WASHINGTON, D.C. July 24, 2009 -- Half of all Americans will be diagnosed at some point in their lives with cancer, the number two killer in the United States. One of the most common types, especially among women, is breast cancer. According to the National Cancer Institute, 192,370 women will be diagnosed with breast cancer in 2009, and more than 40,000 women will die from the disease this year alone.
One of the professions at the frontlines in the battle against breast cancer is medical physics. Medical physicists help to develop new imaging technologies and improve existing ones. They devise new therapeutic techniques, and they create methods to assess the safety and effectiveness of treatments that are already in use.
Included below are highlights of a few of the presentations related to breast cancer research at the 51st annual meeting of the American Association of Physicists in Medicine (AAPM), which takes place from July 26 - 30 in Anaheim, CA. Registration information for journalists can be found at the end of the release.
A NEW SCREENING TOOL FOR BREAST CANCER
Mammography has proven to be very effective at lowering mortality related to breast cancer, but it does not work equally well in all women. It frequently misses tumors that are there at the time of screening -- particularly in women who have dense breast tissue that can hide tumors from doctors. The National Cancer Institute reports that mammograms miss up to 20 percent of breast cancers that are present at the time of screening. Doctors often recommend women with dense breasts undergo magnetic resonance imaging (MRI), which is more expensive but better at detecting cancer in dense tissue.
Now doctors at the Mayo Clinic in Rochester, MN have developed a less expensive "molecular imaging" technique for detecting cancer in dense breast tissue using radioactive tracers. In Anaheim, Michael O'Connor, a professor of radiologic phys
