Five per cent of breast cancer tumors appear to double in size in just over a month, researchers said yesterday.
The study, in the journal Breast Cancer Research, also suggested detection rates of just 26% for a 5mm tumor and 91% for a 10mm tumor. The computer data was from nearly 400,000 women aged 50 to 69. The faster growth was mainly among younger women in the study’s age group. (Daily Telegraph, 9/5/08, p25; Adelaide Advertiser, 9/5/08, p37)

A University of Washington study claims that fetal cells surviving in a mother’s tissues may fight off breast tumors, perhaps explaining why women with children have a lower risk of getting breast cancer than childless women. Researcher V.K. Gadi presented the findings of the controlled study in San Diego last month. (New Scientist, 8/5/08, p10.)

Adult women who were breast-fed as infants may have a lower risk of developing breast cancer than those who were not breast-fed, unless they were first-born, study findings suggest. “As a general group, women who reported they had been breast-fed in infancy had a 17 percent decrease in breast cancer risk,” Hazel B. Nichols, who was involved in the study, told Reuters Health. (Epidemiology, May 2008)

A meta-analysis of studies of taxanes alone or in combination with anthracyclines as first-line therapy for patients with metastatic breast cancer shows that neither approach provides a survival advantage. (J Clin Oncol, Reuters Health May 9, 2008;26:1980-1986.)

Adding screening ultrasonography to conventional breast mammography increases the diagnostic yield by about 50% among women at high risk for breast cancer, according to study findings published in the Journal of the American Medical Association for May 14. However, the combined strategy also substantially increases the number of false positives. (JAMA 2008;299:2151-2163,2203-2205).
