Cancer in dogs
Treatment options vary and depend on the type and stage of cancer. Common treatments include surgery, chemotherapy, radiation therapy, amputation, and immunotherapy. A combination of therapies may be used. Knowledge and treatment of cancer have increased significantly in the past three decades. Survival rates have also increased due to the increase prevalence of canine cancer treatment centers and breakthroughs in targeted drug development. Canine cancer treatment has become an accepted clinical practice and access to treatment for owners has widely expanded recently. Cancer-targeting drugs most commonly function to inhibit excessive cell proliferation by attacking the replicating cells. However, there is still a prevalent pharmacy gap in veterinary oncology.

But the "equation" of cancer is much more complex. And the massive failure of "targeted therapies" to cure cancer is the illustration. These targeted therapies have cured only 50% of HER2 positive breast cancers treated with adjuvant therapy after local cancer treatment. That is 3% of breast cancers. That's all. Moreover, their participation in the "chronicization" of the breast and prostate - even some colon or rectum - is very minor compared to chemo / hormonotherapy, much better used today.
