Can endometriosis grow after a hysterectomy?

Yes, but less common. A hysterectomy is a surgery involving the removal of the uterus, not necessarily the ovaries. The ovaries produce the hormones that can drive growth/stimulation of endometriosis. So, if ovaries are left in place, endometriosis may be more likely to grow after a hysterectomy.
Yes. Endometriosis grows from estrogen, produced by the ovaries. So endometriosis can still be a problem even after hysterectomy.
