A member asked:

Do angiosarcomas of the breast grow quickly? why are there so many false negatives on biopsy?

A doctor has provided 1 answer

It is a bad Cancer!: Angiosarcoma of the breast is a well known entity, yet it is uncommon and difficult to diagnose because of the diffuse infilteration of the sarcoma into the normal tissues. Prognosis tends to be bad unless it is a small tumor and it is treated aggressively by a medical oncologist who is also a sarcoma expert(rare speciality).
