You can reduce your cancer risk if you drink less alcohol. Drinking no alcohol at all is even safer.
Why? Every drink increases your risk of getting an alcohol-related cancer. In fact, we know that alcohol causes more than 3,200 cancer cases in Australia each year.1 The bottom line is: there is no level of drinking that is completely safe.

How does drinking alcohol cause cancer?
There may be several ways that alcohol causes cancer. What we do know is that alcohol contains ethanol, which is a cancer-causing compound (a Group 1 carcinogen). When being broken down by the body, ethanol becomes a toxic chemical called acetaldehyde, which can damage the DNA of your cells causing cancer.
It does not matter the amount nor the type of alcohol you consume, your risk of getting cancer increases with every drink.4

Set yourself a limit and count your drinks
If you want to slowly reduce your alcohol consumption, there are some simple steps that can help. One of the best strategies is to set yourself a drink limit: every time you get a drink, take a note of what number drink it is. The Drinks Meter app by the NSW government is a great way to keep track of your drinks.
A good guide for setting your drink limit is to follow the National Health and Medical Research Council (NHMRC) Australian guidelines to reduce health risks from drinking alcohol.
For adults, set yourself a limit of no more than ten standard drinks over a week and no more than four on any day.
Anyone under 18 years of age along with women who are pregnant, breastfeeding or planning a pregnancy, should not drink at all.
Commit to having a few alcohol-free days each week
There are many health benefits to creating the habit of having a few alcohol-free days each week. Not only will you lower your cancer risk, you will also see immediate physical and mental benefits including better sleep, increased energy, and a balanced mood. Plus don't forget the cost savings!
Swap to low or no alcohol alternatives
Instead of alcohol, try reaching for a low or no alcohol alternative. Many low or no alcohol drinks look and taste the same or similar as your favourite drink.
Some popular alternatives include:
- soda water, which can be flavoured with citrus or a splash of juice
- non-alcoholic spirits – many are infused with botanicals or spice flavours
- low or no alcohol beer or cider or wine
- mocktails instead of cocktails
- sparkling juice
Adapt your routine
Giving up or changing a drinking habit can be extremely challenging. This is made only harder when alcohol is at the heart of so many social events, making it difficult to say no to a drink. In the first few weeks of trying to reduce how much you drink, it can help to avoid events where there is drinking.
Try to see your friends during the day rather than the evening. Have a picnic in the park with family rather than meeting where there are alcoholic drinks available. Swap after-work drinks at a pub for coffee at a café before work. Or meet up with a friend for a walk or a swim instead of heading out to a bar. For more ideas on social activities that don't involve drinking, take a look at these suggestions from Hello Sunday Morning.
Be aware of social pressure and have a plan
It is easy to be encouraged or to feel pressured into drinking, even when we tell our friends and family that we are drinking less for our health. Research shows peers can influence our drinking practices both directly and indirectly.5 Direct influences can be as clear as open encouragement to drink, buying someone a drink when they have said they do not want one, or subtle gestures to drink up. It is helpful to be aware of social pressure and to plan how you are going to respond.
Avoiding the pressure to drink can be as simple as planning an early start the next morning or heading home early. Remind yourself of the reasons you are cutting down or stopping drinking. A solid resolution to change your drinking can be a great aid in resisting the pressure to drink.
Create a support network
Setting up a personal support network or finding no drinking “buddies” can be extremely helpful to start and sustain a goal of reducing your alcohol intake. Telling people about your plans to stop drinking and being a part of a community with a shared goal can help you be accountable. Your support network does not have to be made up of just friends or family, it could be an online community.
What happens when you stop drinking alcohol?
Reducing your alcohol limit can help prevent cancer, but there are so many other benefits to stopping drinking. Quitting or reducing alcohol for as little as one month can improve your physical wellbeing, mental health and mood, productivity and focus, stability of relationships and money left in your pocket.6 Longer term change brings even greater benefits.
Important note: For some people, suddenly stopping drinking can make them feel physically and emotionally unwell. If you feel sick, sweaty or cannot sleep when trying to cut down on your drinking – you may be experiencing withdrawal symptoms and should see your doctor. If in doubt don’t stop drinking but seek medical advice
Reducing drinking during COVID–19
Research on alcohol consumption during the 2020 COVID-19 pandemic has shown encouraging results. While a third of people in NSW increased their drinking during the lock-down, two thirds of people drank less or the same amount of alcohol as before.
Reducing social pressures and occasions to drink may have been a key factor in helping some people to reduce their alcohol intake. 
If in the time of the pandemic you find yourself drinking more than usual, take a look at the following resources to help you reduce your drinking behaviours and stay healthy.
