You missed a few steps again.

1. First, you have to understand that current approved biomarkers are archaic and incompetant. (A flip of the coin) Heads you have cancer maybe...tails you don't have cancer maybe...

2. The use of a true high efficient biomarker (such as Recaf) with a 95% +/- rating will provide one with a true accurate assesment of cancer yes or no.

3. You then get a pet scan or such

4. If positive, You then get a biopsy.

5. Then if biopsy comes back positive you take necessary steps to correct the cancer. If it is negative well then you deal with it.

6. The most, most, most, most important part of this entire discussion from day 1 till now is EARLY DETECTION with a test that is up to date with high sensitivity and specificity unlike the current markers which have niether.

You first get a general screening with a true Biomarker such as Recaf then you can make some intelligent decisions.

I don't know what hospital you are refering to that would take out a perfectly good lung without doing a biopsy first. In fact I would venture to say that was fabricated. You forgot the steps in between.
