Another story from preceptorship. A patient came to clinic last year convinced he had lung cancer. He was a previous smoker (1 pack/day for 10 years), but had no symptoms, no family history, no other risk factors, in his 40s, nada, zip, zilch. So the doc ordered a blood panel, guy was healthy as a horse, and sent him on his way. He couldn't even elucidate why the patient was suddenly convinced he had cancer.
Got a call from radiology at the local community hospital this week. The guy had presented to the ED with acute chest pain. Chest xray revealed multiple metastases in his lungs.
As the french say: déveine.
