I had a big brain met over a year after I started Tarceva. As I was reading the Bible each mornimng, I noticed my reading was getting bad because it looked like small drops of mercury were on the word I was reading. An MRI showed a big 5cm met under the back of my brain. It was removed with some sight impairment just in the nick of time, and was followed by radiation. I had a brain met that got me dianosed on the front part of my brain three years ago. Hang in there and fight the big C. Life can be good while living with Cancer.
Your tip about Tarceva not working on the brain was sure on target in my case. It has held the tumors in the rest of my body since July 05.
