Hi,
My mom just had a dissection in November and is currently having radiation and chemo because the cells surrounding the lymph node tumors were positive for cancer.
Her treatment is at U of C in Chicago. Their protocol is radiation/chemo together as this is a good outcome of treatment.
I would ask which section of the neck his lymph node tumor remains in and if if has anything to do with nerve damage as to why they don't remove it all. The tumor that remains may be compromising something major, such as the juggular, etc. and radiation & chemo may be better to treat it if surgical removal is dangerous.
That is a very vauge answer and I would want more explanation. If this is not the treatment, than what is?
Best to you and family, hope this helps.
