    It looks like scientists have observed mitochondrial DNA (mDNA) transfers from healthy to tumour cells in animals for the first time. I'm not sure if the spread of the tumour means that the mDNA spread as well to healthy cells, or if the spread of tumours is due to nuclear DNA or something else. It sounds like removal of the mDNA from tumour cells can suppress them, but once mDNA from a healthy cell is transferred to the tumour cell it powers back up.

    What do you guys think? I have next to no idea what I'm talking about when it comes to this so please let me know if I made any mistakes or if you can provide better context.
