Smoking and cancer
Smoking accounts for 30 percent of all cancer deaths and 87 percent of lung cancer deaths. The risk of developing cancer is 23 time times more in male smokers compared to non-smokers. Smoking or the repetitive use of cigarettes is associated with the risk of 15 types of cancers. Fewer than 10 percent of smokers are likely to be affected by lung cancer and the others are more likely to be detected with other forms of cancer like mouth cancer and throat cancer.
A study by researchers from American Cancer society has shown that 48.5 percent of the deaths caused only due to cigarette smoking is related to twelve different types of cancer. Some of the Cancers caused by smoking are
2. Colon and rectum
4. Oral cavity
13. Acute myeloid leukemia
Records have shown that in 2011 around 346,000 adults around the age group of 35 years died due to cancer caused only and only due to smoking. Among them, only 168,000 deaths were caused due to lung cancer. Lung cancer has the highest number of deaths with a count of 80.2 percent followed by larynx cancer with a close count of 76.6 percent. About half of the cancers or more cancers are related to smoking. 23.6 percent of the people who smoke are accounted for having liver cancer whereas 9.7 percent accounted for colon and rectum cancer. In 2015 an estimated 171,000 people died of cancer caused due to smoking.
Around 80 percent of the 1.1 Billion smokers or passive smokers live in live in low and middle income countries where the burden of tobacco is the highest and that high effect or use of tobacco takes a high toll on the lives of the people staying there which in turn puts a heavy burden on the financial stability of the people which increases their loans and borrowings.
In some countries, children from poor households are frequently employed in the farming of tobacco to stabilize family income. These children are especially vulnerable to green tobacco sickness caused by the nicotine that is absorbed through the skin from the handling and management of wet tobacco leaves.
More than 100 studies from high-income countries have shown that an increase in taxes on cigarettes and other tobacco products lead to a significant reduction in the overall usage of tobacco. The increase in prices and taxes of tobacco products shows the combination of increased smoking cessation, reduced relapse, lesser smoking initiation and decreased consumption among continuing tobacco users.
