Hot and cold beverages, ice and light snacks are available for patients in the Indian Path Medical Center and Johnson City Medical Center Infusion Therapy areas.

  • Comprehensive Breast Center.  We guide women at high risk for breast cancer through the care process, and we offer digital imaging, fast access to care and high-risk genetic screening.

  • Radiation Therapy.  Radiation therapy is offered at three locations close to home, featuring highly trained staff and physicians and state-of-the-art technology.

  • Radiation Therapy treatments may be a one- or two-time event or may last many weeks. Your first or second visit may take several hours, but most ongoing treatments take less than an hour in the department.

Your primary care physician will continue to manage your other health care needs.
