Stomach cancer

Stomach cancer (there is it, cancer, Stomach cancer, Gastric cancer) is cancer occurring to the stomach.
"The stomach cancer" of the wide sense includes both cancer (a stomach smooth muscle sarcoma / GIST / a stomach malignancy lymphoma) which occurred from cancer (the stomach cancer of the narrow sense) which occurred from a gastric mucosa epithelium and the organization except the epithelium, but speaks it because of the former in this clause.
It wants to be referred to each item about the cancer except it.

The stomach cancer occurs from the gastric mucosa in the reasonable inside of the tripe.
I spread to the other internal organs and a lymph node when worse, and the cancer which grew up with tripe arrives at the gullet and the duodenum.

In addition, when cancer exceeds tripe, a liver, pancreas, the large intestine infiltrate the other internal organs, and remoteness spreads to a fossa lymph node or the ovary in lungs and the collarbone.

For an organization type, internal secretion cell cancer (= high malignancy carcinoid) which internal secretion cells such as the gastrin rarely cause that most are gladular cancer (a cylinder epithelium stem cell differentiating to stomach variole and gastric glands causes it) develops it.
Cancer with both properties of gladular cancer and the carcinoid extremely rarely occurs.
In addition, leather cancer extremely rarely produces squamous cancer on the kind that there cannot be to a stomach (perhaps I assume the cell which did apparition the mother ground).

When stomach cancer forms a new tumor becoming the physical other parts from the cancer cell of the same kind in permeation / change transference, there, it is called it by a name same as a nuclear power generation tumor.
For example, when stomach cancer spread to a liver, a cancer cell in the liver is a stomach cancer cell, and the name as the disease becomes the stomach cancer liver metastasis (primary), and is not liver cancer; (however, for the histologic classification of the tumor of each internal organs which WHO performs, it is usual that an item for "metastasis characteristics tumor" or "the second-related tumor" is established conveniently).
