Hi well come to HCM.
Since stage 4 with spread in other parts of body, only treatment left out is chemo thearpy. Radiation
to particular part will not help, and even surgery at so many
area is not possible. Best thing is chemo therapy with maximum symptomatic
treatment and comfort to him is more important for what ever life is left out. should
not hasitate to use even addictive drug if needed for pain. Thanks
