What are the early signs of bone cancer?
Disease description:
I occasionally had leg pain before but didn't pay much attention to it. Recently, the leg pain has become severe, and after examination, I was diagnosed with bone cancer. What are the early signs of bone cancer?

The early signs of bone cancer mainly include the following aspects:
1. **Pain and Tenderness**: In the early stages, bone cancer may present as intermittent mild pain. However, as the disease progresses, the pain gradually intensifies and may become persistent and severe, particularly at night. The affected area may also be tender to touch.
2. **Local Mass and Varicose Veins**: As the tumor grows, a localized mass may become palpable. Additionally, tumor compression can lead to the development of varicose veins in the affected area.
3. **Systemic Symptoms**: Patients with bone cancer may experience systemic symptoms such as fever, loss of appetite, weight loss, fatigue, and reduced physical capacity. These symptoms may worsen as the disease progresses.
It should be noted that these symptoms are not necessarily indicative of bone cancer and may also be signs of other diseases. Therefore, if any of these symptoms occur, prompt medical consultation and professional evaluation are recommended for accurate diagnosis and treatment.
