Multiple primary cancer and cancer, multiple repeat cancer, the body simultaneously or successively occurred two or more than two other unrelated cancer (or the same patient at the same time or has occurred two or more than two kinds of different kinds of cancer). Diagnostic criteria of multiple primary carcinoma: multiple primary malignant tumors (multiple primary malignant neoplasms) generally follow the diagnostic standard of Warren, namely each tumor histologically must be malignant; each tumor pathological morphology of each other; each tumor occurred in different parts or organs shall be excluded; metastasis or recurrence of cancer. The different parts of the same organs occurred more than two primary malignant tumors known as multiple primary malignant tumors, and in more than two organogenesis of primary malignant tumor called cancer. But most of the literatures that repeated carcinoma and multiple primary malignant tumors with multiple primary malignant disease. The tumor can be respectively from the same organ, paired organs, the same system and different system. Therefore, those who meet the following criteria, can be diagnosed as multiple primary cancer. Each tumor was malignant. The histological images of each tumor were observed by microscope. Treatment and prognosis of multiple primary malignant tumors and metastatic tumors. The former has a considerable number of patients with the hope of cure, and the latter is no cure for the hope of advanced patients. Therefore, if the patient was found to have a tumor, do not believe that recurrence or metastasis, if it is more than the primary cancer, then there is hope of treatment.
