Rhabdomyosarcoma Adult

Hi, I am Justianus Rachmat from Indonesia. My father recently just had the PET SCAN and Biopsy and the result, he has a Rhabdomyosarcoma Tumor in his upper back tight. The tumor has spread to his lung and until today, he has no pain or sickness felling. I desperately need some information regarding the outcome of survival. Anyone had the same case like my father, please share with me. The diagnose from Dr Orthopedic is in stadium 4.

Thank you,
