Below, week by week, is what OnCo's record of Early HER2-positive breast cancer says about the first two months: the order is typical, the timing is yours to ask about. HER2-positive breast cancer caught early is usually cured. Chemotherapy with the antibodies trastuzumab and pertuzumab comes before surgery; if the tumour has gone by then, antibodies alone finish the year, and if cancer remains, trastuzumab emtansine or trastuzumab deruxtecan take over. Small tumours get a gentler regimen, and trials now ask how much treatment can be left out. Sections appear only where the record has something to say. Orientation, not medical advice.
Staging tests establish exactly what and where the cancer is. Everything else follows from the answers.
Ask which of these were tested and what the results were; see the report reader for what each value means.
These specialties appear in the standard of care for this cancer. In most centres they meet weekly as a tumour board to agree each plan; you can ask when yours was discussed and what was decided.
A second opinion from a centre that treats many similar cases is normal, not rude; the standard of care tells you what to compare it against.
Each row is a setting from the standard of care, in the order it usually arises. Not all will apply to you; your stage and biomarkers decide which do. The guideline grade, where recorded, says how strong the evidence is.
Surgery first, then twelve weeks of paclitaxel with a year of trastuzumab (APT).
Carboplatin, a taxane, trastuzumab and pertuzumab for six cycles without an anthracycline (TRAIN-2), or trastuzumab deruxtecan followed by taxane, trastuzumab and pertuzumab (DESTINY-Breast11).
Trastuzumab, with pertuzumab in node-positive disease, to complete one year (APHINITY, HERA); endocrine therapy if hormone receptor-positive.
Trastuzumab deruxtecan (DESTINY-Breast05) or trastuzumab emtansine for fourteen cycles (KATHERINE).
Breast conservation or mastectomy with sentinel node biopsy, radiotherapy by stage, and echocardiography every three months during trastuzumab.

Trials open now for this cancer in OnCo, largest phase first. Joining a trial is a decision like any other: ask what the comparison arm is, whether a placebo is used, and what happens if you leave. The cancer page searches ClinicalTrials.gov live for more.
Much of what helps in the first weeks is free if you know to ask: testing, helplines, rides and lodging, second opinions, trial travel.
