Dr Paola Gehrig talks to ecancer at the 2012 International Gynaecologic Cancer Society meeting in Vancouver about the problems obesity causes in treating gynaecological cancers. As obesity rates increase globally, so do the number of cases of endometrial and ovarian cancer. Once diagnosed with one of these diseases, a patient's outcome is greatly effected by the extent to which they are overweight. Issues in surgical treatment include comorbidity, hypertension, diabetes and many others. In order to combat obesity and its effects, research has been done into minimally invasive, robotic surgery and laparoscopic surgery.
