Oh my gosh - I am so sorry for your diagnosis. I wish had I ideas. Are there any clinical trials you could consider?

You can narrow down your search to locations near you, your diagnosis, your gender, and more...

Here is a video on an interesting new treatment. Seems to be that brain cancer was their first focus. Not sure if metastases to the brain is in the works, but it's worth an inquiry.

the ted doc withe the electric field would prob work with a hat electro distributor so if i tell him to make me one i may have a chance kinda feel screwed over that there is a treatment but no chance of getting it

My wife was diagnosed with Stage IV colon cancer with KRAZ mutation almost three years ago April. The mutation is not one that is conducive to a good prognosis. She has beaten the lowest odds but faces an uphill battle. The metastasis is the same as yours: liver and lungs. The current treatment you are on is what she has gone through also. In the last two weeks she had a caniotomy to remove a tumor at the base of her brain near the cerebellum which was causing dizziness, nausea, and change in behavior. They will be doing a direct laser radiation to the surgery site to reduce the re-occurrence rate.

As I have told my wife, keep moving forward. Find a great support system and doctors you feel comfortable with. They will see you through the low lights and give you great confidence at the highlights. Best of luck to you.
