Patients with osteosarcoma are advised to follow a light diet and eat more vegetables. Fruits should mainly consist of common ones, including apples and other fruits. Although mango is a tropical food and can be consumed occasionally without major impact, it is still advisable to avoid excessive consumption. It is also appropriate to consume some nutritional health foods, such as multivitamins or high-quality protein powder, which can better enhance one's immunity. Additionally, it is important to maintain a joyful mood. The diet should primarily avoid spicy and irritating foods, as well as bad habits like drinking alcohol, smoking, and staying up late.
