Early detection is always crucial in effective treatment. As a matter of fact, early-stage or stage I stomach cancers can usually be easily removed from the stomach’s inner lining without any complications. Still, if the tumors grow into the muscle layer of the wall, other approaches might be recommended, or more intricate surgeries may be required.
In the case of later-stage (stage II and III) cancers, experts may recommend chemotherapy and radiation therapy as treatments to shrink the tumors. This might also make their removal easier. Still, in these cases, surgery will most often involve removing at least some of the lymph nodes and a considerable part (if not all) of the stomach.
In cases of stage IV stomach cancer, the tumors have spread to nearby organs, and surgery might not be an option anymore, or other treatments will be used first to shrink the tumors, but parts of the affected nearby organs are removed as well.
