https://www.vetsurgeon.org/f/clinical-questions/20887/neutering-and-mammary-tumours Quick question. Is it now outdated advice to advise speying a bitch with suspected mammary tumours? Thanks! en-USTelligent Community 10https://www.vetsurgeon.org/thread/125650?ContentTypeID=1Wed, 03 Dec 2014 16:01:45 GMT146601cc-3922-4be7-9974-7e1d4e45a66b:e410f84c-88b5-483d-80e6-df55448bb041Karen Eggleton<p>Hi Gerry, I think I love you <img src="https://www.vetsurgeon.org/emoticons/v2/Very_happy_smiley.png" alt="Very happy" />. I have to argue the case with an insurer and we were laughing that I may be old school but perhaps my outdated advice had come back in vogue! Many thanks!</p><div style="clear:both;"></div>https://www.vetsurgeon.org/thread/125649?ContentTypeID=1Wed, 03 Dec 2014 15:51:42 GMT146601cc-3922-4be7-9974-7e1d4e45a66b:6cabdc53-9ec6-44e9-9c41-965038dd4ac8Gerry Polton<p>Quick answer: No</p> <p>Long answer: It was but now the outdated advice has become outdated.</p> <p>My opinion: It&#39;s all a bit of a merry-go-round so don&#39;t waste your time trying to piece the evidence-base, such as it is, together. if you are interested in the literature on the subject, read Veronika Kristiansen&#39;s paper in JVIM (2013 pp<span>935-42) but be aware that this only relates to speying at the time of <span style="text-decoration:underline;">benign</span> mammary tumour management.</span></p> <p><span></span>My advice: Judge each case on its own merits. If you have a patient with aggressive malignancy, don&#39;t bother speying because the malignant disease is more likely to kill them than the tumour that has not yet even started. By contrast if the bitch has a benign tumour, definitely consider the spey procedure to reduce the risk of further tumours which could be either benign or malignant.</p> <p>Gerry</p><div style="clear:both;"></div>
