looks at both conventional and alternative options. I did not find alot on what I was looking for: lung tumours in dogs but on the general topic this book was very informative .
A clear, comprehensive, sensible introduction and overview--as much information as the non-professional needs. There's one area that may set off unnecessary alarms. The author gives encouraging news and advice concerning pets with cancer, treatments, and prognosis with one notable exception: cancer that has been caused by vaccination, for which, the author says, there is no cure. This led me to do a Google search and discover similar grim information, except magnified and multiplied.
The truth appears to be that the problem--although a cause-effect connection has been established in some instances--is extremely rare and that worse harm may be inflicted upon a pet by not vaccinating it. I learned the foregoing not from my local vet but by driving kitty across state to the University of Wisconsin Veterinary School--which in addition to addressing the concern about vaccinations was able to determine that my local vet's diagnosis of cancer was a misdiagnosis (common bacterial infections can lead to limping, bone erosion and other symptoms of cancer).
Good general overview

My cat way diagnosed with cancer about 5 months ago. I found this book to be the most helpful in understanding her cancer (GI lymphoma) without being overly filled with jargon. It was also the best on helping me understand the treatments available (and why some weren't for my cat) but I wish it had gone into more technical detail about the various medications and what they do for chemotherapy. Unfortunately, none of the books I found provided that information. I like the fact that the book separates out discussion on dogs and cats. I would definitely recommend this book for anyone with a pet with cancer.
