长期暴露于手机辐射已知会增加某些癌症的风险，如胶质瘤 – 一种常见的脑肿瘤。现在一项新研究表明，暴露于手机辐射也会加重癌症患者的预后。
该研究考察了手机辐射对两种人头颈癌细胞系FADU和SCC25的影响。具体而言，研究人员想知道辐射如何影响头颈癌细胞的血管生成，细胞侵袭和集落形成。他们还想调查手机对E-cadherin和Erk1 / Erk2基因调控的影响。
更重要的是，研究人员发现手机辐射可以在我们的实验模型中激活Erk1 / Erk2。 Erk1和Erk2参与肿瘤发展。
该研究得出结论：“我们的研究表明，手机射频可通过Erk1 / Erk2激活刺激血管生成和细胞侵袭来增强头颈癌。”
Cell phone radiation can make cancer more aggressive
Long term exposure to cell phone radiation is known to increase risk of certain cancers like glioma – a common brain tumor. Now a new study indicates that exposure to cell phone radiation can also worsen prognosis of cancer patient.
The study examines the effect of cell phone radiation on two human head and neck cancer cell lines, FADU and SCC25. Specifically, researchers wanted to know how the radiation affects angiogenesis, cell invasion and colony formation of head and neck cancer cells.
They also wanted to investigate the impact of the cell phone on the regulation of E‐cadherin and Erk1/Erk2 genes.
They found cell phone radiation promotes angiogenesis and enhances cell invasion and colony formation of human head and neck cancer cells which is accompanied by a down-regulation of E-cadherin expression.
More significantly, the researchers found the cell phone radiation can activate Erk1/Erk2 in our experimental models. Erk1 and Erk2 are involved in tumor development.
The study concluded that “Our investigation reveals that cell‐phone radiofrequency could enhance head and neck cancer by stimulating angiogenesis and cell invasion via Erk1/Erk2 activation.”
It is not a surprise that cell phone radiation can make cancer cells more aggressive. This is like x-ray which can promote cancer development. X-ray can also make cancer cells more aggressive.
For that reason, cancer cells that are treated with radiotherapy often become resistant to radiation treatment. These cells become stem like cancer cells meaning that they are harder to kill and these cancer cells can come back to kill cancer patients.
This is one of the reasons why cancer patients who are initially diagnosed with early staged cancer end up with developing terminal cancer and dying from the terminal cancer.
Cell phone radiation is expected to have a similar impact to x-ray.
