- 在瘤学瘤学.
- 神经病理学神经病理学
- 辐射瘤学 辐射瘤学
背景情况:
- 周围神经膜瘤 (PNSTs) 通常是良性神经新生瘤.
- 常见的类型包括神经纤维瘤和神经纤维瘤,通常是零星的,但与神经纤维瘤等遗传综合征有关.
- 辐射暴露是这些瘤及其恶性变体的偶尔风险因素.
研究的目的:

02:21Cancers Originate from Somatic Mutations in a Single Cell
Cancer arises from mutations in the critical genes that allow healthy cells to escape cell cycle regulation and acquire the ability to proliferate indefinitely. Though originating from a single mutation event in one of the originator cells, cancer progresses when the mutant cell lines continue to gain more and more mutations, and finally, become malignant. For example, chronic myelogenous leukemia (CML) develops initially as a non-lethal increase in white blood cells, which progressively...
