My dads ONC has told my mom that from my dads original PET scan that he thinks that my dads lc may also be on his rig cage. Is this a common thing. He has only had the radiation on his lung and also went through 8 rounds of chemo. Has anyone had mets to the ribs and if so what is the outcome. He goes for his 2nd PET scan on July 7th so we will know more but I was just wondering as usual about this horrific disease.
