyle modifications (weight management, regular exercise) to reduce insulin resistance
- Ask for an endometrial assessment if you are perimenopausal with a longstanding PCOS history and heavy or irregular bleeding
