Welcome to a higher standard of care. Welcome to Cancer Treatment Centers of America. Cancer Treatment Centers of America has regional locations nationwide, including a location in Goodyear, Arizona. At Cancer Treatment Centers of America, we hold ourselves to a higher standard – the Mother Standard® of Care. Every doctor, clinician, nurse and therapist treats you with the respect, concern, compassion and commitment they would want a member of their own family to be treated with in the fight against cancer.
