7 things to know for breast cancer awareness month

October is Breast Cancer Awareness Month… a great reminder to take care of your breast health! Here, DR KYM CHEW, Family Physician at International Medical Clinic (IMC), shares her thoughts on a few everyday habits that can lower your risk of breast cancer.

Breast cancer is the most common cancer affecting women in Singapore – and rates are rising, especially among women under 50. While there’s no guaranteed way to prevent it, simple lifestyle habits can help lower your risk. The good news? Many are things you can start doing today.

Breast cancer awareness: 7 ways to lower your risk

#1 Move more, sit less

Regular physical activity is one of the best ways to lower breast cancer risk, particularly after menopause. Aim for 150 to 300 minutes of moderate activity (like brisk walking or swimming) each week. Even short walks add up.

#2 Maintain a healthy weight

After menopause, fat tissue becomes the main source of oestrogen, and higher levels can increase cancer risk. Gaining weight as an adult is especially linked to breast cancer, so try to stay active and eat a balanced diet.

#3 Limit alcohol intake

Even one drink a day raises your breast cancer risk by seven to 10 percent. Two to three drinks a day increases the risk by about 20 percent. It’s best to avoid alcohol, but if you do drink, limit it to no more than one drink a day.

#4 Breastfeed if you can

Breastfeeding is linked to a slightly lower risk of breast cancer. It also brings other health benefits for both mother and baby.

#5 Look at your hormones

Hormonal birth control and menopause hormone therapy can increase risk. Talk to your doctor about alternatives or use the lowest dose for the shortest time needed.

#6 Self-checks for breast cancer lumps

Regular self-checks encourage breast cancer awareness and help you get familiar with how your breasts normally look and feel. While it doesn’t prevent cancer, it helps you detect changes early – when treatment is most effective.

#7 Schedule regular screenings

Mammograms are recommended from age 40 in Singapore and are crucial for early detection. If you have a strong family history or dense breast tissue, ask your doctor if you need earlier or more frequent checks.

Final thoughts on breast cancer awareness

There’s no guaranteed way to prevent breast cancer, but being aware of breast cancer empowers us to take steps every day, from staying active and eating well to being aware of our bodies, that can make a real difference. If you’re feeling overwhelmed, just start with one habit. Small changes lead to big impact over time. When in doubt, speak with your family doctor.
