PSA Screening Does Not Help Mortality
A study published in the Journal of the National Cancer Institute reveals that there is no difference in mortality rates between men participating in the Prostate, Lung, Colorectal and Ovarian Cancer (PLCO) Screening Trial, and men who receive usual care after 13 years follow-up. In November 1993, the multi-center, two-arm, PLCO Trial, began enrollment with follow-up, through December 2009. The trial assessed the effect of screening on prostate, lung, colorectal, and ovarian cancer. Participants had no previous history of these cancers and were aged between 55 and 74 years of age.
Device Provides A Platform For Viewing Cancer Cells And Other Macromolecules In Dynamic, Life-Sustaining Liquid Environments
A photograph of a polar bear in captivity, no matter how sharp the resolution, can never reveal as much about behavior as footage of that polar bear in its natural habitat. The behavior of cells and molecules can prove even more elusive. Limitations in biomedical imaging technologies have hampered attempts to understand cellular and molecular behavior, with biologists trying to envision dynamic processes through static snapshots. Deborah Kelly, an assistant professor in the Virginia Tech Carilion Research Institute, has now developed a novel technology platform to peer closely into the world of cells and molecules within a native, liquid environment.
Alcohol Consumption And Risk Of Colon Cancer In People With A Family History Of Such Cancer
A study based on more than 87, 000 women and 47, 000 men in the Nurses' Health Study and the Health Professionals Follow-up Study, looks at whether there is a link between colon cancer and alcohol, and if so at what level of consumption, and the importance of a family history of the disease. A total of 1, 801 cases of colon cancer were diagnosed during follow-up from 1980 onwards. The authors results found that subjects with a family history, whose average alcohol intake was 30 or more grams per day (about 2 В typical drinks by US standards or 4 UK units) had an increase in their risk of colon cancer.
