Lung Cancer Symptoms - Major Signs Of Lung Cancer

Lung cancer symptoms wouldn't show until advanced stages of the illness. One fourth of patients discover the malignant tumor, as a solitary small mass called coin lesion, by accident while x-raying the chest for other reasons.

Lung cancer is the most deadly of all kinds. Specialists state that one out of every fourteen Americans, women and men, would diagnose the disease in a lifetime and more than 150000 victims are killed by this terrifying illness every year.

The major causes of this cancer are tobacco, active and passive smoking, exposure to asbestos, Radon gas and familial genetic predisposition.

Patients develop lung cancer symptoms as the illness advances, due to physiological disruptions caused by the initial tumor and the metastatic tumors in other parts of the body: a malignant tumor would grow in the lung and spread to the surrounding structure using the bloodstream or the lymphatic system to expand. Inversely, metastatic cancers from other primary tumors of the body are often found scattered throughout the lung, most often in the peripheral rather than the center.

In addition, to the liquid volume that the pleura produces to cushion the lung, a malignant tumor would squeeze the lung in the rib cage, therefore breathing becomes difficult, wheezing and painful.

Coughing up blood is one of the spectacular and alarming lung cancer symptoms, is caused by tumor dying cells. Blood spitting is not specific to lung cancer symptoms only, but can also be attributed to other lung problems such as pneumonia.

Besides, victims would excessively lose weight in no time.

A physical examination would denote, in the case of lung mesothelioma, unusual masses of tissue under the skin in the chest and abdomen.

One shouldn't wait until spitting blood but should consult a doctor as soon as he or she develops signs indicated as lung cancer symptoms.
