10 Symptoms of Non-Small Cell Lung Cancer

Coughing up blood. One of the more alarming symptoms is the presence of blood in sputum. Sometimes it looks like small streaks; in other cases, the sputum may be pink or rust-colored. While coughing up blood can occasionally be caused by infections or a ruptured small blood vessel, persistent or recurring blood in sputum is strongly associated with NSCLC.

If you notice this sign, especially more than once, medical consultation is essential.
