Could my cancer still come back?
You finish treatment. You count the years. You start to breathe again. And then, out of nowhere, the cancer shows up again. Not in your breast. Maybe not even in your chest area. But in your bones, your liver, your lungs. It’s called late recurrence, and for many people with hormone receptor–positive breast cancer, it’s not just a possibility, it’s a very real risk that lingers long after the five-year survival milestone everyone celebrates.
For patients with ER-positive, HER2-negative breast cancer, studies show that recurrence risk doesn’t vanish at year five. In fact, for some, it stretches well into year 10, 15, or even 20 and beyond.
A landmark study in The New England Journal of Medicine found that women with early-stage, hormone receptor–positive breast cancer had recurrence rates of 10% to over 40%, depending on tumor size and lymph node involvement, even 20 years after completing initial treatment. Other studies confirm the pattern. This NIH analysis outlines several risk factors for late recurrence, including larger tumor size, higher grade, and lymph node involvement. These aren’t just stats, they’re facts to encourage you to stay vigilant.
Survivorship isn’t a finish line like most people assume. In reality, it’s a new phase of care that deserves just as much attention as treatment. If you’re still on endocrine therapy (like tamoxifen or aromatase inhibitors), you may already be reducing your risk. Extending endocrine therapy to 10 years has shown real benefits for some women. Yes, the side effects can be tough but so is a distant recurrence.
And if you’re not on hormonal therapy anymore? This is the time to ask your doctor:
- “Am I still at risk for late recurrence?”
- “Should we revisit long-term surveillance strategies?”
- “What signs or symptoms should I never ignore?”
Thanks to advances in technology, we may soon be able to detect recurrence before it causes symptoms. One promising approach: circulating tumor DNA (ctDNA) and minimal residual disease (MRD) testing.
- A 2024 study showed that a blood-only ctDNA test could detect early recurrence in breast cancer patients sometimes months before traditional scans or symptoms.
- Another study shared at the 2024 ASCO Annual Meeting showed that a highly sensitive blood test, designed using each patient’s specific tumor DNA, could detect tiny traces of cancer (known as minimal residual disease (MRD) ) in early-stage breast cancer patients. This means doctors may be able to spot signs of cancer coming back before symptoms appear or traditional scans pick it up, giving patients a chance to act sooner.
These tests aren’t yet standard of care, but they’re worth asking about, especially if you have ongoing symptoms or a high-risk history.
The threat of late recurrence isn’t just medical. It’s emotional too. The fear can linger long after treatment ends, and pretending it’s not there only adds to the weight. This isn’t about living in fear, it’s about staying aware. You’ve come too far to go quiet now. Trust your instincts. Ask the hard questions. Advocate for the scans or bloodwork if something feels off. And just as importantly, take care of your mental health because peace of mind and finding joy after cancer matters.
