Needs evaluation: The answer to your question requires an evaluation and review of the information from the tests you have already had. Cancer and heart disease are both very rare and unlikely in previously healthy 31 year old men.

Methacholine challenge test is performed if your symptoms and screening spirometry do not clearly or convincingly establish a diagnosis of asthma. Methacholine is an agent that, when inhaled, causes the airways to spasm (contract involuntarily) and narrow if asthma is present. If positive,, you have asthma, and there are medications for that. See your doctor to start a maintenance Rx.

Asthma : Studies show that a positive methacholine test may indicate you have asthma however the test needs to be interpreted carefully. Did you have an obstructive pattern on spirometry reversed by bronchodilator? Trial of rescue inhaler indicated and talk with a pulmonologist. Sorry you are not feeling well but don't worry your doctors will get to the bottom of this. Don't worry and good luck.
