In some cases, women with breast cancer may have no symptoms, while some abnormalities they experience may not be cancerous.  However, it is important to seek medical attention when the following symptoms appear:

• Lump or thickening in the breast or armpit
• Nipple becoming dimpled, discharge from the nipple, or an ulcer on the nipple
• Red rash on the breast, with the appearance of orange peel 
• Breast pain

Breast cancer screening is used for the early detection of breast cancer and increases the chances of successful treatment.  The following methods can be performed to screen for breast cancer:

• Self-examination
• Mammogram: A mammogram is recommended for women aged 40 and older every 1-2 years. 
• Ultrasound and MRI: If a mammogram examinations shows an abnormality, ultrasound or MRI may be used to confirm the diagnosis.

Diagnosis of breast cancer is performed when an abnormal lump is found (from self-examination or x-ray) or a tiny speck of calcium is seen (on an x-ray).  After a suspicious lump is found, the doctor will conduct a diagnosis to determine whether it is cancerous and, if so, whether it has spread to other parts of the body.  The most accurate method of diagnosis is a biopsy.  However, if a biopsy is not possible, the doctor will use an alternative test method. 
 
The method of cancer diagnosis varies depending on several factors, such as age, current medications, type of cancer, severity of symptoms and earlier test results.  Diagnosis of breast cancercan be performed in the following ways:

• Diagnostic Radiology
  • Diagnostic Mammography
  • Ultrasound
  • MRI
• Biopsy
• Surgical Pathology
• Blood Test
• Additional Tests
  • Chest X-ray
  • Bone Scan
  • CT Scan to generate 3D images of the organs to check for the spread of cancer. 

Treatment of breast cancer requires a multidisciplinary team of physicians such as surgeons, radiologists and cancer specialists, who together will make the most suitable treatment plan for each individual patient.  The doctors will make their decision based on the following factors:

• Size, location and characteristics of the cancer cells
• Stage and spread of the disease 
• Age and health of patient
• Hormone receptors
• Pre- or post-menopause  
• Factors indicating disease severity, such as the HER2 gene

• Surgery  
• Radiotherapy
• Chemotherapy
• Hormonal Therapy
• Targeted Therapy
