Hi everyone, long time listener, first time caller. I was diagnosed in 2018 with ER+/PR+ IDC. Went through lumpectomy and radiation, then started on Tamoxifen + Lupron injections. After a year, I was switched to AI + Lupron and have been on that "gold standard" regimen for two years. Imagine my shock when I developed a tumor in the opposite breast (thankfully small and DCIS) that is strongly ER+.

Freaking out a little as to how this is happening just 3 years later and wondering what the future holds (I'm 41). Does anyone have access to data on how common a second ER+ tumor is while on hormonal treatment? My estrogen levels had been checked just a few months prior to diagnosis and confirmed to be in the post-menopausal range. I realize nothing is bulletproof but this has me really scared.

Has anyone else been through this? How do you deal with the anxiety that this is going to happen over and over again despite being on the "gold standard" for treatment?

minisub,

The unfortunate reality of bc is that there is no guarantee, despite treatment, that you will not have a recurrence or even a new primary. There’s also no way to predict who will or won’t have to deal with bc again. Focus on what you know now and don’t borrow trouble from the future! Take care.

Recurrences are unfortunately common. And they usually occur within the first few years after diagnosis and treatment, so finding another one at three years isn't unusual. Estrogen blockers don't block 100% of the estrogen your body is producing, and even if they did, cancer finds a way around it. That's why so many cancer treatments eventually stop working. You're super lucky it's just DCIS! But it's definitely scary to have another trip around the cancer ride. :(
