I have a 14.2hh 8-9 yr old mare on loan.She has a tumor on her left ovary. Her owner told me it wouldn't affected her in any way other than if she was put into foal. I have her 3 months and was hoping to buy her if she was ever to be sold. So, I had her scanned be my vet last week. He said her left ovary was a total mess. He said he wasn't familure with this kind of tumor but said it had got bigger from when she was scanned last year. He adviced me not to buy her if ever she was to be sold. She is in good condition at the minute, but he couldn't say for sure how long she has, could be 10 years or much less.
I'm just not sure weather to continue having her on loan or look for something else. I have her for as long as I want but I'm worried I go out one day and she's dead. I'd hate to see her suffer knowing there's nothing I can do. Would I be wise keeping her even tho she's going to get very ill or should I look for something else? Obviously its up to me but I just need som advice.
