What are the chances of HER2-positive breast cancer recurring?

HER2-positive breast cancer does have a higher risk of recurrence compared to some other types, but treatment advances have significantly improved outcomes.

With modern targeted therapies, about 25 percent of people with HER2-positive breast cancer experience a recurrence within 10 years. This is a notable improvement from the past, when recurrence rates ranged from 30 to 50 percent within 10 years before targeted therapies became available.

HER2-positive breast cancer tends to recur earlier than other types, with the highest risk occurring around 20 months after diagnosis or completing treatment. Most recurrences happen within the first five years.

Your individual risk can vary based on several factors:
- Tumor size and stage at diagnosis
- Whether cancer cells remained after initial treatment
- Lymph node involvement
- Age at diagnosis (higher risk if 50 or younger)
- Hormone receptor status
- Body mass index

The good news is that targeted drugs like trastuzumab (Herceptin) have dramatically improved outcomes for HER2-positive breast cancer. Regular follow-ups and self-exams can help catch any recurrence early when it's most treatable.
