Lung cancer is the second most common form of cancer in the world, having claimed more than 158, 040 lives in the United States alone in 2015. There is a need to spread awareness of what the symptoms, treatment options, and resources are available for lung cancer patients. Having decision aids that concisely explain everything essential in an organized fashion is what is needed in order to help patients make the most difficult decision of their lives. Knowing what is available and works best for you is important, as lung cancer devastatingly affects your health.

What is lung cancer?

Lung cancer is one of the most common cancers in the world. Similar to how the physiological origin of this chronic disease begins, this particular type of cancer manifests in the lungs of the human body. The lungs start producing abnormal cells which then affect the oxygen flow in one’s body. Lung cancer is categorized into three different types: (1) non-small cell lung cancer; (2) small cell lung cancer; and, (3) lung carcinoid cancer. According to the National Institute of Health’s National Cancer Institute (2014), lung cancer is the second most common cancer and the primary cause of cancer-related death in both men and women in the United States.


What are the differences between the three types of cancer?

  1. Non-small cell lung cancer: According to the American Cancer Society, this is the most common type of lung cancer. This particular type of lung cancer produces approximately 85% of the reported deaths of lung cancers.
  2. Small cell lung cancer: According to the American Cancer Society, approximately 10-15% of lung cancers are small cell lung cancers, which are known to grow and spread quickly.
  3. Lung carcinoid tumor: According to the American Cancer Society, this particular type of lung cancer is the rarest of the three types of lung cancers because there are fewer than 5% cases of this lung cancer.

How many people are affected by lung cancer?

In 2015, the American Cancer Society has stated an estimated a total of 221, 200 new cases of lung cases (115, 610 in men and 105, 590 in women) and approximately 158,040 reported deaths (86, 380 in men and 71, 660 in women). Every year more deaths are caused by lung cancer (non-small cell and small cell) alone than that total number of deaths in colon, breast, and prostate cancer combined.

The American Cancer Society has also stated that there are about 4, 000 (which is about 1% to 2% of all lung cancers) new cases of lung carcinoid. There is also an observation that people around 60 years are typically diagnosed with lung carcinoid cancer.

What are some of common risk factors for lung cancer?

According to the American Cancer Society, a risk factor is defined as anything that affects a person’s chance of getting a disease such as cancer.

There is a list of risk factors on the American Cancer Society’s website:

  1. Tobacco Smoke: If an individual smokes cigars, pipes, low-tar or light cigarettes, or menthol cigarettes, he or she is at a greater risk than those who do not smoke. According to the American Cancer Society, at least 80% of lung cancer deaths result from smoking.
  2. Secondhand Smoke: Even if you do not have a smoking habit, surrounding yourself around and breathing in others’ smoke increases your risk of developing lung cancer by about 30% (The American Cancer Society, 2015).
  3. Radon: According to the American Cancer Society, radon is a naturally occurring radioactive gas that results from the breakdown of uranium in soil rocks; this gas cannot be seen, tasted, or smelled. According to the US Environmental Protection Agency (EPA), radon is the second leading cause of lung cancer in America, and it is the leading cause among non-smokers.
  4. Asbestos: Asbestoses are fibers existent in mines, mills, textile plants, places where insulation is used, shipyards, etc. Those who smoke, breathe in, and work in any of the aforementioned places are at a much higher risk for lung cancer than those who experience them separately.
  5. Air or radioactive chemical pollution in a workplace environment:
    1. Radioactive ores such as uranium
    2. Inhaled chemicals or minerals such as arsenic, beryllium, cadmium, silica, vinyl chloride, nickel compounds, chromium compounds, coal products, mustard gas, and chloromethyl ether
    3. Diesel exhaust
  6. Personal or family history of lung cancer

For more information and details on the risk factors for lung cancer, please see the following document from the American Cancer Society:

And, remember to quit smoking and/or encourage loved ones to give up their cigarettes, not only for their sake but also for yours.

What are some of the common symptoms of lung cancer?

According to, the following symptoms of lung cancer occur in the chest:

  1. Coughing, especially if it persists or becomes intense

  5. Changes in the voice or being hoarse
  6. Harsh sounds with each breath (stridor)
  7. Recurrent lung problems, such as bronchitis or pneumonia
  8. Coughing up phlegm or mucus, especially if it is tinged with blood
  9. Coughing up blood

According to, the following symptoms of lung cancer may occur elsewhere in the body:

  1. Loss of appetite or unexplained weigh loss
  2. Muscle wasting away (also known as cachexia)
  3. Fatigue

Digital Tools From the Google Play Store

Lung TNM Calc

Rating: 4.7 Stars

Downloads: 10,000

This app is helpful for determining what treatment plan should be best for specific stages of cancer. However, there are two weaknesses to this app. First, the app’s overall design is not as user-friendly as the background. Secondly, the terminology presented in the app is only understandable to medical professionals, not to common laymen. This app may be great for medical professionals to utilize, but the public would not be able to use this app without constantly having to search what the terms in the app mean.
