In what is believed to be the largest study of its kind in the US, researchers have found that almost 26 percent of women studied who have breast cancer have mutations in a gene important in controlling cell growth and death, and that patients with mutations in this gene - known as p53 - had poorer outcomes including a significantly increased risk of death from the cancer.

New biomarker may predict leukemia aggressiveness

Scientists at the University of California, San Diego and the Moores UCSD Cancer Center have evidence of a potential new biomarker to predict the aggressiveness of an often difficult-to-treat form of leukemia. They found that high levels of a particular enzyme in the blood are an indicator that chronic lymphocytic leukemia (CLL) - the most common form of adult leukemia - will be aggressive and in...

The data were presented at the AACR 100th Annual Meeting 2009 in Denver.

Atmospheric lead causes clouds to form more easily, could change pattern of rain and snow

(PhysOrg.com) -- By sampling clouds -- and making their own -- researchers have shown for the first time a direct relation between lead in the sky and the formation of ice crystals that foster clouds. The results suggest that lead generated by human activities causes clouds to form at warmer temperatures and with less water. This could alter the pattern of both rain and snow in a warmer world.

Brain metastases hijack neuron-supporting cells to resist chemotherapy

Cancer that spreads to other organs finds a particularly inviting hideout in the brain, where these metastases are usually far harder to treat than they are in other locations. Two researchers from The University of Texas M. D. Anderson Cancer Center discussed ways to more successfully target these tumors in their "sanctuary" at the American Association for Cancer Research 100th Annual Meeting...
