It is not scientific to say that osteosarcoma is more terrible than cancer. From the incidence rate, clinical symptoms, survival rate and other aspects, it can be seen that osteosarcoma is not more terrible than cancer. 1. Incidence rate: the incidence rate of osteosarcoma in bone tumor is about 3 per million, the incidence rate is very low, accounting for malignant tumors only about 0.2%. Compared with other malignant tumors, the incidence rate of bone tumor is relatively low. From this point of view, osteosarcoma is not more terrible than cancer. 2. Clinical symptoms: the clinical symptoms of osteosarcoma will cause joint swelling, joint pain, flexion and extension of the body and other symptoms, the deterioration of the disease will lead to anemia, weight loss, fever and limp and other symptoms. Cancer will cause hemoptysis, vomiting blood, fever, fatigue and severe pain, etc., which will affect the quality of life and even shorten the life of patients, osteosarcoma is not more terrible than cancer. 3. Survival rate: Osteosarcoma is a highly malignant tumor of bone origin, if standardized treatment, the 5-year survival rate of patients is about 70%, but in the 1970s, because of the backwardness of technology, the 5-year survival rate of patients was less than 20%. With the advancement of medical technology, not only can we save the limbs of patients, but also the survival rate of patients has been significantly improved. The commonly used treatment for cancer is radiotherapy, which is more painful for patients, and the probability of recurrence after treatment is greater, and the 5-year survival rate is also 60%~80%. From this point of view, osteosarcoma is not more terrible than cancer. Patients should set up confidence in treatment, actively cooperate with doctors, do not self-medicate, and if they feel unwell, they should receive regular treatment from doctors.
