Lung cancer: symptoms include hemoptysis

The health body adds: “You may be required to have a blood test to rule out some of the possible causes of your symptoms, such as a chest infection.”

Am I at risk?

Most cases of lung cancer are caused by smoking, although people who have never smoked can also develop the condition.

In fact, “up to a quarter of lung cancers are diagnosed in people who have never smoked,” states the BMJ article.

Occupational exposure and contamination is a lesser known but potentially significant risk factor.
