Lung Cancer

Lung cancer starts in the lungs of a human body but can expand to other parts of the body. This type of cancer causes the majority of deaths, despite the fact that lung cancer is one of the most preventable. Smoking is the reason for 85% of all lung cancer cases, even though the condition may develop if one has familiar predisposition, lung disease or exposure to radon gas, asbestos and other carcinogens.

Types of Lung Cancer

There are two main types of the condition, depending on the appearance of lung cancer cells:
Small cell lung cancer: usually appears in heavy smokers and is less common.
Non-small cell lung cancer: is a term for various types of lung cancer, including cell carcinoma, adenocarcinoma and large cell carcinoma.

Symptoms of lung cancer

Early stages of lung cancer do not exude any symptoms, which can be misleading when detecting the condition. Anyways, when lung cancer starts to develop the symptoms are the following:

  • Chest pain
  • A lost-lasting cough
  • Coughing up blood
  • Shortness of breath
  • Hoarseness
  • Pain during swallowing
  • Weight loss
  • Fatigue
  • Loss of appetite

Is lung cancer genetic?

As a matter of fact, the majority of lung cancers are related to tobacco smoking, but a great number of nonsmokers suffer from the condition as well, which may be caused by genetic susceptibility. If somebody from your family tree suffered from lung cancer, there is a risk of developing the disease in the future, as the presence of the gene mutation in your DNA is high.

Should I get tested?

The genetic test is able to calculate your risks of developing the condition in the future, which is essential, especially if the disease is common in your family. Knowing your likelihood beforehand will help you to take steps to the risk reduction or complete prevention of the disease, changing your lifestyle and daily habits.
