If you were just diagnosed today
Two things matter in the first days, before any treatment decision: understanding what you are facing, and preserving the option to act. Start with these.
Preserve the tumor sample
If surgery is coming, how the tumor is stored decides which future options stay open. A simple request to your vet, explained.
What blood tests can and can't do
Screening and early-detection tests, what the peer-reviewed data actually shows, and the honest catch.
Guides by cancer type
Deep, cited guides organized by diagnosis. Each pillar walks you from what the cancer is through the full range of treatment options.
Hemangiosarcoma
An aggressive blood-vessel cancer, often of the spleen or heart. The disease, the survival numbers, immunotherapy, the vaccine landscape, and where personalized approaches fit.
Melanoma
Oral and skin melanoma in dogs, the treatment landscape, and the strong human precedent for personalized vaccines.
Mast cell tumors
The most common canine skin cancer, how grade and stage drive prognosis, and the treatment options.
More cancer types
Osteosarcoma, lymphoma, soft-tissue sarcoma and others are being added as each guide is written and reviewed.
Understanding treatment and vaccines
Cross-cutting explainers that apply across cancer types, for when you want to understand how the newer options actually work.
How personalized cancer vaccines work
Plain-language walkthrough of how a vaccine can be built from a single dog's own tumor.
Personalized vs. shared-antigen vaccines
The two families of dog cancer vaccine, how they differ, and what the evidence says about each.
Read the evidence honestly
The single most useful skill for a cancer decision is telling a strong result from a weak one. Our guides label every claim by the strength of its evidence, and cite the primary source.
