Breast cancer is the most common cancer among women in Singapore today, with one out of 13 women likely to be afflicted by it. The incidence is growing with modern fast paced lifestyles including rich food, unhealthy diets, and increasing alcohol consumption by women.

Breast cancer often happens in women with no risk factors, but you can help yourself by adopting the following habits all year long for optimum breast health: observe, self-examine, screen.

Although most lifestyle factors influence risk of breast cancer only to a minor extent, here are some tips offered by the Division of Medical Oncology from National Cancer Centre Singapore (NCCS), to help keep your breasts and body healthy. NCCS is a member of the SingHealth group.

7 Tips to lower breast cancer risk

  1. Maintain a healthy body weight
    Maintain a BMI less than 23 throughout your life. Weight gain and obesity may increase your risk of breast cancer. Be aware: Fat is not inert. Fat deposited in the organs produce substances that cause inflammation and damage to multiple organs.

  2. Make time for regular exercise. Break it up to make it up
    Adopt an active lifestyle. Aim for 30 minutes or more of moderate aerobic activity at least five days per week. Here’s a tip from our doctors: If you cannot devote the time for a full workout, keeping active by walking and stretching for 10 minutes before each meal each day also helps! Remember - every bit counts towards a healthier you.

  3. Minimise or avoid alcohol
    Alcohol is one of the most well-established dietary risk factor for breast cancer. Women who consume more than two glasses of alcohol a day are at higher risk.

  4. Eat more veggies to boost your immune system
    Consume more cruciferous vegetables (broccoli, cabbage, cauliflower), dark leafy greens, carrots, tomatoes, citrus fruits, berries and cherries. Cruciferous vegetables are a rich source of glycosylates, which may help fight cancer. Local leafy greens such as Kai Lan and Spinach are high in healthy fibre, contain healthy nutrients like Vitamins A and C, which act as antioxidants that can protect your body, may help boost the immune system and reduce risk of cancer.

  5. Target motherhood
    Target to have your first child before 30. Mothers who breastfeed their babies for six months or longer may have a slightly lower risk of developing breast cancer.

  6. Early detection is your best protection
    Breast self-examination is recommended once a month about 1 week from the first day of menses. For women who no longer menstruate, choosing a date each month is an easy way to remember. Be sure to notify your doctor any breast changes such as redness, swelling, presence of a lump, skin changes or discharge from the nipple. For how to perform breast self-examination, see below.

    For women between the ages of 40 to 50: a mammogram every year after consultation with their doctor

    For women above the age of 50: a mammogram once every two years

  7. Quit smoking (if you haven't)
    The risk of many cancers, including breast cancer, and other health problems increases if you smoke.

When it comes to breast cancer, apart from lowering your risk, early detection is your best protection!

How to perform breast self-examination

(To perform once a month, 7 to 10 days after the start of your period)

1. Look for changes in front of a mirror. First, with arms at your sides. Next, with arms raised above your head. Finally, with hands pressed firmly on hips and chest muscles contracted

In each position, turn slowly from side to side and look for:

  • Change in size or shape of your breasts

  • Dimpling of the skin

  • Change in nipples

2. Feel for the changes lying down. Put a small pillow under your right shoulder. Place your right hand under your head

Use the pulp of your left fingers to feel for any lumps or thickening in your right breast. Feel for the changes lying down. First, feel the armpit. Then start on the outside edge of your breast and feel round the whole breast in smaller and smaller circles. Finally, feel behind the nipples itself.

3. Prepare for screening

On the day of screening:

  • Wear a two-piece outfit as you will need to undress from the waist up.

  • Do not use any perfume, deodorant, powder or ointment on your underarms or breasts as this may affect image clarity.

4. After the screening

  • If your results are normal (do not need to follow up at the hospital), continue to go for regular screening at the recommended frequency.

  • If your results are abnormal, you will be referred to a hospital to have further investigations done. It is important for you to attend this follow up at the hospital.

What puts you at risk of breast cancer? 

Dr Lim Geok Hoon, Senior Consultant for KK Breast Centre at KK Women's and Children's Hospital (KKH), a member of the SingHealth group, shares the risk factors for breast cancer.

As a woman, your risk of developing breast cancer is higher if you:

  • Are > 50 years old

  • Have a close relative (mother, sister or daughter) who has breast cancer or if you have a genetic mutation

  • Have taken hormone replacement therapy for more than 5 years after menopause

  • Have previous breast biopsies that have shown abnormal results

  • Had specific types of radiotherapy for lymphoma.

Breast cancer risk is also increased, though less markedly, if a woman:

  • Has never been pregnant or had her first pregnancy after the age of 30

  • Began to menstruate before the age of 12, or reached menopause after the age of 55

Do bear in mind that breast cancer can affect anyone at any time, even in the absence of high-risk factors.

Early signs of breast cancer to watch out for

Early detection saves lives. When breast cancer is detected early, there are more treatment options, less radical surgery required and better chances of complete recovery.

The most common symptom of breast cancer is a lump in the breast. It is usually single, firm and often painless. Other tell-tale signs include:

  • Swelling on a part of the breast or underarm;

  • A previously protruding nipple that becomes inverted;

  • A persistent rash at the nipple or areola;

  • Bloodstained discharge from the nipple; and

  • A change in the size or shape of the breast=

  • A change in the colour or appearance of the skin of the breast such as redness, puckering or dimpling

Is preventive mastectomy advisable? 

Back in 2013, famous Hollywood actress Angelina Jolie made headlines when had both her breasts removed to reduce her high genetic risk of developing breast cancer. How common is preventive mastectomy in Singapore?

"In Singapore, preventive mastectomy is performed for rare patients who carry specific mutated genes," explains Dr Lim.

"Carriers of mutations in the BRCA1 or BRCA2 genes have more than a 50 per cent risk of developing breast cancer in their lifetime. When that mutation is detected, one of the recommendations would be to perform a preventive double mastectomy, usually when the woman is in her 30s," Dr Lim added.
