How I found out I had uterine cancer, what I wish I had known, and what everyone with PCOS should know about their period: what to track and how to measure progress

My Unexpected Uterine Cancer Diagnosis at Age 48

At 48, I had been living with PCOS for over twenty years. My periods had always been irregular—sometimes skipping three or four months—but I normalized it. Then came the heavy bleeding that soaked through pads in under an hour. An ultrasound revealed a thickened endometrial lining, and the biopsy confirmed endometrial cancer. The tumor was caught at stage 1A, which meant a hysterectomy saved my life. Looking back, I wish I had understood how unopposed estrogen from years of anovulatory cycles quietly fueled endometrial hyperplasia, the precursor to cancer.

What Every Woman with PCOS Needs to Know About Her Period

PCOS disrupts ovulation, leaving the uterine lining exposed to estrogen without the balancing effect of progesterone. This imbalance raises lifetime risk of uterine cancer by three to four times, especially after age 45 when metabolic changes accelerate. In my practice at CFP Weight Loss, I emphasize that irregular bleeding after 40 is never normal. Persistent spotting, cycles longer than 35 days, or bleeding after sex all warrant immediate evaluation with transvaginal ultrasound and possible biopsy.

What to Track to Protect Your Health

Use a simple app or notebook to record: cycle length, bleeding heaviness (pad/tampon changes per hour), presence of clots larger than a quarter, pelvic pain, and any bleeding between periods. Also track weight, fasting blood glucose, and waist circumference. These numbers reveal how insulin resistance drives androgen excess and estrogen dominance. In The Metabolic Reset Method, I outline measuring progress by aiming for 5-7% body weight loss within 90 days—this alone can restore ovulation in 60% of women with PCOS and dramatically lowers cancer risk by improving insulin sensitivity.

How to Measure Real Progress Beyond the Scale

Focus on three markers: cycle regularity moving toward 21-35 days, fasting insulin dropping below 10 μU/mL, and waist measurement decreasing by at least two inches. Add daily 20-minute walks despite joint pain—these gentle movements reduce inflammation without aggravating knees or hips. Combine with a moderate-protein, lower-carb plate method: 25 grams protein, ½ plate non-starchy vegetables, and ¼ plate complex carbs. This approach fits busy middle-income schedules and works alongside diabetes and blood pressure medications. Early tracking and 5-10% weight reduction can cut endometrial cancer risk by up to 40%.
