I have had my horse, Lizzy vetted today as I am selling her. However during the vetting the vet noticed a large hard lumpy mass above Lizzy's eye (all around the sub orbital depression). It feels bony to me, not soft at all. I have had Liz for 3 years and not took any notice of it until now, when it's been pointed out to me. Now I can see that her right side is more lumpy than the left. I have booked her in for a head x-ray tmrw but i'm really worried it's something sinister?! Could it be a cancerous lump? I'm pretty sure it hasn't changed in the 3 years I have had her.
Would appreciate any advice
