I had an ovarian cyst and both ovaries removed in May 2020 by admoninal incision, as a hysterectomy had been advised, which I had agreed to.
It transpired that the hysterectomy had not been necessary, as what the surgeons had all assumed were massive fibroids in my uterus when they viewed all the scans, was in fact an ovarian cyst weighing after removal 1300 metric grams that had pulled the ovary down infront of the uterus.
I was advised not to lift anything weighing more than I kg until the surgical clamps closing the incision had been removed and to rest whenever tired.
For the first three weeks or so, I felt sick if I got too tired, so resting was fairly easy. After that I have had no trouble at all, and have fully recovered my strenght, and am feeling stronger and healthier than I did for at least a year prior to the op. I was 68 at the time it was done.
I hope you will have as good treatment and as easy a recovery as I did.
My advice is: do a little less than the doctors advised to start off with, rather than risk doing too much, but do take small walks every day to start off with.
Let us know how you get on.
My cyst was analysed and contained no indications of cancer. I expect you will be just as fortunate.
