Tarceva

We've received many emails from people wondering how Tarceva works, so we thought we would post it online for everyone to read:

Many different types of cancer cells, including non-small cell lung cancer, have a "receptor" on their surfaces called the "epidermal growth factor receptor." This receptor receives signals that tell the cancer cells to grow and multiply. Tarceva works by blocking this receptor and depriving the cancer cells of these signals.
