Lung cancer is the biggest cause of cancer deaths in the United States and the rest of the world. It involves a tumor growth within the lungs, reducing lung capacity and affecting breathing. We currently know that it is caused primarily by cigarette smoking, but it can also occur as a result of passive smoking or being exposed to pollution or general smoke for long periods of time.
Lung cancer will also occur as a result of cancers from the rest of the body spreading and reaching the lymph nodes, resulting in cancerous cells spreading across the body and causing tumors elsewhere in the body.
There are actually two types of lung cancer – small cell lung cancer, and non-small cell lung cancer.

The first thing you’ll notice is that you can’t stop coughing. This isn’t the usual cough that you might experience with a cold or flu, but a deep, chronic cough that comes deep from your chest. It will sound hoarse and will constsantly happen. You will feel like there is no relief from the cough, it will feel dry and particularly uncomfortable each time you do it.
Over time, it can also create a scratching pain in your chest.
