Hallow Dear, At the outset, let me assure you that caesarean section has nothing to do with your heavy uncomfortable periods and fibroids. In fact, your heavy painful periods are due to fibroid uterus. Had it been only heavy menstruation, thermal ablation would have helped you. Thermal ablation is destroying the lining of the uterus (endometrium) by very hot fluid. It is the endometrium of the uterus which gets thrown out as menstrual discharge. Hence, once the endometrium is destroyed, there is no menstruation, and no heavy bleeding. However, you have fibroid uterus. This fibroid(s) will remain in the uterine cavity though your menstruation has been stopped by thermal ablation. This fibroid can undergo atrophy after menopause, however, remains as a vulnerable tissue for any type of degeneration including cancer. I would advise you to go for hysterectomy and not thermal ablation. Of course, it is advisable to undergo hysteromicroscopically directed biopsy of the endometrium to find out the status of the endometrium before hysterectomy. In about 30% of cases, cancer of endometrium is known to coexist with fibroid since both these conditions are result of high oestrogen condition. I hope this helps you. Dr. Nishikant Shrotri
