Many people discover their passion later in life, but Dr. Nassir has always been firmly devoted to the science of healing. From the early age of fourteen, he knew he would pursue a career in the medical field. 

His formal post-secondary education began in Canada at the University of Toronto. After completing two years of undergraduate studies, he moved to the United States to finish his degree at UCLA, one of California’s top research institutions. Dr. Nassir’s time at the University of California, Los Angeles, was integral in his future success as an esteemed physician. His passion for the healing arts fueled his studies, earning him acclaim among his peers and educators.

Here, he received the highly respected American Foundation for Urological Disease Research Scholarship for his outstanding performance in the program.

Dr. Nassir’s academic career at Cornell University was reaching new horizons when his father was diagnosed with terminal stage 4 prostate cancer. To be near his family during his father’s final months, Dr. Nassir made the difficult decision to transfer his medical schooling to UCLA.

Through this pivotal, first-hand experience, Dr. Nassir realized his calling in the field of oncology.

Dr. Nassir has been in practice for more than twenty years. He currently practices at his private practice, Cancer Care Institute, and is independently affiliated with Cedars-Sinai Medical Center. His success in his field can be attributed not only to his exceptional medical training and unshaken persistence but also to a deep and personal understanding of cancer and patient care.

Dr. Nassir understands that there is no such thing as “standard cancer,” so there shouldn’t be a standard approach to treating the disease. Instead, he takes a highly individualized, collaborative approach to patient care, offering novel therapies that are uniquely suited to your needs and circumstances. 

As cancer is a chronic disease, Dr. Nassir provides long-term care to help ensure the most positive possible outcomes. He has a unique understanding of the disease and stays with you and your family every step of the way, offering therapies, treatments, and dietary advice to help you make guided, well-informed decisions about your care. 

Today, Dr. Nassir’s reputation is widely celebrated in his community. Ratings from his patients and their families consistently spotlight his expertise and unyielding, compassionate approach. He is known as a gifted doctor and a compassionate man who strives daily to deliver hope and save lives.

In regard to his life mission and work, Dr. Nassir notes, “My hope is to continue to improve the quality of life for cancer patients, to turn incurable cancer from a death sentence into a chronic, manageable disease where people can live much longer and have satisfying lives.” Dr. Nassir is fortunate and humbled to have the opportunity to bring hope to cancer patients through individualized care and targeted cancer therapies.
