My father was recently diagnosed with an angiosarcoma on his right temple. is it better to surgically remove or to take the chemo radiation approach?

Angiosarcoma : The question you ask is not one that can be easily answered in this venue. Many things are considered before making a recommendation on the best option for treatment of a disease, in this case a malignancy. Location and extent of malignancy (stage), patient age, associated medical problems, among others. Consider meeting with a specialist that has expertise in angiosarcoma to review your situation.
