What are the causes of bone cancer?
One thigh was always thicker than the other, but I didn't pay much attention. Later, pain developed, and upon examination, it was found to be bone cancer. What are the causes of this condition?

Bone cancer, referred to as osteosarcoma, chondrosarcoma, or myeloma, is a malignant tumor originating from the bones or their associated tissues. Bone cancer may be associated with the following factors:
1. Genetic factors: The occurrence of certain bone cancers is related to heredity, particularly individuals with a family history having a higher risk of developing the disease.
2. Radiation exposure: Prolonged or high-dose exposure to ionizing radiation, such as following radiotherapy, may increase the risk of bone cancer.
3. Chemical substances: Certain chemicals, such as alkylating agents, may be associated with the development of bone cancer. In addition, long-term contact with or ingestion of harmful substances, such as carcinogens found in moldy food, may also increase the risk of developing the disease.
4. Trauma and infection: Chronic minor injuries and chronic infections may increase the risk of developing bone cancer. If a fracture site is exposed to carcinogens or a wound becomes infected with harmful agents, the risk of bone cancer may also increase.
5. Age and gender: Bone cancer is more commonly seen in adolescents and young adults, with a slightly higher prevalence in males than females.
