Available Breast Cancer Medications: A Guide to Treatment Options
When it comes to breast cancer, no two cases are the same — and neither are the treatments. One of the biggest components of any treatment plan is medication. From hormone blockers to targeted therapies, the range of available breast cancer medications continues to expand and save lives. Here’s what you need to know about your options.
Why Medication Is Key in Breast Cancer Treatment
Medications help destroy cancer cells, shrink tumours, prevent recurrence, and improve survival rates. Some drugs are used alone, while others work best alongside surgery or radiation.
Main Types of Breast Cancer Medications
1. Hormone Therapy
Used for hormone receptor-positive breast cancers (ER+/PR+). These drugs block oestrogen or lower its levels in the body.
- Examples: Tamoxifen, Anastrozole, Letrozole, Exemestane
- How it works: Slows or stops cancer growth by interfering with hormones
- Who it’s for: Mostly postmenopausal women, but also used in younger patients
2. Chemotherapy
Destroys fast-growing cancer cells. Often used before surgery (neoadjuvant) or after (adjuvant).
- Common drugs: Doxorubicin, Cyclophosphamide, Paclitaxel, Docetaxel
- Side effects: Hair loss, nausea, fatigue, lowered immunity
3. Targeted Therapy
Designed to attack specific cancer cells with less damage to healthy cells.
- HER2-positive drugs: Trastuzumab (Herceptin), Pertuzumab, T-DM1
- How it works: Binds to HER2 protein to block cancer growth
4. CDK4/6 Inhibitors
Slows cancer cell growth by targeting specific proteins involved in cell division.
- Examples: Palbociclib, Ribociclib, Abemaciclib
- Used with: Hormone therapy for advanced or metastatic breast cancer
5. Immunotherapy
Boosts your immune system to fight cancer more effectively.
- Example: Atezolizumab (for triple-negative breast cancer with PD-L1 expression)
- Often combined with: Chemotherapy
6. PARP Inhibitors
Targets cancer cells with BRCA gene mutations by interfering with their DNA repair process.
- Examples: Olaparib, Talazoparib
- Who it helps: Patients with inherited BRCA1 or BRCA2 mutations

Side Effects to Watch Out For
- Fatigue
- Hair loss
- Nausea or vomiting
- Joint pain
- Hot flashes (with hormone therapy)
- Low white blood cell counts
Always discuss side effects with your doctor. Many can be managed with supportive medications or lifestyle changes.
Which Medication Is Right for You?
That depends on several factors:
- Cancer type (hormone receptor status, HER2 status)
- Stage and grade of cancer
- Genetic test results (e.g. BRCA mutations)
- Overall health and age
- Past treatments and current symptoms
Real-Life Examples
- 🎗️ A 45-year-old woman with ER+/HER2– breast cancer responded well to tamoxifen combined with Palbociclib, showing tumour shrinkage within months.
- 🎗️ A patient with a BRCA1 mutation saw success with PARP inhibitors after surgery and chemo, avoiding recurrence two years post-treatment.
FAQs
Q: Do I need to take medication after surgery?Often, yes. Medications help prevent recurrence based on your cancer’s characteristics.
Q: Will I need to take medicine for life?Hormone therapy can last 5–10 years. Other treatments vary based on cancer stage and response.
Q: Can I switch medications if I experience side effects?Yes, talk to your oncologist about alternatives. Many drug options exist today.
Q: Are there generic versions of these drugs?Some are available as generics, which may lower costs. Your provider or pharmacist can help.
Q: Can lifestyle changes replace medication?No, but healthy habits can support your treatment and improve outcomes alongside medication.
