Dr. David J. Cancian, MD 521 Mount Auburn Street, Watertown, MA 02472

"Best primary care physician I have ever had!"

"If I could, I wouldn't give him ANY stars as he is literal THE worst medical professional ever. My grandfather was a patient of his. One day I noticed a bump on the back of his head in 2020, so I told my grandfather to get it checked out so he did. Dr Cancian said it was fine and nothing was wrong with it, suddenly in early 2021 (around March or April) it became an issue and my grandfather was diagnosed with melanoma. By the time he was diagnosed, every treatment tried failed. It was already too late. On Feb 22, 2022 my grandfather died due to Dr. Cancian's negligence to his patients. Seems to me like he is out golfing or vacationing more than he is actually taking care of his patients. After reading the reviews and comments here, this story sounds very similar to some of these other families stories and its a crying shame this man is still able to be in the medical field."

"Dr. Cancian is one of the worst medical providers I’ve ever had. He sent me to an infectious disease doctor after doing a series of tests and that specialist said “I don’t really understand why you’re here. The tests your doctor did clearly show you have mono.” Ridiculous! Do not go here!"

"Office staff very unprofessional"

"Dr. Cancian misdiagnosed my family member. He did not perform any preliminary tests which would have shown their cancer in stage 1. Ten months after first presenting symptoms to Dr. Cancian, my family member was diagnosed with stage 4 cancer. Ten MONTHS begging for x-rays and a cat scan-- he refused and prescribed an anti- anxiety medication. Shortly after diagnosis sibling died. Oh-- he also told my sibling that they were terminally ill over the phone. Please be careful if you are examined by him!!! Get a second opinion. My sibling died at 29 years old, make sure to walk away from him if he refuses preliminary, life saving tests- and prescribes you Valium."
