Stomach cancers also called upper gastrointestinal (UGI) cancers happen in the organs that are found in the upper section of the digestive system. The UGI organs of the digestive system (how we eat and process food) include:
- Oesophagus – the tube or pipe food travels down from the mouth into the stomach
- Stomach – where chewed food meets gastrc juices and is further broken down (digested)
- Pancreas – where enzymes that help digest food are made as well as hormones such as insulin
- Liver – which has many jobs such as making bile (fluid) that helps break down fats in food, store sugars that bodies need as fuel, and helps process alcohol, medicines and some poisons to remove them from the body.
- Gall bladder – a small organ next to the liver that helps make and store bile that is used for the breakdown of food.
- Small intestine – where digested food from the stomach travels to and is further processed with the help of enzymes from the pancreas and bile from the liver. This intestine is where most of the nutrients from the food are absorbed and taken to the bloodstream for use.
