Jaqueline Lees, a cancer researcher, is in an online video on cancer. It’s quite good, and she is better than most scientists when it comes to talking to the public about technical issues. She explains the development of tumors through several stages, which can potentially take years. This makes sense to anyone who follows mesothelioma and knows of its long latency period.
Cancer is essentially a genetic disease, she says, and she talks about the two types of geners that can allow cancers to form: ongogenes and tumor suppressor genes.
