Cancer is a group of diseases that is characterized by uncontrolled cell growth leading to invasion of surrounding tissues that spread to other parts of the body.

Take a deep breath: Life is full of surprises, some good, some no good at all. This might all be a false alarm. Your child will sense your panic.

I had a chest X-ray done. The doctor said everything is normal. Would an X-ray show a blood clot or othrr lung disease?

I had a chest X-ray done. The doctor said everything is normal. Would an X-ray show a blood clot or othrr lung disease?

Perhaps: X-rays show changes in structure by their ability to absorb the rays. This is why bones show up best. Soft tissue changes must be dense or extensive to be seen on an xray. If your chest xray is "normal" than any diseas present is below xray threshold. Your doc, based on your clinical situation could order a ct scan or perhaps an MRI if the results would be helpful. ...Read more

Does lung cancer cause intermittent fleeting rib pain, or would this be advanced disease?? 25, doc says lungs sound clear, 9 -yr pack hstry

Non-specific: Fleeting chest pains are not specific for lung cancer. It could be caused by a host of other benign reasons like muscle pain, rib pain from strain or inflammation. Pneumonia or pleurisy can also cause it. If you are worried about lung cancer and you are a smoker, check with your doctor about a screening CAT scan of the chest. If it is negative, time to stop smoking! ...Read more

Hi doctor, m cured frm TB bt TB left scars..Can i get lung cancer/any other disease bcz of TB scars? 22 year old female. I don't smoke. Plz reply me.

Hi doctor, m cured frm TB bt TB left scars..Can i get lung cancer/any other disease bcz of TB scars? 22 year old female. I don't smoke. Plz reply me.

Don't worry: We've both been cured of TB and that's a good thing. The tiny statistical cancer risk that these old scars pose (and not everybody believe they even do) isn't something we can do anything about. You can't remove the scar, and nowadays it's not considered even worth getting radiation to look for it. Just be grateful that TB is now manageable. Best wishes. ...Read more

Positive methanine challenge indicating reactive airway disease for pft what's that mean? Lump feeling throat for months heavyness taking breaths. Would lung doc bronchoscopy and ent doc normal rule out something throat caused by cancer ? Weak pulse

Positive methanine challenge indicating reactive airway disease for pft what's that mean? Lump feeling throat for months heavyness taking breaths. Would lung doc bronchoscopy and ent doc normal rule out something throat caused by cancer ? Weak pulse

RAD: The challenge test just confirms that your airways react with some tightening/wheezing which reduces your lungs ability to move air. It is often used as a marker for asthma,RAD but beyond that tells you little.If you have had all these tests & they have not spotted a cancer,that should not be considered as a cause. If they eliminate a structural problem for your sensation it must be something else ...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
