Omega-3 fatty acids, found in fish oil, have strong protective effects against cancer and its complications. Studies show these healthy fats can help control abnormal cell growth in cancer patients. Omega-3s act as antioxidants, reduce inflammation, and even inhibit tumor cell growth. They also support mental well-being in cancer patients by providing neuroprotective benefits. By including omega-3 polyunsaturated fatty acids in their diet, cancer patients can potentially improve their health and quality of life.
