*NOTE... The cancer institute is located on the Plainville/New Britain line and is adjacent to the Medical Arts Center building. The address on the website for the cancer institute is 183 North Mountain Road, New Britain, but this address does not work with GPS. So please use 201 North Mountain Road, Plainville for GPS, which is the address for the adjacent Medical Arts Center. (Confused? I am too... Give me a call if you need help clarifying! 203-213-6495)
