Lung Cancer – the major symptoms , causes & types

Lung Cancer is the result of abnormal division of cells in the lungs forming a lump called tumor which is malignant in nature. As per studies it is the most destructive form of cancer causing due to cigarette smoking.

Lung Cancer is much more harmful & leading reason behind cancer death than any other type of cancer like breast, ovarian, colon & prostrate cancers. Mostly it remains undiagnosed at an early stage & gets diagnosed only when it is on the advanced stage.

Causes of Lung Cancer:

The primary cause of lung cancer is cigarette smoking. According to research it has been found that cigarette smoke contains 4000 chemicals, most of which have been identified as cancer causing agents (carcinogens )  which affects the lung cells directly. The risk of getting lung cancer from cigar & pipe smoking is less in comparison to cigarette smoking.

As per studies, a person who smokes 1 packet of cigarette per day has minimum 20-25% times more chance of developing this cancer than a person who has never smoked in his entire life. Lung  can develop among people who have never smoked at all but the ratio is comparatively too less than among those who are regular smokers.

Tobacco smoking is the main reason behind this kind of cancer, although heredity (i.e. family history) sometimes plays a vital role in developing this disease also. If in your family there is already someone who has /had suffered from this fatal disease then there is a chance of yours also going through the same.

Other causes might be due to passive smoking, air pollution, workplace chemicals, & inhalation of asbestos (a kind of material apply for insulation & fire proofing).

According to studies it has been known that approximately 3000 deaths from lung cancer in U.S. are from passive smoking only.

Types of Lung Cancer:

2 main types of lung cancer are there:

Small Cell Lung Cancer (SCLC): This type of cancer is only common among the heavy smokers & those are only visible with a microscope. SCLC is the aggressive one in comparison to NSCLC. It metastasizes very quickly & spreads all over the body.

Non Small Cell Lung Cancer (NSCLC) : Most of the lung cancer are grouped under NSCLC. This type of cancer includes squamous cell carcinoma, adenocarcinoma & large cell carcinoma.


 Symptoms of Lung Cancer:

Cancer in lungs is hard to diagnose its early stage since in most cases this type of cancer do not display any symptoms until it is on the advanced stage. Though normally the symptoms include:

–          Coughing up blood

–          Cough which is continuous for many days & does not go away & gets worse day by day

–          Unexpected  amount of weight loss without any reason

–          Frequent occurrence of infections like bronchitis or pneumonia or tuberculosis.

–          Having breathing problem

–          Hoarseness

–          Feeling tremendously weak & tired

–          Chest pain

–          Stridor ( a harsh vibrating noise while breathing in )

When to consult a Doctor?

If anyone is going through any one of the above symptoms on a regular basis then it is always advisable to consult with a Doctor. If you want to quit smoking & unable to do so, then please do consult with a Doctor. He can guide you in a proper way & can recommend you certain procedures like counselling, medication & nicotine replacement products.

Prevention:  The one & only prevention is to quit smoking. Though you have continuously smoking for many years, quitting smoking do reduces the risk of this disease. Also try to avoid passive smoking. Try not to stay with people at the time of their smoking or ask them to smoke outside.
