Hi everyone I would like some information on Histiocytic Sarcoma. My dad was very poorly with back/muscle pain for the last 5 months or so and it got so bad in February that he was sent to Hospital for scans where they found he had stage 4 HS. Its a huge shock as my my fought and beat stage 4 Ovarian Cancer last year. There is not much information, and all they can do is do radiation an chemo therepy which dad is not doing well on as its killing his red and white blood count and he has to get 3 pints of blood every 3wks. Any info to help us would be great.
