Five important things you need to know about breast cancer

About breast cancer

One in 14 ladies in Hong Kong is diagnosed with invasive breast cancer, making it the most common cancer among females in Hong Kong. Fortunately, with modern screening tools and treatment options, the survival rate of breast cancer is high.

General surgeon, Dr. Mandy Wong, shares the five most important things we need to know about breast cancer.

1. Breast cancer symptoms

Symptoms may not show up during the early stages, it is usually when cancer grows larger that symptoms start to appear. Being familiar with the breast helps to recognize changes early and can make a big difference in treatment options. If you notice any of the symptoms mentioned here, seek medical attention as soon as possible:

  • A lump or thickening in or near the breast or under the armpit
  • A change in the size or shape of the breast
  • A change in the way the breast or nipple looks or feels
  • Ridges or pitting of the breast- the skin resembles the surface of an orange
  • Nipple discharge, pain, or scaliness; the nipple may also become inverted or pulled back into the breast

2. Updated breast cancer screening guidelines

The recommendation by the Cancer Expert and Screening (CEWG) in 2021, is that women aged over 44 should consider having a mammogram every two years if they have the below risk factors:

  • A history of breast cancer among a first-degree relative
  • Prior diagnosis of benign breast disease
  • No previous pregnancy
  • Late age of first live birth
  • Early age of first menstrual period
  • High Body Mass Index (BMI)
  • Physical inactivity

Women with the BRACA 1 or BRACA 2 gene mutation or a strong family history of breast and ovarian cancer should have a mammogram.

Mammogram vs ultrasound is a question that often comes up. An Ultrasound is used to screen for breast cancer but the CEWG suggested that it is not as effective as a screening tool. It may, however, help to assess an abnormality seen on mammography and to clarify features of a potential lesion. It may also be considered in women with very dense breasts that affect the sensitivity of mammogram assessment.

3. Nine out of 10 women with an abnormal mammogram do NOT have breast cancer.

If the result of the mammogram is abnormal, don’t panic. Depending on the doctor’s assessment, more diagnostic tests might be needed in order to investigate the abnormality.

An example would be a breast biopsy where a small amount of tissue from the breast is taken out through a fine needle and sent to a laboratory to test for the presence of cancer cells.

If the doctor thinks that the abnormal result is unlikely to be cancer, they may suggest monitoring and repeating the mammogram in 6 months.

4. Breast cancer treatment 

Surgery to remove the tumour is often the first line of treatment. The extent of the surgical treatment will depend on the situation and stage of breast cancer. The breast surgeon will discuss the most suitable surgical plan.

Surgery may be followed by chemotherapy, radiotherapy, hormone or targeted therapies and will involve a team of health professionals to ensure the best treatment outcome.

Early diagnosis is the key to the success of treatment, so a regular health check with breast screening is essential.

5. Reducing the risk of breast cancer?

For women with breast cancer genes BRCA1 and BRCA2 mutation, genetics have the strongest influence in their risk of breast cancer. For others, maintaining a healthy lifestyle and being aware of the following points can help you: 

  • Limit alcohol to 1 drink per day
  • Maintain a healthy BMI and body fat percentage
  • Be physically active and exercise at least 30 minutes a day, 3 days a week
  • Breastfeed your baby where possible
  • Discuss the risk with the doctor before starting hormonal therapy

It is important to keep in mind that by the time symptoms are noticeable it may be harder to treat. Regular health checks and breast screening play a crucial role in protection and prevention.
