'Microtentacles' on tumor cells appear to play role in how breast cancer spreads

Researchers have discovered that "microtentacles," or extensions of the plasma membrane of breast cancer cells, appear to play a key role in how cancers spread to distant locations in the body. Targeting these microtentacles, which are linked to a protein called "tau," might prove to be a new way to prevent or slow the growth of these secondary cancers, the scientists say.
