Stomach (Gastric) Cancer Screening (PDQ®): Screening - Patient Information [NCI] - What is screening?
Screening is looking for cancer before a person has any symptoms. This can help find cancer at an early stage. When abnormal tissue or cancer is found early, it may be easier to treat. By the time symptoms appear, cancer may have begun to spread.
Scientists are trying to better understand which people are more likely to get certain types of cancer. They also study the things we do and the things around us to see if they cause cancer. This information helps doctors recommend who should be screened for cancer, which screening tests should be used, and how often the tests should be done.
Staging has an important role in determining the most effective treatment for soft tissue sarcoma. Clinical staging involves magnetic resonance imaging (MRI) or computed tomography (CT) of the primary tumor area and a chest CT to look for metastasis to the lung (the most common site of distant spread). An abdominal CT scan is done in the case of retroperitoneal sarcomas because the liver may be the site of initial clinical metastasis for these tumors.
The stage is determined by the size of the...
