Unchanged since 1996, Sweden's hexavalent chromium exposure limit is higher than in several other countries. A research study from Lund University in Sweden shows that even workers exposed to levels of chromium below the Swedish limit display significant cell changes long before cancer develops. A proposal from the Swedish Work Environment Authority to lower the limit has now been put forward.

A team of researchers developed a novel tool to help understand consumer behavior at the county level, and to study the relationship between where people shop for their food and the risk of obesity-related cancers. Their findings are published in BMC Medicine.

CNIO researchers discover that, in mice that eat a lot of fat, cancer cells travelling through the blood surround themselves with platelets, which act as an armor-like protection as they spread.

In addition, in animals with a fatty diet it is easier for tumor cells to 'nest' in other organs and give rise to metastasis of the primary tumor.

 “These results anticipate a future in which dietary changes, together with the control of platelet activity, will complement antitumor treatments,” says Héctor Peinado, of the Spanish National Cancer Research Center (CNIO).

The study is published in 'Nature Communications’.
