My Ellen underwent a breast lumpectomy in NY several months before we moved to TV. Her radiation treatment took place here in early '13. Dr Bundz, who came highly recommended, removed the port she had had installed back in NY for chemo. We were impressed (and did our own homework) and would request his services without hesitation for surgical matters.
Ellen has been cancer free for almost two years. As Gracie said, your future does look bright if you have been directed to a lumpectomy.
You will be specifically in my evening prayers. May God's grace shower you and strengthen you.
