Genetic link between mammographic density and breast cancerA University of Melbourne study has revealed that certain breast cancer genetic variants increase mammographic density, confirming the link between mammographic breast density and breast cancer.
Professor John Hopper of the University's School of Population Health says women vary greatly in their underlying risk of breast cancer. "These findings provide an insight into possible new pathways into the development of breast cancer".

Bowel disease link to blood clotsPeople living with Inflammatory Bowel Disease (IBD) are known to be at high risk of blood clots when admitted to hospital during a flare-up of their disease but now new research by researchers at The University of Nottingham has shown that those who are not admitted to hospital during flare-ups are also at risk.

Killing cancer with nanoUsing lasers and nanoparticles, researchers at Rice University have discovered a new technique for singling out individual diseased cells and destroying them with tiny explosions. The researchers used lasers to make "nanobubbles" by zapping gold nanoparticles inside cells. In tests on cancer cells, they found they could tune the lasers to create either small, bright bubbles that were visible but harmless or large bubbles that burst the cells.
