Lung cancer is the third most common cancer
after prostate gland and breast cancer. A study has been reported 63,000 deaths
per year in India due to the lung cancer. Although,
there must be numerous of other factors behind the occurrence of lung cancer
but most common of all is smoking and tobacco consumption.
Thankappan and thresia has reported that there
has been 5 million deaths per year i.e., approximately one in ten adults in the
world including 2.41 million deaths in developing countries and 2.43 million
being attributed to developed countries occur only because of tobacco
consumption.
Chewing or smoking tobacco and its products
contains high amount of carcinogenic nicotine and its derivatives. Excessive
inhaling of nicotine results in the alteration of signalling pathways responsible
for proliferation, apoptosis and metastasis. Lung cancer culminates from the
series of changes in the signalling pathways.
