Nearly 40% of cancers can be prevented with 3 lifestyle changes, study finds

NEWYou can now listen to Fox News articles!

Nearly half of cancers could be avoided by cutting out three major risk factors, a new study has revealed.

Research published this week in Nature Medicine identified that nearly 40% of global cancer cases are linked to tobacco (15% of new cases), infections (10%) and alcohol consumption (3%).

Overall, 7.1 million cancer diagnoses in 2022 were linked to 30 modifiable risk factors, according to the study.

“The key here is that almost half of all cancers could be prevented by behavioral changes,” Dr. Marc Siegel, Fox News Digital senior medical analyst, told Fox News Digital.

Conducted by the World Health Organization and its International Agency for Research on Cancer (IARC), the study analyzed global cancer data across 185 countries, matching it with exposure data for the 30 risk factors.

Lung, stomach and cervical cancers accounted for nearly half of the cases that were linked to modifiable risks, with many linked to viruses and bacteria like the human papillomavirus (HPV), hepatitis B and C, and Helicobacter pylori (a common bacterium that infects the stomach lining).

“Preventable cancers of the cervix and throat are directly linked to the HPV virus and can be prevented by the HPV vaccine,” added Siegel, who was not involved in the study.

Lung cancer, throat and GI cancers, and several others were linked to cigarette smoking, and alcohol was associated with breast, liver, colon and throat cancer, the doctor noted.

“Environmental factors are also key, varying by geography — 45% of new cancers could be prevented in men, and 30% in women,” he said.

Study author Hanna Fink, from the Cancer Surveillance Branch at IARC/WHO, said the main message is that many cancers can be prevented.

“Almost four in 10 new cancer cases worldwide, which represent 7.1 million lives that don’t need to be changed by a cancer diagnosis, were linked to things we can change or modify through awareness and public-health action,” she told Fox News Digital.

“These things include tobacco smoking, infections, alcohol consumption, excess body weight, air pollution, ultraviolet radiation and others.”

Looking ahead, the researchers recommend that stronger prevention strategies targeting tobacco use, infections, unhealthy body weight and alcohol use could substantially reduce global cancer cases.

“The key here is that almost half of all cancers could be prevented by behavioral changes.”

“The study reinforces that cancer prevention works, and action is most effective at the population level,” Fink said. 

“Governments and communities play a crucial role by making healthy choices easier, for example, through higher tobacco and alcohol taxes, smoke-free policies, clear health warnings, safer workplaces, cleaner air, and affordable access to vaccination and screening. Individuals can support these by advocating for healthier environments and using available preventive services.”

Reducing the risk

The AIRC offers the following recommendations to minimize cancer risk.

  • Do not smoke, and if you do smoke, seek help to quit.
  • Keep alcohol intake as low as possible, as “there is no safe level of alcohol for cancer risk.”
  • Aim for a healthy body weight over time with a balanced diet and regular physical activity.
  • Move more and sit less, as even small amounts of daily movement help.
  • Take advantage of vaccines, especially the HPV vaccination for young people and the hepatitis B vaccination.

“As a family physician, I try to help my patients understand how important their daily habits are in lowering their future cancer risk,” said Dr. Chris Scuderi, a cancer survivor and Florida-based family physician.

The doctor’s key prevention targets include daily exercise, consistent and restorative sleep, a Mediterranean-style diet, regular doctor’s visits and sufficient rest.

“Small daily wins add up to make a powerful difference over time,” added Scuderi, who also was not involved in the research. “It’s also essential to stay on top of your routine screenings, which your family physician can help you with.”

Potential limitations

The study did have some limitations. The researchers often used data from around 2012 due to the long delay between exposure and cancer, which means the data may not reflect the most recent behaviors or environments.

“This is a necessary simplification, because in reality, latency can be longer or shorter depending on the cancer and the exposure,” Fink noted.

Siegel pointed out that cancer types vary by geographic region — for example, stomach cancer is more prominent in Asia — and the relationships between risk factors and cancer prevalence can differ between countries, populations and time periods.

“We rely on the best available data on how common each risk factor is in different countries and how strongly it is linked to cancer, but these data are not perfect and are weaker in some low- and middle-income countries,” Fink said.

Finally, the study only looked at 30 risk factors with the strongest evidence and global data.

“Our estimate of ‘almost 40% of cancers are preventable’ is very likely conservative,” the researcher added. “Some other suspected causes, such as certain aspects of diet, could not be included because the science or the data are not yet robust enough at a global level.”

Dementia risk signals could lie in simple blood pressure readings, researchers say

Dementia risk signals could lie in simple blood pressure readings, researchers say

NEWYou can now listen to Fox News articles!

Simple measurements taken during routine blood pressure checks could predict dementia risk years before symptoms appear.

That’s according to new research presented this week at the American College of Cardiology’s Annual Scientific Session in Louisiana.

The findings draw on two studies led by researchers at Georgetown University, which suggest that monitoring how blood vessels age and stiffen over time can provide a window into future cognitive health.

LURKING DEMENTIA RISK EXPOSED BY BREAKTHROUGH TEST 25 YEARS BEFORE SYMPTOMS

Data shows rates of dementia and aging-related cognitive decline are expected to increase as populations age, and half of U.S. adults have high blood pressure (hypertension).

Scientists believe that efforts to better address hypertension, a key contributor to heart disease and a risk factor for dementia, could affect both cardiac and brain health.

“Blood pressure management isn’t just about preventing heart attacks and strokes; it may also be one of the most actionable strategies for preserving cognitive health,” Dr. Newton Nyirenda, the study’s lead author and an epidemiologist at Georgetown University in Washington, said in a press release.

The research focused on two metrics, the pulse pressure-heart rate index and estimated pulse wave velocity. Both were calculated using data collected during standard doctor visits, such as heart rate, age and blood pressure.

“Blood pressure management isn’t just about preventing heart attacks and strokes; it may also be one of the most actionable strategies for preserving cognitive health.”

Researchers examined five years of data patterns for more than 8,500 people in the SPRINT trial, a large study of adults 50 years and older with hypertension. In the follow-up, 323 of the participants developed probable dementia.

In one study, the team found the pulse pressure-heart rate index was a strong independent predictor of dementia risk in adults over 50. For participants under 65, every one-unit increase was associated with a 76% higher risk of developing dementia.

The second study found that adults with consistently elevated or rapidly increasing pulse wave velocity were more likely to develop dementia than those with stable velocity, even after accounting for factors like smoking, gender and cardiovascular history.

“Our findings suggest that vascular aging patterns may provide meaningful insight into future dementia risk,” said Nyirenda. “This reinforces the idea that managing vascular health earlier in life may influence long-term brain health.”

The team emphasized that clinicians should tailor risk assessments and treatment strategies to the individual.

“You don’t want to wait until a patient starts manifesting cognitive decline before you act,” said senior study author Sula Mazimba, an associate professor at the University of Virginia.

Researchers noted the study could not establish causation. Other limitations included the fact that participants already had hypertension and elevated cardiovascular risk, meaning the findings may not apply to people without those conditions.

‘Gas station heroin’ banned in another state amid nationwide crackdowns

NEWYou can now listen to Fox News articles!

A dangerous substance dubbed “gas station heroin” continues to alarm medical professionals, with more states making moves to restrict or ban tianeptine.

Fourteen states have officially classified the tricyclic antidepressant as a Schedule I controlled substance.

Connecticut is the latest state to crack down, officially banning the sale and use of the substance starting on Wednesday.

HEALTH OFFICIALS WARN OF DANGEROUS SUBSTANCE AVAILABLE IN STORES ACROSS THE NATION

Tianeptine, which can produce euphoria in higher doses, can be more potent than morphine and addictive opioids, according to the U.S. Food and Drug Administration.

Some countries have taken steps to restrict how tianeptine is prescribed or dispensed, and have even revised the labels to warn people of its potential addictive qualities.

Misuse of tianeptine can cause severe adverse health effects, including respiratory depression, severe sedation and death, according to the Drug Enforcement Administration.

Some companies market the drug as an aid for pain, anxiety and depression, or as a means of improving mental alertness in a pill, powder, salt or liquid form.

The products are typically sold at convenience stores, gas stations, vape shops and online retailers, and go by names like Tianaa, ZaZa, Neptune’s Fix, Pegasus and TD Red.

Connecticut Lt. Gov. Susan Bysiewicz said in a press release that the schedule change is a necessary step to combat addiction.

“With false marketing that led consumers to believe these are safe products, and with candy-like flavor options, these substances posed a clear threat to those battling substance-use disorder and our youngest residents,” she added.

The Nutmeg State also added Mitragyna speciosa (kratom), 7-hydroxymitragynine, Bromazolam, Flubromazolam, Nitazenes and Phenibut to the schedule classification.

Earlier this month, FDA Commissioner Martin Makary penned a letter sounding the alarm on what he called a “dangerous and growing health trend.”

“I am very concerned,” Makary wrote. “I want the public to be especially aware of this dangerous product and the serious and continuing risk it poses to America’s youth.”

New York-based Robert Schwaner, M.D., vice chair of system clinical affairs at Stony Brook Emergency Medicine, told Fox News Digital that the FDA has never approved tianeptine as a dietary supplement.

“As with heroin and other opioids, significant mu-opioid receptor stimulation ultimately results in a loss of respiratory drive and subsequent cardiac arrest.” (Dekalb County Sheriff’s Office)

“The euphoria at low doses is primarily due to increased serotonergic activity from its serotonin reuptake effects. With increasing doses, the mu-opioid receptor stimulation may become lethal,” said Schwaner. “As with heroin and other opioids, significant mu-opioid receptor stimulation ultimately results in a loss of respiratory drive and subsequent cardiac arrest.”

Schwaner said he believes the substance requires national regulation due to its addictive qualities.

“Acting at the same receptor as opioids, tianeptine has the potential for an individual to develop tolerance, subsequent dependence and withdrawal from its use,” he cautioned.
