Breast cancer is the most common cancer among women in Malaysia, with almost half of cases diagnosed at advanced stages, according to the figures cited in the original article. While a breast cancer diagnosis can bring fears of surgery, chemotherapy and a long road to recovery, advances in personalised medicine are changing how doctors approach treatment.

Today, breast cancer care is increasingly guided by the specific characteristics of each tumour, alongside a patient’s overall health, lifestyle and personal needs. This means that even women diagnosed with breast cancer at the same stage may require different treatment plans.

“Breast cancer is a group of different subtypes, and each behaves very differently. Some are responsive to hormones or overproduce a protein called HER2, which drives cancer cell growth. Others have none of these markers, which is known as triple-negative breast cancer,” she says.

Why Breast Cancer Treatment Differs from Patient to Patient

Although two patients may have tumours of a similar size, their treatment plans can differ significantly depending on the cancer subtype and other individual factors.

For example, a woman with hormone receptor-positive, HER2-negative breast cancer may undergo surgery, radiotherapy and hormone therapy. Another woman with a similar-sized but HER2-positive tumour may also require chemotherapy and HER2-targeted treatment.

“What may look similar on paper can behave very differently. Understanding what is driving the cancer helps us determine which treatment is most appropriate for each patient. We are not simply treating breast cancer; we are treating the person and their specific type of cancer,” Dr Nisha explains.

Treatment decisions also take into account age, overall health, menopausal status and personal preferences. This individualised approach helps doctors consider not only how to treat the cancer, but also how treatment may affect a woman’s quality of life.

Understanding Aggressive Breast Cancer Subtypes

Terms such as “aggressive breast cancer” can understandably cause anxiety. However, Dr Nisha explains that the term describes how a cancer behaves and grows, rather than determining a patient’s eventual outcome.

Triple-negative and HER2-positive breast cancers can grow more quickly than some other subtypes. However, they may also respond well to specific treatments, depending on the individual case.

“In the past, HER2-positive breast cancer used to carry a poor prognosis. With targeted therapy, outcomes have transformed dramatically and improved survival in many women with breast cancer,” she says.

Advances in personalised medicine have also introduced additional ways to guide treatment decisions. For selected patients, genomic testing can help estimate the likelihood of cancer recurrence and whether chemotherapy is likely to provide additional benefit.

Meanwhile, targeted therapies, more precise surgical approaches and advances in radiotherapy have expanded treatment options for many patients.

“We used to ask which treatment can give the best outcome. Now, the question is which treatment is most appropriate for my patient, and our focus has also shifted to patient survivorship,” Dr Nisha says.

Breast Cancer Screening in Malaysia: Why Early Detection Matters

Despite progress in breast cancer treatment, late diagnosis remains an important concern in Malaysia. Fear of discomfort, embarrassment or receiving an unexpected diagnosis can discourage some women from attending breast cancer screening.

However, early detection can increase the opportunity for timely treatment and may allow more treatment options, depending on the cancer’s characteristics.

“Don’t let fear make the decision for you. A lot of the fear is in the unknown. Knowledge is power,” Dr Nisha urges.

A mammogram can help detect breast cancer before symptoms develop. A normal result can also provide reassurance, although no screening test can detect every cancer.

For women who feel anxious about a mammogram, Dr Nisha suggests bringing a trusted friend or family member for support. Women who notice a breast lump or other unusual changes should seek medical assessment rather than waiting for their next screening appointment.

Breast Cancer Care Goes Beyond Treatment

Modern breast cancer care extends beyond surgery, chemotherapy, radiotherapy and other medical treatments. A multidisciplinary team may include oncologists, surgeons, radiologists, nurses and other healthcare professionals who work together to address different aspects of a patient’s care.

Support may also include managing treatment side effects, emotional wellbeing, fertility concerns, intimacy, returning to work and life after treatment.

These considerations are important because breast cancer affects more than a person’s physical health. Treatment can also influence confidence, relationships, family responsibilities and everyday routines.

“Cancer doesn’t define you. It is one chapter of your life, not the whole story,” Dr Nisha reassures.

Personalised breast cancer care therefore considers both the disease and the individual living with it, with the aim of supporting patients throughout treatment and survivorship.

Taking the First Step Towards Breast Health

Advances in breast cancer diagnosis and treatment have created more opportunities for care tailored to individual patients. Understanding the cancer subtype, assessing available treatment options and seeking medical advice early can help women make informed decisions about their health.

For women who have been putting off a mammogram because of fear, taking the first step can make a meaningful difference. Those who notice a lump, nipple changes or other unusual breast symptoms should seek prompt medical assessment.

“Most lumps are not cancer, but getting checked can provide answers. Fear is understandable, but don’t let it stop you from taking that first step for your health,” Dr Nisha urges.

Breast cancer treatment is no longer defined by a single pathway. With personalised treatment, multidisciplinary support and greater awareness of early detection, women can work with their healthcare teams to understand their diagnosis and make decisions suited to their individual needs.
