Common signs and symptoms of lung cancer

Many women worry about getting breast or ovarian malignancy. But did you know that lung cancer kills much more American people than other cancers do?

Cancer develops when body cells undergo certain transformations and begin to grow and propagate without any control.

Malignant tumors take nutritive elements, space and oxygen from normal cells, destroy them and affect normal functioning of the organs.

Lung tumors are commonly malignant and can spread to any other body region. It’s also a big problem that lungs contain wide net of vessels and lymphatic tubes, which can act as pathways for cancerous cells.

There are two general kinds of lung cancer. Small cell lung malignancy is a less common type, which usually appears in heavy smokers.

Most lung cancers are non-small cell lung neoplasms that involve adenocarcinoma, squamous cell carcinoma and large cell carcinoma.

Smoking is a well known and the most significant risk factor for lung cancer. Cigarette smoke contains more than 4000 harmful substances, which can damage lung cells and trigger their transformation.

The more cigarettes you smoke, the higher chances of this disorder you have. Number of years you’re exposed to tobacco smoke plays a role too. Even secondhand smoking was found to boost risks of experiencing lung cancer.

Having family history of this dangerous condition and being exposed to arsenic, asbestos or other carcinogens can also increase your chances of getting lung neoplasm.
