Is any of this happening?
Be seen today
Seek urgent medical assessment if you cough up more than a few streaks of blood, have increasing shortness of breath, or develop fever and worsening breathing during a chest infection.
These signs can have causes other than a carcinoid tumor, but they need prompt assessment.

Does any of this apply?
Book an appointment
Arrange a routine medical appointment if you develop a cough or wheeze that persists, repeated infections in the same area of the lung, unexplained flushing or diarrhea, or occasional blood-streaked mucus.
If you have already been treated, report new symptoms and attend planned scans even when you feel well.
Every sign above is quoted from the sofidex article on Lung carcinoid tumors. If you are not sure, err upward — it is always reasonable to be checked.
