3. NSCLC Tumors
NSCLC has three types of tumors which differ from each other because of the different lung cells they initially form in. These tumors manifest themselves differently. They are grouped together though as they are commonly found in NSCLC patients. The first is Adenocarcinoma. This type of tumor forms in the glands which secrete mucus and other substances in your lungs. Although it falls under NSCLC, it is quite common to find in smokers and in other cancers like pancreatic and prostate.
The second is Squamous cell or also Epidermoid carcinoma. This cancer form begins with thin flat cells lining the airway of the lungs from the inside. This tumor can also spread and even begin different regions in the body including the liver, brain, spine and other bones. The third is the Large Cell Carcinoma. It is relatively faster in how it forms in the body and spreads much faster making it the most difficult to treat.
