Breast cancer treatment combines several approaches, chosen according to the stage of disease, the cancer subtype (hormone receptor, HER2, or triple-negative), and each patient's situation. The goals are to remove the cancer, reduce the risk of recurrence, and preserve quality of life. This guide brings together every treatment option in one place, with links to read each topic in detail.
What does treatment depend on? (Stage and subtype)
The plan depends on the stage (see breast cancer staging) and the subtype — for example HER2-positive, triple-negative (TNBC), or early-stage DCIS — each of which is treated differently.
Surgery
Surgery is often the main treatment, either breast-conserving or mastectomy. Read how the approach is chosen in the guide to breast cancer surgery, and see where the journey begins in the screening & diagnosis guide.
Chemotherapy
Used for certain stages/subtypes, before or after surgery. Read more in chemotherapy overview and AC chemotherapy.
Radiation and IORT
Radiation lowers recurrence, especially after breast-conserving surgery. Namarak offers intraoperative radiation therapy (IORT) with Intrabeam 600, delivered during the operation itself.
Hormone and targeted therapy
Hormone-receptor-positive cancers use endocrine therapy such as Tamoxifen, while HER2 cancers use HER2-targeted therapy. For immunotherapy and mRNA, careful judgement is still needed.

Frequently asked questions about breast cancer treatment (FAQ)
Is breast cancer curable?
Yes — especially when found early, cure rates are very high. The chance of cure depends on the stage and subtype of the cancer and on receiving appropriate treatment.
How many types of treatment are there?
Six main groups: surgery, chemotherapy, radiation, hormone therapy, targeted therapy, and immunotherapy. Several are often combined in a personalised plan.
Does everyone need chemotherapy?
No. It depends on stage, subtype, and recurrence risk. Some patients have hormone or targeted therapy instead of, or in addition to, chemotherapy.
How does subtype (hormone/HER2/TNBC) affect treatment?
The subtype determines the drug regimen: hormone-receptor-positive cancers use endocrine therapy, HER2 cancers use targeted drugs, and TNBC usually relies on chemotherapy and newer options.
What is neoadjuvant therapy?
It is giving treatment (such as chemotherapy) before surgery to shrink the tumour and assess its response, which can make surgery easier in some cases.
What treatments are available at Namarak Hospital?
Namarak offers surgery, IORT (Intrabeam), chemotherapy, hormone therapy, and targeted therapy, delivered by a dedicated multidisciplinary breast team.
