What is Breast Cancer?

Breast cancer is one of the most common cancers affecting women in Philippines and worldwide. It begins when abnormal cells in the breast grow uncontrollably and form a lump or tumour. Although breast cancer mainly affects women, men can also develop the disease. The three main subtypes are hormone receptor positive (ER/PR-positive), HER2-positive, and triple negative breast cancers. Each type behaves differently and requires specific treatment approaches.

How common is breast cancer in the Philippines?

Breast cancer is the most common cancer among women in the Philippines, accounting for about 1 in 3 new cancer cases in women.  

According to the IARC Global Cancer Observatory (GLOBOCAN 2022): 

  • Breast cancer made up 31.2% of all new cancer cases among women in the Philippines in 2022 (33,079 cases). 
  • The age-standardized incidence rate (ASR) for breast cancer among women was 60.3 per 100,000. 
  • Breast cancer was also a leading cause of cancer deaths nationwide, with an estimated 11,857 deaths in 2022.  

For comparison, cervical cancer was the third most common cancer among women in the Philippines in 2022, with 8,549 new cases and 4,380 deaths.  

These figures highlight why early detection and timely treatment of breast cancer remain crucial to improving outcomes and quality of life for Filipino patients and families. 

What Are the Signs and Symptoms of Breast Cancer?

Some common signs to look out for include:

Early breast cancer may not show symptoms, which is why regular screening, such as mammograms, is important for early detection.

Screening for Breast Cancer

Regular screening is the most effective way to detect breast cancer early, when treatment works best. In Philippines, breast cancer is often diagnosed at a later stage, making awareness and timely screening especially important.

Screening Options
  • Mammogram: The gold standard for breast cancer screening, recommended for women aged 40 and above, or earlier if there is a family history.
  • Ultrasound: Often used together with mammograms, especially for younger women or those with dense breast tissue.
  • Clinical breast examination: Performed by a doctor to check for lumps or changes in the breast.
  • Breast self-examination: Helps women become familiar with their own breast tissue and notice unusual changes, though it does not replace medical screening.
  • Women aged 40 years and above.
  • Women with a family history of breast or ovarian cancer.
  • Those with genetic risk factors, such as BRCA mutations.
  • Women with prior breast conditions or higher lifetime risk.
  • Detects cancer before symptoms develop.
  • Enables treatment at earlier, more curable stages.
  • Reduces the risk of advanced disease and improves survival outcomes.

How Breast Cancer is Diagnosed?

Diagnosis involves several steps:

What Are the Causes and Risk Factors of Breast Cancer?

What Are the Types of Breast Cancer?

  • Hormone receptor positive (ER/PR-positive): Cancers that grow in response to hormones
  • HER2-positive: Cancers driven by high levels of the HER2 protein, often more aggressive
  • Triple negative breast cancer: Lacks ER, PR, and HER2; tends to behave more aggressively
  • Less common types: Inflammatory breast cancer, Paget’s disease of the nipple, and male breast cancer

What Are The Stages of Breast Cancer?

Breast cancer stages range from early to advanced:
Stage 0

Ductal carcinoma in situ (DCIS), cancer confined to the ducts

Small invasive tumour with little or no lymph node involvement

Larger tumour or spread to nearby lymph nodes

Locally advanced, with more extensive lymph node spread or involvement of chest wall/skin

Cancer has spread (metastasised) to other organs, such as bone, liver, lung, or brain

What are Breast Cancer Treatments?

Treatment depends on cancer stage, subtype, and patient profile. In Philippines, there are various treatment options available for breast cancer. The specific treatment plan will depend on multiple factors, such as the cancer stage, the tumour grade, the patient’s overall health, and other individual factors.

Surgery

Lumpectomy (breast-conserving) or mastectomy, often with lymph node surgery.

Radiotherapy

To destroy residual cancer cells and reduce recurrence risk.

Hormonal Therapy

Tamoxifen, aromatase inhibitors, fulvestrant; sometimes combined with CDK4/6 inhibitors (Ibrance, Kisqali, Verzenio) for advanced cancer.

Targeted Therapy

HER2-directed treatments such as trastuzumab (Herceptin).

Immunotherapy

Used in certain triple negative breast cancers.
