Hi
My dad had a severe heart attack and quadruple bipass surgery 11 months before his Stage 3B NSCLC was diagnosed. The mass was visible - 2-3cm on the xrays done at the time of his bipass but his doctors missed it. By the time we diagnosed the cancer it had grown to 6 by 8cm. Its been a week into his treatment of daily radiation and chemo of taxol and carboplatin. He also has high blood pressure and diabetes. He's still on his asprin - blood thinner so maybe your dad too can go on this particular drug combo for his chemo. I recall my dad's oncologist saying carbo is given to patients who's hearts are less than healthy.
I hope your dad gets well soon - good luck
