Lung Cancer: The Unbiased Killer

Cancer is known as a fair murderer and I do not know the race, age, sex of the victim. Dr. Nader (n.d.) said that "lung cancer is the leading cause of cancer-related death in the United States" (lung cancer information). Lung cancer kills millions of people each year, but sometimes without warning. According to "The Green Sanctuary" (2009), "Cancer is often found as a small isolated mass in conventional chest X-ray or CT scan" (what is lung cancer?)

Lung cancer is a major cancer killer for men and women. In the United States, it is estimated that 169,400 new cases of lung cancer will occur in 2004, an estimated 154,900 deaths due to lung cancer will occur. Cases of lung cancer of Caucasian and African-American men appear to be decreasing, but they continue to increase among Caucasians and African-American women. There are two main types of lung cancer, non-small cell lung cancer and small cell lung cancer. Non-small cell lung cancer is more common in humans. It usually spreads slowly to various parts of the body rather than small cell lung cancer. Squamous cell carcinoma, adenocarcinoma and large cell carcinoma are three types of non small cell lung cancer. Small cell lung cancer, also known as autocellular cancer, accounts for about 20% of all lung cancers (LungUSA). Malignant tumor is cancer. Malignant tumor cells are abnormal, there is no control and order

Non-small cell lung cancer (NSCLC) is the most common type of lung cancer. Small cell lung cancer accounts for about 20% of all cases of lung cancer. If lung cancer consists of two types, it is called mixed small cell / large cell cancer. If cancer occurs from other parts of the body and spreads to the lungs, it is called lung metastatic cancer. Cause, morbidity and risk factors Higher daily smoking frequency, the faster the smoking, the higher the risk of lung cancer. There is no evidence that risk is mitigated by sucking low tar cigarettes. However, lung cancer occurs in people who have never smoked. Secondhand smoke (inhalation of smoke from other people) increases the risk of lung cancer. According to the American Cancer Society, it is estimated that 3,000 non-smokers died annually in lung cancer associated with secondhand smoke. In the following situations, the risk of developing lung cancer also increases.

In the UK, various types of lung cancer are the leading cause of cancer death among men, ranked second among women 1. I will explore the role of smoking, other environmental factors and genetic factors. Smoking is the biggest cause of preventable illness and premature death in the UK. Lung cancer was very rare in the 19th century even by 1912; Adler was only able to find 374 cases. By the 1970's, lung cancer became cancer causing the greatest cancer. The increase in lung cancer occurs simultaneously with the emergence of smoking as a large habit
