Thats an understandably frightening thought, even if you know there are screening tests that may find cancer even before you have symptoms. However, early checkups can help doctors detect any cancers early and provide prompt treatment. How are genetic conditions treated or managed? Recent studies suggest that folliculin accomplishes this function through its involvement with cellular metabolism, possibly through modulation of the mTOR (mammalian target of rapamycin) pathway and/or oxidative phosphorylation in mitochondria.
