I had lung cancer and lobe was removed 2 months ago. I just had a mri that shows i have 5 small c cels in the brain. Doctor recommends whole brain surgery since there are 5 tumors, but i know there are other options but am confused which way to go. the tumors are small.I have heard of gamma knife but dont now if its better than whole brain treatment. The thought of permanent hair loss is also devestating. Can anyone help me with answers to whole head radiation? what are advantages and dis advantages. I am very scard. I dont know what options are best for me. Any help will be very appreciated.
