Shoalhaven Mayor Joanna Gash is recovering in hospital following breast cancer surgery yesterday.
Councillor Gash was diagnosed with cancer in late April.
She is in the Prince of Wales Private Hospital, Sydney where a lumpectomy was performed on Monday.
Biopsies on the tissue removed will be tested with results expected in the next eight days.
Cr Gash was determined to get back into her role as Mayor as soon as she can.
However if the tests show the cancer has spread, her full breast might have to be removed, which will delay her return.
She has reported she feels well following her surgery and thanked her well-wishers for their support.
