I'm glad to hear your mom is doing well on tarceva; and that she is still able to work. How many mlg. Is she taking? I'm on 150mlg. And will be continuing on that dose for at least another four weeks. Depending on the results of my ct scan will determine weather i will continue on tarceva, or pursue another treatment. I'm hoping the results of the ct scan will be promising so i can continue with the tarceva, as i've heard so much good news regarding this chemotherapy drug. Many blessingPalma
