Lung screening in Miami, FL is primarily recommended for adults between 50 and 80 years old who have at least a 20 pack-year smoking history and currently smoke or quit within the past 15 years. For people in this higher-risk group, annual low-dose CT may help find lung cancer at an earlier stage.
At Life Imaging, we also speak with patients whose histories are less straightforward. Some have spent years around secondhand smoke. Others have worked near asbestos, dust, fumes, or other lung irritants. These exposures may affect risk, but they do not automatically place someone within the standard criteria for annual lung cancer screening.
Our Miami center provides low-dose CT lung imaging without sedation. Screening is intended for stable adults who are not experiencing urgent respiratory symptoms. The report should be shared with a physician who can place the findings within your smoking, occupational, and medical history.
If you are unsure whether you fit the screening criteria, contact our Miami team before scheduling.
The Centers for Disease Control and Prevention recommends annual low-dose CT screening for adults who meet all three of these conditions:
Screening evidence is strongest within this age range. Age alone does not make someone eligible, since smoking history and current health also matter.
Pack-years account for both the number of packs smoked each day and the number of years a person smoked. The calculation helps estimate cumulative tobacco exposure.
Lung cancer risk falls after a person stops smoking, but the decline takes time. Former smokers may remain eligible for annual screening for up to 15 years after quitting.
All three criteria should be considered together. A 55-year-old who smoked occasionally for a few years does not have the same risk profile as someone of the same age with a 30 pack-year history.
Screening decisions also need to account for overall health. Annual screening may no longer be appropriate when a serious medical condition substantially limits life expectancy or makes a person unable or unwilling to receive treatment if lung cancer is found.
The calculation is simpler than the term sounds. Multiply the average number of cigarette packs smoked each day by the number of years you smoked. For example:
Smoking patterns are not always consistent. You may have smoked heavily for several years, stopped for a while, and later started again. In that case, calculate each period separately and add the totals. If you do not remember the exact amount, make the most accurate estimate you can — your physician can help you work through changes in your smoking history.
Vaping, cigar use, and secondhand smoke exposure are not converted into cigarette pack-years using the same formula. Mention them to your physician, but do not try to force those exposures into the calculation.
Former smokers may qualify if they stopped within the past 15 years and meet the age and pack-year criteria. Quitting does not erase past exposure overnight — lung cancer risk gradually decreases over time, which is why people can remain eligible for screening years after their final cigarette. The CDC explains that quitting smoking lowers cancer risk, including the risk of lung cancer. The benefit continues to grow with time.
Keep track of the month and year you quit. That information helps your physician decide:
Lung screening is not a replacement for quitting. If you currently smoke, stopping remains one of the most important steps you can take for your lung and overall health.
Smoking history is the main factor used in current annual screening recommendations. Other exposures can still matter, even when they do not create automatic eligibility.
Long-term secondhand smoke exposure can increase lung cancer risk. This may include years spent living with someone who smoked indoors or working in an environment where tobacco smoke was common. Current national screening criteria do not rely solely on secondhand exposure to determine annual low-dose CT eligibility.
Some Miami residents have worked in construction, shipyards, automotive repair, manufacturing, aviation, maintenance, or other jobs involving airborne materials. The National Cancer Institute identifies asbestos and several occupational substances as lung cancer risk factors. An occupational exposure does not automatically mean annual LDCT is recommended.
Family history may affect personal risk, particularly when a parent, sibling, or child has had lung cancer. The age at diagnosis, smoking history, and number of relatives affected provide useful context — but family history alone is not part of the standard annual LDCT criteria.
Radon is a naturally occurring radioactive gas that can collect inside buildings. Long-term exposure increases lung cancer risk, especially among people who smoke. A home radon test measures the building, not your lungs.
Low-dose CT lung screening is intended for people who do not have symptoms suggesting an active lung problem. When symptoms are present, the goal changes from screening to diagnosis. Seek medical evaluation if you have:
Even a small amount of blood should be discussed with a healthcare professional rather than handled through a routine screening appointment.
A cough that persists, becomes more frequent, or feels different from your usual smoker’s cough needs clinical attention.
Sudden breathing difficulty can be an emergency. Gradually increasing breathlessness should also be assessed by a physician.
New chest pain can have several causes involving the heart, lungs, muscles, or digestive system. Urgent or severe pain requires prompt care.
These changes do not automatically indicate lung cancer, but they deserve medical evaluation when they are persistent.
Recurring infections in the same lung region may require diagnostic imaging and a physician-led investigation.
Do not delay care while waiting for a screening appointment. A physician may order a diagnostic chest CT, chest X-ray, laboratory work, pulmonary testing, or another examination based on the symptoms.
A chest X-ray produces a flat image in which bones, organs, and tissues overlap. Low-dose CT creates a series of cross-sectional images that allow the lungs to be reviewed in greater detail. This difference matters when the goal is to identify small lung nodules.
The National Cancer Institute’s National Lung Screening Trial found that screening high-risk participants with low-dose CT reduced lung cancer deaths compared with chest X-ray screening. That evidence applies to people at elevated risk — it does not prove that yearly CT benefits every adult, regardless of smoking history. Low-dose CT also differs from a standard diagnostic chest CT, which may use a higher dose, contrast dye, or a protocol designed to investigate symptoms or a known medical issue.
Low-dose CT can show small nodules and other structural changes within the lungs. A nodule is a small area that looks different from the surrounding lung tissue. Most lung nodules are not cancer — they can result from an earlier infection, inflammation, scar tissue, or another benign cause. The radiologist assesses characteristics such as size, shape, density, and location before recommending the next step. The scan may also reveal:
A screening scan cannot diagnose every lung condition. It also cannot confirm cancer on its own. A suspicious finding may require repeat imaging, diagnostic CT, PET imaging, specialist review, or tissue sampling.
Screening has a demonstrated benefit for people at high risk, but it also has limitations.
A scan may identify a nodule that is not cancer. Follow-up imaging is often sufficient to show that the area remains stable, but certain findings may warrant additional tests or procedures.
Low-dose chest CT may capture part of another organ or structure. An unexpected finding outside the lungs may require separate evaluation, even if it turns out to be harmless.
LDCT uses less radiation than a standard diagnostic CT, but annual screening creates repeated exposure. The potential benefit should outweigh that risk.
Screening can occasionally identify a cancer that would not have caused symptoms during the person’s lifetime. This may lead to treatment that would otherwise have been unnecessary.
A normal screening result does not mean you can ignore a future cough, breathing change, or chest pain. It also does not protect against cancer developing between annual scans.
The CDC’s lung screening guidance recommends discussing these potential benefits and harms with a physician before starting annual screening.
Our lung screening in Miami uses low-dose CT and does not require sedation. You lie on the scanner table, usually with your arms positioned above your head. The table moves through the machine’s open center while the images are captured. Our technologist may ask you to hold your breath briefly to reduce motion. Tell our team before the examination if you:
The scan itself is generally quick. Most patients can return to their usual activities without a recovery period.
Your report may show no suspicious findings, recommend another screening in one year, or advise earlier follow-up for a nodule or another change. If the result is reassuring, continue following the screening schedule recommended by your physician — annual screening works as a series, not as a one-time test for people who remain eligible. If a nodule is noted, do not assume it is cancer; your physician will consider its size, appearance, and any previous scans before recommending the next step.
Follow-up may involve:
Keep copies of your reports. Changes over time are often more informative than a single image.
Our Miami center is located at 2344 S Douglas Road in Coral Gables. We see patients from Coral Gables and surrounding communities, including Coconut Grove, Brickell, South Miami, Key Biscayne, Kendall, and other parts of Miami-Dade County.
Miami residents bring varied health and work histories. Some have lived in different countries or states. Others have spent years in construction, hospitality, transportation, aviation, automotive work, or jobs involving dust and fumes. Tell your physician and us about your full exposure history, not only what happened after you moved to Miami — lung risk reflects years of smoking, work, home environments, and medical history.
Location does not change the national screening criteria. It does change the personal history each patient brings to the decision.
At our Coral Gables center, we focus on preventive imaging that gives patients clear information to review with their healthcare providers. Patients choose us for:
Our lung screening is noninvasive and requires no recovery period. The appointment can usually fit into a normal day.
We explain what will happen during the scan and ask about information that may affect whether screening is appropriate.
The images are interpreted and documented in a written report that can be shared with your primary care physician or specialist.
Our Coral Gables center serves patients from nearby Miami communities and provides several preventive imaging services in one location.
We provide preventive screening information. Diagnosis, treatment, smoking cessation support, medication, and specialist referrals remain with qualified healthcare providers.
If you are trying to calculate your pack-year history or understand whether your smoking history fits the criteria, contact our team before scheduling.
Lung screening is most useful when it is offered to the right person and followed by a clear plan. If you are between 50 and 80, have at least a 20 pack-year history, and currently smoke or quit within the past 15 years, speak with your physician about annual low-dose CT. We can explain the appointment, help you prepare for the visit, and provide a written report for physician review. If you fall outside the standard criteria but have other concerns, your physician can help decide whether screening or another form of evaluation is appropriate. Contact Life Imaging today to schedule lung screening at our Coral Gables center and bring your complete smoking and exposure history to the conversation.
