Alcohol can increase your cancer risk. What experts say about how much is too much.
Despite growing research that points to the negative health impacts of alcohol, many Americans are unaware of the connection between drinking and cancer risk.
A recent report from the American Association for Cancer Research found excessive levels of alcohol consumption increase the risk for six different types of cancer, including:
“Some of this is happening through chronic inflammation. We also know that alcohol changes the microbiome, so those are the bacteria that live in your gut, and that can also increase the risk,” Dr. Céline Gounder, CBS News medical contributor and editor-at-large for public health at KFF Health News, recently said on “CBS Mornings.”
But how much is too much when it comes to drinking? We asked experts what to know:
How much alcohol is bad for you?
“Excessive levels of alcohol” equates to about three or more drinks per day for women and four or more drinks per day for men, Gounder said.
According to the National Institute on Alcohol Abuse and Alcoholism, a standard alcoholic drink contains 14 grams (or 0.6 ounces) of pure alcohol. Generally, this amount is found in 12 ounces of beer, 5 ounces of wine and 1.5 ounces, or a “shot,” of 80-proof distilled spirits or liquor.
Other studies have shown, however, there is no “safe amount” of alcohol, Gounder said, particularly if you have underlying medical conditions.
“If you don’t drink, don’t start drinking. If you do drink, really try to keep it within moderation,” she said.
Dr. Amy Commander, medical director of the Mass General Cancer Center specializing in breast cancer, told CBS News alcohol is the third leading modifiable risk factor that can increase cancer risk after accounting for cigarette smoking and excess body weight.
“There really isn’t a safe amount of alcohol for consumption,” she said. “In fact, it’s best to not drink alcohol at all, but that is obviously hard for many people. So I think it’s really important for individuals to just be mindful of their alcohol consumption and certainly drink less.”
How else can alcohol affect your health?
The benefits of limiting alcohol is not just about cancer risk. Alcohol in large or frequent amounts is considered toxic to the human body, said Dr. Angela Tatiana Alistar, medical director of GI Medical Oncology at Morristown Medical Center, Atlantic Health System.
“All organs can be affected by alcohol intake depending on dose and frequency,” she told CBS News. “There is vast scientific literature regarding the impact of alcohol consumption on the liver described as hepatitis (in the acute form), liver cirrhosis (chronic form) and possible liver cancer.”
Drinking alcohol can also have direct and immediate effects on other organs like the brain, affecting the sleep-wake cycle.
“It can also affect cognition, coordination and emotional regulation,” Alistar said. “Acute and chronic dependence and tolerance to alcohol is a high-risk factor for social functioning and mental health.”
Is wine healthy?
Some studies have suggested health benefits from drinking red wine. Occasional wine is also a part of the Mediterranean diet, which is often praised for a reduction in mortality, heart disease and more. But, other research says any potential benefit doesn’t outweigh the risks.
“A glass of red wine is included in terms of the alcoholic beverages that one should be mindful of — beer, red wine, other spirits,” said Commander. “There’s been at times this health halo about red wine, but when it comes to cancer, it is still considered alcohol and it should be limited.”
But, doesn’t everything cause cancer anyway?
Commander admits cancers are complex with many factors that can contribute to someone’s risk — but, at the same time, we’re making strides in cure rates and early detection.
For example, the latest Cancer Progress Report found a 33% reduction in the overall cancer deaths from 1991 to 2021.
“So that is hopeful,” Commander said, adding alcohol is just “one piece of the puzzle” in prevention.
“There are so many aspects of our lifestyle that we should focus on in order to optimize our health, certainly to reduce our risk of cancer, but also other chronic diseases, such as cardiovascular disease, Type 2 diabetes and other conditions that we face in this country,” she said.
Alistar recognizes social changes can be difficult when it comes to alcohol.
“Socializing with friends and family typically involves sharing food and drinks. Having open conversations about the impact of alcohol on general health with your family and friends would be a good way to start,” she said, but added “celebratory drinks or foods are OK in my opinion if most of the time one has a healthy diet and lifestyle.”
Other ways to decrease cancer risk
Reducing alcohol isn’t the only way to decrease your risk of cancer. There are several other modifiable risk factors that researchers found are linked to more than 40% of all cancer fatalities, including smoking, excess body weight, physical inactivity and diet.
Using sunscreen to prevent skin cancer and getting the HPV vaccine to prevent cervical cancer and oral cancer related to the human papillomavirus are other prevention measures, Gounder said.
Despite losing his boxing match to Jake Paul, Mike Tyson in a social media post Saturday said he had “no regrets” to getting “in ring one last time.”
The boxing legend was defeated by social media star Jake Paul in a highly anticipated fight on Friday night with an age difference of over three decades between the two contenders.
Netflix said Saturday that 60 million households worldwide tuned in to watch the match. The two fighters went eight full rounds, with each round two minutes long. Paul defeated Tyson by unanimous decision and the 27-year-old upset boxer and 58-year-old former heavyweight champion hugged afterward.
Paul was expected to earn about $40 million from the fight, and Tyson was expected to take around $20 million for the fight, according to DraftKings and other online reports.

Tyson said on his social media that “this is one of those situations when you lost but still won. I’m grateful for last night.”
The fight almost didn’t happen after Tyson experienced an ulcer flare-up while on a plane in March. He addressed his illness Saturday, writing that he “almost died in June.” He said he had eight blood transfusions and “lost half my blood and 25lbs in hospital and had to fight to get healthy to fight so I won.”
Tyson retired from boxing in 2005 after a 20-year career. He last fought in a 2020 exhibition match against former four-division world champ Roy Jones Jr.
“To have my children see me stand toe to toe and finish 8 rounds with a talented fighter half my age in front of a packed Dallas Cowboy stadium is an experience that no man has the right to ask for. Thank you,” he said.

In their final meeting, China’s leader Xi Jinping told U.S. President Biden that his nation was “ready to work with a new administration,” as President-elect Donald Trump prepares to take over.
The two leaders gathered Saturday on the sidelines of the annual Asia-Pacific Economic Cooperation summit. Mr. Biden was expected to urge Xi to dissuade North Korea from further deepening its support for Russia’s war on Ukraine. It marked their first in-person meeting since they met in Northern California last November.
Without mentioning Trump’s name, Xi appeared to signal his concern that the incoming president’s protectionist rhetoric on the campaign trail could send the U.S.-China relationship into another valley.
“China is ready to work with a new U.S. administration to maintain communication, expand cooperation and manage differences so as to strive for a steady transition of the China-U.S. relationship for the benefit of the two peoples,” Xi said through an interpreter.

Mr. Biden, meanwhile, spoke in broader brushstrokes about where the relationship has gone and reflected not just on the past four years, but on their long relationship.
“Over the past four years, China-U.S. relations have experienced ups and downs, but with the two of us at the helm, we have also engaged in fruitful dialogues and cooperation, and generally achieved stability,” he said.
Mr. Biden and Xi, with top aides surrounding them, gathered around a long rectangle of tables in an expansive conference room at Lima’s Defines Hotel and Conference Center.
There’s much uncertainty about what lies ahead in the U.S.-China relationship under Trump, who campaigned promising to levy 60% tariffs on Chinese imports.
Bobby Djavaheri, president of Los Angeles-based Yedi Houseware Appliances — which manufactures its products in China — told CBS News in an interview this week that such tariffs “would decimate our business, but not only our business. It would decimate all small businesses that rely on importing.”
Trump has also proposed revoking China’s Most Favored Nation trade status, phasing out all imports of essential goods from China and banning China from buying U.S. farmland.
Already, many American companies, including Nike and eyewear retailer Warby Parker, have been diversifying their sourcing away from China. Shoe brand Steve Madden says it plans to cut imports from China by as much as 45% next year.
White House national security adviser Jake Sullivan said Biden administration officials will advise the Trump team that managing the intense competition with Beijing will likely be the most significant foreign policy challenge they will face.
It’s a big moment for Mr. Biden as he wraps up more than 50 years in politics. He saw his relationship with Xi as among the most consequential on the international stage and put much effort into cultivating that relationship.
Mr. Biden and Xi first got to know each other on travels across the U.S. and China when both were vice presidents, interactions that both have said left a lasting impression.
“For over a decade, you and I have spent many hours together, both here and in China and in between. And I think we’ve spent a long time dealing with these issues,” Mr. Biden said Saturday.
But the last four years have presented a steady stream of difficult moments.
The FBI this week offered new details of a federal investigation into Chinese government efforts to hack into U.S. telecommunications networks. The initial findings have revealed a “broad and significant” cyberespionage campaign aimed at stealing information from Americans who work in government and politics.
U.S. intelligence officials also have assessed China has surged sales to Russia of machine tools, microelectronics and other technology that Moscow is using to produce missiles, tanks, aircraft and other weaponry for use in its war against Ukraine.
And tensions flared last year after Mr. Biden ordered the shooting down of a Chinese spy balloon that traversed the United States.
President-elect Donald Trump has selected Chris Wright, a campaign donor and fossil fuel executive, to serve as energy secretary in his upcoming, second administration.
CEO of Denver-based Liberty Energy, Wright is a vocal advocate of oil and gas development, including fracking, a key pillar of Trump’s quest to achieve U.S. “energy dominance” in the global market.
Trump also said in a statement Saturday that Wright will serve on the newly-created National Energy Council, which will be chaired by North Dakota Gov. Doug Burgum, Trump’s selection for secretary of the Interior.
Burgum will oversee a panel that crosses all executive branch agencies involved in energy permitting, production, generation, distribution, regulation and transportation, Trump said in a previous statement.
Wright has been one of the industry’s loudest voices against efforts to fight climate change and could give fossil fuels a boost, including quick action to end a year-long pause on natural gas export approvals by the Biden administration.
Wright also has criticized what he calls a “top-down” approach to climate by liberal and left-wing groups and said the climate movement around the world is “collapsing under its own weight.”
Consideration of Wright to head the administration’s energy department won support from influential conservatives, including oil and gas tycoon Harold Hamm.
Hamm, executive chairman of Oklahoma-based Continental Resources, a major shale oil company, is a longtime Trump supporter and adviser who played a key role on energy issues in Trump’s first term.
Hamm helped organize an event at Trump’s Mar-a-Lago resort in April where Trump reportedly asked industry leaders and lobbyists to donate $1 billion to Trump’s campaign, with the expectation that Trump would curtail environmental regulations if re-elected.
The Energy Department is responsible for advancing energy, environmental and nuclear security of the United States. The agency is in charge of maintaining the country’s nuclear weapons, oversees 17 national research laboratories and approves natural gas exports, as well as ensuring environmental cleanup of the nation’s nuclear weapons complex. It also promotes scientific and technological research.
Republican Sen. John Barrasso, who is expected to become chairman of the Senate Energy and Natural Resources Committee, said Trump promised bold choices for his Cabinet, and Wright’s nomination delivers.
“He’s s an energy innovator who laid the foundation for America’s fracking boom. After four years of America last energy policy, our country is desperate for a secretary (of energy) who understands how important American energy is to our economy and our national security,″ Barrasso said of Wright, adding: “Wright will help ensure America remains committed to an all-of-the-above energy policy that puts American families first.”
Thomas Pyle, president of the American Energy Alliance, a conservative group that supports fossil fuels, said Wright would be “an excellent choice” for Energy secretary. Pyle led Trump’s Energy Department’s transition team in 2016.
Liberty is a major energy industry service provider, with a focus on technology. Wright, who grew up in Colorado, earned undergraduate degree at MIT and did graduate work in electrical engineering at the University of California-Berkeley and MIT. In 1992, he founded Pinnacle Technologies, which helped launch commercial shale gas production through hydraulic fracturing, or fracking.
He later served as chairman of Stroud Energy, an early shale gas producer, before founding Liberty Resources in 2010.
