Smoking causes cancer in 10 parts of the body.

There are many studies on the relationship between usage.cigaretteAnd cancer studies have been conducted, estimating that about one-third of all cancer deaths are related to drug use.cigarette.

1. Lung cancer

Globally, the incidence of lung cancer has increased quite rapidly over the past 60 years, much more than other major types of cancer, and this rate shows a strong correlation with the increase in the number of smokers.

Ninety percent of the 660,000 lung cancer cases diagnosed annually worldwide are among smokers. Assuming a risk of lung cancer of 1 percent for non-smokers, the risk of lung cancer for smokers is ten times higher than for non-smokers.

The degree of increased risk varies depending on the type of cancer cell. The risk increases with the number of years of smoking, the number of cigarettes consumed daily, and the earlier the age at which smoking begins, the greater the risk.

Non-smokers who marry smokers have a 20% higher risk of dying from lung cancer compared to those who marry non-smokers, and this risk also increases with the number of cigarettes smoked by either spouse.

Only about 13% of lung cancer patients survive after 5 years. The death rate from lung cancer is 22 times higher in men who smoke than in men who do not smoke, and about 12 times higher in women.

2. Types of cancer in the head and neck

Cancers of the head and neck include cancers of the esophagus, larynx, tongue, salivary glands, lips, mouth, and throat. The risk of these cancers increases with the number and duration of smoking.

Esophageal cancer: Smokers have an 8 to 10 times higher risk of developing esophageal cancer than non-smokers. These risks are further increased by 25 to 50 percent if smokers also consume a lot of alcohol.

Laryngeal cancer: Smoking causes 80% of all laryngeal cancers. Smokers have a 12 times higher risk of developing laryngeal cancer than non-smokers.

Oral cancer: Smoking is the leading cause of cancers of the tongue, salivary glands, mouth, and palate. Male smokers are 27 times more likely to develop oral cancers than non-smokers.

Nasal cancer: In the long term, smokers have twice the risk of developing nasal cancer compared to non-smokers.

3. Kidney and bladder cancer

Smokers are at increased risk of both kidney and bladder cancer. Of all bladder cancer deaths, an estimated 40 to 70 percent are attributed to tobacco use.

4. Pancreatic cancer

The pancreas is susceptible to cancer because cigarette smoke enters the body and reaches the pancreas via the bloodstream and gallbladder. It is estimated that tobacco is the cause of 30% of all pancreatic cancers.

5. Genital cancer

Vulvar cancer: Vulvar cancer, a part of the female genitalia, is relatively rare. However, women who smoke have twice the risk of developing 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 this risk increases with the number and duration of smoking.

Penile cancer: Penile cancer has become increasingly common in men who smoke compared to men who do not smoke.

6. Anal and colorectal cancer

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