Hi Teresa,
Get ready for the most challenging months/years of your life. I was my husband's caregiver for 4 years and 3 occurences of OC. I don't know about vascular invasion, but my husband did have Peri-neural Invasion or PNI, which is one reason his cancer kept recurring. I just lost him in June, which still doesn't seem real to me. We were married almost 25 years, and there is nothing harder. I am not the only caregiver on this site that has lost their partner to this horrible disease, and I'm sure there will be more. I just hope you won't be one of them. I think Brian needs to be kicked in the arse (as Liz would say), and I would not hesitate to do it if I knew where he lived! My husband was a big strong farmer when this hit him, and he lost everything. His ability to work, communicate clearly, and even ride his Harley at the end. If you are interested you can click on my name at the left and select homepage. I kept a blog about our experiences and also photos. Please tell Brian that if he loves life, he HAS to have the regular chemo/radiation treatment for OC. This is not a cancer to mess around with, or to take your time deciding a plan of treatment on. He needs the big guns NOW, there may not be a later.
Please take care of yourself!!!
Lori
