Osteosarcoma is a relatively rare type of bone tumor that primarily affects adolescents and young adults. Early detection and treatment are crucial for improving cure rates and survival. Below are six early warning signs of osteosarcoma:

1. Bone Pain: This is the most common symptom. Early on, it may present as intermittent pain that gradually intensifies as the disease progresses, particularly at night.

2. Lumps: In the early stages of osteosarcoma, lumps may appear at the tumor site, which are typically firm in texture with unclear borders.

3. Restricted joint movement: As the tumor grows, it may affect the normal movement of the joints, leading to restricted joint function.

4. Fatigue and weight loss: Patients with osteosarcoma may experience systemic symptoms such as fatigue, weakness, and weight loss.

5. Fever: Osteosarcoma can cause fever, particularly when the tumor damages bone and leads to infection.

6. Pathological Fracture: The bone at the tumor site may become fragile due to erosion by the tumor, making it prone to fractures.

Preventing Osteosarcoma, Traditional Chinese Medicine Recommendations:

1. Healthy Diet: Maintain a balanced diet by eating plenty of fresh vegetables and fruits while avoiding spicy, greasy, grilled, and similar foods. Traditional Chinese Medicine believes that a reasonable diet helps maintain organ function and prevents the internal production of pathological substances.

2. Emotional Regulation: Maintain a positive mindset and avoid excessive emotional fluctuations. Traditional Chinese Medicine holds that emotional disturbances are a significant cause of illness.

3. Moderate Exercise: Appropriate physical activity can enhance physical fitness and boost the body's immunity. Traditional Chinese Medicine recommends exercises such as Tai Chi and Ba Duan Jin, which help regulate qi and blood and maintain physical health.

4. Avoid Environmental Pollution: Try to minimize prolonged exposure to harmful chemicals and radioactive materials. Traditional Chinese medicine believes that these harmful substances can damage the body's vital energy (Zhengqi), leading to dysfunction of the internal organs.

5. Regular physical examinations: Especially for individuals with a family history of osteosarcoma or abnormal bone development, regular bone examinations are recommended for early detection and treatment.

6. Traditional Chinese Medicine (TCM) Regulation: Based on individual constitution and symptoms, under the guidance of a TCM practitioner, some traditional Chinese herbs with effects such as clearing heat and detoxifying, promoting blood circulation and removing blood stasis, and replenishing vital energy can be selected for regulation.

In summary, understanding the early signs of osteosarcoma, seeking medical examination promptly, and combining TCM prevention and treatment methods can effectively reduce the risk of developing osteosarcoma and improve treatment outcomes. Traditional Chinese medicine emphasizes holistic regulation and syndrome differentiation treatment, aiming to maintain internal and external balance in the body and prevent the invasion of pathogenic factors through lifestyle adjustments. Through various methods such as dietary regulation, emotional balance, moderate exercise, and regular routines, combined with TCM constitution identification and herbal regulation, the risk of developing osteosarcoma can be effectively reduced.
