Gastric Cancer Stages
Once the cancer is found in your
stomach, the next step is to stage it or find out the extent of the tumor. For this, your physician may perform
X-rays, ultrasounds and CT scans. In general, gastric cancer progresses in the following stages:
in situ (CIS) - the cancer has not spread beyond the lining of the stomach
I – a stage 1
gastric cancer is not aggressive; the chances of recovery is high. The tumor is found in the layer of
tissue that lines the inside of the stomach. Although rare, cancer cells can spread to nearby lymph nodes.
II - although a stage 2
gastric cancer is still not aggressive, the tumor has spread into the muscular layer of the stomach
wall; lymph nodes may also be affected.
III - at
this stage, the cancer has become aggressive and invaded all layers of the stomach wall; the tumor has also
spread into lymph nodes.
IV – a
stage 4 gastric cancer is very aggressive. The tumor has affected not only the tissue of the stomach
but also nearby structures. In some cases, the cancer cells can travel to the spleen, liver, bone, lung
has returned after initial treatment.
