If bone metastasis occurs, it is usually an advanced stage of cancer, but patients can prolong their survival time through active treatment. Bone metastasis refers to the malignant tumor having distant metastasis through the blood channel, indicating that the cancer cells have spread, which is clinically considered as advanced stage of cancer. At the same time, most of the patients will suffer from severe anemia, emaciation, local severe pain, etc. Pathological fracture may also occur, and at this time, the patients’ physical condition is poor. However, if the site of bone metastasis does not affect normal activities, then after active anti-tumor and anti-bone metastasis treatment, it is possible to prolong the survival period. When patients have bone metastasis, they should seek medical treatment in time and under the guidance of professional doctors to improve the quality of life and prolong life.
