自噬（autophagy）被很多人看做健康飲食、控製體重的好措施。但偶爾發現竟然有自噬不利於癌症治療的敘述，看這裏：

"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."

 

 

偶爾看到上述說法，這個說法正確嗎？
