Docs Remove Woman's 56-Pound Tumor Surgeon: 'We were totally shocked' By Nick McMaster, Newser Staff Posted Aug 27, 2010 1:53 PM CDT 8 comments Comments Doctors weren't expecting a 56-pound tumor. (Shutterstock) (Newser) – Surgeons in Argentina removed a 56-pound tumor from a woman's uterus, the AP reports. The cancerous mass was 19 inches across: "We were totally shocked," says the lead surgeon. The woman had felt a growth in her abdomen for a year but chalked it up to weight gain. She's home again but under observation because the tumor (nowhere near the record 300-pound cyst removed from a US woman) was malignant.
