His patients can benefit from the insights of multiple experts, including physicians in the Medical Oncology, Pulmonary Medicine, Radiology, and Interventional Radiology departments.

Did You Know?

Believing that no two cases of mesothelioma are the same, Dr. Flores refuses to be shoehorned into the belief that extrapleural pneumonectomy is always better than pleurectomy/decortication or vice versa.

Dr. Flores strives to glean as much information as he can before performing an operation. This will allow him to give the patient the best outcome possible, even if it means waiting until after he has made the first incision to determine which surgery he will perform.


Born in New York, NY, Dr. Flores came from very humble beginnings. He was raised by his single mother, who encouraged him to dream big and work hard to achieve his goals. To help pay for his schooling, Dr. Flores worked several odd jobs, including driving a delivery truck.

Dr. Flores began his post-secondary education at New York University, where he earned an undergraduate degree in biochemistry. Dr. Flores then went to medical school at the Albert Einstein College of Medicine, completing his MD in 1992.

Dr. Flores spent the next five years completing his internship and residency in general surgery at Columbia-Presbyterian Medical Center, followed by a thoracic oncology clinical research fellowship in a joint-program by Brigham and Women’s Hospital and the Dana Faber Cancer Institute in Boston. Dr. Flores remained at Brigham and Women’s Hospital of Harvard Medical School afterward to pursue a residency in cardiothoracic surgery, which he finished in 2000.

With his formal education complete, Dr. Flores worked as a surgeon in a variety of positions at Memorial Sloan-Kettering Cancer Center and Memorial Hospital, both in New York, for the next decade.

After completing his residencies, Dr. Flores spent around 7 years at the Memorial Sloan Kettering Cancer Center in New York as an attending thoracic surgeon. While he was there, he established the current program to use VATS lobectomy.

He also published 2 studies showing its oncological effectiveness.

VATS lobectomy has comparable survival and recurrence rates to a standard thoracotomy, and it has fewer complications while requiring a shorter hospital stay.

In 2010, Dr. Flores took on two new roles: Chief of Thoracic Surgery at Mount Sinai Medical Center, and the Endowed Chair in Thoracic Surgery at Icahn School of Medicine. He still holds both positions but also became the Chairman of the Department of Thoracic Surgery for Mount Sinai in 2014.

Dedication to Mesothelioma Asbestos Diseases

Currently, he is continuing his research on the consequences to a patient’s health from being exposed to asbestos as the Principal Investigator of the Libby Epidemiology Research Program.

Additionally, Dr. Flores contributes to the National Mesothelioma Virtual Bank, which contains a wide variety of searchable biospecimens. This system helps doctors and researchers study mesothelioma, how it spreads, and what kinds of patient outcomes there are for the different treatment plans.

Throughout his career, Dr. Flores has participated in a dozen formal research projects, several of which focused on better understanding and treating mesothelioma. He has also written more than 100 peer-reviewed articles and has contributed to an extensive list of book chapters, abstracts, article reviews, and videos.

As a result of his vast expertise and knowledge of mesothelioma and lung cancers, Dr. Flores has given approximately 200 formal lectures and presentations at universities and symposiums across the globe. This work has taken him to dozens of foreign countries including Brazil, Italy, Germany, Switzerland, France, Tokyo, and China.

Dr. Raja Flores’ Medical Specializations

Over the course of his career, Dr. Flores strives to improve the quality of life and survival rates of his patients.

As a specialist at Memorial Sloan Kettering Cancer Center, he began to use VATS lobectomy to better understand the type of cancer presented before putting a patient through more invasive surgery.

Pleural Mesothelioma

Dr. Flores is a thoracic and cardiac surgical oncologist specializing in treating pleural mesothelioma.

“What we’re trying to do is help patients live longer with a better quality of life.”

– Dr. Flores

There is currently no agreement about whether extrapleural pneumonectomy (EPP) or pleurectomy with decortication (P/D) works better, and Dr. Flores refuses to pick a side.

Dr. Flores believes that the type of surgery will be determined by the disease stage and the kinds of therapies the patient will be undergoing as a follow-up (for instance, chemotherapy or radiation therapy).

He doesn’t believe that CT scans are able to effectively show the extent of the tumor.

Dr. Flores warns his patients that he won’t know whether he is only removing the lung’s lining (P/D) or if he will be removing the whole lung (EPP) until after he has made his first incision and can see the full extent of the cancer clearly.

One of the problems faced by oncologists is determining the type of cancer a patient has — mesothelioma or adenocarcinoma. Cancer type determines what treatment options are available.

This is why surgeons need to perform an open pleural biopsy or a VATS lobectomy procedure — where a diseased portion of the lung is removed using three small incisions, instead of the previous method where the chest cavity had to be opened.

With this tiny portion of a patient’s lung, the doctors can determine what kind of cancer a patient has, and which of the 3 cell types of mesothelioma (epithelioid, mixed, and sarcomatoid) they have. This information can help doctors determine the next steps.

This system leads to fewer complications for the patients, has a faster recovery time, and has the same level of effectiveness at determining cancer type as a standard thoracotomy.

Multidisciplinary Treatment

Dr. Flores continues to look for innovative new ways to treat mesothelioma because he believes that a cure will be found one day.

Until that happens, it’s important to constantly discover new methods for improving patient quality of life. One of the ways he does this is through a multidisciplinary approach.

The idea behind this approach is that a patient will benefit from being seen by more than one specialist across different fields like oncology or radiology.

Each specialist will see the problem from their own viewpoint. Specialists can work together, share knowledge and create the best treatment plan for the patient.

Dr. Flores’ Healing Philosophy

“We try to treat mesothelioma here with the patient’s best interest at heart, as I’m sure everybody else does.”

– Dr. Flores

Dr. Flores uses a trimodal approach to treating most mesothelioma patients but believes that the patients’ needs always come first. Dr. Flores and his team at Mount Sinai recognize that the right treatment for one person may not be the right treatment for another.

“What we do here is tailor the treatment to the individual patient. If you have a 35-year-old woman who’s newly married and just had a stage 2 mesothelioma diagnosis — she’d be treated very differently than an 80-year-old male who’s stuck in a wheelchair and has stage 2 mesothelioma. So, you need to treat the patient and not just the stage of the disease.” – Dr. Flores.

Dr. Flores also favors minimally invasive techniques and is an advocate for video-assisted and robotic surgery. For mesothelioma patients, he always tries to spare the lung, favoring pleurectomy/decortication whenever possible.

“Here at Sinai, what we try to do is focus in on sparing the lung, so if there is a chance to spare that person’s lung and do something called a pleurectomy/decortication, that’s what we attempt to do.”

– Dr. Flores

However, he believes there are times and cases when an extrapleural pneumonectomy (EPP), which removes the lung, is the more appropriate treatment option. For example, his team would perform an EPP if the lung has already lost its ability to function, due to the spread of mesothelioma. This willingness to perform both standard mesothelioma surgeries is somewhat unique amongst mesothelioma specialists.

Working With Dr. Flores

Because of his background, Dr. Flores finds it very easy to relate to his patients because he understands their lifestyle and livelihood.

He is highly personable and provides hope to his patients while giving them the best quality of life he can. This is why Dr. Flores is so willing to work with others and hold off judgment for surgery type until he has all the information before him.

Dr. Flores is one of the best in the mesothelioma field. His patients can rest assured that not only is he a caring physician, but he’s also one of the most capable surgeons.
