(Weizmann Institute of Science) In two complementary studies, Weizmann Institute scientists have developed a new method for reconstructing a cell's 'family tree,' and have applied this technique to trace the history of the development of cancer.

So far, the scientists have been able to calculate the age of the tumor and characterize its growth pattern.

The scientists believe cell lineage studies of cancer can eventually lead us to the root of cancer.

HOUSTON -- The tumor-derived vaccine vitespen (Oncophage) does not prevent kidney cancer recurrence or improve survival despite promising early results, researchers said.

(Journal of Experimental Medicine) Tumors escape destruction by immune cells by turning off their tumor killing functions.

A team of scientists in the UK have now found a way to retrain the impotent cells into potent tumor destroyers.

Their study will be published online May 19 in the Journal of Experimental Medicine.
