In summer 2006, I was diagnosed with infiltrating grade 1 ductal carcinoma tubular breast cancer with 2 masses forming. Cancer not in sential node. I had a double mastectomy with reconstruction. I did not take chemo since stage 1. From a chest and abdomen CT this summer they found spots in my liver and we are watching (no spots in lungs). This February, 2007, I had a CT of abdomen to look at the spots again and they found a suspicious spot, so I had my first PET scan. Spots in my liver not hot. They find a hot lymph node in the center of my chest. Then I had a CT of chest to look at hot spot. Hot shop did not show lump, so they think it is a lymph node. However, they did find a very small lump in the lung. This did not show on PET. They think this could be an infection; however they tested me for TB, several funguses, and bacterial (one being the bird and soil infection?) infections all negative. I had a bronscopy but the lump was too far away to reach. They also did just a chest xray. I am a non-smoker. I do have shortness of breath and had a sinus cold all winter. I have a great grandmother, grandmother, and great uncle all with primary lung cancer. Question: What other tests should I ask for? Why might the lymph node be hot what could it be? From my breast cancer? Should I just ask to have it removed? How do they test for the lymph node with cancer when it
