As far as I know, they can do a ''quick'' biopsy, but the final word is given by the ''slow'' one so we went that way.
They did perform 3 CAT Scans abdomen, chest and pelvis and the chest one showed three small nodules in the lungs, between 7 and 2 mm. The doctor said to wait for the nut biopsy and then wait three months to see if the lung thing have changed.
It seems that usually testicle tumors spread to the linfatic nodules and/or stomach (I've really abstained from resarching too much on the net for now)...anyway, we'll see.
I'm confident about all this crap...I'm in the hands of God, my doctor and my family and friends.
All the best.
