Treatment Options for Breast Cancer: Surgery, Radiation, and Beyond

Getting a breast cancer diagnosis can feel like the ground has been pulled out from under you. What’s next? What are your options? With so many treatments available today, it’s natural to feel overwhelmed. But let’s walk through them together—from the familiar choices like surgery and radiation, to newer, more targeted therapies that offer hope beyond the standard route.


When Is Treatment Needed? Understanding the Stages

Before deciding on treatment, doctors usually look at how far the cancer has spread—its stage. Why does this matter? Because breast cancer isn’t one-size-fits-all. A small lump caught early may need very different care compared to cancer that has spread beyond the breast.

  • Stage 0 or I: Often treated with surgery alone, sometimes followed by radiation.
  • Stage II or III: May require surgery plus chemo, radiation, or hormone therapy.
  • Stage IV: When cancer has spread, treatments aim to control the disease, not cure it.

Knowing your stage helps your doctor—and you—map out the best plan. Don’t be afraid to ask questions. “Why this treatment? What are the risks? What if I wait?”


Surgery: What Are Your Options on the Table?

Surgery remains one of the first steps for many. But it’s not just about “removing the lump.” There are choices here, too:

  • Lumpectomy: Just the tumour and a small margin of tissue are taken out. Breast-conserving.
  • Mastectomy: The whole breast is removed. Sometimes it’s necessary if the cancer is large or widespread.
  • Sentinel lymph node biopsy: This checks whether cancer has spread to nearby lymph nodes.
  • Breast reconstruction: Can be done during mastectomy or later. You do have time to think this one through.

Here’s the thing—surgery isn’t just medical, it’s deeply emotional. Some women want to “take it all out.” Others prefer to keep as much of their breast as possible. There’s no right or wrong here, just what feels right for you.


Radiation Therapy: What to Expect and Why It’s Done

If surgery removes the visible cancer, radiation deals with any stray cells left behind. But how does it work?

Radiation uses high-energy rays (like X-rays) to target and destroy cancer cells. It’s usually done:

  • After a lumpectomy to lower the risk of recurrence
  • After a mastectomy if the tumour was large or involved lymph nodes

What should you expect? Sessions typically last just a few minutes, but they’re done daily for several weeks. Side effects might include fatigue, skin changes, and swelling—but most people manage them well.

It can feel like a grind, showing up every day. But try to remember—it’s short-term effort for long-term peace of mind.


Chemotherapy: Not Just for Advanced Cancer

Think chemo is only for late-stage cancer? Think again.

Chemotherapy is often used to:

  • Shrink a tumour before surgery (neoadjuvant)
  • Kill leftover cells after surgery (adjuvant)
  • Control the disease when it has spread

It travels through the bloodstream, so it can reach cancer cells all over the body. Common drugs include doxorubicin, cyclophosphamide, and taxanes. Side effects vary but may include:

  • Hair loss
  • Nausea
  • Lowered immunity

Sounds harsh? Yes—but it can save lives. And modern anti-nausea meds and supportive care have made it much more tolerable.


Hormone Therapy: Blocking the Fuel for Cancer Growth

Some breast cancers feed on hormones like estrogen or progesterone. If your cancer is hormone-receptor-positive, you’re likely to benefit from hormone-blocking treatment.

  • Tamoxifen: Blocks estrogen receptors. Often used in premenopausal women.
  • Aromatase inhibitors (AIs): Lower estrogen levels. Common for postmenopausal women.
  • Ovarian suppression: Stops the ovaries from producing estrogen (e.g. through injections or surgery).

These treatments don’t work overnight—they’re usually taken for 5–10 years. Think of it as a long-term strategy to keep the cancer from coming back.

But yes, there are side effects—hot flashes, mood swings, joint aches—but many women find ways to cope. And the benefit? A significantly reduced risk of recurrence.


Targeted Therapy: Precision Weapons Against Cancer Cells

We’re now in the era of precision medicine. Instead of blasting all fast-growing cells (like in chemo), targeted therapy aims at specific cancer cell features.

  • HER2-positive cancers can be treated with drugs like trastuzumab (Herceptin) or pertuzumab.
  • These drugs block the HER2 protein, which helps cancer cells grow.

Other options target specific mutations (like BRCA or PIK3CA). Your oncologist might order genetic tests to see if these therapies fit your tumour profile.

Less collateral damage, more accuracy—that’s the promise.


Immunotherapy: Can Your Immune System Help Fight Cancer?

Can your own immune system help fight cancer? That’s the idea behind immunotherapy.

While still relatively new in breast cancer, some triple-negative breast cancers (a more aggressive type) have responded well to drugs like atezolizumab or pembrolizumab.

These medicines help “unmask” cancer cells so your immune system can recognise and destroy them. It’s not a fit for every case—but if you’re eligible, it may offer new hope.


Complementary and Supportive Therapies: The Bigger Picture

Let’s be real—breast cancer treatment isn’t just about shrinking tumours. It’s also about keeping your mind, body, and spirit strong.

  • Physical therapy for strength and mobility after surgery
  • Nutrition support to maintain energy
  • Counselling or support groups to deal with the emotional rollercoaster
  • Acupuncture, massage, yoga – not cures, but they can improve quality of life

Never feel guilty about needing rest. Healing is work too.


Final Thoughts: Your Treatment, Your Terms

No two breast cancer journeys are the same. What matters most is making choices that align with your values, goals, and lifestyle. Yes, listen to your doctor. But also listen to your gut.

Need more time to decide? Ask. Confused by options? Bring someone with you. Scared? That’s human. But know this—you don’t have to face it all alone.
