Dr. Janet S. Rader is currently the Jack A. and Elaine D. Klieger Professor and Chair of the Department of Obstetrics and Gynecology. She received her medical degree from the University of Missouri in Columbia, Missouri and completed her residency in Obstetrics and Gynecology at Michael Reese Hospital and Medical Center in Chicago, Illinois. She then served as a Research Fellow in the Department of Molecular Genetics and Cell Biology, Howard Hughes Medical Institute at the University of Chicago. Dr. Rader completed a fellowship in Gynecologic Oncology at Johns Hopkins University, Baltimore, Maryland.


Dr. Rader has been a continuous recipient of NIH and ACS funding since 1994. Her research work is in early molecular changes in cervical cancer and genetic predisposition. She is on the steering committee of The Cancer Genome Atlas (TCGA) for ovarian cancer and the NCI Cervical Cancer Task Force. She is a member of the Cancer Prevention and Control Committee and the Committee on Experimental Medicine of the Gynecologic Oncology Group. Dr. Rader is associate editor for Cancer Epidemiology, Biomarkers & Prevention and has authored or co-authored 139 peer-reviewed articles. She is PI for several clinical trials in gynecologic malignancies. She is a member of many organizations, including: The Society of Gynecologic Oncologists, The American Society of Clinical Oncology, The American Association for Cancer Research, and The American Society of Human Genetics.


Her laboratory focuses on advancing cervical cancer prevention and control. Infection with high-risk human papillomavirus (HPV) is the primary inciting event, but it is evident that additional factors must be involved, since only a small proportion of infected women develop cancer. The laboratory concentrates on identifying genes involved in the progression of cervical cancer through the analysis of molecular changes in preinvasive and invasive neoplasias of the cervix, in addition to identifying host genetic susceptibility polymorphisms in the progression of disease.

Dr Rader and her nursing team are fabulous. they are knowledgeable - not just about my disease generally, but about the specifics of my case. They are also interested in my thoughts and ideas about treatment and thoughtfully answer my questions. The relationship we have forged over the course of the last nearly 6 years of treating my recurrent cancer has been life-giving.On the other hand, the schedulers are absolutely horrible. I don't know what changes have been made in the last couple of months to the way scheduling is handled, but please change everything back. As I undergo treatment, I am having appointments for labs, Dr Rader, and chemo every 3 weeks. Of the 5 appointments I am having from November through January, every single one has been handled incorrectly. It's enough to make me consider transferring my care to the UW hospital. If it weren't for Dr Rader, I would be pursuing that change now due to the incompetence of the scheduling staff at Froedtert. Please address this soon.

Just finished chemotherapy in October and this was a visit with six week test results following completion of that and discussion of what comes next. Some questions did not exactly fit my situation but feel I received excellent care.

Additional health issues occurred, DVT, since my last appointment, involving another medical facility. After 2 months of uncertain direction from the secondary facility, Dr. Rader, affirmed the choices that I was already considering. I felt assured that I was on the right track.

She and everyone involved acknowledged and respected that I am the person who needs to make these decisions regarding my treatment, while giving me useful, up-to-date information that would help me choose based on available knowledge.

Dr. Rader is an excellent physician! She is as gentle and understanding and acutely aware of the patient's feelings in all respects. I would not hesitate to make any future appointments as needed with her. She helped to overcome my fear of gynecologic tools. Thank you Dr. Rader!!!!!

Dr. Rader went beyond other doctors' visits in recommending PT/OT for lymphedema.

My provider and staff were courteous, respectable and compassionate.

Dr. Rader is an amazing doctor and I can tell she cares so much about all of her patients. Sometimes I feel a little rushed and that I have to spit out all of my questions at once since I know she is so busy and probably has stuff to do. I forgot to ask a question that I wanted to. but she sat down and let us ask questions and explained things very well. She also greatly remembered me and little details about me which is really cool. She made me feel comfortable during examination and took time to talk to my mom as well.

I have no complaints about Dr. Rader's care; however, I have one complaint about the nurse who spoke with me before Dr. Rader saw me. Although she was very kind and courteous, she stated Dr. Rader would talk to me about "the plan." As I was waiting to hear news on whether I had a potential malignancy, this word choice led me to believe that they already thought it was one, and required a "plan." This caused me unnecessary anxiety as I waited the next 15-20 minutes until Dr. Rader came in to explain that it was not a malignancy. I don't know whether or not this nurse was aware of Dr. Rader's impressions of my condition, but it would have been less nerve-wrecking if she had just said "talk about the details" or some other phrase that didn't have frightening implications. This probably wouldn't be a huge problem for most people, but for me it just put me more on edge than I needed to be at that time.

Dr. Rader is a very attentive listener and provides adequate time for thorough communication between patient and staff. She is top notch in her attention to detail and concern for the patient as well as finding the best treatment for each individual. I highly recommend her.

Dr Rader is very easy to talk to. She takes the time to explain things so I know how to make decisions.

After 6 years of treatment, I was released from care, but told to repeat blood work in 3 months because of elevated levels.
