Summary

This study tests whether giving a dye called Cytalux a few days before surgery works as well as giving it closer to the operation. The dye makes tumors glow under a special light, helping surgeons remove them more completely. About 106 adults with suspected lung cancer or confirmed ovarian cancer will take part. The goal is to see if the longer window is just as effective for spotting cancerous and non-cancerous lesions.
