Re: Lung Cancer fears
Feeling short of breath is quite common but very infrequently is actually associated with dyspnea or respiratory distress. More commonly, this sensation is caused by either upward pressure on the diaphragm from excess gas or air trapped in the upper abdomen or alternatively a stress or anxiety factor. It is a common feature among persons who are anxious or under significant stress, wherein patients feel as though they are unable to experience the usual deep inspiratory breath that so often has a calming effect. Thus, there is often the attempt to achieve this breath through a forced and voluntary effort, which serves to produce repeated attempts as concern grows.
Shallow breathing is also very common among persons that may be experiencing anxiousness or worry and produces slight changes in blood-gas balances that can sometimes exacerbate the sensation and even make persons feel light-headed. Tightness in the chest also results from anxiety and produces sensations that one cannot get enough air. It is, however, merely a sensation and not actual air starvation.
Space-occupying masses within the lungs generally are asymptomatic and most often discovered during routine exams or evaluation of an unrelated symptom. Long before dyspnea would be an issue, you would experience a broad variety of other symptoms for which you have made no mention. I would tell you here that in my 40 years of having practiced medicine that your fears are entirely unfounded and I believe some irrational thoughts are causing your fears to be on a runaway train.
You'll be fine. Take a breath and relax.
