A Schnauzer had a gigantic mast cell tumour

This video shows the post-op care of the gigantic mast cell tumour in the right hind limb. This tumour recurred 6 years after surgery by Vet 1. Histology report of Vet 1 showed that there were malignant tumour cells at the margins of the tumour sent to the lab. The tumour recurred as a grape size and Vet 2 did a biopsy. Within a few days, it grew explosively to 3 sizes of a mango. Vet 2's colleague, a senior vet said that the biopsy could have provoked its growth. The dog was operated by Dr Daniel of Toa Payoh Vets. 

In conclusion, the lower stitches broke down a few days later. Re-stitching and more than 2 weeks of hospitalisation resulted in the wound closing to around 10 cm x 10 cm. The dog went home for further wound cleaning and nursing by the owners. This gigantic tumour (see images in a video to be produced) is malignant and in retrospect, Vet 2 might have to excise the tumour instead of doing a biopsy as standard operating procedure taught by the vet professors. In hindsight, it is easy for me to comment but biopsy is a standard operating procedure for tumours, commonly done in the human surgical fields too. For me, excision and histology. I don't perform biopsy to save medical costs for the owners.
