Up to 90% of all human cancers are circinomas, which are growths that originate in epithelium. Most carcinomas begin on surfaces that contact the external enviroment, such as skin, linings of the airways in the respiratory tract, or linings of the stomach or intestines in the digestive tract. This observation suggests that the more cancer causing agentsmay not penetrate tissues very deeply.

What is the difference between small and large cell cancer?

My husband was just diagnosed with secondary liver cancer. I would like to know what is the difference between small cell and larger cell cancer. This is refering to small cell and large cell lung cancer, so I don't know how helpful it'll be: Small cell lung cancer is called this because the cancer cells are small cells that are mostly filled with the nucleus. Small cell cancer spreads early on, so radiotherapy, rather than surgery, is suggested. Large cell lung cancer is called this because the cells look large and rounded. This type of cancer spreads more quickly. source: http://www.cancerhelp.org.uk/type/lung-cancer/about/types-of-lung-cancer#large
