Breast Cancer Surgery Often Repeated To Take Out More Tissue
22.9% of breast cancer patients who undergo partial mastectomies need further operations to remove more tissue, researchers reported in JAMA (Journal of the American Medical Association). The authors, from Michigan State University, added that rates of reexcision vary considerably between surgeons and clinics/hospitals; this variation does not appear to be caused by patients' clinical characteristics. "Excision" means the surgical removal of something, which in this text means a tumor. "Reexcision" means additional surgery in the same area.

ONCOLOGY: Answers to age-old questions surrounding fat cell cancer Myxoid round cell liposarcoma (MRCLS) is a cancerous tumor that typically arises in deep fat tissues of the limbs or abdomen. It was shown almost 20 years ago to be characterized by a chromosomal change that generates a fusion protein known as TLS:CHOP. Despite this, neither the cell from which MRCLS arise nor the mechanism(s) by which TLS:CHOP induces tumor formation have been definitively determined. A team of researchers led by Igor Matushansky, at Columbia University, New York, has now provided some answers to these questions;
Recommended Breast Screening MRI Not Followed Through
A study of 64, 659 women, recently published in the journal Academic Radiology, found that while 1, 246 of these women were at high enough breast cancer risk to recommend additional screening with MRI, only 173 of these women returned to the clinic within a year for the additional screening. "It's hard to tell where, exactly, is the disconnect, " says Deborah Glueck, PhD, investigator at the University of Colorado Cancer Center and associate professor of biostatistics and informatics at the Colorado School of Public Health, the paper's senior author.
