How this affects your claim in practice
In an occupational cancer claim, the diagnosis is only the starting point. The records should connect pathology and oncology records identifying the exact cancer, site, stage and treatment and a detailed occupational exposure history with dates, tasks, products and control measures with the worker's practical limits, including fatigue, infection risk, organ function, treatment timing, cognition, exposure restrictions and attendance reliability and whether duties can be sustained through the proposed hours and treatment cycle. If the insurer disputes whether employment was the main contributing factor to contracting the disease unless a specific statutory pathway or presumption applies, the response should address that reason directly.
Assessment source
- NSW Guidelines for the Evaluation of Permanent Impairment, paras 1.8-1.12: NSW Guidelines control the assessment method and AMA5 is used only where adopted and not modified.
- NSW Guidelines para 1.12: AMA5 Chapter 18 pain is excluded; chronic pain is assessed through the underlying diagnosed condition, while CRPS is assessed under the relevant NSW method.
- NSW Guidelines para 1.15: assessment should usually wait until maximum medical improvement, meaning the condition is stable and unlikely to change substantially in the next year.
- NSW Guidelines Chapter 8, paras 8.3-8.4 and 8.15-8.16: respiratory disorders other than asthma use AMA5 Table 5-12, with valid physiological testing and a reasoned whole-number selection within Classes 2-4.
- NSW Guidelines paras 8.5-8.7: asthma uses the modified AMA5 Tables 5-9 and 5-10 score from repeat testing under maximal treatment; bronchial challenge testing and PC20 are not scored.
- NSW Guidelines para 8.12: pneumoconiosis is dealt with under the separate NSW dust-diseases legislation rather than the ordinary Chapter 8 WPI pathway.
- NSW Guidelines Chapter 14, paras 14.3-14.9 and Table 14.1 (TEMSKI): non-facial scars, grafts and skin conditions are assessed as one skin organ by best fit across appearance, contour or adherence, activities of daily living and treatment.
- NSW Guidelines para 14.6: a visible scar may rate 0% WPI, and an uncomplicated scar from a standard surgical procedure does not by itself rate an impairment.
- AMA5 Table 8-2 applies to more substantial skin impairment subject to the NSW modifications; facial disorder or disfigurement instead uses NSW Table 6.1.
- Workers Compensation Act 1987 (NSW), s 4(c): a dust disease within the Dust Diseases Act is excluded from the ordinary Act definition of injury, subject to the statutory exception for a worker employed in or about a mine.
- Workers' Compensation (Dust Diseases) Act 1942 (NSW), s 3 and Schedule 1: asbestosis and silicosis are scheduled dust diseases dealt with under the separate dust-diseases scheme.
- SIRA permanent-impairment Guidelines para 8.12: pneumoconiosis is not assessed under the ordinary respiratory WPI chapter because the separate dust-diseases legislation applies.
- icare Dust Diseases Care assesses the covered diagnosis, harmful occupational dust exposure while employed in NSW and disability from the disease. Its medical and benefit process is not an ordinary section 66 WPI calculation.
- Workers Compensation Act 1987 (NSW), ss 4(a), 4(b) and 9A: an acute personal injury and a disease injury use different employment-causation tests. A disease contracted or aggravated after the 2012 amendments requires employment to be the main contributing factor; a non-disease injury generally requires employment to be a substantial contributing factor.
- The legal liability test and the permanent-impairment method answer different questions. Establishing workplace exposure does not itself select a WPI chapter, class or percentage.
Occupational conditions and exposure patterns
Occupational cancer is not a single impairment category. The accepted diagnosis must identify the structure or body system affected and the permanent consequence being assessed.
- A supported work mechanism: long-latency exposure to an identified occupational carcinogen supported by the work history.
- A supported work mechanism: repeated ultraviolet exposure causing skin cancer in outdoor work.
- For occupational cancer, separate diagnoses and consequential conditions should be recorded individually so that one broad injury label is not used for different assessment methods.
Symptoms and findings that matter
A finding relevant to occupational cancer: pathology and oncology records identifying the exact cancer, site, stage and treatment.
A finding relevant to occupational cancer: a detailed occupational exposure history with dates, tasks, products and control measures.
A finding relevant to occupational cancer: specialist causal opinion addressing latency, dose and relevant non-work factors.
Fatigue, infection risk, organ function, treatment timing, cognition, exposure restrictions and attendance reliability.
What investigations are usually relevant
Investigations for occupational cancer may include pathology and oncology records identifying the exact cancer, site, stage and treatment and a detailed occupational exposure history with dates, tasks, products and control measures. Each result should answer a defined clinical question and be read with the examination, diagnosis and history.
- Specialist causal opinion addressing latency, dose and relevant non-work factors.
- Organ-function, recurrence, treatment-effect and maximum-medical-improvement evidence.
How WPI is assessed for this body part
Occupational cancer has no universal WPI table. The exact cancer, accepted occupational cause, treatment result and body system determine the assessment method.
For an ordinary lung-cancer WPI assessment, NSW paragraph 8.13 requires assessment at least six months after surgery using AMA5 Table 5-12. Residual lung cancer after treatment is placed in Respiratory Class 4 under paragraph 8.14.
Skin cancer consequences may use the NSW skin or facial method. A cancer scheduled under the dust-diseases legislation may instead require the Dust Diseases Care pathway rather than an ordinary section 66 assessment.
Treatment consequences in another body system are assessed only where accepted, stable and not already captured by the primary method.

Method illustration
This is a non-numeric illustration of the assessment sequence. It does not predict a WPI result.
- Accepted condition and findings
- Occupational cancer is not a single impairment category. The accepted diagnosis must identify the structure or body system affected and the permanent consequence being assessed. A finding relevant to occupational cancer: pathology and oncology records identifying the exact cancer, site, stage and treatment.
- Method to apply
- Occupational cancer has no universal WPI table. The exact cancer, accepted occupational cause, treatment result and body system determine the assessment method.
- Why no percentage can be assumed
- A cancer diagnosis, treatment intensity, remission status or surveillance schedule does not by itself select WPI.
What usually does not increase WPI
A cancer diagnosis, treatment intensity, remission status or surveillance schedule does not by itself select WPI.
Occupational exposure must be addressed under the applicable liability or statutory pathway; latency and dose evidence do not replace the impairment method.
Separate treatment effects should not be added where they duplicate loss already captured by the selected body-system class.
Evidence checklist
The records for occupational cancer should include oncology, surgery, radiotherapy, medication, surveillance and rehabilitation where clinically supported. They are most useful when the diagnosis, examination and practical restrictions are consistent.
How this injury commonly happens at work
Work-related occupational cancer can arise through long-latency exposure to an identified occupational carcinogen supported by the work history and repeated ultraviolet exposure causing skin cancer in outdoor work. The chronology should identify the actual task or event and when symptoms or function changed.
Work-related occupational cancer can arise through asbestos, silica, diesel exhaust, chemicals, radiation or another agent where specialist evidence addresses the particular cancer. The chronology should record the actual task or event and the point at which symptoms or function changed.
Common insurer disputes
For occupational cancer, an insurer may dispute whether employment was the main contributing factor to contracting the disease unless a specific statutory pathway or presumption applies and whether the cancer is a scheduled dust disease requiring Dust Diseases Care rather than the ordinary scheme. The written decision should be answered with evidence directed to those reasons.
Further disputes about occupational cancer may concern whether the claimed permanent consequence arises from the cancer, its treatment or another condition and whether the assessment occurred after the condition and treatment had stabilised. The decision notice should identify which issue is relied on and the evidence said to support it.
Treatment and surgery issues
Depending on the diagnosis and treating opinion, management of occupational cancer may involve body-system-specific care for lasting treatment consequences. The request should explain the expected functional benefit and its connection to the accepted injury.
Weekly payments and work capacity
Capacity evidence for occupational cancer should address whether duties can be sustained through the proposed hours and treatment cycle and whether a separate body-system consequence requires specific restrictions. Proposed duties must be sustainable for the proposed hours, not merely possible once.
How NSW Work Injury Claim can help
For occupational cancer, a claim review can help to identify the exact diagnosis, exposure agent, latency and statutory pathway and organise pathology, oncology, industrial-history and stable functional evidence. The purpose is to identify the precise decision and the evidence needed for the next available step, not to promise an outcome.
For occupational cancer, a claim review can help to separate disease causation, treatment, work capacity and permanent consequences. The purpose is to identify the precise decision and the evidence needed for the next available step, not to promise an outcome.
Common questions about occupational cancer claims
How can work cause or aggravate occupational cancer?
For occupational cancer, the relevant work history may include long-latency exposure to an identified occupational carcinogen supported by the work history, repeated ultraviolet exposure causing skin cancer in outdoor work, and asbestos, silica, diesel exhaust, chemicals, radiation or another agent where specialist evidence addresses the particular cancer. A claim still depends on the actual chronology and medical evidence. The records should identify what changed, when symptoms began or worsened, and how the diagnosed condition affects the worker's duties.
How is WPI assessed for occupational cancer?
For occupational cancer, occupational cancer has no universal WPI table. The exact cancer, accepted occupational cause, treatment result and body system determine the assessment method. A finding relevant to occupational cancer: pathology and oncology records identifying the exact cancer, site, stage and treatment. The assessor must apply the NSW Guidelines to the accepted, stable condition; the diagnosis or an operation does not by itself determine a percentage.
Which records are most useful for an occupational cancer assessment?
An occupational cancer assessment commonly needs pathology and oncology records identifying the exact cancer, site, stage and treatment, a detailed occupational exposure history with dates, tasks, products and control measures, specialist causal opinion addressing latency, dose and relevant non-work factors, and organ-function, recurrence, treatment-effect and maximum-medical-improvement evidence. Those records are most useful when they describe the same diagnosis, examination findings, treatment history and practical work restrictions.
What does an insurer commonly dispute about occupational cancer?
For occupational cancer, common issues include whether employment was the main contributing factor to contracting the disease unless a specific statutory pathway or presumption applies, whether the cancer is a scheduled dust disease requiring Dust Diseases Care rather than the ordinary scheme, and whether the claimed permanent consequence arises from the cancer, its treatment or another condition. The response should address the insurer's stated reason with the relevant chronology, clinical findings, investigations and duties evidence rather than relying on the diagnosis alone.
How can occupational cancer affect weekly payments and suitable duties?
Capacity evidence for occupational cancer may need to address fatigue, infection risk, organ function, treatment timing, cognition, exposure restrictions and attendance reliability, whether duties can be sustained through the proposed hours and treatment cycle, and whether a separate body-system consequence requires specific restrictions. A certificate should describe what the worker can do safely and sustainably. Proposed duties should then be checked against those restrictions and the real demands of the job.
Does occupational cancer automatically receive a fixed WPI percentage?
No. For occupational cancer, one verified example is ordinary lung cancer after surgery: Assess at least 6 months after surgery under Table 5-12, under NSW Guidelines para 8.13. That value applies only when its stated criteria are met. A cancer diagnosis, treatment intensity, remission status or surveillance schedule does not by itself select WPI.
