Sarcoma is neither a polyp nor a cancer, but just like cancer, the earlier it is found, the better the treatment effect, but if cancer is found in the metastatic stage, the chances of patients' recovery will be significantly reduced. Sarcoma is a kind of cancer found in connective tissue cells. Because these cells can survive in bone cells, cartilage, blood vessels and stem cells, sarcoma is divided into many types. But the following two types are the main types, namely osteosarcoma and soft tissue sarcoma. An oncologist at Kang Min International Hospital in Thailand pointed out: "Surgery is almost the first choice to treat sarcoma. However, surgery alone is not enough because sarcoma can spread rapidly. This is why chemotherapy and/or radiotherapy should be performed at the same time. However, instead of killing cells indiscriminately like traditional chemotherapy, we can now create targeted therapies or drugs for specific cancer cells. Because the symptoms of sarcoma may not be easy to find, patients are advised to constantly monitor and observe their own bodies. If there is any abnormality, please make an appointment with a doctor so as to get an accurate diagnosis and timely and effective treatment.
