Lung Cancer: Sypmptoms And Prevention


Lung cancer is a type of cancer that begins in the lungs. It is a condition that causes cells in the lungs to divide uncontrollably. This causes tumor growth that reduces a person’s ability to breathe.

It is the leading cause of cancer death among men and women in the united states. According to the World Cancer Research Fund, there were over two million new cases in 2018, resulting in a whopping 12.3% of all cancers diagnosed in the year.

There are typically two most common types of lung cancers which are Small Cell Lung Cancer (SCLC) and Non-Small Cell Lung Cancer (NSCLC). NSCLC accounts for nearly 90% of all lung cancers diagnosed and typically grows at a slower rate than SCLC.


Symptoms Of Lung Cancer

Prevention Of Lung Cancer

Different types of cancers are caused by different factors. For lung cancer, reseachers continue to look into factors that might cause it and also ways to prevent it.  At the moment there are no proven ways to completely prevent the disease but certain habits might help lower the risk. The most effective prevention is to stop smoking and eliminate exposure to tobacco smoke. People who never smoke have the lowest risk of the disease. Minimizing exposure to passive smoking is also an effective prevention measure.

Avoid Tobacco or Smoking

Smoking damages cells in the lung, causing the cells to grow abnormally. According to the Centers for Disease Control and Prevention cigarette smoking causes about 80% to 90% of lung cancer deaths in the United States. If you smoke the best way to prevent lung cancer is to stop smoking. Every year you don’t smoke lowers your risk of the disease.

Avoid SecondHand or Passive Smoking

Avoid where smoking occurs, regular exposure to smoke from someone else’s cigarettes, cigars, or pipes increases a person’s risk of lung cancer. The U.S Surgeon General estimates that living with a person who smokes increases the chance of lung cancer by 20% to 30%. research also suggests that secondhand smoke exposure may increase the risk of other cancer (cervical cancer, kidney cancer, rectal cancer) by at least 30%.

Avoid Radon

Radon is an odorless gas naturally released by some soil and rocks. According to radon is the leading cause of lung cancer after smoking and the number one cause of lung cancer in non-smokers. The U.S Environmental Protection Agency recommends that all homes should be tested for radon.

Be Careful At work and Home

Prevention is important at both the home and office. Substances like gases or chemicals can increase a person’s risk. Be careful with wood smoke from wood-burning stove or coal. Diesel gas fumes or fumes from soldering metals are substances to be careful with.
