I had Angiosarcoma on my upper chest, near collar bone, several years ago. No radiation or any kind of chemo, just surgery. I have had numerous cancers and a wide variety of type of cancers.
(Bad genes!) I never have had anything but surgery for all my cancers.
So far, it has not shown up again, but I am plagued by numerous skin cancers and another Melanoma. I am so sorry you are going thru such trauma, especially on your face, that's really tough. (My nose is starting to look like a boxer's!)
Stay tough.
