New research indicates that women should limit alcohol consumption to approximately six drinks annually. Exceeding this amount is linked to a noteworthy increase in cancer risk, particularly breast cancer. Learn more about the alcohol consumption guidelines and their impact on women’s health.
Alcohol and Cancer Risk in Women: Understanding the Guidelines
Updated estimations reveal that consuming more than six alcoholic beverages per year can elevate a woman’s lifetime vulnerability to developing cancer by as much as 27 percent. Conversely, adhering to six or fewer drinks annually increases the risk by a mere 0.3 percent – a figure deemed negligible by experts.
Breast Cancer: A Significant Concern
Breast cancer remains the most prevalent cancer among women in the United Kingdom, with approximately 55,000 new diagnoses each year. Sadly, around 11,500 individuals succumb to the disease annually.

While the correlation between even minimal alcohol intake and potential health risks has been long recognized, the World Health Organisation’s researchers have now quantified the risk associated with each alcoholic beverage consumed.
- One drink per week corresponds to a 3 percent increase in risk.
- More than six drinks per year elevates the risk to 2 percent per drink.
- Daily consumption of a small glass of wine (approximately 10 units per week) raises the risk by 15 percent.
- A large glass of wine daily, or around two bottles weekly (approximately 20 units), increases the risk by 27 percent.
This signifies that, among 100 women who consume alcohol at this higher level, 14 could anticipate developing the disease.
The Dangers of Binge Drinking
Binge drinking poses an equal threat. For women, this is defined as consuming six units in a single session – approximately two large glasses of wine.
- Regular weekend binge drinkers who consume eight medium glasses of wine over two days face a 24 percent greater risk of breast cancer.
- Even those who limit themselves to four glasses per weekend are 12 percent more likely to develop the disease.
Expert Insights on Alcohol Consumption and Cancer
Dr. Liz O’Riordan, a breast cancer specialist who has battled the disease three times, emphasized, “I knew the risks, and I ignored them. There is no safe level of alcohol consumption, and people need to be aware of that.”
She further stated, “The two most significant risk factors for developing breast cancer are age and being female, both of which are unchangeable – but you can control your alcohol intake.”
“Therefore, if you wish to lower your breast cancer risk, reduce your alcohol consumption.”
“The impact of alcohol intensifies with age, and it’s never too late to modify habits and reduce your risk.”
According to recent figures from the National Health Service (NHS), 81 percent of adults reported consuming alcohol in the past year, with men more likely to have done so than women (84 percent compared to 78 percent).
Current NHS Guidelines on Alcohol Intake
Currently, the NHS advises limiting alcohol consumption to 14 units per week – equivalent to six medium glasses of wine or six pints of beer.
- Men are more prone to exceeding this limit (32 percent) compared to women (15 percent).
- However, data from the Health Survey for England indicates that 55 percent of men and 42 percent of women consume alcohol at least once a week.
Experts suggest that the current “safe drinking” guidelines are outdated and fail to acknowledge the established link between alcohol and seven types of cancer.
“The national guidelines need revision to align with other countries, as there are no safe levels of alcohol,” asserts Dr. O’Riordan.
“The connection to cancer needs recognition. Occasional enjoyment of a glass of something you like, or six glasses annually, is acceptable, but avoid making it a habit.”
Professor Jayant Vaidya, an oncologist at University College London (UCL), part of its Tobacco & Alcohol Research Group, explains that the relationship between alcohol and breast cancer is ‘dose dependent’.
He notes: ‘When you have a glass of wine you are paying the price for the joy you are experiencing, with an increased risk of breast cancer.
‘It is dose dependent, so for every drink you have you are increasing your risk. You need to balance the risk and should reserve alcohol for special occasions only.’
However, some experts argue that entirely abstaining from alcohol or severely limiting intake may be excessively drastic and potentially counterproductive.
“A common-sense approach is essential,” states Professor Hendrik Tobias Arkenau, an oncologist at UCL.
“Of course, there is a risk associated with alcohol consumption, but one drink per week won’t significantly increase your risk.”
“Advising universal abstinence neglects alcohol’s cultural significance and will undoubtedly impact individuals’ quality of life.”
How Alcohol Affects Breast Cancer Risk
Alcohol increases breast cancer risk through two primary mechanisms:
- Firstly, it breaks down into acetaldehyde, a carcinogen that can damage DNA, including in breast tissue.
- Secondly, it elevates levels of oestrogen, a hormone known to stimulate the development and progression of numerous breast cancers.
Dr. O’Riordan further cautions that alcohol can increase breast density, a recognized risk factor for cancer.
Dense breasts can also complicate tumor detection through current screening methods.
Cancer Research UK estimates that 8 percent of annual breast cancer diagnoses in the UK are directly attributable to alcohol consumption.
Despite these findings, one in four adults in England exceeds the NHS’s recommended alcohol limit.
The Institute of Alcohol Studies estimates the average British woman consumes approximately nine units weekly, placing most within a 9 to 15 percent increased risk range.
Survival rates for breast cancer have doubled over the past 50 years, with three-quarters of women surviving at least ten years post-diagnosis, owing to improved screening and increased awareness.
Women are encouraged to self-examine their breasts regularly for cancer signs, including:
- Lumps or swellings
- Changes in size, shape, or color
- Nipple discharge
- A rash or crusting around the nipple
- Skin dimpling
- Persistent pain
Individuals with concerns are urged to consult their General Practitioner (GP), and those worried about their alcohol consumption can also seek support through their doctor.
Did Boozing in My 20s Cause My Breast Cancer?
Dr. Liz O’Riordan, a three-time breast cancer survivor, speculates that her earlier heavy drinking may have contributed to her cancer diagnosis.
‘I knew the risks, but I ignored them. I drank like a fish at medical school – we were told that alcohol raised cancer risk but it didn’t sink in,’ says Dr O’Riordan. ‘I have often wondered whether my own heavy drinking as a junior doctor might have played a part in my diagnosis.’
However, the former breast surgeon, who wrote The Cancer Roadmap, published in January, advises against feeling guilty about past drinking habits.
She added: ‘It is never too late to change your habits, and the risk compounds as you age so you need to be aware of it.
‘I’m not teetotal but I barely drink and I’m in the best shape of my life, but it has been a slog to get here.’
