Thanks for the update on your uncle. We're very sorry he was positive for cancer.
When things settle down a little bit, please add a signature to your posts containing your uncle's diagnosis. That will help us respond a little better.
You uncle probably has some time to make a decision, so he should get all the info he needs to make a decision comfortable to him. Second and third opinions on a course forward won't discourage his existing doctor, either.
Try to stay positive. This disease may be conquered when caught in various stages.
Please let us know how we can help to support you and your uncle.
All the best,
