This problem itself is put in wrong idea and acknowledge, why is tumor treated bad? The person that quiz maintains tumor to treat in the heart above all bad, just be next on this foundation " why " treat bad.
Come above all kink mistake is cognitive: Tumor is treated bad. Is tumor treated really? May not, must treat specific condition. All do not divide particular case try to attend to big and small matters all at once be destined is not rigorous. Why is tumor treated bad, this problem is just like is to ask " the factitious what that Xx saves is very bad " same absurdity, the person that which province there is is bad? The bad one part that also is this province only just, since the person of this province is not bad, he Laiwei the problem with bad what.
Return tumor this problem, tumor also has a lot of different cases, have benign tumor and malignant tumor, it is malignant tumor likewise, have different in installment (inchoate, metaphase, terminal, this is the view of common people, use well and truly on medicine 1, 2, 3, 4 period) , have different cancer kind, even if is same in installment, same cancer kind, different patient also is different, how can treat as the same, how can one stick all tumour bad to treat? Be no good of course!
Benign tumor majority is good treat, operation excision can cure, you cannot say benign tumor is bad to treat. But even if is benign tumor, when you see me say, also be to have " most " , and did not change absolutely, because have a few,benign tumor also is bad to treat.
Malignant tumor is inchoate and most can cure, can say very good treat. But same, what say here also is " most " , did not change absolutely, not be all and inchoate cancer can cure, some also is treated bad, some is treated hard also.
Malignant tumor is terminal and most bad to treat, majority is treated bad, but minority cures likely still. Terminal and malignant tumor is the difficulty that treats at present really, because this is most terminal cancer is treated really bad, bad to treat, but also cannot change absolutely likewise, cannot say all cancer are terminal treat bad. I think, if quiz person set definitive: Is most and malignant tumor terminal why bad to treat? So this problem just calculates carry thoroughly, because majority is malign tumor is terminal and bad to treat, this is a fact, did not contend for doubt, come so, just be to talk next " why " , bad to treat, why bad to treat?
Benign tumor and inchoate cancer basically rely on an operation to excise, or effect a radical cure the gender puts cure; The terminal cancer that minority can cure, it is what sensitive to changing cure height malignant tumor. Even if was transferred, diffused, also can pass change cure (should add target to wait to medicaments sometimes) will exterminate. And most and terminal cancer, although some is sensitive to changing cure, but still do not talk to go up height is sensitive, some is not sensitive, below this kind of circumstance, through changing cure also can be finite control only, also do not make even finite control even.
Why is most and terminal cancer treated so hard? Said in front, change cure to be opposite this part cancer only the part is sensitive, some is far from sensitive, and even if is temporarily sensitive, also can be able to bear or endure sooner or later medicine thereby invalidation, have to seek new remedy, but even if was to have new pharmaceuticals, be able to bear or endure medicine also is sooner or later, this is difficulty and crucial place.
Actually, the most primary reason is, the reason that cancer happening grows has not been cleared up completely, the mechanism that cancer happening develops is complex, we treat the medicaments of cancer or method now, just solved among them part problem, do not say to change cure medicaments, take the hottest now target to medicaments or immune medicaments for, target to medicaments it is to be aimed at cancer to grow a certain access of development undertakes block is broken, but also be block is broken only a certain or certain route, snap all route without block, and itself cancer grows the access of development was not cleared up completely. Is immunity treated? Just solved certain or certain respect as much at present, tumor immunity is very complex likewise, instantly is the for instance most popular refuse treatment of PD-1 antibody immunity, those who be aimed at is mere also it is a dinky respect in immune mechanism, this is to be over apparently insufficient, want pure rely on this to cure all cancer, it is impossible at all. Want thorough and lucid complete and witting cancer to grow only all mechanisms of development, ability is possible true " capture " cancer, but eye comes round to say, it seems that unlikely, future has a possibility, perhaps.
