The farther away a woman lives from a radiation therapy facility, the less likely she is to get lumpectomy with adjuvant radiation therapy for early stage breast cancer, and may instead get mastectomy, according to a new study. Published in the January 1, 2006 issue of CANCER, a peer-reviewed journal of the American Cancer Society, the study reveals that being older, of Hispanic origin, or unmarried at diagnosis were also associated with decreased likelihood of treatment with lumpectomy and radiation therapy, and that both geographic accessibility and affordability of insurance influenced womens cancer treatment.
Mastectomy – a one-time surgery to remove all breast tissue along with the tumor – was once the only treatment option for women with early stage breast cancer. Breast-conserving surgery with radiation (BCSR) has been shown to be just as effective as mastectomy in terms of long time survival, but requires multiple follow-up visits for the radiation therapy. Despite professional recommendations that--unless there are contraindications--BCSR is the standard of care for localized breast cancer, studies show that women, particularly the elderly, ethnic minorities, and the uninsured, are less likely to receive BCSR. The conclusion often made is that affordability affects the receipt of BCSR. Studies of other cancers also implicate travel distance as a factor in access to treatment.
To determine whether travel distance from home to a radiation facility is an independent factor predicting BCSR use, Lydia Voti, DSc of the University of Miami and her colleagues reviewed inpatient and outpatient data for 18,903 breast cancer cases in Florida treated with BCSR or mastectomy.

Astronomers from Bonn and Tautenburg in Thuringia (Germany) used the 100-m radio telescope at Effelsberg to observe several galaxy clusters. At the edges of these large accumulations of dark matter, stellar systems (galaxies), hot gas, and charged particles, they found magnetic fields that are exceptionally ordered over distances of many million light years. This makes them the most extended magnetic fields in the universe known so far.
The results will be published on March 22 in the journal „Astronomy & Astrophysics“.
Galaxy clusters are the largest gravitationally bound structures in the universe. With a typical extent of about 10 million light years, i.e. 100 times the...
Researchers at the Goethe University Frankfurt, together with partners from the University of Tübingen in Germany and Queen Mary University as well as Francis Crick Institute from London (UK) have developed a novel technology to decipher the secret ubiquitin code.
Ubiquitin is a small protein that can be linked to other cellular proteins, thereby controlling and modulating their functions. The attachment occurs in many...

Silicon nanosheets are thin, two-dimensional layers with exceptional optoelectronic properties very similar to those of graphene. Albeit, the nanosheets are less stable. Now researchers at the Technical University of Munich (TUM) have, for the first time ever, produced a composite material combining silicon nanosheets and a polymer that is both UV-resistant and easy to process. This brings the scientists a significant step closer to industrial applications like flexible displays and photosensors.

Enzymes behave differently in a test tube compared with the molecular scrum of a living cell. Chemists from the University of Basel have now been able to simulate these confined natural conditions in artificial vesicles for the first time. As reported in the academic journal Small, the results are offering better insight into the development of nanoreactors and artificial organelles.
