1. Bone tumors can be either benign or malignant and may originate from the bone itself or be metastatic from other parts of the body. Benign bone tumors, while not cancerous, can still cause problems if they grow too large or in a location that affects function or health. Malignant bone tumors can invade surrounding tissues and spread to other parts of the body through the blood or lymph system, which is known as metastasis.
骨肿瘤可以是良性或恶性,可能起源于骨骼本身或来自身体其他部位的转移。良性骨肿瘤虽然不是癌症,但如果它们长得过大或在影响功能或健康的位置生长,仍然会导致问题。恶性骨肿瘤可以侵入周围组织,并通过血液或淋巴系统扩散到身体其他部位,这被称为转移。
2. Symptoms of bone tumors may include bone pain, swelling, and an increased risk of fractures. Pain may be intermittent at first and then become constant, often mistaken for growing pains in children. As the tumor grows, it may cause a noticeable swelling over the bone and lead to pathologic fractures, which are fractures that occur due to the weakened bone structure from the tumor.
骨肿瘤的症状可能包括骨痛、肿胀和骨折风险增加。疼痛起初可能是间歇性的,然后变成持续性的,常被误认为是儿童的生长痛。随着肿瘤的生长,它可能导致骨头上方出现明显的肿胀,并导致病理性骨折,这是由于肿瘤导致的骨骼结构变弱而发生的骨折。
3. Diagnosis of bone tumors typically requires imaging studies such as X-rays, CT scans, or MRI, and often a biopsy is necessary to confirm the diagnosis. During a biopsy, a small sample of the tumor is removed and examined under a microscope to determine the type of cells present and whether the tumor is cancerous.
骨肿瘤的诊断通常需要影像学检查,如X光、CT扫描或MRI,通常还需要进行活检来确认诊断。在活检过程中,会取下一小块肿瘤样本,在显微镜下检查以确定存在的细胞类型以及肿瘤是否为癌症。
4. Treatment for bone tumors depends on the type, location, and stage of the tumor. Treatment options may include surgery to remove the tumor, radiation therapy to kill cancer cells, and chemotherapy to treat cancer that has spread or is likely to spread.
骨肿瘤的治疗取决于肿瘤的类型、位置和阶段。治疗选项可能包括手术切除肿瘤、放射疗法杀死癌细胞,以及化疗治疗已经扩散或可能扩散的癌症。
