Cancer can strike at any age, often without symptoms. For many cancers, routine screening remains the best way to detect the disease early and reduce the risk of death.

For lung cancer, screening guidelines can vary, as the disease doesn’t always show obvious signals and can occur in both smokers and never-smokers.

Daniel J. Boffa, M.D., chair of the American College of Surgeons Commission on Cancer and a thoracic surgeon at Yale University, noted that lung cancer screening is "one of the most powerful ways" to boost survival.

"It reduces the chance of people dying of lung cancer by 20%," he told Fox News Digital.

The share of Americans who are eligible for screening but don’t comply translates to "tens of thousands of preventable deaths every year," according to Boffa.

"I'm hoping that within four or five years, a screening CT scan will only be confirmatory after they have a positive blood test done at your doctor's office," he added.

That approach could make screening easier and potentially help detect more lung cancers, according to the doctor.

Potential symptoms

In a recent interview with Fox News Digital, Lary Robinson, M.D., an oncologist at Moffitt Cancer Center in Tampa, Florida, noted that in most cases, early-stage lung cancer will not come with any symptoms.

In those who do have symptoms, however, the most common are related to the lungs, including a persistent cough, shortness of breath or coughing up blood.

Unexplained weight loss can result from any form of cancer, according to the oncologist. Neurological symptoms, like persistent headaches, may also warrant seeing a doctor.

Current guidelines

Current lung cancer screening guidelines recommend an annual low-dose CT scan for people between the ages of 50 and 80 who currently smoke or have a history of smoking or have at least a 20 pack-year history of smoking, according to the American Cancer Society (ACS).

Before making the decision to get screened, individuals should speak with their healthcare providers about the purpose of the screening and how it’s done, as well as the benefits, limits and possible harms, ACS advised.

Those who still smoke should be counseled about quitting and offered interventions and resources to help.

Individuals with serious health problems that will "likely limit" their lifespan should not be screened, according to ACS, as well as those who won’t be able to get treatment if lung cancer is detected.

NEVER SMOKED A CIGARETTE? YOU COULD STILL BE AT HIGHER RISK FOR LUNG CANCER

Although one out of seven lung cancers will affect someone who has never smoked, there is currently not a set screening guideline for never-smokers.

Finding individuals who would benefit from screening is an "intense area of research," according to Boffa. For now, people with a direct family history of lung cancer without smoking should consider annual screenings, as should higher-risk demographics like Asian women.

"I would anticipate that in the next year or two, we will have better guidance for people who are at risk for lung cancer, but never smoked," Boffa predicted.

What to expect

Boffa noted that advances in lung cancer treatment have improved survival, even at advanced stages, so screening should not be viewed as a pathway to a terminal diagnosis.

"People are really reluctant to be diagnosed with lung cancer because it does carry a stigma," Boffa said. "For years, there was a reputation that it was a terminal diagnosis. It's just been amazing what research has done for lung cancer."

Most screenings detect a lung nodule or other abnormality, which is more often an infection, scar or inflammation than a tumor, he said.

In about one-third of patients, lung cancer screenings also detect unrelated health issues, including the hardening of heart arteries or a nodule in another part of the body.

"The reality is over 99% of nodules are actually benign," Boffa said. "And so, you need to have a conversation about what you are going to do with that information."

"I think having that conversation ahead of time is really important so that expectations are set – it's not uncommon to find something. Most of the time, it's not something that's going to affect how long you live."

The doctor noted that the CT scan only takes a couple of minutes to perform and does not take place in an enclosed space like an MRI.

"People who get claustrophobic usually don't have a hard time with lung cancer screening," Boffa said. "And it usually takes a few days to get a report back."

For those who are over 50 with a history of smoking, Boffa reiterated that getting screened is "one of the most powerful things you can do to reduce your chances of having your life shortened by lung cancer."

Antibody patterns in the blood may help doctors identify people at risk so they can be treated earlier, research shows

Patterns of antibodies in people’s blood could predict the onset of inflammatory bowel disease (IBD) a decade before diagnosis, according to research that raises hopes for catching the condition early.

Crohn’s disease and ulcerative colitis, the two main forms of IBD, are typically treated only after symptoms appear, when the gut has already been damaged. But scientists found that the immune system sends warning signals up to a decade before diagnosis, paving the way for potentially earlier detection and even prevention.

• A Pew Research survey found only 47% of middle-income earners could save money in the past year.
• Lower-income earners are also having a hard time saving and affording necessities.
• Inflation moving in the wrong direction doesn't help the affordability situation.

America's middle earners are feeling the squeeze.

A new analysis from the Pew Research Center examines how Americans' finances are faring, an especially salient topic in a midterm season where affordability is very much on the ballot.

America's middle earners — those who make between $50,700 and $152,000 after adjusting for their family sizes and the cost of living in their areas — increasingly don't have enough saved for an emergency. Just over half of middle-income Americans say they don't have rainy-day funds that would cover expenses for three months in the event of an emergency.

Meanwhile, 47% of middle-income earners — and a measly 24% of lower-income earners — reported being able to save money in the past year. Across all income tiers, the majority of respondents said they had cut back spending on extras like eating out or streaming services.

Those dwindling emergency funds and sacrifices might be due to rising costs, which often take a particularly large bite out of lower-earners' wallets.

It could be getting worse; inflation is moving in the wrong direction. In September, the consumer price index inflation rate rose from 3.4% to 3.7%, just above the 3.6% forecast. Plus, inflation-adjusted wages have been falling for six months.

Today's economy is still more difficult for those at the bottom of the earnings ladder. Fifty-one percent of lower-income respondents said they can pay all of their bills in full in the 2026 survey, down from 56% in 2020. For middle-income respondents, the share dropped from 81% in 2020 to 78% in 2026, while the share of upper-income respondents held steady at 93%.

Pew also found 71% of lower-income US adults struggled with at least one kind of basic necessity, like affording medical care or paying their rent or mortgage, in the past year, compared with 39% of middle-income and 13% of upper-income Americans.

But the latest survey marks another sign that middle-income earners are increasingly aligning with their lower-earning peers, a dour sign for the health of the middle class. A separate report from the Urban Institute found that, even as lower-income renters were the most likely to report issues paying the rent, middle-income renters were increasingly likely to report struggling to pay.

Similarly, middle-income earners' consumer sentiment has switched from mirroring their higher-earning peers to more closely aligning with lower earners — another sign that the middle class is falling on harder economic times.

"Working people are living on the edge, working longer and harder than ever for less money," said AFL-CIO President Liz Shuler. "They're angry every time they fill the tank. They're terrified of what their heating bills will look like this winter."

The Spanish Socialist Workers’ Party (PSOE) leads the projected vote share with 34%, while the People’s Party (PP) stands at 22.2%, according to the October barometer from the Center for Sociological Research (CIS), conducted between October 1 and 6 with 5,025 interviews.

Marches in Spain Honor Maricarmen, the Evicted Woman Who Died Amid the Housing Crisis

The poll, carried out following the eviction of Maricarmen Abascal and amidst the ongoing debate over housing in Spain, gives the Socialists a projected 34% of the vote—three points higher than in September. The People’s Party dropped 3.3 points to 22.2%, widening the gap between the two parties to 11.8 points as the pre-campaign period for the November 29 general election begins.

Meanwhile, the ultra-conservative party Vox has solidified its position as the third-largest political force with 17.1% support, up half a point from the previous barometer. For its part, Frente Amplio reaches 6.1% and Podemos obtains 3.1% of the estimated vote.

The survey was published following the eviction of Maricarmen Abascal on September 23 and the elderly woman’s death on October 7. The case sparked protests and encampments advocating for the right to housing in several Spanish cities.

Housing remains the primary concern for Spaniards, cited by 55.7% of respondents. It is followed by immigration (20.9%) and the economic crisis (20.3%).

The text reads, “82.3% of Spaniards agree that priority must be given to “the right to housing as a constitutional right.” This and other data are included in the October barometer”

Additionally, 82.3% of those surveyed believe that the right to housing should be prioritized as a constitutional right. An earlier CIS barometer, published on October 8, already showed that 91% of respondents called for more public housing and 76% supported state intervention in the sector.

88.9% of those surveyed stated they had heard about Maricarmen’s case. Among those aware of the eviction, 57.1% maintained that the protection of vulnerable people is the most important aspect.

The government introduced two housing decree-laws, but they were rejected in Congress by conservative parties. That parliamentary defeat precipitated the call for early elections announced by Prime Minister Pedro Sánchez on October 5.

Mobilizations regarding access to housing will continue with a general housing strike scheduled for November 11, amidst a climate where the housing crisis sits at the center of the political and electoral agenda.

The barometer also reflects heightened concern regarding the war in the Middle East: 72.6% of respondents described themselves as “very” or “quite” concerned—an increase of 2.5 points compared to the previous survey. The Russian invasion of Ukraine is a source of concern for 68.4%, while 73.6% are worried about climate change.
