Central chondrosarcoma may present as osteolysis with vague borders, with or without interruption of cortical bone. Areas of x-ray opacity may be present within the tumor due to the tendency of the cartilage to calcify and ossify, and calcification often occurs around cartilage lobules without certain structure. It is characterized by irregular foggy granules, nodules or rings that are impervious to X-rays. Central chondrosarcoma is a chondrosarcoma of intraosseous origin, ranking 4th among primary malignant bone tumors, after plasmacytoma, osteosarcoma and Ewing’s sarcoma. There are distinct sites of predilection, in order of predilection, for the femur (especially proximal), pelvis, proximal humerus, scapula, and proximal tibia. What are the dietary considerations for central chondrosarcoma? Patients are advised to eat foods rich in anti-cancer elements; foods rich in high calcium; foods rich in high quality protein; spicy and stimulating foods; stimulating drinks; and foods that are easily flatulent. Asparagus: Asparagus is rich in selenium, an anti-cancer element, which prevents cancer cell division and growth, inhibits the vitality of carcinogens and accelerates detoxification, and even reverses cancer cells, stimulates the body’s immune function, promotes the formation of antibodies and improves resistance to cancer. 200-300 grams per day is appropriate. Ribs: Ribs are rich in protein and vitamins, and also contain a large amount of calcium phosphate, bone collagen and bone mucin, which can improve rich nutrients for bone cancer patients, enhance the ability to resist diseases and facilitate the recovery of the body. 230-320 grams of soup stew should be consumed daily. Milk: milk is rich in high-quality protein nutrients and also contains calcium, phosphorus, iron, magnesium, zinc and other trace elements, which can promote the absorption of intestinal nutrients, improve immunity and enhance the ability to resist diseases. 350-500 ml per day is appropriate. Avoid eating diet Chili pepper: Chili pepper is stimulating, easily stimulating the gastrointestinal mucosa, inhibiting the absorption of calcium, phosphorus and other nutrients in the gastrointestinal mucosa, reducing the immunity of the body, reducing the ability to resist disease, which is not conducive to physical recovery. It is advisable to eat light and non-stimulating food. White wine: white wine contains alcohol, which stimulates sympathetic excitation and inhibits the absorption of nutrients in the intestine, which is not conducive to the recovery of bone cancer patients. It is advisable to eat foods that promote the absorption of nutrients in the intestine. Onion: Onion is a gas-producing food, which can easily lead to gastrointestinal distension and slow down intestinal peristalsis, which is not conducive to the absorption of nutrients and affects the recovery of the body. It is advisable to eat easy-to-digest, non-gas-producing food.
