Dear friend, welcome and thanks for entrusting your query here at Healthcaremagic!
I am Dr. Prasad Akole (Critical Care Expert- http://bit.ly/Dr-Prasad-Akole) and am glad to address to your query here.
It seems to be a venous angioma
or an areterio-venous fistula.
It is an abnormal cluster of tortuous vessels (veins or artery
to vein connections).
If it is enlarging rapidly, operating on/biopsying a vascular malformation
is disastrous if it bleeds too much (which it does). Usually an expert in this job may prefer to inject the feeders with a glue or coil to occlude and reduce the vascularity and then operate in 2nd stage.
Uncommonly, it may a vascular tumour or cancer.
Did they say it is a tumour or growth?
It is likely to be a vascular malformation from your description.
Better to get an earliest appointment of the interventional vascular surgeon and be guided by his opinion.
I hope to have answered your query satisfactorily. I would be glad to answer any further queries. Take care and please keep me informed of your progress at http://bit.ly/Dr-Prasad-Akole
