Estimating Breast Cancer Risk (cont.)
8. How did BCPT and STAR use the Breast Cancer Risk Assessment Tool to add
to our knowledge of breast cancer risk?
Both breast cancer prevention studies, BCPT and STAR, explored ways of
reducing the risk of developing breast cancer; their findings have increased our
knowledge of risk. Both trials involved women who have not had breast cancer,
but were at high risk of developing it. BCPT used the Breast Cancer Risk
Assessment Tool to determine eligible participants by projecting each woman's
individualized estimate of breast cancer risk. The projections were accurate;
thus the BCPT results validated the Breast Cancer Risk Assessment Tool. STAR
researchers used the Breast Cancer Risk Assessment Tool for determining
eligibility for enrollment. All STAR participants had to have an increased risk
of breast cancer equivalent to or greater than that of an average 60- to
64-year-old woman.
9. What else can a woman do about breast cancer?
NCI recommends that women in their 40s and older get screening mammograms
every one to two years. Women who are at higher than average risk of breast
cancer should talk with their health care providers about whether to have
mammograms before age 40 and how often to have them. Women also can take an
active part in the early detection of breast cancer by having regular clinical
breast exams (breast exams performed by health professionals).
Advances in screening have provided new tools for detection. In September of
2005, preliminary results from a large clinical trial of digital vs. film
mammography found no difference in detecting breast cancer for the general
populations of women in the trial. However, the Digital Mammographic Imaging
Screening Trial (DMIST) found that women with dense breasts, who are pre- or
perimenopausal (women who had a last menstrual period within 12 months of their
mammograms), or who are younger than age 50, may benefit from having a digital
rather than a regular film mammogram. More information about DMIST can be found
