The most viable treatment options for gastric cancer right now are surgery, chemotherapy, radiation therapy, and immunotherapy. Chemotherapy uses drugs like cisplatin and fluorouracil, and radiation therapy employs high-energy rays to target cancer cells. Although these treatments are most popularly used, they have significant limitations. Some side effects include toxicity, resistance, and limited effectiveness. In many cases, treatment also needs advanced personalization based on disease characteristics; this can often be costly and inaccessible for most patients.
