Shortness of Breath
Lung cancer can also trigger dyspnea or shortness of breath, particularly in those people who never smokers. These changes in your breathing patterns would happen when the tumor narrows or blocks your airways or when fluids from cancerous cells accumulate in your chest. Regardless of the cause, you should never overlook this sign. In most cases, you might notice the condition during physical activities. If you feel tired and dizzy due to a lack of oxygen, make sure to visit your healthcare provider immediately. [2]
