10 Early Signs of Lung Cancer
Early Sign #2: Shortness of Breath
When our breathing muscles cause our lungs to expand, it causes fresh air to be sucked in. Oxygen in this air is then absorbed into the body through the lung’s walls, where it is then taken to where it is needed by our red blood cells. As the blood is pumped around the body, it eventually returns to the lungs where it picks up more oxygen again.
In cases of lung cancer, the lungs are going to be less efficient as they usually would be. This causes less oxygen to be absorbed, and this causes us to become short of breath. If you do often find that you are short of breath for no apparent reason, you should arrange to get it checked out.
