Protecting your lung health in Florida starts with understanding your personal risks. For some adults with a significant smoking history, annual low-dose CT screening can help identify lung cancer at an earlier stage, before symptoms begin. For others, routine screening may offer little benefit and could lead to unnecessary follow-up testing.
Age and smoking history are the two main factors used to determine eligibility. Environmental and occupational exposures may also deserve discussion with your physician, but they do not automatically mean that a screening scan is recommended.
Life Imaging offers low-dose CT lung screening at our Deerfield Beach, Jupiter, Coral Gables, and Orlando centers. The right location depends on where you live in Florida and current appointment availability.
If you are unsure whether lung screening fits your history, contact Life Imaging. We can explain the scan and help you prepare for a conversation with your healthcare provider.
Who Should Consider Lung Cancer Screening in Florida?
Current federal guidance recommends annual low-dose CT lung cancer screening for adults who meet all three of these requirements:
- You are between 50 and 80 years old. Screening is intended for adults in this age range who are at increased risk but do not currently have symptoms of lung cancer.
- You have at least a 20 pack-year smoking history. Pack-years account for both the number of packs smoked and the number of years a person smoked.
- You currently smoke or quit within the past 15 years. Risk declines after someone stops smoking, but it does not disappear immediately.
The Centers for Disease Control and Prevention identifies low-dose CT as the recommended lung cancer screening test for adults who meet these criteria.
Meeting the criteria does not mean you are required to undergo screening. It means the potential benefits are worth discussing with your physician. Your overall health, previous scans, willingness to complete follow-up, and ability to undergo treatment if cancer is found also matter.
How Do You Calculate Your Pack-Year Smoking History?
A pack-year is a practical way to measure lifetime cigarette exposure. One pack-year equals smoking an average of one pack of cigarettes each day for one year.
The calculation is:
Average packs smoked each day × number of years smoked = pack-years
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.
Smoking habits are not always consistent. Perhaps you smoked heavily during one part of your life and less during another. Estimate each period separately, then add the results together.
If you are unsure about your total, write down when you started, when you stopped, and how much you smoked during different periods. Your physician or our scheduling team can help you organize the information.
Why Is Smoking History So Important?
Cigarette smoking is the leading risk factor for lung cancer. Tobacco smoke repeatedly exposes the lung tissue to chemicals that can damage cells over time.
The risk tends to increase with both the amount smoked and the number of years a person smoked. Someone who stopped several years ago may still carry an elevated risk, which is why current guidelines include former smokers who quit within the past 15 years.
A person who smoked for many years may feel completely well. That is precisely when screening is intended to take place. Lung cancer can develop before it produces noticeable symptoms, and low-dose CT may identify a suspicious area when it is still small.
Screening does not undo the effects of smoking, and it is not a substitute for quitting. If you currently smoke, ask your healthcare provider about counseling, medication, and other support that may make quitting more manageable.
Do Florida’s Environment and Climate Affect Lung Health?
Living in Florida does not automatically mean you need a lung CT scan. Still, the state’s climate and built environment can introduce concerns worth addressing in other ways.
Indoor Dampness and Mold
Florida’s heat and humidity can make it easier for moisture to collect in homes and buildings. Roof leaks, plumbing problems, flooding, and poorly controlled indoor humidity can create conditions for mold growth.
Mold exposure can irritate the airways and may worsen coughing, wheezing, or asthma in sensitive people. A CT screening scan is not the first step for suspected mold exposure. The source of moisture should be corrected, and a healthcare professional should evaluate persistent respiratory symptoms.
Radon
Radon is a naturally occurring radioactive gas that can enter buildings through the ground. It cannot be seen or smelled. Long-term exposure increases the risk of lung cancer, particularly for people who smoke or previously smoked.
The only way to know the radon level in a home is to test it. The U.S. Environmental Protection Agency recommends that all homes be tested. A radon test evaluates the building, while a low-dose CT scan evaluates the lungs. One cannot replace the other.
Outdoor Air and Smoke
Wildfire smoke, vehicle exhaust, dust, and periods of poor air quality can irritate the lungs. People with asthma, chronic obstructive pulmonary disease, or other respiratory conditions may notice symptoms sooner.
Check local air-quality reports when smoke or pollution is present. If poor air repeatedly causes wheezing, breathlessness, or chest tightness, speak with a physician rather than relying on preventive CT screening.
Occupational Exposure
Construction, shipyard, manufacturing, automotive, agricultural, and restoration work may involve dust, asbestos, silica, diesel exhaust, chemicals, or other materials that affect respiratory health.
A work history can be important, especially when occupational exposure overlaps with smoking. Tell your physician what substances you handled, how long the exposure lasted, and whether respiratory protection was used.
What Does a Low-Dose CT Lung Screening Show?
Low-dose CT creates cross-sectional images of the lungs using less radiation than a standard diagnostic chest CT. It may reveal small nodules and other visible changes before they cause symptoms.
A lung nodule is a small spot in the lung. Most nodules found through screening are not cancer. They may come from an old infection, inflammation, scar tissue, or another harmless process.
The radiologist considers several details:
- The nodule’s size, shape, and location
- Whether it appears solid or partly solid
- Whether more than one nodule is present
- Whether it has changed since an earlier scan
- Whether another lung or chest abnormality is visible
A small nodule may only need another scan after a recommended interval. A larger or changing area may require diagnostic imaging or specialist evaluation.
The first scan often serves as a baseline. If screening continues, future images can be compared with it to see whether a finding has remained stable.
What Can Lung Screening Not Tell You?
A lung screening scan has a specific purpose. It does not provide a complete evaluation of every respiratory condition, and it cannot guarantee that lung cancer is absent.
Low-dose CT cannot:
- Confirm that every lung nodule is harmless or cancerous
- Replace a biopsy when tissue diagnosis is necessary
- Measure lung function
- Diagnose asthma based on images alone
- Explain every cough or episode of breathlessness
- Replace medical evaluation of active symptoms
- Prevent future lung cancer
Some cancers can be too small to see, hidden by nearby structures, or develop between annual examinations. A normal scan should not cause you to ignore a new symptom or continue smoking under the assumption that your lungs are clear.
What Are the Possible Drawbacks of Lung Screening?
Screening can help people at high risk, but it also carries potential harms. Understanding them beforehand makes it easier to decide whether the scan is right for you.
False-Positive Results
A scan may identify a nodule that looks concerning but turns out not to be cancer. This is known as a false-positive result. It may lead to additional imaging and, less commonly, a biopsy or procedure.
Incidental Findings
The scan covers portions of the chest outside the lungs. It may reveal an unexpected change involving another structure. Some incidental findings require follow-up even though they are unrelated to lung cancer.
Radiation Exposure
Low-dose CT uses a small amount of ionizing radiation. The exposure from one scan is limited, but screening is performed annually for eligible patients. The cumulative exposure should be considered.
Overdiagnosis
Screening can occasionally find a cancer that might never have caused symptoms during the person’s lifetime. It is not always possible to know in advance which cancer will grow aggressively.
These concerns are why lung screening is recommended for people at higher risk rather than every adult.
When Should Lung Screening Stop?
Under current federal recommendations, annual screening should stop when a person:
- Reaches age 81
- Has not smoked for at least 15 years
- Develops a medical condition that substantially limits life expectancy
- Would be unable or unwilling to undergo curative treatment if cancer were found
Screening may also pause while a specific finding is being evaluated. In that situation, the next scan may be considered diagnostic follow-up rather than routine annual screening.
Do not assume that you need a scan every year for the rest of your life. Review your eligibility with your healthcare provider as your age, smoking history, and overall health change.
Should People Who Never Smoked Get Lung Screening?
Routine low-dose CT lung cancer screening is not generally recommended for people who never smoked. Even when another risk factor is present, there may not be enough evidence that annual scanning provides more benefit than harm.
People who never smoked can still develop lung cancer. Radon, secondhand smoke, family history, previous radiation treatment, and occupational exposure may influence risk. However, those factors do not automatically place someone within the standard federal screening group.
If you have a strong family history or substantial environmental exposure, discuss it with your physician. The decision should be individualized rather than based on fear alone.
When Do Lung Symptoms Require Medical Care?
Screening is meant for people without symptoms. Once a symptom appears, the goal changes from screening to diagnosis.
Contact a healthcare provider if you experience:
- A new cough that does not improve
- Coughing up blood
- Unexplained shortness of breath
- Chest pain that worsens with breathing or coughing
- Persistent hoarseness
- Repeated lung infections
- Unexplained weight loss
- A noticeable decline in stamina
These symptoms have many possible causes, and most do not automatically mean lung cancer. They still deserve proper evaluation.
Call 911 for severe breathing difficulty, blue or gray lips, confusion, fainting, or sudden chest pain. Do not wait for a preventive imaging appointment.

What Happens During a Lung Screening?
Low-dose CT screening is quick and does not normally require contrast dye, needles, or sedation. You will lie on the CT table while it moves through the scanner’s open center.
The technologist may ask you to raise your arms and hold your breath for several seconds. Holding still helps reduce motion and produces clearer images. The scan itself generally takes only a few minutes.
You can usually return to your normal activities immediately afterward. A radiologist reviews the images and prepares a report. The report may recommend annual screening, a shorter follow-up interval, comparison with earlier imaging, or another type of evaluation.
Bring the results to your primary care physician. If something needs closer review, your doctor can help coordinate the next step.
How Should You Prepare for Lung Screening?
Preparation is usually minimal:
- Wear comfortable clothing without unnecessary metal.
- Leave necklaces and other jewelry at home when possible.
- Bring information about earlier chest imaging.
- Write down your smoking history, including how much you smoked and for how many years.
- Tell the team if you are pregnant or could be pregnant.
- Mention any current respiratory symptoms before the scan.
- Follow the instructions provided when your appointment is scheduled.
Do not stop prescription medications unless a qualified healthcare provider specifically tells you to do so.

Frequently Asked Questions
At what age should lung cancer screening begin?
Current federal recommendations begin at age 50 for people who also have at least a 20 pack-year smoking history and currently smoke or quit within the past 15 years. Age alone does not make someone eligible.
Can I get screened if I stopped smoking more than 15 years ago?
You fall outside the standard federal criteria once you have not smoked for 15 years. Other health risks may still deserve discussion with your physician, but routine annual low-dose CT screening may not be recommended.
Is a chest X-ray enough for lung cancer screening?
No. Chest X-rays are not the recommended screening test for people at high risk of lung cancer. Low-dose CT can show smaller nodules that may not appear clearly on a standard X-ray.
Does finding a lung nodule mean I have cancer?
No. Most lung nodules are not cancer. Their meaning depends on size, shape, appearance, growth, and personal risk factors. Some only require another scan after a recommended interval.
Does insurance cover annual lung screening?
Many insurance plans and Medicare cover recommended low-dose CT screening for eligible patients, although coverage rules vary. Confirm benefits, referral requirements, and possible follow-up costs directly with your insurer before scheduling.
Can lung screening replace quitting smoking?
No. Screening may help find lung cancer earlier, but it does not prevent cancer or repair smoking-related damage. Quitting remains one of the most meaningful steps a person can take to reduce future lung and cardiovascular risk.
Is It Time to Consider Lung Screening?
For adults between 50 and 80 with at least a 20 pack-year smoking history who currently smoke or quit within the past 15 years, annual low-dose CT screening may be appropriate. For people outside that group, the balance between benefit and possible harm is less clear.
Start by calculating your pack-year history and gathering information about previous chest scans. Then discuss your health, smoking history, and readiness for follow-up with your physician.
Life Imaging offers lung screening at our Deerfield Beach, Jupiter, Coral Gables, and Orlando centers. Contact our team to request an appointment at the Florida location that works best for you.
