And in controlled lab experiments there's a direct link between increased artificial light at night and a rate of tumor growth.

在受控实验室实验中，夜间人造光的增加与肿瘤生长速度之间存在直接联系。

And this is due to mutations in the TSC1 or TSC2 tumor suppressor genes, genes that usually suppress tumor growth, therefore a mutation leads to myocyte overgrowth.

由于TSC1和TSC2抑癌基因的突变，这些基因通常抑制肿瘤生长，因此此类基因突变可导致肌细胞过度生长。

Malignant tumor cells can get into nearby blood or lymph vessels, and travel from the primary site to establish a secondary site of tumor growth somewhere else in the body - and that's called metastasis.

恶性肿瘤细胞可以进入邻近的血管和淋巴管，从原发病灶到达身体的其它地方，形成继发病灶，称之为转移。

My doctors explained to me that while chemo and radiation would reduce the likelihood of recurrence, every three months for the rest of my life, I would need to return to the hospital to check for new tumor growth.

我的医生向我解释说， 虽然化疗和放疗会降低复发的可能性， 但在我的余生中，每三个月，我就需要回到医院检查是否有新的肿瘤生长。
