New studies exploring breast cancer risk perceptions and use of radiotherapy and MRI for women with ductal carcinoma in situ (DCIS, a preinvasive form of breast cancer) were highlighted today in a virtual presscast in advance of the 2013 Breast Cancer Symposium. The Symposium will take place September 7-9, 2013, at the San Francisco Marriott Marquis in San Francisco.
Three major studies were highlighted in today's presscast:
Radiation therapy for DCIS is safe, and does not appear to increase the risk of developing or dying from cardiovascular disease: A population-based study conducted in the Netherlands found that cardiovascular disease incidence and mortality rates among DCIS survivors ten years after completion of radiation therapy were similar to those of the general population of Dutch women.
MRI around the time of surgery may be unnecessary for women with DCIS: A large, retrospective study of women who underwent a lumpectomy for DCIS found that adding an MRI scan to standard mammography immediately before or after surgery does not decrease locoregional recurrence rates.
A large survey suggests majority of women may have an inaccurate perception about their personal breast cancer risk: An analysis of survey data collected from nearly 10,000 Long Island, New York, women who were scheduled to undergo mammography screenings determined that roughly one in ten women had an accurate perception of her lifetime risk of developing breast cancer. Additionally, less than half of women said they had ever discussed breast cancer risk with their doctor.
