The heightened accuracy allows for a more precise radiation dose and a more targeted area for treatment of the tumor.

而提高精确性之后就能使用更准确的放射剂量，并更好的对肿瘤进行定位。

Sometimes this is favorable, as these targets can also be involved in tumor development. In other cases, increasing the dose only leads to an increase in side effects.8, 9, 10.

有时候这是有益的，因为这些靶点同样参与肿瘤的进展。

The chemical keeps the cocktail intact until it binds to a cancer cell, delivering a potent dose of anti-tumor poison.

This allows doctors to boost the dose at the core of the tumor while giving lower doses at the edges, preserving healthy tissue.

The committee has concluded that there is no compelling evidence to indicate a dose threshold below which the risk of tumor induction is zero.
