Tinker's results came through today and it could have been better news - the lump was a fibrosarcoma which is a cancerous growth that can be quite aggressive. This was not want we wanted to hear. The vet said that he took away a lot of tissue around the edge of the tumour and that he hopes that will do the trick. However, he said that we have to keep inspecting the site for any regrowth over the coming months. Tinker is very happy within himself so I am glad we had it done but the uncertainly is going to be a worry over the next few months.
Poor little fellow, he's such a good natured cat and I really don't want him to suffer at all.
