The early symptoms of osteosarcoma include pain, which initially is intermittent. As the condition progresses, this intermittent pain gradually becomes constant, and the intensity of the pain is parallel to the severity of the osteosarcoma, meaning the more severe the osteosarcoma, the more intense the pain. Additionally, you can also feel a lump forming on the affected limb, and this lump is clearly tender to touch. The third symptom is the occurrence of a limp. This limp is due to pain, which prevents the patient from bearing weight and walking for extended periods. Lastly, all osteosarcomas present symptoms such as anemia, pathologic fractures, and a low-grade fever.

Can osteosarcoma be cured?

Osteosarcoma is a malignant tumor of the bone, commonly occurring in adolescents and young adults, primarily near the proximal end of the tibia, the distal ancient end, or near the proximal end of the humerus, most frequently seen at the end of the bone shaft. In the early stages, there are no symptoms, and once detected, it is usually in the middle to late stages. An X-ray examination can be used for diagnosis, often showing a Codman's triangle or a sunburst pattern. Osteosarcoma generally needs early detection and treatment. If a primary lesion is present, surgical treatment can be pursued, including procedures such as resection with inactivation and reimplantation or limb-sparing surgery with a prosthesis. Another option is amputation, followed by extensive chemotherapy. The likelihood of osteosarcoma spreading to the lungs is very high. In recent years, with early diagnostic physical examinations and the rapid development of chemotherapy, the five-year survival rate for osteosarcoma can reach 50%.

What does osteosarcoma feel like to the touch?

Osteosarcoma is a malignant tumor that consumes bone and typically shows no symptoms in its early stages. By the time symptoms are recognized, it is usually in the mid to late stages. There might be localized masses; upon discovery of such masses, a visit to the hospital for diagnostic imaging is needed. Radiological examinations reveal characteristic signs such as sunburst appearance and Codman's triangle on X-rays. Further investigation with MRI or CT scans is necessary, followed by a biopsy for confirmation. During physical examination for this type of osteosarcoma, a localized mass may be found typically around the proximal tibia or distal femur, mainly around the metaphyseal ends. The mass may be accompanied by localized heat and pain, with nocturnal pain being more pronounced. Additionally, patients might show varying degrees of weight loss. Generally, osteosarcoma can be diagnosed through physical examination and radiological findings, followed by a confirmatory biopsy. Early stages require surgical intervention. Furthermore, osteosarcomas have a high rate of early pulmonary metastasis. Using extensive chemotherapy can improve patient survival time. With rapid advancements in chemotherapy, the five-year survival rate can reach about 50%.

Osteosarcoma Causes

Osteosarcoma is the most common malignant tumor of the bone and typically presents without symptoms in its early stages. The cause of osteosarcoma is unknown, and it often goes undetected until it has reached a moderate or advanced stage. It commonly develops at the distal end of the femur near the knee joint, at the proximal end of the tibia, or at the proximal end of the humerus, primarily at the end of the growth plate. The pain associated with osteosarcoma is usually persistent, especially severe at night, and can lead to symptoms such as anemia or general wasting. The tumor's surface may be warm to the touch, with prominent veins visible, and radiographic imaging might show a Codman's triangle, indicative of sunlight-like radiation patterns, as well as bone destruction and clear periosteal reaction. Surgical treatment is typically pursued, with amputation being the most common procedure, though limb-sparing surgeries are possible if the tumor is detected early enough. Some cases metastasize, most commonly to the lungs, requiring continued high-dose chemotherapy post-surgery to prolong survival. Generally, the five-year survival rate for osteosarcoma can exceed 50% with early diagnosis and treatment. The chances of survival heavily depend on the individual’s constitution, the timing of tumor detection, and the surgical intervention. The exact causes of osteosarcoma are unclear, and the potential for metastasis complicates treatment. Therefore, early surgical intervention is crucial for improving survival rates and enabling patients to maintain a normal life and work activities.

Why is there a cough in osteosarcoma?

Osteosarcoma ranks second in the incidence of malignant tumors in the whole body's bones; its incidence is relatively high. It generally occurs in the long tubular bones, shafts, or epiphyseal areas of the limbs. Since the most common organ metastasis of osteosarcoma is to the lungs, if a patient with osteosarcoma develops a cough, it should be taken seriously, and it's recommended that the patient undergo a targeted examination such as a chest X-ray or a CT scan of the lungs to check for lung metastasis and any lesions on the lungs. However, there is no need to panic prematurely, as osteosarcoma patients might cough due to upper respiratory infections or lung infections, which doesn't necessarily indicate lung metastasis. Therefore, once a patient with osteosarcoma develops a cough, a targeted examination should suffice.
