Cancer Research: Orange lichens are potential source for anticancer drugs ♦ Alcohol intake increases the risk of breast cancer ♦ Studies point to clinical advantages of proton therapy

Discovery opens door to new strategy for cancer immunotherapy Scientists raise the prospect of cancer therapy that works by converting a tumor's best friends in the immune system into its gravest enemies. The team has uncovered a mechanism that allows key immune system cells to keep a steady rein on their more belligerent brother cells, thereby protecting normal, healthy tissue from assault. The discovery has powerful implications for cancer immunotherapy.
Studies point to clinical advantages of proton therapy New data from clinical trials demonstrate the technology's potential advantages over conventional radiation, including less side effects and survival in some cases, for several harder-to-treat tumors: pancreatic, late-stage, non-small cell lung and chordoma and chondrosarcoma, two rare cancers found in bone or soft tissue.
Orange lichens are potential source for anticancer drugs An orange pigment found in lichens and rhubarb called parietin may have potential as an anti-cancer drug because it interferes with the metabolic enzyme 6PGD.
Test could predict whether breast cancer will spread to the brain Women with particularly aggressive forms of breast cancer could be identified by a test that predicts whether the disease is likely to spread to the brain. An analysis of almost 4,000 patients with breast cancer found that testing for high activity in a particular gene could pick out women who were at greater risk of developing secondary brain tumors compared to women who tested negative.
Alcohol intake increases the risk of breast cancer Saying that the link between alcohol and cancer is dangerous is nothing new. Five Spanish universities and more than 300,000 female volunteers participated in a European investigation that is now confirming that alcohol intake increases the chances of developing breast cancer. This risk quadruples with the intake of each daily glass of wine or beer.
