Could a simple injection replace major surgery for ovarian cancer staging?

This study tests a sentinel lymph node technique, where a small amount of radioactive tracer and dye is injected to find the first lymph nodes that might contain cancer. In 200 women with early-stage ovarian cancer, doctors will compare this method to the standard approach of removing many lymph nodes. The goal is to see if the less invasive technique is accurate enough to replace the more extensive surgery, which could mean fewer side effects and faster recovery.
