cancerous tumors的意思|示意

Dogs with long noses may develop cancerous nasal tumors from living with a smoker - and short-nosed breeds are more prone to lung cancer.

和一个老烟枪住一起，长鼻型狗狗会导致鼻肿瘤，短鼻型狗狗则多发生肺癌。

Recent research has shown that aberrant versions of this cluster are involved in preventing pre-cancerous cells from dying and allowing them to proliferate into tumors.

新近研究显示，这一簇miRNA的异常表达可防止癌变前细胞死亡，并令它们增殖成肿瘤。

Then they mapped out how these genes ultimately lead to cancerous tumors and checked whether the genes occurring in specific tissues used the same or different cancer pathways.

于是他们绘出了这些基因最终导致癌性肿瘤的路径，并且检查发生在特定组织的基因是否应用相同或不同的癌通路。

Fortunately, most of these tumors are not cancerous.

幸亏这些肿瘤多数不是癌症。

The growth of cancerous tumors is fueled, at least in part, by the buildup of free radicals-highly reactive oxygen-containing molecules.

自由基(极具化学反应性的含氧分子)的聚集，至少在某种程度上，使恶性肿瘤的生长如同加了燃料一般。

This suggests that a molecular "survival of the fittest" scenario plays out in every living creature as gene mutations strive for ultimate survival through cancerous tumors.

这表明在每种存活的生物中当基因突变凭借癌性肿瘤为了最终的存活，分子的“适者生存”故事结束了。
