“Four warning signs of lung cancer that appear in the morning”

The US National Institutes of Health confirms that patients with lung cancer, especially those in an advanced stage, often present with symptoms of fever, usually due to infections, and anxiety and depression caused by cancer can lead to fever associated with stress.
heavy sweating

A patient with lung cancer may wake up drenched in sweat, because the fever caused by the cancer causes the body to sweat excessively to cool itself.
dry cough

A dry cough without mucus for more than three weeks may indicate lung cancer. Lung cancer coughs usually start out dry and come in spasms.
blood in sputum

Blood in sputum can also be a warning sign of lung cancer. Phlegm, as it is known, is a thick type of mucus that is made in the lungs.
