Cervix Moves Significantly More Than Previously Thought During Radiation for Cancer

Please read article, cited after the quote. Articles open in a new window.

Radiation and gynecologic oncologists at the Moores Cancer Center at the University of California, San Diego are concerned that many women with cervical cancer may not be receiving the optimal dose of radiation during treatments specific for the shape of the tumor because the cervix may be moving too much.  They recommend that radiation oncologists need to take such movement into account to make sure the cervix remains in the treatment field.

The team presented its findings – the first to look at cervix movement during radiation therapy – on February 6, 2009 at the Society of Gynecologic Oncologists’ 40th Annual Meeting on Women’s Cancer in San Antonio.

The researchers found that the cervix moved significantly more than previously thought during radiation therapy, possibly affecting treatment. As a result, radiation oncologists may have to spare less healthy tissue than they would like to effectively treat the cancer.
