Women over 40 would benefit from annual screening mammography

April 09, 2017

Of the 1,071 patients in the 40 ?? 49 age group with breast cancer, 373 were diagnosed as a result of screening. Of that 373, 39 percent had a family history of breast cancer, and 61 percent had no family history of breast cancer.  In the family history group, 63.2 percent of the patients had invasive disease, and 36.8 percent had noninvasive disease. In the no family history group, 64 percent of the patients had invasive disease, and 36 percent had noninvasive disease. The respective lymph node metastatic rates were 31 percent and 29 percent.

"In the 40 ?? 49 age group, we found a significant rate of breast cancer and similar rates of invasive disease in women with and without family history," Dr. Destounis said. "Additionally, we found the lymph node metastatic rate was similar."

According to Dr. Destounis, these results underscore the importance of early detection and annual screening mammography for women between the ages of 40 and 49 whether or not they have a family history of breast cancer.
