Treating Mesothelioma Patients in New York
Flores believes his upbringing — his background — is one reason he relates so well to the patients he treats with mesothelioma, mostly men exposed to asbestos in blue-collar occupations.
Nothing came easy for him growing up in a working-class neighborhood near the meat-packing district of Manhattan, not far from where he practices medicine today.
“Many of them are blue-collar guys, insulators, asbestos workers, pipe fitters, shipyard workers,” he said. “I can identify with them, and they can see that I know how this disease is hitting them.”
The passion Flores has for the patients he treats is often what sets him apart, willing to do whatever it takes for his patients.
“At the end of the day, patients just want to feel like you did everything you possibly could, that you didn’t leave any stone unturned, in trying to help them,” he said. “They want to know you give it everything you have. And I do. This is not a job for me. It’s a calling.”
