According to the American Cancer Society, Stage IV stomach cancer is determined by whether the cancer has metastasised (spread) to other organs, nearby tissues or distant lymph nodes. It is the final stage of cancer.
Stomach cancer, also known as "gastric cancer," is estimated by the American Cancer Society to affect over 22,000 people in the United States in 2014. While causes are unknown, some of the risk factors include: gender (male), race (African-American or Asian), family history, age, A blood type, geographical location and having an H. pylori infection.
WebMD explains that some symptoms of stomach cancer are nausea, lack of appetite, bloating, indigestion, vomiting, low red blood cell count, pain in the abdominal region (typically above the navel) and fluid build-up in the abdomen. Stomach cancer is best treated when found in the early stages, although symptoms often are not present until the later stages. Typical treatments are chemotherapy, radiation and/or surgery.
