The bacon diet reduced the number of precancerous lesions in rats injected with the azoxymethane.

在注射了氮氧甲烷的老鼠中，食用培根减少了癌前病变的数量。

An area of frictional keratosis is not a precancerous lesion and usually fades away once the irritation stops.

摩擦性角化不属于癌前病变，一般当刺激因素去除后，它会自行消退。

But if you gave these calcium deficient rats some calcium, they had no such increase in precancerous lesions.

但是如果你给这些缺钙的老鼠一些钙，它们并不会发生癌前病变。

Treatment of precancerous lesions begins with active surveillance, removing any diseased tissue, and stopping any causative agents, like smoking and alcohol abuse.

癌前病变的治疗要从积极监测开始，任何病变组织都要被去除，还要停止接触一切致癌物，如戒烟戒酒。

Well, one of the initial studies looking at that idea that heme iron causes cancer, fed calcium deficient rats a heme iron rich diet and found that indeed, these rats developed precancerous lesions in their colon.

在一项关于血红素铁能致癌的初步研究中，钙缺乏的老鼠被喂食富含血红素铁的食物，该研究发现，这些老鼠的结肠发生了癌前病变。

If we had that map of the molecular changes of a pre-cancer to a cancer, we could develop ways of finding people that are harboring these precancerous lesions, and then blocking them from ever getting an invasive disease.

如果我们有从癌前进展到癌症的分子变化图谱，我们就可以开发出能找出携带这些癌前病变分子患者的方法，然后阻止他们患上入侵式疾病。

If we had that map of the molecular changes of a pre-cancer to a cancer, we could develop ways of finding people that are harboring these precancerous lesions, and then blocking them from ever getting an invasive disease.
