My son(53) had oesophagus tumour removed in December slowly beginning to eat more then scar tissue closed the oesophagus, he was given 1 session of dilation He was given the chance to have immunotherapy and had first dose but this has resulted in inflammation around his heart and partial loss of vision and back into hospital. Further scan have shown some cancer in his liver , he has now been offered the option to have a stent fitted to improve what could be better quality of what life he has left.
Is a stent permanent? Would more dilation allow him to eat more normally. He's been told that the liver cancer is inoperable. Just need advice please
