My husband, techno/science geek that he is (and I mean that in a
very loving way), just sent me this. The first two lines had me
thinking that he was spamming me, but the content is actually pretty
interesting, and the source seems quite impeccable.

How green tea can combat cancer

THE secret of green tea's anti-cancer properties has been uncovered.

Numerous studies suggest that green tea helps protect against a
range of cancers, including lung, prostate and breast cancer. This
has been attributed to an antioxidant called epigallocatechin
gallate (EGCG). Now Hirofumi Tachibana's team at Kyushu University
in Japan has shown that EGCG inhibits tumour cell growth by binding
to a receptor on cells called 67 LR. A variety of tumours produce
abnormally high levels of 67 LR, and the receptor is thought to be
involved in the spread of cancers through the body.

As part of the work, the team showed that the growth of human lung
cancer cells that have the receptor slows significantly when they
are exposed to EGCG at the concentrations reached in the body after
drinking just two or three cups of green tea (Nature Structural and
Molecular Biology, DOI: 10.1038/ nsmb743).
