7 Common Causes Of Lung Cancer And How To Reduce Your Risk

The lungs play a vital role in a person’s health. When cancer occurs, the results may be devastating. Lung cancer is very common in the modern day. The current estimate given by the U.S. National Cancer Institute is that 1 out of 14 individuals will be diagnosed with lung cancer during their lifetime. Understanding some of the most common causes of lung cancer, and what you can do to decrease your risk, may save your life.


Here are 7 of the most common notable causes of lung cancer:

1 – Smoking And Second Hand Smoke

It is estimated that approximately 90% of lung cancer is caused by some form of tobacco usage. Individuals who smoke put themselves at a much higher risk than those who do not. It is also noted that those who smoke more frequently and over a longer time span are at a greater risk. Current studies have shown that one out of seven individuals who smoke at least two packs of cigarettes each day will eventually die from lung cancer or related diseases, such as mesothelioma (mesotheliomahelp.org).

Passive smoking, or second hand smoke, is also noted as a likely cause of lung cancer. This means that even non-smokers who share a dwelling with someone who smokes are at a very high risk. Recent estimates have stated that approximately 3,000 individuals die each year due to lung cancer that was caused by passive smoking.

If you smoke, or you live with someone who smokes, don’t give up hope. The sooner a person stops smoking, the sooner they can begin decreasing their risk of lung cancer and get an alternative cancer treatment. The longer a person has gone without smoking, the lower their risk.

2 & 3 – Asbestos And Radon Gas

Asbestos and radon gas are commonly noted as major contributors to many lung cancer incidents. Researchers have estimated that approximately 12% of the deaths caused by lung cancer were likely related to radon gas alone.

To reduce your risk of this exposure, make sure that your home is tested for dangerous levels of asbestos and radon gas. The tests are simple and they could save your life.

4 – Genetic Susceptibility

Genetic susceptibility, although not always provable, is often attributed to affecting a person’s risk of lung cancer. Many researchers have found a common trend between genetic susceptibility and lung cancer.

To help identify and treat problems early on, make sure your doctor is informed of any lung cancer history in your family.

5 – Disease In The Lungs

Lung disease is often related to lung cancer. If you have any form of lung disease, such as COPD (chronic obstructive pulmonary disease) stay in regular contact with your doctor to help prevent cancer growth and development.

6 – Previous Lung Cancer

Individuals who have survived lung cancer in the past are at a higher risk of developing it a second time than those who have never had it.

7 – Pollution In The Air

Over exposure to harmful air pollution may increase a person’s risk of lung cancer. Although you cannot avoid every type of air pollution, it is a wise practice to intentionally avoid overly polluted areas. It may also be a good idea to have your home inspected for any harmful pollution.
