Ethnic Breast Cancer?

New research provides more explanation as to why more black women die of breast cancer than white women, despite the evidence of breast cancer incidence being higher among white women.

According to LA BioMed investigator Rowan Chelbowski, M.D, Ph.D., results of the study show a significantly lower breast cancer incidence among black women. However, while they were less likely to develop the illness, they were also less likely to survive it. Dr. Chelbowski says: "Ethnicity had a major effect on poor prognosis cancer risk. In black women, a higher proportion of breast cancers are diagnosed with unfavorable characteristics."

Dr. Chelbowski points out that genetic and biochemical factors may be the source for those high-grade, receptornegative cancers. He points out that, "Black women might have a genetic profile that puts them at lower risk of getting breast cancer, but higher risk of this one specific high-grade tumor."

A Periodic Table For Biology

In the June 21st edition of The Scientist, Dr. John Torday presents a stimulating case for a periodic table for biology, much in the same way that Mendeleev imparted order to the chemical elements.

According to Dr. Torday: "Like the chemical elements, human genome data behooves biologists to systematize information and view it through a new lens The gene pools of contemporary species have evolved not by chance, but through the process of natural selection. Therefore, we should be thinking about how to exploit this process in order to discern gene-selection patterns based on function, that is, through functional and comparative genomics."
