ferret tumor

Question
I recently percused a young(around a month) male ferret.  We were checking it for and problems when I first felt a lump on the front right portion of the neck.  It is about a inch long and feels soft but firm.  We are wondering if this is a serious problem or just nothing to worry about.

I want to start by saying sorry for the delay in answering. I had some things going on here. I found a website that I think would be very helpful for you and would be a lot quicker than me trying to explain everything. Copy and paste this link into your web browser. I hope it helps. And again sorry for the delay. Have a great day.
