People generally think that teenagers are not related to cancer, but orthopedic experts have proved through clinical research that primary osteosarcoma, the most dangerous type of bone cancer, usually affects young people. Therefore, we remind patients that adolescents with unexplained bone pain should be aware of bone cancer. Bone cancer usually occurs in adolescents. Because of the rapid growth of bones in this period, the pain caused by bone cancer can be easily mistaken as normal physiological phenomenon – growing pain, or thought to be general arthritis, sprain or periostitis, and the best time for treatment is missed. Some cancers preferably occur in lower age groups, for example, leukemia mortality rate is high in young children, while bone cancer is high in teenagers. It has been recorded in the literature that bone tumors rank second in childhood mortality, among which osteosarcoma is the most common primary malignant bone tumor, mostly seen in adolescents aged 10 to 25 years. It starts rapidly and metastasizes rapidly within a short period of time. Adolescents with unexplained bone pain should be alerted to bone cancer Although the exact causative factors of bone cancer are still inconclusive, it is generally believed to be related to genetic changes. The annual incidence of osteosarcoma is 1 in 1 million to 3 in 1 million, with about 3/4 occurring in the knee joint. It has been scientifically proven that patients who have had retinoblastoma in the eye as a child have a fairly high chance of developing bone cancer later in life. Clinical manifestations of osteosarcoma include relatively rapid growth of the mass, pain, increased local skin temperature, functional impairment, and pathological fractures. This is because the tumor cells multiply particularly rapidly in the bone marrow cavity, causing abnormally high pressure in the cavity and thus causing patients to feel severe pain. Although the incidence of osteosarcoma is not high, it is quite dangerous, and the cancer cells will develop lung metastasis within six months to a year, thus causing the patient’s death. So how to prevent bone cancer? In life, many people are not very clear about what factors will cause the risk of bone cancer development, and in this case, effective defense against bone cancer attack is an impossible thing. Therefore, in order to avoid the frequent occurrence of bone cancer, we need to pay attention to understanding which adverse factors are related to the occurrence of bone cancer disease in daily life so that we can do effective prevention work. 1.Radioactive elements. This factor is closely related to the development of bone cancer and needs to be strengthened in daily defense. Radiation such as X-rays used in the treatment of other diseases can also damage bones and lay the hidden danger of bone cancer. In addition, radium, strontium and other radioactive substances may increase the risk of bone cancer, which is a cause of bone cancer. 2. In life, we will inevitably be attacked by some trauma, and if the bones are injured, then the risk of bone cancer will be formed. Accidental injury is another cause of bone cancer. In our daily life and work and study, it is inevitable to cause some accidental injuries, which can damage bones and increase the risk of bone cancer. 3. Genetic factors also play a great role in triggering the development of bone cancer. However, this is not absolute. Generally speaking, having bone cancer patients in the family does not necessarily lead to bone cancer in the next generation, but relatively speaking, the risk will be higher. This cause of bone cancer is more common. With the improvement of medical technology, there is a significant breakthrough in the treatment of bone cancer in China. 90% of patients can now undergo limb preservation surgery, and the 5-year survival rate of patients has increased from 5%-20% more than 20 years ago to 80% at present. Like other cancers, the sooner you seek medical treatment for bone cancer, the better. If adolescents experience swelling, pain, high local skin temperature and limited joint movement, they should not take it lightly and should seek medical treatment as soon as possible. Warm tip: After the diagnosis of bone cancer, it is important to carry out surgery in time, and not to cast doctors or use prescriptions indiscriminately, if the best treatment time is missed, then only amputation can be performed.
