A metastasis may be the first sign of a malignant tumor. Most commonly this is a pathologically enlarged lymph node, but other symptoms caused by metastases such as pathologic bone fractures may also produce the first symptom of the disease. When searching for the primary tumor, the site of the metastasis and the patient's clinical data must be taken into consideration. Along with possible additional investigations, imaging studies and a biopsy taken from the metastasis lead to diagnosis in 90% of cases. The origin of metastasized tumors remains unraveled in approximately 3 to 5% of cases.
转移可能是恶性肿瘤的首个迹象。最常见的是病理性肿大的淋巴结，但转移引起的其他症状，如病理性骨折，也可能成为该疾病的首发症状。在寻找原发肿瘤时，必须考虑转移部位和患者的临床资料。除了可能的其他检查外，影像学研究和对转移灶进行活检可使90%的病例得以确诊。在大约3%至5%的病例中，转移瘤的起源仍不清楚。
