Some days after treating the tumor, I found that the tumor is very similar to an animal —- mouse . This is my metaphor. The similarities between them are: 1, habits _ to waste, waste for their own responsibility; 2, growth and reproduction _ not to waste a second of time, to reproduce at the best speed; 3, evolutionary ability _ to Darwin has done a very in-depth study, there is a strong ability to adapt to changes in the living environment; 4, human research _ to destroy them, human research, as far as we can, the “weapons” can be used all the use 5, the final result _ so far, mankind can only say that “can control”, not to “eradicate”. Saying this may cause some people to curse; may also affect the confidence of some patients for the treatment of the disease. But my purpose is to cause people to choose the treatment method, do not want to use the “extermination method” to treat, should think about their “natural enemy” there are inappropriate, please criticize the correction!
