Upon returning to Switzerland from Somalia in late September 1992, Hepburn developed abdominal pain. While initial medical tests in Switzerland had inconclusive results, a laparoscopy performed at the Cedars-Sinai Medical Center in Los Angeles in early November revealed a rare form of abdominal cancer belonging to a group of cancers known as pseudomyxoma peritonei. Having grown slowly over several years, the cancer had metastasised as a thin coating over her small intestine. After surgery, Hepburn began chemotherapy.
