here is current CT slice - on your left is my right side filled with large masses of tumor.  Air is black on CT so that large mass of tumor should be my right lung which has disappeared.  some tumor coming back through the chest wall on that side.
on your right is my left lung looking black - so that is good, although it is compressed from all the tumor from the other side pressing across.
none of this has changed much in 4 weeks (although a little worse)
what has changed is the little bit of tunor behind the main breathing tube in the center (kinda a half moon shaped black airway, with tumor underneath it). This has grown a lot in 4 weeks, and is partially blocking the left lung airway - might be responsible for some of my symptoms, but we do not want it to get worse - this is a rapid grower - so zapping that with targetted xrays to prevent future preoblems and help alleviate current ones hopefully.
