I was mid diagnosed for months. I had symptoms similar to your. Then one day I woke up and one of my pupils was smaller than the other. It was then that I was finally diagnosed with a Pancoast Tumor with Horners Syndrome. The tumor did not show up in any X-rays. Do not listen to your doctors. Insist on a cat scan of the lungs and brachial plexus. If caught early enough. The surgery is not as bad. This is a very serious condition and misdiagnosed too often. Please let me know how you are doing now.
HI,
How are you? What initial diagnostic tests were done? I understand your concern regarding your symptoms. Genes, smoking and environmental factors increases the risk of lung cancer. Imaging techniques include chest X-rays, bronchoscopy , CT scans, MRI scans, and PET scans may help determine the underlying cause. However, definite diagnosis of lung cancer is with a biopsy. Blood in the phlegm may also be caused by an infection. Hope this helps. Take care and do keep us posted.
