I believe that the care of every patient should be tailored to his/her disease process, other medical conditions, and goals of treatment. My philosophy is to provide multidisciplinary care that offers patients all available options, including the most recent treatment advances and participation in clinical trials. The end result is an individualized treatment plan that addresses the disease but also values each patient’s unique perspective regarding care.


Dr. Yen joined the Medical College of Wisconsin in 2004, after completing her surgical oncology fellowship at the University of Texas M.D. Anderson Cancer Center. Her clinical practice is devoted solely to patients with breast cancer and tumors of the endocrine system (thyroid, parathyroid and adrenal gland). She is the Service Chief for Breast and Endocrine Surgery at Froedtert Hospital.

Dr. Yen’s research program is also devoted to breast cancer and endocrine surgery. Her funded breast cancer health services research is focused on quality of care, patterns of care and the relationship of these patterns of care to outcomes of care. Her research has examined lymphedema (arm swelling) after breast cancer treatment, processes of breast cancer care, and adoption of sentinel lymph node biopsy. Dr. Yen is also active in clinical trials and is the institutional principal investigator for the Alliance for Clinical Trials in Oncology, a national clinical trials network sponsored by the National Cancer Institute (NCI).

Dr. Yen is a fellow of the American College of Surgeons, and a member of the editorial boards of Annals of Surgical Oncology and Surgery.  She holds several national leadership positions, including Recorder for the Central Surgical Association, editorial board member for the Surgical Council on Resident Education, and member of the American College of Surgeons Advisory Council for General Surgery.

doctor was brought in last minute and was brought up to speed very quickly.

Worst communication I have ever had with a physician. If she did not think surgery was a good option she should have said so with reasoning. I had to ask her many questions to get to that conclusion. It made whole interaction very uncomfortable and felt misguided. I felt like I had to ask questions and put all the pieces together. Would been easier if she just stated her opinion upfront and gave reasoning.

Everyone acted like they were happy to work there. It made me feel at ease. I didn't feel like an annoyance to them.

Dr. was easy to understand and I enjoy learning about my condition with her.

I felt very included, in any decisions that needed to be made, and was able to do that because of the info given by the doctors. Everyone, from the person that checked me in for surgery, to the many nurses, doctors and staff, all seemed to like what they did and it showed in their care.

My respect and appreciation for Dr Tina Yen could not be higher. The confidence and knowledge with which she approached my cancer made me less fearful I appreciated that she just knew w hat was best and trusted her fully. This is my second surgery with her in roughly a one year period. I will never be able to thank her enough. if I had to change one thing, I would say that it was not beneficial to have the "teaching" appointment the day before my surgery. I was unable to get any proper clothes or items I needed to care for my drains in time for the surgery.

I especially appreciated Dr. Yen's vitae, the respect for my own intelligence, the laser focus on my face which helped me hear better ( I wear aids) and feel I was the center of attention for my doctor. she discussed important complications of treatment and options, convincing me of her attention to care. I had come for a second opinion and everything and everyone at the cancer center convinced me to switch my care to Froedert despite a 45 minute commute from whereI live 5 min. away from an Aurora Cancer Center.

1.very explicit in stating my options,2. repeated my options more than once so I clearly understood what was needed,3. friendly, 4.organized all other doctors that I would need to see, 5.showed me test results (pictures) with a brief but clear summary of the results. We (my husband, daughter and myself) were truly impressed with her professionalism. She spent a lot of time with us and we left her office feeling that we picked the right doctor.
