I drank Ocean Spray Cranberry juice the whole time I was on chemo, especially alot during chemo infusion and the week or so after. My CA125 came down dramatically. I plan to start drinking it again since it seems to have an anti ovarian tumor cell affect from this study. It sure can't hurt. For those of you on chemo now, it can't hurt and will keep you hydrated, keep the bladder infections away, and maybe help the chemo kill cancer cells. If you don't like the taste, cut it half and half with water. I did that with many juices when on chemo since it was easier to drink alot of it that way.
