Tobacco Use and Lung Cancer

Lung cancer is the major cancer slaughter among men and women. There are two types of lung cancer, non-small cell lung cancer and small cell lung cancer. There are various factors that can cause lung cancer, but the main cause of lung cancer is smoking. What is lung cancer? This is a question many people are still asking questions. Lung cancer is definitely something you want to educate so you can identify it. Healthy cells grow and divide into the body to keep functioning, but even if the cells do not require cells to continue growing, this growth can become unmanageable.

The most important cancer caused by tobacco use is lung cancer. In all cases of lung cancer, smoking is related to about 80% to 90% of cases, which is the leading cause of male and female cancer deaths, causing about 80% of deaths from this disease It is. Smoking is also associated with oral cancer, throat cancer, esophageal cancer, stomach cancer, pancreatic cancer, cervical cancer, kidney cancer, bladder cancer, acute bone marrow cell cancer 1. It is not the only form of tobacco use related to cancer.

Tobacco smoke accounts for one-third of cancer deaths. The first signs of the risk of tobacco smoke are coming from the emergence of lung cancer as the main disease. Lung cancer was one of the most rare types of cancer before the 20th century and only 140 cases were reported worldwide in the medical literature by 1898. Until the 1920s, physicians still believed that they had no chance to see lung cancer patients, so they were still obliged to observe cases that occurred! Today, lung cancer is one of the most common cancers and has more deaths than any other type

Lung cancer is one of the first diseases that has a causal relationship with smoking. Although there are reasons for lung cancer in addition to smoking, the incidence of lung cancer has become a pioneer of tobacco mediated diseases that began in the 20th century due to the main cause and influence of smoking among these diseases. . During the first decades of the last century, clinicians noticed an increase in lung cancer, and Ochsner and DeBakey (1939) told that smoking may be the cause of the case series reported in 1939 I guessed. It may be due to an artificial increase in diagnostic bias, but there is no doubt that there is a trend in the Middle Ages (Macklin and Macklin, 1940). Therefore, lung cancer is the focus of many early epidemiological studies on smoking (White 1990; Doll et al 1994). 1999)
