Lung screening in Deerfield Beach, FL is primarily recommended for adults between 50 and 80 who have at least a 20 pack-year smoking history and either still smoke or quit within the past 15 years. Adults who meet all three conditions may benefit from yearly screening with low-dose CT.
At Life Imaging, we also hear from people whose concerns extend beyond cigarette smoking. Some spent years around indoor tobacco smoke. Others worked around asbestos, construction dust, vehicle exhaust, or chemical fumes. These exposures belong in a lung health discussion, but they do not automatically qualify someone for annual LDCT under current national guidelines.
Our Deerfield Beach screening is intended for stable adults who are not experiencing symptoms that need immediate evaluation. If you have a persistent cough, chest pain, coughing up blood, or worsening shortness of breath, contact a healthcare provider before booking a routine screening appointment.

Who Meets the Recommended Lung Screening Criteria?
The Centers for Disease Control and Prevention recommends annual low-dose CT lung screening when a person meets all three of the following requirements:
Age 50 through 80
Research supporting LDCT screening focuses on adults in this age group who also have a substantial smoking history. Age by itself does not determine eligibility.
A smoking history of at least 20 pack-years
This measurement combines how much a person smoked with the number of years they smoked — a more useful estimate of cumulative cigarette exposure than simply asking whether someone has ever smoked.
Current smoking or quitting within the past 15 years
Former smokers can remain at elevated risk after their last cigarette. Screening may continue for up to 15 years after quitting, provided the person still meets the other criteria.
Being eligible does not mean screening should continue regardless of overall health. The possible value becomes limited if a serious illness prevents a person from receiving treatment should lung cancer be found. Screening should involve a discussion about the benefits, radiation exposure, possible false-positive findings, and what the patient would choose to do if the scan showed something suspicious.
How Do You Calculate Pack-Years?
Multiply the average number of cigarette packs smoked each day by the total number of years smoked. For example:
- One pack a day for 20 years equals 20 pack-years
- Two packs a day for 10 years also equals 20 pack-years
- Half a pack a day for 40 years equals 20 pack-years
- One and a half packs a day for 20 years equals 30 pack-years
Real smoking histories are often less tidy. A person may have smoked heavily in their twenties, cut back later, stopped for several years, and eventually started again. Break the history into separate periods:
- Write down the years you smoked during each period
- Estimate how many packs you smoked per day at that time
- Calculate the pack-years for each period
- Add the results together
Cigar, pipe, vaping, and secondhand smoke exposure cannot be converted into cigarette pack-years with the same formula. Tell your physician about them separately.
Should Former Smokers Continue Annual Lung Screening?
A former smoker may remain eligible if fewer than 15 years have passed since quitting and the age and pack-year requirements are still met. Quitting lowers lung cancer risk, but the change occurs gradually — this is why someone who stopped smoking several years ago may still benefit from annual LDCT. The CDC explains that quitting smoking reduces cancer risk, with benefits that continue to grow over time.
Screening is generally stopped when a person:
- Reaches 81 years old
- Has not smoked for at least 15 years
- Develops a health condition that substantially limits life expectancy
- Becomes unable or unwilling to undergo treatment if lung cancer is found
Keep a record of when you quit. If you stopped and restarted more than once, tell your physician so the full timeline can be considered. Annual screening does not take the place of smoking cessation — if you currently smoke, quitting remains the most effective step you can take to reduce your future lung cancer risk.
What Other Risk Factors Should You Discuss With a Physician?
Not everyone worried about lung cancer fits the standard smoking criteria. Other exposures may influence risk, but none should be treated as an automatic reason for yearly CT.
Secondhand Smoke
Years of living or working around cigarette smoke can affect lung health. Describe where the exposure occurred, how frequently it happened, and how long it continued. Current annual screening criteria do not include secondhand smoke alone — a physician can consider it alongside age, personal smoking, family history, and other exposures.
Occupational Exposure
People living in Deerfield Beach today may have spent much of their working lives elsewhere. Construction, manufacturing, automotive repair, shipyard work, mining, maintenance, and certain industrial jobs may involve hazardous airborne substances. The National Cancer Institute lists asbestos, arsenic, chromium, nickel, beryllium, cadmium, tar, and soot among occupational lung cancer risks.
Tell your physician:
- What substance you worked around
- How many years the exposure lasted
- Whether protective equipment was used
- Whether the exposure happened indoors
- Whether you also smoked
- Whether your employer provided health monitoring
Family History
A parent, sibling, or child with lung cancer may affect personal risk. The age at which your relative was diagnosed and whether they smoked can add useful context. Family history alone does not currently establish eligibility for annual LDCT, but it should still be part of the conversation.
Radon Exposure
Radon is a radioactive gas that can collect inside homes and buildings. Long-term exposure is associated with lung cancer, especially for people who smoke. A home radon test shows the level inside the building, but not whether disease is present. Bring any known exposure into your risk discussion with a physician.
The next step might be LDCT, pulmonary function testing, occupational health review, or another evaluation.
When Should You Seek Medical Evaluation Instead?
Lung screening is meant for people who do not have symptoms suggesting an active lung problem. If symptoms are already present, a physician may need to order diagnostic imaging. Seek medical care for:
Coughing up blood
Even a small amount should be evaluated. Do not wait for a routine screening appointment.
A cough that persists or changes
A cough that lasts, becomes more frequent, or feels different from your usual pattern deserves attention.
Increasing shortness of breath
Sudden breathing difficulty may require emergency care. A healthcare provider should also review a gradual decline in breathing.
New or unexplained chest pain
Chest pain can come from the lungs, heart, muscles, or digestive system. Severe or sudden pain requires prompt care.
Unintentional weight loss
Weight loss without an obvious cause should be evaluated, particularly when accompanied by cough, appetite loss, or fatigue.
Repeated pneumonia or respiratory infections
Infections that keep returning, especially in the same lung region, may require diagnostic imaging.
A low-dose screening CT is not designed to investigate these symptoms. Your physician may instead select a standard diagnostic CT, chest X-ray, blood work, or pulmonary testing.
How Is Low-Dose CT Different From a Chest X-Ray?
A chest X-ray produces a single flat image of the chest structures — bones, blood vessels, and lung tissue overlap. Low-dose CT produces multiple cross-sectional images, letting a radiologist move through the chest section by section and see smaller lung changes that may be hidden on an X-ray.
The National Lung Screening Trial found that screening high-risk adults with low-dose CT reduced lung cancer deaths compared with screening by chest X-ray. The finding applies to people with a substantial risk of lung cancer — it does not mean LDCT should become an annual test for every adult. Screening LDCT also differs from diagnostic chest CT, which may use contrast, a different radiation dose, or a protocol selected to investigate symptoms or a known condition.
What Can a Lung Screening Scan Show?
Low-dose CT may reveal small lung nodules before they cause symptoms. A lung nodule is a spot within the lung that looks different from the surrounding tissue. Most nodules are not cancer — some remain after an infection, while others arise from scar tissue, inflammation, or other benign processes. The scan may also show:
- Emphysema-related changes
- Areas of lung scarring
- Signs of an older infection
- Pleural thickening or fluid
- Enlarged lymph nodes
- Calcified areas
- Other structural changes within the chest
- Findings outside the lungs that appear within the scan area
The radiologist considers a nodule’s size, shape, density, edges, and location. Comparing the scan with older images can show whether the area has remained stable or changed. LDCT cannot confirm lung cancer by itself — further evaluation may involve a diagnostic CT scan, a PET scan, a pulmonologist consultation, or a biopsy.
What Are the Possible Downsides of Screening?
Screening high-risk adults can identify lung cancer earlier, but patients should understand what may happen after the scan.
A Result Can Be False-Positive
The scan may show a suspicious area that later turns out not to be cancer. Many findings are resolved through repeat imaging, while some require more involved testing.
The Scan May Find Something Unexpected
CT captures more than the lungs. A thyroid, vascular, kidney, or other incidental finding may appear. Some need follow-up even though they are unrelated to lung cancer.
LDCT Still Uses Radiation
The radiation dose is lower than that of a standard diagnostic chest CT. Repeating the screening every year still creates cumulative exposure.
Screening Can Lead to Overdiagnosis
Some cancers discovered through screening may never have caused symptoms during the person’s lifetime. Finding them can lead to treatment that might not otherwise have been needed.
A Normal Result Is Not a Lifetime Guarantee
Lung cancer can develop between screenings. A normal report should never be used to dismiss future symptoms.
These limits do not remove the benefit for eligible patients. They explain why annual screening should begin with an informed decision and continue only as long as it remains appropriate.
What Happens During Lung Screening in Deerfield Beach?
Our lung screening in Deerfield Beach uses low-dose CT and does not require sedation. You lie on the scanner table with your arms positioned as directed. The table moves through the scanner’s open center while images are taken. Our technologist may ask you to hold your breath for a few seconds. Tell us before the scan if you:
- May be pregnant
- Recently completed chest imaging
- Have a lung nodule already being monitored
- Have undergone lung surgery
- Are currently receiving cancer care
- Have developed new respiratory symptoms
- Have difficulty lying flat or holding your breath
The scan itself is brief. Once the images have been reviewed, you receive a written report to share with your physician.
What Should You Do With the Results?
A reassuring report may recommend another low-dose scan in one year if you remain eligible. If a nodule or another change appears, the report may recommend earlier follow-up — that does not mean cancer has been diagnosed. The next step depends on the size, appearance, and stability of the finding.
Follow-up may include:
- Comparing the scan with earlier images
- Repeating low-dose CT after a stated interval
- Completing a diagnostic chest CT
- Consulting a pulmonologist
- Undergoing pulmonary function testing
- Having PET imaging
- Considering biopsy when appropriate
Keep each report. A series of scans can show whether a nodule is stable, growing, or changing in appearance. Follow the recommended timeline rather than waiting indefinitely or scheduling repeated CT scans without physician guidance.
How Does Our Deerfield Beach Location Serve the Area?
Our Deerfield Beach center is located at 1981 W Hillsboro Boulevard. We see patients from Deerfield Beach and nearby communities, including Boca Raton, Pompano Beach, Coconut Creek, Lighthouse Point, and Hillsboro Beach.
A person’s current ZIP code tells only part of the health story. Many South Florida residents have lived or worked elsewhere, where they may have encountered cigarette smoke, industrial dust, asbestos, diesel exhaust, or other airborne substances. When reviewing your lung risk, think beyond your current home:
- Where did you spend most of your working years?
- Did anyone smoke inside your childhood or adult home?
- Were you given respiratory protection at work?
- Have you lived in a building with elevated radon?
- Did you serve in the military or work at an industrial site?
- Have you had previous chest imaging or serious lung infections?
Bring the complete history to your physician. The decision should reflect your lifetime exposure, not only your years in Deerfield Beach.
