How to help with stomach cancer?
Some people might be helped by the placement of a feeding tube. If it is only needed for a short time, a thin tube can be passed down the nose and throat and into the stomach or intestine. If a feeding tube is needed for a longer time, a minor surgical procedure can be done to place the tube through the skin of the abdomen and into either the lower part of the stomach (a gastrostomy tube or G tube) or the small intestine (a jejunostomy tube or J tube ). Liquid nutrition can then be put directly into the tube.
How to treat a tumor in the stomach?
For example, a laser beam directed through an endoscope (a long, flexible tube passed down the throat) can destroy parts of the tumor to stop it from blocking the passage of food through the stomach. If needed, an endoscope can be used to place a stent (a hollow metal tube) where the esophagus and stomach meet to help keep it open and allow food to pass through. This can also be done at the junction of the stomach and the small intestine.
What is the treatment for cancer?

What is therapy resistance?
Therapy resistance is thought to be driven by a small number of “cancer stem cells.” Standard chemotherapies don’t specifically target these cells, so they tend to survive and allow the cancer to regenerate itself over time, leading to relapse.
