The study was conducted by the University of Michigan Comprehensive Cancer Center - it's small but clearly shows that most women who are diagnosed with cancer in one breast have a very low risk of cancer re-occurring in the healthy breast.
It's not a decision E News host Giuliana Rancic made lightly.
"At the end, all it came down to was just choosing to live and not looking over my shoulder," Rancic said.
After consulting with family, she decided it was right for her. However, the new study from UM says the overwhelming majority of women who have both breasts, the chance of the cancer redeveloping is very low.
The suggested exception to this is women who have a history of two or more immediate family members with breast or ovarian cancer or women who have tested positive for the gene that causes breast cancer.
