Sandra Lee back at work after cancer treatment

Sandra Lee has headed back to work after her successful treatment for cancer.

The TV chef and girlfriend of New York Gov. Andrew Cuomo posted a picture on Instagram on her first day back filming.

“First day back on set — am shooting with @bobbyflay. Nice to be with my brother. #foodnetwork #bobbyflay.”

Lee had a double mastectomy last May and then underwent surgery to treat an infection. She announced she was cancer-free in September.
