🩷 BREAST CANCER PREVENTION AND RISK 🩷
Breast cancer is the most commonly diagnosed cancer amongst women in Australia.
It is estimated that 1 in 7 women will be diagnosed with breast cancer in their lifetime.
Directly – or indirectly – more Australian families are likely to be affected by breast cancer than any other type of cancer.
There are a range of factors that contribute to your chance of developing breast cancer. Some risks can be reduced, while others you might have no control over.
👉HOW TO MINIMISE YOUR RISK OF DEVELOPING BREAST CANCER
The number of new cases of breast cancer is predicted to increase year on year. And while there are many risk factors that we have no control over, such as being a woman, or getting older, there are others which can be changed or managed.
The following lifestyle factors have been linked to breast cancer risk. Although these may increase your risk of developing breast cancer, having one or more of these risk factors does not mean that you will definitely develop cancer. Likewise, having no known risk factors also does not guarantee that you will never develop cancer. If you are concerned about any of these risk factors, see your doctor to discuss any concerns prior to making lifestyle changes.
👉Alcohol intake
Drinking alcohol is associated with an increased risk of breast cancer, and with breast cancer returning. The risk of breast cancer rises as the number of drinks regularly consumed increases. Currently, there does not appear to be a ‘safe’ level of regular alcohol consumption. According to Cancer Australia, approximately 6% of breast cancer cases each year in Australia are due to alcohol consumption.
👉 Being overweight
For women who have experienced menopause (postmenopausal women), being overweight or obese, or gaining weight, is linked to an increased risk of breast cancer. Keeping to a healthy weight range reduces the risk of breast cancer. According to Cancer Australia, it is estimated that 8% of postmenopausal breast cancers each year in Australia are due to being overweight or obese.
👉 Physical activity
Physical activity is associated with a reduced risk of breast cancer. Active women of all ages have a decreased risk of breast cancer compared to women who do not exercise. The more physically active you are, the greater the health benefits. Cancer Australia states that approximately 8% of postmenopausal breast cancers each year in Australia are due to a lack of physical activity.
👉Having children and breastfeeding
Having children is linked to a reduced risk of breast cancer. According to Cancer Australia, the risk of breast cancer decreases by 7% for each child the women has had. Breastfeeding is probably associated with a small decreased risk of breast cancer as well – the longer the duration of breastfeeding, the lower the risk of breast cancer.
It is thought that the changes which occur in cells of the breast during a full-term pregnancy or breastfeeding may make the cells less likely to become cancerous. This may explain why women who have had children or have breastfed have reduced breast cancer risk.
👉 Smoking (inc Va**ng)
There is evidence that suggests an association between smoking and breast cancer risk. There may be an increased risk of breast cancer for women who started smoking at a very early age, or for many years before their first child. However, to***co smoke contains more than 70 chemicals that are known to cause cancer; smoking is also known to cause cancer of many organs of the body including lung, throat, liver, bowel and bladder cancers.
