It depends on what the "spot" is. It doesn't have to be cancerous to cause a problem, and it sounds like he's having a problem.
His doctors will be watching him closely to make sure that he does not develop heart failure, which is very visible on a chest x-ray. Heart failure on an x-ray will show up as very wet lungs, full of fluid, with an enlarged heart.
If he IS afraid that he is going into heart failure, as in, the veins aren't slightly enlarged and his venous return isn't just SLIGHTLY impeded, they should seriously look at removing the mass. The problem with removing a mass in that area is it requires major surgery and an intensive care stay, with a chest tube put in post-operatively. He might also be put on a life-support machine for a few days. It's a very very very invasive surgery, and it'll be their last resort. Recovery time from that kind of surgery would be at least a month, if not more, as they might have to saw through ribs. Basically, they won't just take it out if they don't absolutely have to. And I have a feeling that's what they're waiting for -- that crucial point where if it gets any worse they're going to have a bigger problem on their hands.
In the meantime, it's a good thing he's getting regular biopsies, because it is possible that it might turn into something cancerous.
P.S.; Is he having regular diagnostic tests to see the degree of blockage it's having, or the rate of its growth? Things like angiograms or at least chest x-rays?
