The abnormal and uncontrolled growth of cells in the lung tissues can cause lung cancer which is also known as bronchogenic carcinomas. The abnormal cell division may begin primarily in the air passage of the lungs. In the advanced stage, it may affect the other part of the lungs and body organs as well. Also, Lung Cancer generally has a survival rate of 16% at 5 years.
Individuals aged 65 years and above are more prone to develop lung cancer than the younger population. Lung cancer generally strikes the elderly population. There were only a few cases in the year 1930s but thereafter the world witnessed a steady rise in the number of cases of lung cancer as the practice of cigarette smoking increased.
Both globally and nationwide, lung cancer continues to threaten the lives of both men and women. It is considered to be the leading cause of death amongst both men and women across the globe. According to WHO, in India, Delhi’s air quality has already been rated as one of the most hazardous in the world. This is due to increasing industries, automobiles and burning of crop stubble releasing a lot of gasses and dust particles. Indian statistics on lung cancer reveals that as many as 90,000 men and 79,000 women are affected each year.
Types of lung cancer
Lung cancers are of 2 types:
Smokers are a greater risk of lung cancer than non-smokers. Smoking alone accounts for about 80 – 90% of lung cancers. Whereas the rest 10 – 15% cases of lung cancer occur due to genetic factors, air pollution and exposure to radon gas and asbestos. If you start smoking at an early age and then with time you also increase the number of cigarettes you smoke in a day, you are actually increasing your chances of being affected with lung cancer. This can be well understood with an example: an individual who smoked 2 packs of cigarettes for a period of 10 years is known to have a 20 pack-year smoking history.
However, there are some eye-opening facts that narrate a different story. Recent studies have shown that lung cancer is no longer just “smoker’s disease”. The number of smokers has decreased in the past decade, but lung cancer occurring to non-smokers has remained steady, which means that there are some other factors to blame too. These factors have been identified as exposure to asbestos and air pollution. About 8% of lung cancer is caused by inherited factors.
A certain percentage of individuals would usually not experience any symptoms of lung cancer. In cases, when they do the symptoms would include:
Who Should Be Screened?
Persons having a history of heavy smoking
Persons who were smokers but quit smoking
Persons exposed to heavy pollution.
Persons who had lung cancer in relatives.
An x-ray of the chest should be enough for preliminary diagnosis of tumor in the lungs. Once the x-ray is done, the following diagnostic procedures are conducted for confirming lung cancer.
Treatment of lung cancer will depend on - the stage and type of cancer, location of the tumour within the lungs and overall general health of the individual. The following treatment options are considered.
The doctors may combine one or two methods for better efficacy and to lessen the effect of the malignant neoplasms. With the new advancements in medical science, it has really been possible to have significant control in the treatment of lung cancers by proper consultation.
A recent report published in The Telegraph states that a new study has been designed that aims at studying the ways the tumour genes mutate. This would enable doctors to develop medications that would inhibit gene mutation from taking place.
