I had breast surgery about 13 yrs ago. I'm in great health and feel wonderful. I eat right, drink only reverse osmosis water, stay away from food additives (aspartame,splenda etc.) as much as possible. I started spitting up blood about 3 years ago. It lasted a few months then went away. In Feb.2006 it came back. Sometimes I feel a pulling in my chest if I get in certain positions. I've been careful not to extend that area becuase I have spit up blood when I do. I have no pain. Can the scar tissue from the breast cancer cause this problem? If so what can you do for it? I'm a Veteran and am in the process of getting a CT ordered. The chest x-rays and the test with the scope down my throat, was clear. Thank you.
