自噬（autophagy）被很多人看做健康饮食、控制体重的好措施。但偶尔发现竟然有自噬不利于癌症治疗的叙述，看这里：

"Once cancer has formed, autophagy may protect the cancer cells by providing extra nutrients to them or by keeping anticancer drugs or other substances from destroying them. Autophagy may also affect the body’s immune response against viruses, bacteria, and cancer cells."

 

 

偶尔看到上述说法，这个说法正确吗？
