Eric Bent, MD, PhD
We post reviews for MSK healthcare providers who have at least 30 patient experience surveys completed. If you do not see reviews for a provider, it may be because they do not yet have enough survey responses, or the provider may not be part of the group of healthcare providers included in the survey.
Only outpatient providers are included in the survey. Healthcare providers who only work in the hospital or in urgent care are not included in the survey. Pathologists or researchers who do not provide direct care to patients do not have reviews.

Get to Know Me
I am a radiation oncologist and medical oncologist focused on treating people with genitourinary cancers. This includes bladder cancer and prostate cancer. I see patients at the David H. Koch Center for Cancer Care at Memorial Sloan Kettering Cancer Center (MSK) and at Memorial Hospital, which is MSK’s main hospital.
I am one of the few doctors in the United States who is trained in both radiation oncology and medical oncology. This allows me to be a single stop for patients who need both medical therapies and radiation therapy. I focus on combining these treatments to get the best possible treatment results while reducing side effects and improving quality of life. Using a personal approach, I treat each patient with the best possible therapies for them rather than focusing on a single treatment type.
I am also an expert in organ preservation for patients with prostate and bladder cancer. This means that I work to find treatments that destroy the cancer while keeping your bladder or prostate to help you maintain your quality of life. I also treat advanced stage prostate and bladder cancer that has spread to other parts of the body.
A cancer diagnosis can be overwhelming and scary. When I meet with you and your family, I take the time to explain the diagnosis and treatment options. I partner with you to make the treatment choices that are best for you.
In addition to seeing patients, I also engage in research. I study the latest scientific advances and focus on how we can use treatments such as immunotherapy, targeted treatments, and hormonal therapy along with radiation. I am committed to using the newest, most effective tools to give you the best possible care.
I'm a radiation oncologist, which is a cancer doctor with special training in using radiation therapy (RT) to treat cancer.
I'm a genitourinary (GU) medical oncologist, which is a cancer doctor who specializes in genitourinary (jeh-nih-toh-YOOR-ih-nayr-ee) cancers. This includes bladder, kidney, penis, prostate, and testicular cancers.
