### input:
My father has been a smoker for 50 years. He saw a doctor regularly. Anyway, two weeks ago, he met with a new primary doctor who ran some tests. They found he had an 8cm aortic aneurysm. He had a procedure last week (like a few days after the initial finding ) and had that repaired/stented I believe. Another test he had done with this new primary showed two spots on his one lung (one spot was on a lymph node?). It was pretty large. He has to wait to be released from the vascular surgeon to have a biopsy on his lung. He is scared to death obviously (and quit smoking this week). Anyway, the other day he went to have his bandage changed and a doctor ran blood tests..and also gave him an antibiotic saying that his incision was pretty swollen still (hemotoma)....and I guess he gave him the antibiotic to help with that?? Anyway, the blood work came back and his white blood count is high. What does all of this mean? 2 spots on lung and now high white blood count. Could the spots just be...incidental and the high WBC be due to an infection (or does the WBC mean worse cancer? There were only two spots on one lung...so could it have traveled to other parts the body already if is indeed lung cancer?

### output:

Thanks for your question on Chat Doctor. In my opinion high WBC count is due to infected hematoma. It is known as SSI (Surgical Site Infection). It is a kind of complication of surgery. So antibiotics are prescribed by doctor to control the infection. And about the lung spots, I advise you to get done CT THORAX with contrast. As CT gives excellent view of lung parenchymal. And appearance on CT will guide us whether biopsy is needed or not. Chances of malignancy is there since your father is smoker and old age. So better to get done CT thorax and SOS biopsy.
