How can nodal enlargement in lung be treated?

Hello doctor,

I need advice after my second computed tomography (CT) chest result. Six months back, I went for a CT scan because I have got chest pain which suddenly comes and goes and I wanted to go for a check-up. The CT showed a right-sided nodule measuring 3 mm and was advised to radiopharmaceutical therapy (RPT) interval scan in six months. I have done the second CT, the previous nodule is still there and they found another one. In the left lower lobe (LLL), a 4 mm nodule is representative of an intrapulmonary lymph node. No suspicious lung lesion. Tiny 3 mm right lower lobe (RLL) nodule noted. No enlarged lymph nodes. Mild thymic hyperplasia. The partly visualized upper abdominal viscera appear unremarkable. No aggressive bony lesion. They said I do not need to do anything which is strange because there are two nodes now and the second one was not there six months ago. Do I need some kind of medicine therapy to clear my lung from this node or do I need to check if it is growing or not after one year?
