We need an expert opinion.?

Our 8yr old ***** was diagnosed with ovarian cancer 5 weeks ago, the tumor was removed and the vet gave her two months life expectancy because it is a rare and aggressive form of ovarian cancer. It had started to spread into her fatty tissue. Over the last 12 hours she has begun retching and has a small amount green discharge coming from her eyes. We are not sure if this is a symptom of the cancer or not. HELP!
