10Wheezing
Wheezing is the high-pitched whistling sound that often occurs when you breathe out or in. When lung cancer develops, the tumor would constrict or block your airways and trigger this symptom. The sounds can be audible or inaudible, depending on your stage. If the condition progresses, you might notice the wheezing noises more easily in each breath. Keep in mind that wheezing is also common in many other conditions, such as allergies or asthma. Thus, have it confirmed by your healthcare provider for early treatments. [10]
