1351. Biopsy of breast tumour in an old cat

Female cat, spayed 12 years.

Right armpit area - a lump was detected and excised by Dr Daniel in Oct 2013. The owner stated it was a cyst. To me, it looked like a skin tumour and I recorded this down. No histology was done.

On April 5, 2014, the owner came with the cat not eating and a bigger lump. Now, around 4 cm x 2 cm x 1 cm. He wanted a biopsy done by Dr Daniel and sent to the lab.

Results from the lab
2 strips of tissue 1.0 cm x 0.4 cm x 0.2 cm.   

Diagnosis: Aypical ductal proliferation suspicious of low-grade ductal carcinoma.  What's App the report to the owner.
