对于癌症发生的原因,目前虽已有不少线索和重大研究成果,但还未完全弄清发病的根本病因。不过,许多研究证明,引起癌症的原因与化学的、物理的、生物的因素有关,而人们的饮食就是致癌的主要原因。因此,注意人们饮食卫生,是预防“癌从口入”的有力措施。概括起来,在饮食上要从以下6方面引起重视,才能预防癌症“病从口入”。 Although there are many clues and major research results for the cause of cancer, the underlying cause of the disease has not yet been fully understood. However, many studies have shown that the causes of cancer are related to chemical, physical, and biological factors, and that people’s diet is the main cause of cancer.

To sum up, it is necessary to pay attention to the following six aspects in the diet to prevent cancer from being “admitted from the mouth.”
