I had a lumpectomy and radiation. I have recovered from those things. I just started Herceptin and the hormone blockers.

Hi Joy, at age 62, I was diagnosed HER2+ Stage 2, Grade 3, one tumor 2.7 cm.

The mammo was late November 2018, and surgery in December,
Chemo (Taxotere, Carboplatin, Herceptin) started Jan 2019
I finished active treatment (continuing Herception infusions every 3 weeks) late January 2020- so far, so good.

A 25% recurrence rate, means a 75% cancer-free rate! Keep the faith! Hugs!

- Factors Increasing Risk: Lymph node involvement, larger tumor size, and diagnosis at age 50 or younger increase the risk of recurrence.

Regular follow-ups and self-exams are crucial for early detection and treatment.
