There are many different ways to detect and diagnose cancer. It can appear as a mass, it can be discovered on routine X-ray, or it can manifest itself through some clinical symptoms. Proficient diagnostic skills and lab work may also indicate the existence of a cancer. Just like with humans, early detection is essential for successful treatment. Here at the Pets R Us Aurora Animal Hospital, we have performed many surgeries for the removal of benign and malignant tumors with a high success rate.
