Cancer - An Overview

Cancer Smoking

Owing to the large number of chemicals present in cigarette smoke, smoking can lead to cancer in various parts of the body.

Amongst the most commonly discussed forms of cancer that occurs due to smoking is lung cancer. There is a considerable ‘dose response’ relationship when it comes to smoking and lung cancer, wherein the more you smoke, the more are the probabilities of your getting lung cancer. 90% of lung cancer deaths in men and 80% of lung cancer deaths in women are attributed to smoking.

Oral cancer (mouth cancer) also sees smoking as a primary factor (along with other forms of tobacco intake). If you have oral cancer, there is a possibility that it will spread further down the oral cavity to the larynx and the oesophagus, and continuing smoking would only hasten the process.

Bladder cancer also sees a considerable effect of smoking, wherein about half of all the bladder cancer related death in men, and around 30% in women, are attributed to smoking. This is because some of the carcinogens that enter your body in the form of cigarette smoke enter your blood. They are then filtered by your kidney, and get concentrated in the urine. Once in the urine, these chemicals work their way in damaging the inside lining of your bladder. This increases the probability of your getting bladder cancer.

A new study has also shown that smoking increases the chances of your getting cancer of the pancreas (pancreatic cancer). The study also went on to show that people who smoked lesser for a long period were more vulnerable to getting pancreatic cancer than people who smoked more but for a shorter duration.

Kidney cancer is another form of cancer that you risk each time you light up, as a smoking history is one of the reasons for kidney cancer. Renal cell carcinoma, the most common form of cancer that affects the kidney, affects smokers way more than non-smokers (almost two times more). While your kidneys handle the waste filtration of your body (as urine), chemicals such as tar and nicotine can damage the kidney and impede this process. Besides, the carcinogens can also damage your kidney tissue.

The possibility of your getting stomach cancer go up around two times if you are a smoker, and smoking also increases the risk of your getting cervical cancer by around 60%. Recent data has shown that close to half of Australia’s indigenous women smoke, putting a large section of the population at risk of contracting this otherwise preventable form of cancer.
