LUNG CANCER
Lung cancer - Overview
The cells that line the inner mucosal layer of the stomach are the source of gastric cancer. In order to spread to lymph nodes and distant organs including the liver, lungs, and peritoneal surfaces, it first invades the muscular and serosal layers of the stomach.
Lung Cancer - Overview
Lung cancer is a type of cancer that begins in the lungs and develops because of the uncontrolled growth of abnormal cells. Growth of these abnormal cells can interfere with normal lung function. The abnormal cells can pass from the original part of the lung to other parts of the body, such as the opposite lung, our lymph nodes, bones, liver and more.
There are two main types of lung cancer:
-
Non-small cell lung cancer (NSCLC): NSCLC accounts for approximately 85% of all lung cancers and arises from a type of cell that lines the surface of organs (epithelial cells). Types of NSCLC include adenocarcinoma, squamous cell carcinoma and large cell carcinoma.
-
Small cell lung cancer (SCLC): SCLC accounts for 15% of all lung cancers and is strongly associated with cigarette smoking. It grows and spreads quickly to other parts of the body, including the lymph nodes.
Lung Cancer - Symptoms
Early-stage lung cancer may not cause any noticeable symptoms.
Common symptoms of lung cancer at a more advanced stage include:
-
Persistent cough that gets worse over time
-
Shortness of breath
-
Blood in the sputum
-
Constant chest pain (may occur in association with a chronic cough)
-
Recurrent chest infection and fever
-
Weight loss
