Atticus is my Devon Jellybean's brother, a beautiful blue Burmese. They are best buddies, so beautiful together. Atticus is only just 2 years old. I took him to the vet because his microchip in his neck area was getting bigger. The vet said its not his microchip, looks like a tumour, could be a nasty sarcoma something or other, has to come out right away. He said this can happen allegedly at the point of vaccination.I was in so much shock. He is only 2. I thought it was the microchip!He goes in tomorrow to have it removed, three more days for pathology to come back. I also found another lump on his rear hind upper leg.I go to a vet clinic where there are several vets. When I took him in for vaccinations I asked about vaccinations causing tumours and in America some people vaccinate at the hind keg so worse case is amputation. I was told the vaccinations in America are different to ours so I didn't need to worry.Now I am so worried. This little boy is such a sweetie, such a treasure, I wake up with him in my arms most mornings....especially in winter.Does anyone know about this vaccinations causing cancer stuff?Has anyone had a lump at vaccination point and its turned out benign?I'm worried sick.
