Gastrointestinal (GI) cancer refers to tumours of the oesophagus, pancreas, stomach, colon, rectum, anus, liver, biliary system, and small intestine that affect the gastrointestinal tract and other organs located within the digestive system. When the cells lining one or more of the organs in the digestive tract change and begin to grow, tumours form, and the cancer can spread to the lymph nodes and other organs. Patients with early-stage GI cancer may not experience any symptoms. It's also practically hard to feel gastrointestinal tumours as they grow. As a result, GI malignancies are frequently detected in screenings prior to the onset of symptoms. Or they're diagnosed after they've progressed to the point where they're producing more serious symptoms.
Hepatocellular carcinoma (HCC) is a type of cancer that begins in the liver. It's not the same as "secondary" liver tumours, which have moved from other organs to the liver. It can sometimes be treated with surgery or transplantation if discovered early. Although it cannot be cured in more severe cases, treatment and care can help the patient live longer and better.
