Smoking causes cancer in 10 parts of the body

There are many studies on the association between usecigaretteand cancer have been conducted, these studies estimate that about one-third of all cancer deaths are related to tobacco use.cigarette.

1. Lung cancer

Worldwide, the incidence of lung cancer has increased rapidly over the past 60 years, much more than other major cancers, and this rate appears to be closely related to the increase in the number of smokers.

90% of the 660,000 cases of lung cancer diagnosed worldwide each year are from smoking. Assuming a 1 in 1 lifetime risk of lung cancer for non-smokers, smokers are 10 times more likely to develop lung cancer than non-smokers.

The risk varies depending on the type of cancer. The risk increases with the number of years you smoke, the number of cigarettes you smoke daily, and the age you start smoking.

Non-smokers married to smokers have a 20% higher risk of dying from lung cancer than those married to non-smokers, and the risk of dying from lung cancer increases with the number of cigarettes smoked by the spouse.

Only about 13% of lung cancer patients survive after 5 years. The death rate from lung cancer is 22 times higher in male smokers than in male non-smokers, and about 12 times higher in women.

2. Cancers in parts of the head and neck

Head and neck cancers include cancers of the esophagus, larynx, tongue, salivary glands, lip, mouth, and throat. The risk of these cancers increases with the amount and duration of smoking.

Esophageal cancer: Smokers are eight to 10 times more likely to develop esophageal cancer than nonsmokers. These risks increase by 25 to 50 percent if smokers also drink a lot of alcohol.

Laryngeal cancer: Smoking causes 80% of all laryngeal cancers. Smokers are 12 times more likely to develop laryngeal cancer than nonsmokers.

Oral Cancer: Smoking is the leading cause of cancers of the tongue, salivary glands, mouth, and throat. Men who smoke are 27 times more likely to develop oral cancer than men who do not smoke.

Nasal cancer: In the long term, smokers are twice as likely to develop nasal cancer as non-smokers.

3. Kidney and bladder cancer

Smokers are at increased risk of both kidney and bladder cancer. An estimated 40 to 70 percent of bladder cancer deaths are due to tobacco use.

4. Pancreatic cancer

The pancreas is a vulnerable gland to cancer because cigarette smoke enters the body and reaches the pancreas through the blood and gallbladder. It is estimated that smoking is the cause of 30% of all pancreatic cancers.

5. Genital cancer

Vulvar cancer: Cancer of the vulva, part of the female reproductive system, is usually rare. However, women who smoke are twice as likely to develop vulvar cancer.

Uterine cancer: The link between smoking and uterine cancer has only recently been discovered. At least 12 studies have found that women who smoke have an increased risk of uterine cancer, and the risk increases with the amount and duration of smoking.

Penile cancer: Penile cancer has become more common in men who smoke than in men who do not smoke.

6. Anal and colorectal cancer

Recent evidence has shown that smoking plays a role in causing anal and colorectal cancer. In a large study conducted in the US, for men and women, smokers had a 75 to 100% increased risk of cancer…compared to their non-smokers of the same age./.
