The worst-case scenario is that it kills you, obviously.

What Is Lung Cancer?
Lung cancer occurs when the cells in your lungs stop acting like they’re supposed to. 

The cells are supposed to die and be replaced periodically, but with lung cancer, the new cells are created early; the old cells don’t die when they should, and you end up with an excess of cells that then group together to form a tumor.

Lung cancer can cause a very slow and painful death. To minimise your chances of suffering from it, avoid chemical exposure, smoking and breathing in second-hand smoke.

What Are The Symptoms And Effects Of Lung Cancer?
Someone with lung cancer will show different symptoms, depending on what stage the cancer is at and whether or not it has spread to other parts of their body. Here are some of the most common symptoms:

  • A persistent cough that just keeps getting worse
  • Coughing up blood or strange-colored mucus
  • Intense chest pains
  • Fluid on the lungs
  • Difficulty breathing
  • Fatigue and lethargy  (feeling like you have no energy)
  • Weight loss (without any known cause)
  • Headaches
  • Nausea
  • Pain
  • Hoarse, wheezy voice

Lung cancer changes normal lung tissue into abnormal lung tissue which doesn't function like normal lung tissue.

Consequently, the patient doesn't get the benefit of absorbing oxygen and getting rid of carbon dioxide. This is like slow, prolonged, worsening suffocation.  Then you die.

Lung cancer will slowly suffocate you or make you feel you can't breathe. It will also spread very quickly throughout the body. I pray this isn't you or someone you know.
