Cancer Treatment for Pets: Compassionate Oncology CareA cancer diagnosis can be overwhelming—but you don’t have to face it alone. Our veterinary team is here to guide you through every step, offering advanced treatment options and compassionate care to help your pet live more comfortably, for as long as possible.What Is Veterinary Oncology?Veterinary oncology focuses on the diagnosis, treatment, and management of cancer in pets. Just like in humans, cancer can affect various parts of the body—from skin and lymph nodes to organs like the liver, spleen, or lungs.Common types of cancer we see include:<ul><li>Lymphoma</li><li>Mast cell tumors</li><li>Soft tissue sarcomas</li><li>Osteosarcoma (bone cancer)</li><li>Mammary gland tumors</li></ul>We tailor each treatment plan to your pet’s condition, age, and overall health to ensure the best possible outcome.How Do We Diagnose Cancer in Pets?Early detection is key. If your pet has a lump, swelling, or unexplained symptoms like weight loss or lethargy, we may recommend:<ul><li>Digital X-rays or ultrasound to evaluate internal structures</li><li>Bloodwork and lab tests for overall health screening</li><li>Fine needle aspiration or biopsy to analyze abnormal tissue</li></ul>These tools help us accurately diagnose the type and stage of cancer and determine the most effective treatment path.Treatment Options We OfferOur goal is to not only treat the disease, but also to support your pet’s comfort and quality of life. Depending on your pet’s diagnosis, treatment options may include:<ul><li>Surgical removal of tumors (when localized and operable)</li><li>Pain management and supportive care to ease discomfort</li><li>Laser therapy or alternative therapies to reduce inflammation and aid recovery</li></ul>In some cases, we may coordinate with board-certified oncologists for specialized treatments or second opinions.What to ExpectCancer care is never one-size-fits-all. We’ll work closely with you to explain the diagnosis, review your options, and create a realistic plan—whether that means aggressive treatment or palliative care. Throughout the process, we focus on:<ul><li>Minimizing side effects</li><li>Monitoring progress with regular check-ins</li><li>Providing emotional and medical support</li></ul>We’re here to answer your questions, listen to your concerns, and help you make informed, compassionate decisions.A cancer diagnosis doesn’t mean giving up—it means choosing the best care possible, guided by a team who truly cares. We’re here for you and your pet every step of the way.🐾 Looking to keep your pet healthy and happy? Visit us—we’re here to support every step of the way.

We offer compassionate cancer care tailored to extend quality of life and support your pet's journey.
