Learn · for pet parents
Calm, accurate explainers for owners. What the diagnosis means, what symptoms to watch for, what diagnosis and treatment look like at the vet, what questions to ask. We don't diagnose your pet — that's your veterinarian's job — but we can help you walk into the next appointment less lost.
Each article walks you through what the cancer is, what to watch for, how vets typically diagnose and treat it, what questions to ask, and where to look for clinical trials.
Bone cancer in a leg — the most common bone cancer in dogs.
Read article →Cancer of lymphocytes in multiple lymph nodes — the most common canine lymphoma.
Read article →Aggressive cancer of blood-vessel-lining cells, usually in the spleen.
Read article →The most common skin cancer in dogs. Behavior ranges from easily curable to aggressively metastatic — grade and stage drive everything.
Read article →The most common malignant oral tumor in dogs. Aggressive locally, and prone to spreading to lymph nodes and lungs — early detection makes a real difference.
Read article →A skin-only form of hemangiosarcoma. When caught while it's still confined to the skin, it's far more treatable than its splenic cousin.
Read article →Osteosarcoma of the skull, jaw, spine, ribs, or pelvis — the less common but locally trickier sibling of the limb form. Surgical accessibility drives the treatment plan.
Read article →A group of related tumors that arise from connective tissues — fat, muscle, nerve sheaths, fibrous tissue. They tend to grow locally, recur if undertreated, but metastasize less than many other cancers.
Read article →An aggressive cancer of histiocyte-lineage immune cells. Bernese Mountain Dogs are dramatically over-represented but any breed can be affected — early intervention matters.
Read article →The most common canine bladder cancer. Often presents like a stubborn UTI — and recurring UTI-like signs in a middle-aged or older dog deserve a closer look.
Read article →A locally invasive tumor of the apocrine glands of the anal sacs. Often found by your vet on a routine rectal exam — and can cause unusual systemic signs through high blood calcium.
Read article →Most canine thyroid tumors are carcinomas — and most are biologically aggressive, in contrast to the predominantly benign thyroid tumors common in cats.
Read article →About half of mammary tumors in intact female dogs are malignant. Early spay before the first heat dramatically reduces lifetime risk — but for diagnosed tumors today, prompt surgery is the priority.
Read article →A keratinocyte-derived cancer most commonly seen in the oral cavity, on the digits (toenail beds), or on sun-exposed skin. Location drives treatment.
Read article →Tumors of the nasal cavity — most often adenocarcinoma, chondrosarcoma, or squamous cell carcinoma. Locally destructive but slow to metastasize. Radiation is the workhorse therapy.

Articles are written for pet parents — not for veterinarians, not for journalists, not for investors. We use plain English, name what's uncertain, and end every piece with a reminder to talk to your vet.
All articles are educational only. Canine articles draw on peer-reviewed veterinary oncology literature. Feline articles carry a named reviewer's credentials and last-reviewed date at the top of the article — the reviewer byline appears only when an actual reviewer record is on file.
