What is Lung Cancer?

Lung cancer is a malignant tumor that develops in the cells of the lungs. When you are diagnosed with lung cancer, you want to be getting treatment as soon as possible, because it can spread throughout your body, it does this when cells start breaking off the tumor and travel through the blood stream or through the vessels and end up in different regions of the body. It can spread to your lymph nodes, bones, brain, and liver. If it has spread to your lymph nodes, you might notice a lump in your neck, or armpit. If nodules occur in your neck, going to the hospital to get an ultrasound, and biopsy would be an effective way to check if the lump is benign or malignant.

There is two different types of lung cancer: small cell carcinoma, and non-small cell carcinoma. Non-small cell is characterized into four different types: Squamous lung cancer, adenocarcinoma, large cell carcinoma, and unclassified/undifferentiated. Squamous carcinoma is the most common form of lung cancer, and is usually more common with smokers. It forms in the major airway, and then moves into the tissue, and then will spread into the bloodstream. Adenocarcinoma is a tumor that appears below the lining of the airway, and can spread to the lymph nodes and even into the blood. Carcinoma is a very rare form of lung cancer, it develops from the hormone-producing cells. This form of lung cancer usually effects younger people. Small cell carcinoma is also called ‘oat cells’ because they look similar to grains of oats, they are also very tiny and delicate.
