All types of stomach cancer can be fatal; however, If stomach cancer is found early enough, the surgeon can go in and remove the cells. It can be cured with minor surgery. Certain types have a higher risk than others. Globally, stomach cancer is the third leading cause of death from cancer.
The prognosis of stomach cancer is generally poor due to the fact that the tumor has often metastasized by the time of discovery. Most stomach tumors are malignant with evidence of spreading to lymph nodes or the liver, making treatment difficult. Cures are seldom possible after the cancer cells spread to other organs.
