According to the private Capital Health Hospital Group, it was the largest such tumor ever to be removed worldwide.
The 35-year-old mother of three has been undergoing chemotherapy in Berlin since September 2008 to shrink the tumour enough for safe removal.
Removing the growth – which was one-third of the woman’s body weight – required five operations, the hospital said.
The woman, diagnosed with a malignant bone cancer called chondrosarcoma in 2003, came to the Berlin hospital after refusing to have part of her pelvis amputated.
By the time she reached Berlin, the tumour had gotten so big that the woman could no longer walk. The growth was tearing through her skin and threatened to obstruct her bowels.
“She was in a desolate state,” head surgeon Dr. Heinz R. Zurbrügg told journalists on Friday.
When the follow up examinations show no further tumours, the woman will have a missing section of her pelvis replaced with a tailored implant and an artificial hip joint, the hospital said.
Appearing before journalists in a traditional Arab abaya, the woman said she felt “born again,” and looked forward to standing before the doctors in her home of Kuwait who told her there was “no hope.”
