Some of the risk factors for bleeding following bronchoscopy is having a malignancy or an immunocompromised state. The etiology of this remains uncertain. The investigators suspect that individuals with malignancy have abnormalities involving certain factors that influence the coagulation pathway.
The investigators plan to measure these factors prior to and after bronchoscopy.
This is a prospective observational study looking at some coagulation factors in individuals with lung cancer. We are looking at BAL and plasma. We would like to see if there is a difference in the levels and if this is the reason behind the higher incidence of hemoptysis in patients with lung cancer.
37 studies on the registry are indexed under Hemoptysis; 6 are open to participants now.
This study's enrollment of 10 is below the median of 176 across 15 observational studies indexed under Hemoptysis.

Exclusion Criteria:
Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.
Blood tests of how long blood takes to clot. The INR is the prothrombin time (PT) put on a common scale; about 1 is usual for someone not taking a blood thinner.
Criteria often make an exception for people on a blood thinner such as warfarin, whose INR is raised on purpose.
Blood cells that help blood clot. Too few raises the risk of bleeding and bruising. A usual adult range is about 150–400 × 10⁹/L (150,000–400,000 per µL); each lab has its own reference range.
