About me

Dr. Yajnik is the Medical Director and primarily practices at Advocate Illinois Masonic Medical Center. He attended both college and medical school at the University of Chicago and did his residency training at the Memorial Sloan-Kettering Cancer Center in New York. Dr. Yajnik has conducted research in the areas of prostate brachytherapy, radiation therapy for thoracic tumors, and gene therapy for prostate cancer. He has written numerous papers and made presentations locally and nationally. In 2004, his research on prostate brachytherapy was presented at the American Brachytherapy Society meeting in Barcelona, Spain.  In both 2005 and 2010, Dr. Yajnik has served as an American Society for Therapeutic Radiology and Oncology (ASTRO) representative on the collaborative subcommittee that revised the guidelines “ACR Practice Guidelines for the Performance of Stereotactic Radiosurgery”.  Dr. Yajnik served on the ASTRO Information Technology Development & Resource Committee in 2008-2009 and served on the ASTRO Communications Committee in 2009-2010.  Dr. Yajnik has been in private practice with Radiation Oncology Consultants since 2004.

Dr. Yajnik is trained in the use of 3-dimensional conformal radiation therapy, intensity modulated radiation therapy (IMRT), stereotactic radiosurgery, high dose rate brachytherapy, intraoperative radiation therapy, and permanent interstitial brachytherapy (seed implants). He has interest in treating a broad range of cancers including lung, genitourinary, breast, head and neck, central nervous system, and gynecologic malignancies.

When asked why he chose radiation oncology, he states, “Since my earliest patient interactions in medical school, I have felt a closeness and respect for my cancer patients. I became a radiation oncologist because I believe that radiation therapy is one of the most technologically advanced means of treating cancer. I believe that radiation oncology, in combination with molecular targeted therapies, will transform the way that we regard cancer, and help patients get back to living their lives.”
