Read this article below to find out more about the relationship between alcohol consumption and breast cancer, as distinguished consultant medical and clinical oncologist, Dr Shiroma De Silva-Minor, explains all.
Is there a link between alcohol consumption and breast cancer?
I find that many of my breast cancer patients have been unaware of the link between alcohol and breast cancer. Research has consistently shown that alcohol consumption is a known risk factor for breast cancer.
In terms of breast cancer, how does alcohol affect the body?
Alcohol consumption has been shown to increase the levels of oestrogen and other hormones in the body, which can contribute to the development of breast cancer. Additionally, alcohol can damage DNA in cells, which can also increase the risk of cancer.
Can moderate alcohol intake increase one’s chances of getting diagnosed with breast cancer?
The risk of breast cancer increases with the amount of alcohol consumed. Even moderate alcohol consumption has been shown to increase the risk of breast cancer. The Life after Cancer Study published in the Journal of Clinical Oncology found that even as little as three to four drinks per week could increase the risk of breast cancer recurrence. Although this may be too low for some, I believe in arming my patients with knowledge to allow them to make an informed choice about lifestyle.
Apart from breast cancer development, in what other ways can alcohol affect the body?
Alcohol can have any other adverse health effects for breast cancer patients, including increasing hot flushes, insomnia, bone thinning, and increasing the risk of osteoporotoc fractures, depression, addiction, and a bad body image.
What are the other main risk factors for breast cancer?
It is important to note that alcohol consumption is not the only risk factor for breast cancer. Many other factors, such as age, family history, obesity, the number of children or never being pregnant, and hormonal factors, are just some of the factors that can contribute to the development of breast cancer.
While it's difficult to completely eliminate the risk of breast cancer, reducing alcohol consumption can help lower the risk. Additionally, there are other lifestyle changes such as regular exercise and a healthy diet, that can help lower the risk of breast cancer and improve overall health. As a breast oncologist, I encourage my patients to be mindful of their alcohol consumption and to adopt a healthy lifestyle to reduce their risk of breast cancer and other chronic diseases.
