Bilateral Mastectomies: a patient�s personal decision

September 08, 2014
Last week the Seattle Times reported that women diagnosed with early stage breast cancer in one breast are choosing to have bilateral mastectomies to reduce their chances of getting cancer again, but recent research shows that that there is no survival benefit, even in younger women. Researchers at Stanford and the Cancer Prevention Institute of California evaluated the outcomes of over 190,000 women from the California Cancer registry who were diagnosed with breast cancer in one breast between 1998 and 2011. The rate of bilateral mastectomies rose from 2% to 12.3% over the study period, yet there was no survival benefit to bilateral mastectomies versus lumpectomy and radiation.

To those of us who work in the field, this data comes as no surprise; the trend of bilateral mastectomies is a known phenomenon. More than 10 years ago, I remember the chatter among surgeons at national meetings asking if others noticed that more and more, younger women were coming in asking for bilateral mastectomies. ...

Reducing visits to the operating room for breast cancer patients

May 23, 2014

Swedish Cancer Institute has changed the way early stage breast cancer patients are cared for by adopting new surgical margin guidelines.  These guidelines will reduce the need for taking women back to the operating room if cancer cells are found at or near the specimen edge, also known as the margin. Following extensive review of the data, this new guideline was established by breast experts from the Society of Surgical Oncology and the American Society of Radiation Oncology and has been endorsed by the American Society of Breast Surgeons and the American Society of Clinical Oncology.
Many women with early stage invasive breast cancer opt for breast conserving surgery, known as lumpectomy or partial mastectomy. For 20-25% of these patients, a second surgery or re-excision was performed ...

Dr. Buchanan was very compassionate even though she knew I was seeking a second opinion & very clear about her treatment recommendation -
Swedish Patient

I appreciate Claire Buchanan's communication skills, as well as the medical care I received. She uses technology well and makes sure her notes are sent to my PCP as well as to me. She explains the pros and cons of treatment alternatives, makes recommendations and respects my final decision.
Swedish Patient

I have recommended her to others.
Swedish Patient

I already have recommended her.
Swedish Patient

Dr. Buchanan provided my care at this appointment. She was even the one who came out to the waiting room to call my name. She is so personable and explains everything in such a clear way. When I was concerned about my biopsies she even called the radiologist herself to explain my situation. I couldn't ask for a better surgeon to be on my team of care.
Swedish Patient

Dr. B. is the best! An excellent surgeon and a kind & caring human being.
Swedish Patient

Dr Claire Buchanan is one of the very finest surgeons and physicians in her field. She is supremely caring. I would trust her with my life. I am now five years out from cancer surgery and see her once a year. She always remembers details from our previous conversation and takes enough time to address my questions.

I felt a little rushed on the first appointment, but felt like the provider was willing to spend more time the second visit. She used pictures and words that helped with understanding the illness.
