Firefighter Cancer Screening: IAFF Guidance and Test Options

The International Association of Fire Fighters (IAFF) has released its updated Cancer Screening Guide (April 2025), designed to support firefighters in understanding and accessing evidence-based cancer screenings. This comprehensive resource underscores the heightened cancer risks associated with firefighting and provides practical recommendations aligned with NFPA 1582, the U.S. Preventive Services Task Force, and the American Cancer Society.

The guide also reviews emerging options, including multi-cancer early detection tests and diagnostic services. United Diagnostic Services (UDS) is specifically referenced in Section 4: Commercial Tests and Services (pages 14–16), where it is compared alongside other providers for its role in delivering specialized cancer screenings to the fire service community.

Key Takeaways from the IAFF Cancer Screening Guide (April 2025)

Section 1: Cancer Screenings

What is a cancer screening?
Cancer screening is testing for certain cancers in people without symptoms, with the goal of finding disease early when it is more treatable.

Why it matters for firefighters:
Firefighters face higher rates of cancer because of repeated exposure to carcinogens in smoke, soot, gear, and fireground environments. Screening is essential to detect disease before symptoms develop.

Cancers that can be screened for include:

Skin cancer: Firefighters have elevated risk for melanoma, basal cell carcinoma, and squamous cell carcinoma. Annual skin exams are recommended.
Lung cancer: Low-dose CT scans are used in at-risk firefighters.
Prostate cancer: PSA blood test and digital rectal exam, generally starting at age 50, or earlier (40+) for high-risk groups.
Breast cancer: Mammograms for women, starting at age 40.
Colon cancer: Stool tests, sigmoidoscopy, or colonoscopy, starting between ages 40–45 depending on risk factors.

Section 2: Annual Fire Fighter Physical Exam

Overall purpose:
Annual physical exams help firefighters stay fit for duty while also identifying chronic and acute health issues early, especially cancers, cardiovascular disease, and respiratory illness.

Cancer detection role:
Because cancer is the leading cause of occupational death among firefighters, annual exams are critical checkpoints. Exams should look for:

Unexplained weight loss, fatigue, malaise
Abnormal moles or skin lesions
Neurological issues (imbalance, vision changes, confusion)
Abnormal bloodwork (e.g., elevated WBC count, thyroid or liver function abnormalities)
Abnormal lung function on spirometry or imaging

These annual exams provide a structured opportunity to discuss preventive health, including nutrition, exercise, smoking cessation, and alcohol use.

Section 3: NFPA 1582 and Cancer Screenings

What is NFPA 1582?
It is the Standard on Comprehensive Occupational Medical Program for Fire Departments, designed to ensure firefighters are medically evaluated for job performance and long-term health.

Source of recommendations:
NFPA 1582 cancer screening guidance is based on:

U.S. Preventive Services Task Force (USPSTF)
American Cancer Society (ACS)
Fire service medical experts

Adjustments for firefighter risk:
NFPA often recommends earlier screening than general population standards:

Colon cancer: USPSTF begins at 45; NFPA recommends starting discussion at 40.
Prostate cancer: USPSTF begins at 55; NFPA advises 50 (or 40 for high-risk groups).
Lung cancer: USPSTF/ NCCN recommends for smokers age 50+ with 20 pack-year history; some experts argue annual screening should extend to non-smokers with heavy fireground exposure.

Cancers covered in NFPA 1582 screenings include:

Oral cavity and nasopharynx
Thyroid
Skin
Breast
Lung
Prostate and testicular
Cervical
Colon

Why some cancers lack screenings:
For cancers like ovarian, pancreatic, brain, or multiple myeloma, no validated population-level screening test currently exists.

Section 4: Commercial Tests and Services

The guide highlights the growing market of multi-cancer early detection (MCED) blood tests and specialized screening providers.

Examples of MCED tests:

OneTest™ – protein biomarkers
Galleri® (GRAIL) – cfDNA methylation; claims >50 cancers detected
ONCOblot® – ENOX2 protein for tumor origin
IvyGene® – DNA methylation for breast, colon, liver, lung
Aristotle® – mRNA-based, focused on gynecologic and colorectal
Guardant – liquid biopsy mutation profiling

Test comparisons (from guide):

Galleri: $949, 51.5% sensitivity, 99.5% specificity
OneTest: $189, ~82% sensitivity (male cohort)
IvyGene: $400, 84% sensitivity in major cancers

Diagnostic service providers compared in the guide:

Life Scan Wellness Centers – ultrasound exams, labs, cancer screens, includes PSA and CA-125 (not NFPA standard).
United Diagnostic Services (UDS) – provides ultrasound, cardiac and lung screenings, PSA, thyroid checks, mammography. Structured to align with NFPA 1582 core requirements plus supplemental diagnostics.

Other services noted:

Imaging options: CT, ultrasound, MRI
AI screening tools: DermaSensor (skin), iCAD (mammography)
Novel research: breath biomarkers, detection dogs, AI triage

Section 5: Frequently Asked Questions (FAQs)

What cancer screening tests does the IAFF recommend?
Evidence-based tests such as mammograms, colonoscopy, low-dose CT scans, Pap smears, PSA.

Why doesn’t IAFF recommend commercial MCED tests yet?
They are still investigational, not FDA-approved for general use, and lack validation for routine screening. IAFF advises they only be considered in research contexts.

What do other medical organizations say?
The ACS acknowledges MCED promise but does not recommend them for routine screening. USPSTF has not adopted them.

What defines a good screening test?

Detects cancers early
High sensitivity/specificity
Minimally invasive
Supported by evidence of survival benefit

What defines a poor screening test?

Inaccurate with false results
Invasive with little clinical value
Lacks survival benefit
Expensive without justification

Section 6: Summary and Conclusion

Cancer is a leading firefighter health threat.
NFPA 1582 provides the foundation for proven, evidence-based screening.
Commercial diagnostic options may be considered as supplements, not replacements.
Firefighters should:
- Adhere to NFPA-aligned screenings
- Reduce carcinogen exposures
- Maintain healthy habits
- Consult healthcare providers before adding new technologies

Frequently Asked Questions

What is the IAFF?

The International Association of Fire Fighters (IAFF) is the largest union representing professional firefighters and paramedics in the U.S. and Canada. With more than 340,000 members, the IAFF advocates for firefighter safety, health, and working conditions.

What is the IAFF Cancer Screening Guide (April 2025)?

The IAFF Cancer Screening Guide is an updated resource that explains evidence-based cancer screenings for firefighters. It aligns with NFPA 1582 standards and reviews both traditional screenings and emerging diagnostic services.

Why are firefighters at higher risk for cancer?

Firefighters are regularly exposed to carcinogens in smoke, soot, and chemicals. Research shows they have higher rates of cancers such as lung, skin, prostate, and colon cancer, often at younger ages than the general public.

What cancer screenings does the IAFF recommend?

The guide highlights evidence-based screenings, including:

Skin exams (annual)
Lung scans (low-dose CT for at-risk firefighters)
Prostate screening (PSA starting at age 50, or earlier for high-risk groups)
Breast cancer (mammograms for women beginning at 40)
Colon cancer (stool tests or colonoscopy starting at 40–45)

What are commercial cancer screening services?

Beyond standard exams, the guide reviews new options such as multi-cancer early detection (MCED) blood tests and commercial diagnostic programs. Section 4 (pages 14–16) compares providers, including United Diagnostic Services (UDS).

Does the IAFF endorse specific commercial providers?

No. The IAFF does not formally endorse commercial services. These options should be seen as supplements to – not replacements for – evidence-based screenings outlined in NFPA 1582.

What does this mean for firefighters personally?

For individual firefighters, the guide offers a roadmap to ask the right questions during annual physicals, pursue recommended screenings, and stay proactive about long-term health.

What does this mean for fire chiefs and union leaders?

For leadership, the guide is a framework for building stronger occupational health programs. Chiefs and union leaders can use it to evaluate screening vendors like UDS, set department-wide standards, and improve firefighter wellness outcomes.
