Stage 2 stomach cancer is almost always treatable, provided the actual treatment is proper. At this stage, cancer is localized in the deeper layers of tissues of the stomach and local lymph nodes but does not spread to other distant areas of the body. Treatment generally entails surgery to remove the tumor, chemotherapy, and likely radiation therapy. The overall objective is to cure this cancer and prevent it from recurring. Proper treatment means that one begins treatment as early as possible and ensures that the treatment is comprehensive to increase the probability of getting better. This is why one needs to go for checkups with the doctor occasionally for early detection and be observant of the actual symptoms.
