Lung cancer is cancer that begins in the lungs and can spread to other parts of the body. It is the top cause of cancer death in men and women in the US. It is also one of the most preventable types of cancer. By not smoking or being exposed to second-hand smoke, lung cancer can be prevented.

The disease usually starts in the spongy, pink, and gray walls of the lungs air sacs or bronchioles. There are more than 20 varying types of lung cancer, but the two main types are non-small cell cancer and small cell lung cancer.

Adenocarcinoma is probably the most common type of non-small cell lung cancer. It happens mostly to those who smoke, and it makes up 40% of all lung cancers. More women then men get this type of cancer, and people who get it tend to be younger than with other kinds of cancer.

Squamous cell carcinoma almost always starts in the central bronchi or the largest branches in the lungs. This typically happens in 30% of lung cancer cases. It is the most common in men who smoke. These types of cancers can spread to the lymph nodes, bones, and other organs.

Large cell carcinomas are cancers that have large cells, and they tend to form along the lungs outside edges and only account for 10-15% of all lung cancer cases. They tend to grow faster than other types of cancers, and they quite often will spread to the lymph nodes, bones, and brain.

Small cell lung cancer is the most fast-moving and aggressive form of cancer. They start in the large branches of the lungs, and it spreads very quickly, most times before symptoms even first appear.

There are many signs of lung cancer, and it’s essential to catch them as soon as possible since lung cancer can remain hidden for a while before symptoms are noticeable.
