Hi Ruth:
Your situation is common but being that it's your situation, it's VERY critical to you. I always advise a 2nd opinion because all docs are not equal. My choice is CTCA (Cancer Treatment Centers of America) because they have the most advanced technoogy on any cancer. They treat you as a real person - wih no strings attached. Cancer patients have a great reluctance to travel for some reason and most elect to stay with the doc they started with. This is all too often not a good decision. My wife (and I) traveled and got the best care available - far from home but with miraculous results.
It is true that while the lung nodules are tiny (less than 3 mm), they are not life threatening - but treat them now while they are vulnerable, small, and non-aggressive. Xeloda is a good choice for this (an oral chemo that you take at home). It will also attack any other 'live' cancer cells in your body.
Moving to standard chemo, absolutely get a port installed. It is effcient, unnoticed, and can stay in for years without side effects. It saves your veins and unnecessary needle pricks. At CTCA, the port installation procedure is 45 minutes and can be scheduled within hours of your arrival.
The docs there are caring, available, friendly, and extremely experienced at treating all types of cancer at all stages. At no cost to you, it is an option you must consider. 800-FOR-HELP
