Lymphoma is the most common cancer in cats. Modern treatment approaches can achieve remission and meaningful life extension with good quality of life.
Feline lymphoma treatment decisions are fundamentally welfare decisions. For small cell lymphoma, chlorambucil and prednisolone protocol achieves remission in over 70% of cases with minimal side effects, representing a genuine welfare gain. For large cell lymphoma, the calculus is more complex — aggressive chemotherapy can extend life but quality of life during treatment must be carefully monitored. Owners should understand that welfare-centered treatment is not about maximizing lifespan at any cost, but about maximizing quality of remaining life.
