October is Breast Cancer Awareness Month, with pink ribbons galore! As doctors, we are commonly on the receiving end of all kinds of queries: “Doctor, will I get breast cancer?”, “Doctor, how can I reduce my risk?”

So here are seven interesting facts that might help you answer those questions better.

1. Breast Cancer Risk of Individual Women is Calculated Differently Here

A large prospective study started right here in Singapore in 1993, involving over 28,000 women1. Nearly twenty years later in 2012, the study reported that the commonly used Gail model for cancer risk didn’t work very well in Singapore. Not unexpectedly, an Asian-American model was determined to model individual cancer risk better. Full disclosure: our medical director was a senior author on that work then.

2. Family History of Breast Cancer is Much More Important Than Thought

Singapore’s best-known health correspondent summarized it best: “A Singapore woman with a mother, sister or daughter with breast cancer is four times more likely to get it too, compared to someone with no such family history… Previously, based on the Western yardstick, those with a family history were thought to have double the risk.”2

3. Mortality is Stable but Incidence is Rising

Good news and bad. Mortality from breast cancer in Singapore has been stable over the last couple of decades. The not-so-good news? We have the highest per capita incidence of breast cancer in Asia.3

4. Real Progress Has Been Made In Awareness

Sometimes, it’s helpful to reflect on how far we’ve come. In 2009, 91% of surveyed women in Singapore were aware that early-stage breast cancer is curable. This climbed up from 39% in a 1994 survey4. We think that’s something worthwhile!

5. The Jolie Effect Here: the Demand for Cancer Genetics

Between 2011 and 2014, cancer genetics consults in Singapore here shot up three times5! There’s actually a name even for this phenomenon: it’s called the Jolie effect6, and it was observed worldwide. The needs for better advice and tests continue to rise, as some new anti-cancer drugs have been shown to work better in these patients.

6. BRCA Founder Mutations Are Observed Here Too

Specialized knowledge of ethnicity and genetics helps better genetic testing. In fact, a founder mutation specific to Malays was first discovered right here in Singapore in 20037,8! As a lab headquartered right here, we’re focused on better understanding of genetics in a multi-racial region, Together with our scientific partners, we continue to publish work in top journals discovering even newer genetic markers of breast cancer. 9

7. Vegetables, Fruit and Soy Are Best

People hunger for sensible and practical advice. So here’s the makan advice, backed by a cohort study of 35,303 Singaporean post-menopausal women. Increased vegetables, fruit and soy intake are linked to reduced breast cancer risk10. Not a randomized trial, but you try making people eat celery or taking away their bak chor mee over five years!

So here you have it. Seven facts for this month. We hope this has been useful to you and your breast cancer patients!
