Practicing since: 2007

Dr. Eugene Ahn, MD, first dreamed of finding a cure for cancer when he was 5 years old. “My father was a hematologist/oncologist, and I always had a strong desire to improve our understanding and treatment of cancer,” says Dr. Ahn, Medical Director of Clinical Research at Cancer Treatment Centers of America® (CTCA), Chicago, which is located between the Chicago and Milwaukee metro areas.

Dr. Ahn earned his Bachelor of Arts degree in Biology at Yale University in 1993. He completed his Doctor of Medicine degree at the University of Miami in 1997. His postgraduate training, from 1997 to 2007, included a residency in internal medicine at the University of Utah, fellowships in infectious disease and hematology/oncology at the University Miami, and a National Institutes of Health-funded research fellowship in microbiology/immunology.

From 2007 to 2014, he served as faculty at the same institution, and as Assistant Professor, he was the principal investigator on numerous clinical trials focused on improving the treatment of breast cancer and other diseases. His work is published in renowned journals, including Breast Cancer Research and Treatment, Clinical Breast Cancer and Genomics. In 2016, Chicago Magazine named him to Chicago’s Top Cancer Doctors list for Medical Oncology. In 2017, he was elected by his peers to a three-year term on the board for The Society for Integrative Oncology.

Dr. Ahn recommends complementing conventional treatment plans with patient-preferred mind-body interventions to enhance immunity through innate biological pathways called “psychoneuroimmunology.” Research has shown that mind-body interventions enhance such conventional cancer treatments as surgery, chemotherapy or radiation therapy by improving dose tolerance and ability to complete therapy, quality of life and, in some studies, enhance cure rates.

“Ultimately, I joined CTCA® because they have been delivering for decades this type of integrative care to every patient that is seen here, and I’m excited for the unlimited possibilities we can build here by continuing to offer and further innovate this integrative approach,” says Dr. Ahn.

Licensed to practice medicine by the State of Florida and Illinois, Dr. Ahn is board certified in Medical Oncology, Infectious Diseases and Internal Medicine by the American Board of Internal Medicine.

He will also serve as CTCA Chicago's Medical Director for Clinical Research (in Integrative Oncology) to enhance the clinical research portfolio at CTCA. He has particular interest in studying the most active ingredients of an integrative oncology approach.

When he is not at CTCA, Dr. Ahn enjoys spending time with his wife and newborn girl, playing piano and guitar, and exploring the beautiful outdoors.

Patient ratings and comments

The patient ratings and comments on this page are obtained from an external Press Ganey® outpatient survey provided to all eligible CTCA patients within one to two weeks of their treatment occurrence. Raw data from the answers to the survey questions about our physicians are calculated by Press Ganey into a one- to five-star rating. In the spirit of transparency, all patient comments are posted as written by the patient, whether they are positive or negative. We only exclude comments if they are deemed to be slanderous or libelous, contain profanity or vulgar language, or do not relate to the patient’s experience with the doctor involved. As a result, the comments are the views and opinions of the patients surveyed and are not endorsed by, and may not necessarily reflect the opinion of, CTCA.

My favorite thing about my Oncologist is his patience. He does not seem in a rush, and always has given me time to address every issue I have had.

I am almost finished with my treatments. I have been pleased with Dr Ahn from the beginning. He has been concerned throughout, giving me the time I needed to make decisions and answering my questions ( I had many). I am very pleased with the treatment I have received from him. I haven't been the easiest patient and for the most part he kept his patience with me. I am grateful to have him as my doctor.

About our ratings Load More Comments

Press Ganey Data Integrity Certified

About our star ratings

The patient star ratings are an average of all responses to physician-related questions on our nationally recognized Press Ganey Patient Satisfaction Survey.

Cancer Treatment Centers of America® (CTCA) measures patient satisfaction as part of our effort toward continuous improvement in all aspects of the patient experience. We partner with Press Ganey®, a third-party-validated organization with over 30 years of experience supporting over 26,000 health care organizations, to survey our patients about their recent experiences at CTCA®.

Why is this information important?

CTCA is committed to transparency. Not only do the surveys allow us to continuously improve our services, but we hope these ratings will help you feel confident in your decision to seek care at CTCA.

How are the star scores calculated?

All eligible CTCA patients receive a survey from Press Ganey within one to two weeks after their treatment occurrence. In addition to being asked about their overall experience at CTCA, patients are asked to score the level of confidence they have in their provider, as well as the likelihood they will recommend the physician to others. Raw data from the answers to the survey questions about our physicians are calculated by Press Ganey into a one- to five-star rating, with one star being the lowest possible rating and five stars being the highest.

Are all comments included?

In the spirit of transparency, all patient comments are posted as written by the patient, whether they are positive or negative. Patients’ names and other identifying information are removed from the comments for confidentiality and patient privacy. We only exclude comments if they are deemed to be slanderous or libelous, contain profanity or vulgar language, do not relate to the patient’s experience with the doctor involved, or are statements that cannot be verified as factual. As a result, the comments are the views and opinions of the patients surveyed and are not endorsed by, and may not necessarily reflect the opinion of, CTCA. All ratings are included even if a comment is excluded.

Why don’t all physicians have ratings and comments?

Following industry best practice, star ratings and comments are only published for physicians with a minimum of 30 completed patient surveys. This helps us ensure that the sample size is large enough to give you an accurate representation of the physician's care.

Star ratings and comments are not available for all physicians or specialties. The validated Press Ganey survey captures patient experience feedback with the primary oncology services of chemotherapy and radiation therapy, which include only medical, radiation and in-office gynecologic oncology services. Gynecologic surgeries are not evaluated at this time because a different survey tool would be required.

Can anyone provide ratings and responses for a physician?

No. Only patients who are under the care of the physician can provide a response through the Press Ganey survey. Eligible patients receive the survey either by mail or email after their treatment occurrence. Survey responses are completely voluntary.

How do you protect patient information for those who have responded to the survey?

Patient privacy is of the utmost importance to us. If a review comment includes any information that could identify a patient (e.g., name, etc.), it is removed from the comment prior to publishing on the physician’s bio page. All patient information that has been removed from a comment is designated with an ellipsis, or “[…]”.

How often are the scores updated?

Press Ganey surveys are sent out all year long. All patient ratings and reviews are regularly updated and published within a month of receiving the responses. Ratings and reviews remain on a physician’s bio page for one year after being published. After that time period, the ratings and reviews older than a year are removed to ensure the most current information is available.
