肿瘤(tumour)是指机体在各种致瘤因子作用下,局部组织细胞增生所形成的新生物。随着疾病谱的改变,肿瘤对人类的威胁日益突出,肿瘤一旦形成,将不受生理调节,同时可破坏正常组织和器官,且易转移,切除后易复发,治疗困难。因此,早期发现并及时治疗对肿瘤患者的预后和术后生存率具有重要意义。临床上,肿瘤的诊断以CT、MRI
Tumor is a new organism formed by the proliferation of local tissue cells under the action of various tumorigenic factors. With the change of the spectrum of diseases, the threat of tumors to humans has become increasingly prominent. Once a tumor is formed, it will not be subject to physiological regulation. It can also damage normal tissues and organs, and is easy to metastasize. Recurrence after resection is easy and the treatment is difficult. Therefore, early detection and timely treatment are of great significance for the prognosis of patients with cancer and postoperative survival. Clinically, the diagnosis of tumors is CT, MRI
