提起癌肿,不少人“谈虎色变”。人类机体是否对癌肿无能为力,毫无抵抗呢?不是的。尽管癌肿现已上升为疾病引起死亡的首位,但发病率毕竟还是较低的,即使在“高癌家族”,患病的也是小数。机体与癌肿进行的斗争,多是通过免疫系统进行的。当哺乳类动物各种体细胞因种种原因突变为恶性肿瘤细胞时,就会及时地被免疫活性细胞识别为“异己”细胞而遭到排斥。 Raised cancer, many people “discussed.” Does the human body have nothing to do with cancer? Does it have no resistance? Although cancer has now risen to the top of the disease-causing death rate, the incidence is still low. Even in the “high-cancer family”, the number of people who suffer from the disease is also small. The fight against cancer is mostly carried out by the immune system. When mammalian cells are mutated into malignant tumor cells for various reasons, they are promptly recognized as “different” cells and are rejected.
