Cancer Treatment Centers of America at Midwestern Regional Medical Center (Midwestern) boasts holistic cancer care including advanced conventional treatment options and innovative complementary treatments under one roof. This facility is equidistant between Milwaukee to the north and Chicago to the south. Upon entering, you will check in and soon meet with your Nurse Navigator. Next to the new patient check-in area is the "Tree of Life." Each leaf on the tree displays the name of a CTCA cancer survivor who has reached his or her five-year anniversary of being cancer free.
