Lungs Cancer Definition

Lungs cancer Definition:

To put it simply, lung cancer is the uncontrollable growth of irregular cells. Abnormal cell growth can be caused by a number of factors. Cancerous cells that do not function like normal lung cells can harm surrounding healthy lung tissue. This is what causes the symptoms of lung cancer.

Lung cancer is obviously cancer of the lungs. When a cell divides itself into two cells, the DNA of the cancer cell is replicated which further spreads cancer. Lung cancer usually begins when cells encounter an error in its DNA. Also called mutations, these errors make the entire cell stop working correctly. When mutated cells duplicate, cancer spreads.

What causes lung cancer?

After learning about Lungs cancer definition, we will now discuss lung cancer causes. Mutations and acquired genes can be the cause of lung cancer. If there is a family history of cancer, the genes may be passed down hereditarily. Mutations can be the result of being exposed to certain chemicals. The chemicals in cigarettes have been proven and are known to cause lung cancer. Radon gas is the leading cause of lung cancer for non-smokers. So, no one is completely safe from the spread of mutated cells. Lung cancer can be developed in smokers and non-smokers alike. However, heavy smokers are considered to be at a much higher risk of getting lung cancer.

Also, second-hand smoke is responsible for many lung cancer deaths in the United States. Roughly 3,000 people every year die from lung cancer caused by second-hand smoke.

The Dangers of Lung Cancer

Out of every form of cancer, lung cancer leads the number of yearly deaths in the United States. Lung cancer is the uncontrollable growth of mutated cells. When these mutated cells cluster together they form what is called a tumor. Tumors can be benign or malignant, but when dealing with lung cancer most tumors are malignant. Exposure to dangerous chemicals and carcinogens cause the mutation of cells.

Without treatment, the average life expectancy of someone diagnosed with lung cancer is only 2 to 4 months. Even with treatment, lung cancer in its later stages is very hard to cure. Most only live about 6 to 12 months. It is important that lung cancer is found before symptoms appear. If lung cancer is found early enough, the diagnosed patient could live past the overall 5-year survival rate. Early stages of lung cancer are relatively easier to cure.

Without a doubt, lung cancer is dangerous. The best way to beat lung cancer is to catch it before it is too late. A person could have lung cancer and not even know it. This is when it needs to be found and treated. Once symptoms start appearing, a diagnosed patient’s survival rate drops. Coughing up blood and shortness of breath are dangerous signs of cancer spreading.

Lung cancer is dangerous and the only way to truly be safe from it is to avoid any chemicals or carcinogens that cause it. Lowering the risk of getting lung cancer still does not fully prevent it. Anyone can develop lung cancer, which is what makes it one of the most dangerous diseases in the world.
