What are the chances of brain metastasis spreading more if the actual lung cancer is regressing?
Hi everyone. Want to find out, what are the chances of brain metastasis spreading more if the actual lung cancer is regressing? My dad’s last PET showed that his cancer is regressing but when he did an MRI on his brain, doctors said that they see a new metastasis. Doctors asked to redo the MRI since looks like my dad was moving his head during the last MRI and they could not see the real picture. I hope that the picture will be better after the second MRI. I thought the chemo and immunotherapy that he is doing is helping on brain metastasis too but after my research looks like not much. Thanks
