As most cancers, gastric cancer is often asymptomatic at the beginning. Even if the symptoms occur, they are often nonspecific and insignificant. You can spend a long period of time with the tumor without noticing its existence. In most cases, when symptoms finally emerge, the cancer has already metastasized to other parts of your body, which often lead to a poor prognosis.
