What was the "abdominal Surgery?"
Hysterectomy seems likely. Benign cysts over and over causing discomfort/debilitation over and over. Then, one of the cysts isn't benign or they find some suspicious activity/growth in the liver or lymph nodes during surgery or during post-surgical pathology and your care plan changes rapidly.
Cancer is hard enough to go through for any individual. Just my guess/opinion but it's got to be even more mentally taxing as the mother and/or father of a young family.
