Welcome to the Illinois Medical Oncology Society

Illinois Medical Oncology Society (IMOS)

Formed on July 29, 1989, the Illinois Medical Oncology Society (IMOS) represents the common interests of a majority of the oncologists treating cancer in Illinois. As the oncology society in Illinois, we strive to provide our members with innovative resources to help them stay ahead of the shifting healthcare landscape and challenges that directly impact the high-quality care their patients deserve.

The Illinois Medical Oncology Society now offers FREE  memberships to oncologists and allied oncology professionals.

The IMOS board would also like to hear from you (all levels and types of members and potential members) about things you’d like to see for 2019 - 2020 and how we can best serve your needs.

We are a State Affiliate of the American Society of Clinical Oncology.

Our Mission

We strive to promote the highest professional standards of oncology in the State of Illinois.  We create educational experiences for our members to exchange information to increase the quality of care for our patients. We act as a patient advocate to assure that patients have access to the best available care; and support and encourage clinical research against cancer.

IMOS joined with ASCO recently in support of Senate Bill 2499, which would guarantee coverage of the routine care costs for clinical trials participation for Medicaid enrollees in Illinois.  Read the joint letter sent to the bill sponsor, Senator Andy Lamar, here.

As you are aware, we are facing uncertain times with the emergence of the COVID-19 virus. There is nothing more important to us than the safety and well-being of our attendees’ and the patients they serve. After discussion among our board, we believe the best option moving forward is postponing the March 27th Spring Meeting. A rescheduled date will be selected soon but may remain tentative based on COVID-19 restrictions. We realize this may cause some inconvenience to you and we sincerely apologize!

Looking ahead, we are hopeful you'll still be able to join us. As it becomes available, additional information will be posted on our website.

Stay healthy and safe,

Carol Christner
Executive Director
