Fig. 4: Annual risks of contralateral breast cancer, by ER status (invasive breast cancer patients only).
From: The risk of contralateral breast cancer: a SEER-based analysis
Annual rates of contralateral breast cancer since diagnosis were calculated by ER status among women with invasive breast cancer. Women with ER-positive breast cancer had a lower annual rate of contralateral breast cancer in the first 10 years of follow-up, compared to women with ER-negative breast cancer. Beyond 10 years from diagnosis, the rate of contralateral breast cancer was similar in both groups.
