Help!!

I am named Yolanda and I live in Spain, I was wanting to
make him a consultation: I have a sister of 45 years that
does seven years they extirpated the left- handed his mamma,
to the four years they reverted to finding him affected the
straight chest's ganglions, I try with chemotherapy ( this
time but lazy person ) and when he was seeming cured after 3
years he reverts to coming him out, they decide operating
and when they test out they unveil that they are not able to
because this one stuck to the thoracic wall, they drive to
do it but you try and they find a nodule in the lung and
other in the liver. My question is : That the fellow of
treatment can follow himself?Also I have heard about the
transplant of medulla ... And most of all want to knowing,
if we are talking about a fixed term of life in these cases
or on the contrary there is cure. Advancely THANKS and
forgive if I have made mistakes in the diagnosis's
transcription, no I have in my power no test
