A worrisome report on breast cancer trends in the U.S. appeared on-line today, ahead of print in an AACR journal, Cancer Epidemiology, Biomarkers & Prevention.
The analysis, based on the NCI’s SEER data from 2000 — 2007, shows that the incidence of breast cancer in the U.S. is no longer declining. (A drop after 2002 in BC incidence is generally attributed to an abrupt reduction in HRT around that time.)
Since 2003 the overall BC rate has been steady overall, with a few exceptions:
The incidence of BC in non-Hispanic white women ages 60–69 rose by 4.8% in this period. “It remains to be seen if this trend will continue,” according to the study authors.
Among white women ages 40–49 rates of estrogen receptor (ER) positive (ER+) breast cancer significantly increased by an average of 2.7% per year during this period. In contrast, the rate of ER– breast tumors decreased, overall, although
