Breast cancer linked to bacteria

By comparing the genes of those diagnosed with the condition with those who had no history of breast cancer, the researchers were able to identify 65 variations of genes that contributed to the disease's development.

Dr Pallave Dasari, an Australian breast cancer research fellow at University of Adelaide, said that while she believed this was a "really valuable" progression in understanding family history risk, a test was "extremely premature" at this stage.

Yet breast cancer is still one of the most deadly forms of cancer for many women in the USA, coming second only to lung cancer for some demographic groups.

Crestwood Medical Center and WDRM teamed up for a breast cancer awareness concert Monday night.

"Scientists are not in competition against each other", said professor Peter Kraft of Harvard T.H. Chan School of Public Health.

The new studies, published in the journals Nature and Nature Genetics, underscored the fact that the two cancer types are biologically distinct and develop differently.

"We knew about 100 before, it is a big contribution but probably more important than the number is the methods we developed", she said.

While 41 percent of those receiving conventional treatment for lung cancer survive for at least five years, only 20 percent of those opting for alternative medicines do so, the research adds.

'But we have no evidence that anyone benefits from these diets, apart from those that collect the fees'.

By analysing the 180 regions of the genome where are located some of the variations that predispose to breast cancer, it will be possible to determine the risk of a woman developing this cancer.

The combined effect of these variants is likely to be "considerable" said the researchers. Dr. Eng says the next step is to look at whether they could target the bacteria that is specifically in the breast cancer tissue with treatment, or even better, pinpoint the problem area and target it before the breast cancer has a chance to develop.

"Many women are offered mammogram screening when they are middle-aged, but if we know a woman has genetic markers that place her at higher risk of breast cancer, we can recommend more intensive screening at a younger age", says Chenevix-Trench.

'These gene changes now have the potential to be incorporated into existing models to more accurately predict an individual's risk, and to improve both prevention and early detection of the disease.

In 2017, it is estimated that 17,586 women and 144 men will be diagnosed with breast cancer, according to Breast Cancer Network Australia.
