Oncology

Leading Community Cancer Care since 1963

At Buffalo Medical Group, our team of surgeons, oncologists and care coordinators are here to help you and your loved one achieve the best possible outcome with compassionate, individualized cancer care.

Radiation, chemotherapy and surgery are just one aspect of Buffalo Medical Group’s cancer care (oncology). Relationships and compassion also play a vital role—and can make all the difference. At Buffalo Medical Group, we provide the most advanced cancer treatments, and coordinate with many national cancer centers when appropriate. But we also remember there’s a person behind the patient. When you come to us, we take the time to work with you and your caregiver, providing coordinated care through every step and every stage you may encounter. And from the moment you’re diagnosed to whenever you need us, we’ll be there. Just as we’ve been for almost 60 years.

With convenient locations in the Northtowns, Southtowns and Downtown Buffalo, cancer care is never far from home. New patient appointments are available within one week or less.

Complete cancer care—from screening to diagnosis, to treatment, to survivorship.
