If one had lung cancer symptoms. Would it show on an X-ray and bloods. ?

It might--or not: Advanced lung cancer would show on x-ray. Earlier cancers are better seen with ct scans. If you have been a heavy smoker for 15 or more years, your risk is certainly much higher of a cancer than a non-smoker. Non-smoking related cancers occur, but usually in much older individuals. ...Read more

In general ,when lung cancer symptoms should appear?
Are they need years or months?

Unclear question: Lung cancer takes years to develop from the time of initial insult. The insult may be smoking, asbestos exposure or radiation. For good health - Have a diet rich in fresh vegetables, fruits, whole grains, milk and milk products, nuts, beans, legumes, lentils and small amounts of lean meats. Avoid saturated fats. Drink enough water daily, so that your urine is mostly colorless. Exercise at least 150 minutes/week and increase the intensity of exercise gradually. Do not use tobacco, alcohol, weed or street drugs in any form. Practice safe sex, if you have sex. ...Read more

Does early stage small cell lung cancer cause muscle loss and malabsorption or are these later symptoms?

Does early stage small cell lung cancer cause muscle loss and malabsorption or are these later symptoms?

Lung cancer cachexia: Muscle wasting and weight loss ("cancer cachexia") are usually late stage occurrences; malabsorption is usually not the cause of these signs, but rather "hormones" released from the tumor cause a hyper metabolic state and also contribute to poor appetite. If you are already experiencing these problems, however, it is possible that the tumor - although localized (stage 1) is unusually active. ...Read more

Fatigue & muscle loss over last year. Some thick phlegm. Just had negative CT. Could this be early small cell lung cancer not yet showing on scan.

Fatigue & muscle loss over last year.  Some thick phlegm.  Just had negative CT. Could this be early small cell lung cancer not yet showing on scan.

Small cell or oat ce: T cell tumor of the lung are usually diagnosed by the pathologist at autopsy. They are not usually the lung cancers picked up when you are alive. Those are adenocarcinomas, or carcinoid tumors of the lung. Helical CT scans are the most sensitive tests for picking these up. Best prevention is never to smoke tobacco or stop today. ...Read more

In past 3years I have had 3 CT scans and 1 pet/ct scan all negative. Do I need more scans to rule out lung cancer? Still have fatigue and muscle loss

In past 3years I have had 3 CT scans and 1 pet/ct scan all negative. Do I need more scans to rule out lung cancer? Still have fatigue and muscle loss

You don't have it: Whether scans cut a risk of one's actually dying of lung cancer is a question I will leave to policy-makers. But your fatigue and muscle loss are not due to lung cancer. I'm glad you're health conscious; I assume you've stopped smoking; and my hope for you is that you'll search for some other explanation AND continue an athletic, fitness-focused lifestyle to richly enjoy these years of your life. ...Read more

Fatigue for 2 years with some muscle loss. Pet/ct scan was negative. What is chance of it missing lung cancer (exsmoker sorry, clean 2 years). Thanks?

Fatigue for 2 years with some muscle loss. Pet/ct scan was negative. What is chance of it missing lung cancer (exsmoker sorry, clean 2 years). Thanks?

Not zero: But very small. No test is perfect. There are a number of reasons for missed diagnosis of lung cancer. However, a PET CT is the best way to identify lung cancers. Not all nodules seen on CT are positive on PET but this is rare. If no nodules are seen on PET or CT, then the likelihood is less than 2-3/10,000. If you are worried, you can have a follow up low dose screening CT. PET is not needed. ...Read more

Lung (Definition)

Deoxygenated blood enters the lungs from the right side of the heart and travels to the lungs. When you inspire, oxygen flows into the lungs, transverses the capilliares and attaches to hemoglobin down a gradient. At the same time, co2 diffuses into the capilaries and is expelled with exhalation. Oxygen rich blood then flows to the left side of the heart and into the ...Read more

Muscle Weakness (Definition)

Muscle weakness is either a subjective or objective symptom based on history or formalized testing. As a result, any complaint of weakness needs to be correlated with testing that can bring out that weakness, which sometimes involves putting that muscle in an isolated and 'disadvantaged' scenario to assess adequately. Such weakness can have multiple etiologies from ...Read more
