Generally, the cells in our lungs and other parts of the body have a specific growth and death cycle that normally controls the cell count and keep a check on it. Cancer develops when a certain set of changes\/mutations develop in a normal cell.\u00a0 When these sets of mutations affect genes in ways that hinder the natural growth and death cycles of cells, thereby causing unregulated cell division and hence, causing Cancer. Genetic testing for cancer at an early stage helps in reducing the risk of LC. <\/p>\n\n\n\n

There are various kinds of cancer, that exist, out of which Lung Cancer<\/a> is one of the most common ones. Being the second most common cancer in men and the fifth most common cancer in both men and women together, LC originates from the lung tissue, usually from cells lining the air passages. There are two main types of lung cancer: small cell lung cancer (SCLC) and non-small cell lung cancer (NSCLC). These types are classified on how the cells look like. Around 80% of all lung cancers are non-small cell type. Non-small cell type is further sub-divided into 3 major categories: adenocarcinoma, squamous cell carcinoma and large cell carcinoma.<\/p>\n\n\n\n

It can spread to different parts of the body through the blood and lymphatic vessels. This is called metastasis. Nearly 40 % of people who are newly diagnosed with LC already have metastasis to other parts of the body for e.g.\u00a0lymph nodes, liver, bone, brain, adrenal gland, etc.<\/p>\n\n\n\n

Factors affecting Lung Cancer<\/a>!<\/strong><\/p>\n\n\n\n

Tobacco:\u00a0<\/strong>Tobacco in any form is harmful, whether smoked or smokeless. Smoking cigarette and beedi is the major risk factor for lung cancer. It increases an individual\u2019s risk of getting LC by 15 to 30 times. The risk of lung cancer increases with the number of cigarettes smoked each day and with increasing duration of time, the person has been smoking. And eventually, the risk decreases if the individual quits smoking.<\/p>\n\n\n\n

Tobacco not only affects LC but can also cause cancer anywhere in the body like head and neck region, blood, stomach, liver, pancreas, colon, bladder, kidney, cervix and cancer in the bone marrow.<\/p>\n\n\n\n

In India, around 87% of males and 85% of female patients with LC have a\u00a0history of tobacco smoking and also of passive tobacco exposure.<\/p>\n\n\n\n

\u2022 Exposure to chemical carcinogens: <\/strong>People having exposure to arsenic, chromium, diesel exhaust, silica and nickel have a high risk of developing lung cancer.<\/p>\n\n\n\n

\u2022\u00a0Indoor burning of coal:\u00a0<\/strong>Indoor combustion of coal, either for cooking or heating, increases the risk of LC.\u00a0 It results in high levels of indoor air pollution due to a wide range of pollutants that damage health.<\/p>\n\n\n\n

\u2022\u00a0Lung Infection:\u00a0<\/strong>Having infections like pneumonia or disease like tuberculosis that can lead to scar tissue<\/a> formation in the lungs may have an increased risk for adenocarcinoma of the lung, a type of LC. <\/p>\n\n\n\n

\u2022\u00a0Lifestyle & Diet:<\/a>\u00a0<\/strong>There are some factors that may prevent LC and some which may increase the chances of the same. People with a low intake of foods rich in beta-carotene, such as carrots, have a higher risk for lung cancer. Deficiency of Vitamin A increases the chance of developing squamous cell carcinoma of the lung in smokers. <\/p>\n\n\n\n

\u2022\u00a0History of Lung Cancer:\u00a0<\/strong>People with a family or a personal history of LC especially in first degree relatives have a higher probability of lc. The risk may be higher if there is a positive family history since they share the same living space. There is a risk of developing LC in the other lung if you have had lung cancer on the other side. <\/p>\n\n\n\n

There’s no sure way to prevent lung cancer, but you can always reduce your risk in some ways:<\/p>\n\n\n\n
