Treatment typically begins one month after a lumpectomy or mastectomy and continues for around four to six months. 10 Chemotherapy for Cancer Treatment - An Overview HER2-Targeted Therapies
Full Answer

Systemic therapy (drugs that travel to almost every part of the body) is recommended for some women with stage II breast cancer. Some systemic therapies are given before surgery (neoadjuvant therapy), and others are given after surgery (adjuvant therapy).
What are the treatment options for HER2+ breast cancer?
Most common: neoadjuvant chemotherapy plus HER2-targeted therapy. Most people with HER2+ breast cancer, including those with very small tumors, use this plan. After surgery, they’ll get adjuvant therapy with HER2-targeted therapy. Less common: surgery, followed by adjuvant treatment with chemotherapy and HER2-directed therapy.
When should chemotherapy start after breast cancer surgery?
Ideally, it would seem that chemotherapy should be started if at all possible within 30 days of surgery, especially for those who have high risk tumors. There is little research looking at the optimal time until treatment for metastatic breast cancer, though it appears that waiting more than 12 weeks has been linked with lower survival.
What is the optimal time until treatment for metastatic breast cancer?
There is little research looking at the optimal time until treatment for metastatic breast cancer, though it appears that waiting more than 12 weeks has been linked with lower survival. In general, however, the goal of treatment with MBC is different than early stage disease.
How soon after breast cancer diagnosis should treatment start?
In some situations, your doctor may diagnose a new primary cancer instead of a recurrence. If so, you should wait no more than 2 months (62 days) to start treatment. This time starts on the date that the hospital has received an urgent referral for suspected cancer.
DOES HER2-positive breast cancer always require chemo?
The treatment of HER2-positive breast cancer will depend on your preferences as well as the characteristics of your cancer: Many women with HER2-positive breast cancer will get neoadjuvant chemotherapy first, along with medication that targets HER2 directly (see 'Chemotherapy' below and 'HER2-directed therapy' below).
How long is the treatment for HER2-positive breast cancer?
Trastuzumab is given intravenously (with an IV) weekly or every 3 weeks. As an adjuvant therapy, one year of treatment of treatment is typical. Multiple studies show that trastuzumab can dramatically improve survival. In fact, trastuzumab-based treatments for HER2+ breast cancer are considered the gold standard.

Current treatment algorithms for invasive HER2-positive disease has transformed the face of a disease with a death sentence to one with prolonged and overall survival benefit.
Is Stage 2 HER2-positive breast cancer curable?
HER2-positive breast cancer is highly curable because of the availability of these HER2-targeted therapies, so we treat patients fairly aggressively upfront to reduce the risk of them experiencing a stage IV recurrence.

What percentage of breast cancer cases are positive for a mutation?
It's believed that around 20-25% of newly diagnosed cases of breast cancers are positive for a genetic mutation that causes HER2 gene amplification. 3 The mutation causes the gene to produce too many HER2/neu proteins (or just HER2 proteins).
