Lung cancer is among the most common types of cancers in both men and women worldwide. According to the U.S. National Cancer Institute, approximately one out of every 14 men and women in the U.S. will be diagnosed with lung cancer at some point in their lifetime. In the U.S., lung cancer has surpassed breast cancer as the most common cause of cancer-related deaths in women. But being aware of the risk factors and paying attention to warning signs and symptoms can save life.

Risk factors

Smoking – There is a strong link between lung cancer and cigarette smoking, and about 90% of lung cancer cases are a result of tobacco use. The risk of lung cancer increases the more cigarettes you smoke and the longer time you smoke. It is believed that among smokers of two or more packs of cigarettes per day, one in seven will die of lung cancer.

Passive smoking – You don’t have to be a smoker yourself to put your health at risk. Tobacco smoke contains many chemicals that have been shown to be carcinogenic. The risk increases the more you are exposed to cigarettes smoked by the other people.

Air pollution – It is believed that prolonged exposure to highly polluted air can increase the risk of developing lung cancer similar to that of passive smoking.

Asbestos fibers and other chemicals – asbestos use is limited or banned in many countries, but was widely used in the past. This includes also exposure to certain chemicals and substances that are used in several occupations and industries such as arsenic, beryllium, cadmium, coal, silica and nickel.

Radon gas – This is a natural radioactive gas that is a product of uranium. It is invisible and odorless and can come up through soil and enter the house.

Heredity – Individual genetic susceptibility may play a role in getting lung cancer. Also people with a family member with lung cancer have an increased risk of the disease.

Lung diseases – Certain lung diseases are associated with an increased risk for developing lung cancer, such as COPD and scarring of the lung.

Over 65 years of age – Almost 70% of people diagnosed with lung cancer are over 65 years of age, whereas less than 3% of lung cancers occur in people under 45 years of age.

Signs and symptoms of lung cancer

Warning signs of lung cancer are not always present or easy to identify. In many cases lung cancer may not show any noticeable symptoms in the early stages. But if you suspect that some of the risk factors apply to you, then early screening may help people at high risk for the disease.

A person with lung cancer may have the following symptoms:

1. Persistent cough or changes in cough

If you have a cold, your cough should go away after a week or two, but if it persists over a long time, you should see your doctor. If you are a smoker or suffers from chronic cough, notice if there are any changes in your chronic cough, for example: coughing more frequently, deeper cough with a deeper or hoarse sound, coughing up blood or having more mucus than usual.

2. Shortness of breath

If you are short of breath while doing a task that you could have done easily in the past, it may be a symptom of lung cancer. This symptom can occur if lung tumor blocks or narrows an airway, or if fluid from it builds up in the chest.

3. Chest and bone pain

One of the symptoms of lung cancer may be pain in the chest, shoulder, or back area. Lung cancer that has spread to the bones may cause pain at the sites of the affected bone. If it has spread to the brain it may cause a number of neurological symptoms and headaches. So listen to your body and if the pain persists and doesn’t go away, go to see your doctor.

4. Wheezing

While a whistling sound when you breathe can result from asthma or allergies, it can also be associated with lung cancer. If wheezing persists, visit your doctor to find the cause of it.

5. Voice changes

Your voice becomes hoarser and deeper or you notice any other significant changes in your voice. While hoarseness can result from a simple cold, if it persists then go to see your doctor.

6. Persistent chest infections 

Infections such as bronchitis and pneumonia that don’t go away or keep coming back.

7. Weight loss, loss of appetite, fatigue and weakness

These are non-specific symptoms that can be seen with many other cancer types or other diseases, but if the changes are unexplained and persist, then go to your doctor to find the cause of it.

How to reduce the risk for developing lung cancer

  • Stop smoking if you haven’t done it yet.  You can read my previous article about 5 natural ways to quit smoking that have been scientifically proven. If you are a passive smoker, eliminate your exposure to tobacco smoke.
  • Test your home for radon – If you suspect you have radon gas in your home, buy a home radon test kit that can identify increased radon levels in the home.
  • Avoid carcinogens at work – Take precautions to protect yourself from exposure to toxic chemicals at work.
  • Other lifestyle changes – There is strong evidence to suggest that regular exercise can lower the risk of developing lung cancer and other types of cancer. Also eat a high fiber diet with lots of fruits and vegetables. There is also evidence that this vegetable can reduce the risk of lung cancer. You can also read my article about the top 14 foods that protect against cancer development.
  • Early scanning – Chest X-rays are not effective in detecting early-stage lung cancer. However, low-dose CT scans have been shown to reduce lung cancer mortality by 20%.

  1. I think mine (found by a CT scan) was caused by the dust kicked up through my room heater, which produced a cough when the heater was on. I’m trying easy fixes first. I moved the heater so it doesn’t blow close to or directly at my bed. I bought an industrial air cleaner. I plan to change the location of the heater again from the floor to a higher spot where the air intake is more free from dust. I also plan to clean and reduce available dust. Second, I’m trying some anti-cancer remedies including vitamin D3, Potassium Iodide, and Turmeric. I hope to give all this a good try before allowing a doctor to remove the affected lobe of lung. Also prayer can work.

      I went to a nursery and bought my tree, then went on line and bought a bag of crushed leaves and I put them in gel caps and take 2 to 3 a day. I don’t have cancer, at least I don’t think I do ….but the trees are so good for you, I did buy three more trees and have them planted in my yard and they are growing pretty good..

    For Kirk W. Fraser & others that choose to use natural treatments than medical drugs & the kind..
    My aunty was told to drink special green coconut that has pink or young purple color inside. Burn the coconut in the flame for 15 minutes, and serve it as usual.
    One coconut/day, drink it before sleep at night, for 3 days (we can drink it regularly).
    It is to clear up the toxins inside her body.
    And then, she started with 1st to 14th day boiling 7 to 33 leaves of sour soup leaves (2 leaves added each day) with 2 glass of water became 1 glass, made that 3 times to be drank in the morning, noon & night.
    And after that couple weeks, she just have to drink 9 leaves, twice a day, everyday, regularly.
    Until her doctor said, she was really in healthy condition, with dissapeared cancer.
    Like a tv show said, “Believe it, or not”.
    And of course, she keeps her huge high diet continued.
    Hope this is useful.
