Can you pick it up and roll it in her skin, or does it feel anchored?
Cider had a very large pea sized lump appear on her side in march. I put it off as I didn't really want to know. I was afraid. Then 4 more similar ones appeared but smaller. Took her in, in June and had them removed. They were fat, but I was pretty scared...
After having them removed they feel she will get more but we will keep an eye on them if similar..
