cancer like aging seems to be an enormous ly resilient set of processes and you know biology and evolution have been pretty thirsty so the mechanisms as you know of many cancers are mechanisms that are used in early field development by the body so these are tools that our organism has for developing in the first place and unfortunately they run some risk of getting reactivated later in life and doing crazy stuff that's contrary to our interests and so this trade-off between the apparatus that we've been given to become healthy and mature and the processes that ultimately are our undoing seems quite difficult to overcome
