Coverage: Northern Ireland
Frequency: Quarterly

On 9 November 2023 the South Eastern Health and Social Care (HSC) Trust launched ‘encompass’ - a new electronic patient record system. The system also went live in Belfast Trust on 6 June 2024, in Northern Trust on 7 November 2024, and in Southern and Western Trusts on 8 May 2025. Given the relatively recent transition of Southern and Western Trusts, validated breast cancer referrals data for these Trusts were not available at the time of publication. Validated data for Belfast Trust for quarter ending June 2024, and breast cancer referrals data for this Trust for quarter ending September 2024, are also not currently available.

Data sourced from encompass are not directly comparable with data from legacy sources. Figures sourced from encompass are considered to be ‘official statistics in development’, which are a subset of Official Statistics in line with the Code of Practice for Statistics. While caution must be exercised when using these figures, they are a meaningful representation of what they measure and are of sufficient quality for publication and use.


This statistical release presents information on waiting times for cancer services at hospitals in Northern Ireland and reports on the performance of the five Health and Social Care Trusts against the draft waiting time targets which state that:

  • At least 98% of patients diagnosed with cancer should receive their first definitive treatment within 31 days of a decision to treat.
  • At least 95% of patients urgently referred by a GP with a suspected cancer should begin their first definitive treatment within 62 days.
  • All urgent breast cancer referrals should be seen within 14 days.

Information is detailed on the number of patients who began treatment by HSC Trust for all targets and by tumour site for the 31 and 62 day targets. All of the data contained in this release are published in Excel file format to facilitate secondary analysis. This file is available at the following link:

Patients seen following an urgent breast cancer referral

Data users should note that breast cancer referrals statistics are not designated as Accredited Official Statistics.

Target: All urgent breast cancer referrals should be seen within 14 days.


Given the relatively recent transition of Southern and Western HSC Trusts to the new ‘encompass’ electronic patient record system on 8 May 2025, no data for these Trusts were validated to the standard of official statistics at the time of publication.

Also on 8 May 2025, a new regional breast cancer service was launched. This service manages appointments across five hospital sites and is designed to equalise waiting times by offering patients earlier appointments outside their local Trust area. This initiative enables patients to access the earliest available appointment across Northern Ireland, irrespective of their geographical location.

As the transition to a regional service took place during a reporting quarter, the figures presented derive from both the legacy Trust breast cancer services and the new regional service. As the new breast cancer service is a regional service, breakdowns by Trust are no longer applicable and will not be provided. The numbers of referrals at each Trust are, however, set out in the ‘Breast Cancer Referrals Received’ section, which follows.

During the quarter ending June 2025, 1,947 patients were seen by a breast cancer specialist following an urgent referral in Belfast, Northern and South Eastern HSC Trusts, of which 6.6% (129) were seen within 14 days. This compares to a figure of 9.7% for these Trusts during the quarter ending March 2025. Data for quarter ending March 2025 are not directly comparable, however, as quarter ending June 2025 includes the transition period from a Trust to a regional service. During the quarter ending June 2025, the median wait time was 38 days (5 weeks 3 days) and 95% of patients were seen within 54 days (7 weeks 5 days) in Belfast, Northern and South Eastern Trusts.


Table 5: Breast Cancer Patients seen within 14 days following an Urgent Referral

Quarter Ending June 2025 Belfast, Northern and South Eastern HSC Trusts
Total number of patients 1,947
Number seen within 14 days 129
Percentage seen within 14 days 6.6%
Median wait time (Days) 38
95th percentile wait time (Days) 54

Note: Figures do not include the Southern or Western HSC Trusts as validated data for these Trusts were not available at the time of publication. A time series showing the percentage of breast cancer patients seen within 14 days following an urgent referral, from Quarter Ending June 2008 to Quarter Ending March 2025, is included as Figure 3 in previous statistical bulletins: https://www.health-ni.gov.uk/articles/cancer-waiting-times

Breast Cancer Referrals Received

Data users should note that breast cancer referrals statistics are not designated as Accredited Official Statistics.

Adding the number of referrals for suspect breast cancer at each HSC Trust to make a Northern Ireland total may inflate the ‘true demand’ on the service regionally as any referrals transferred from one Trust to another will create a duplicate referral.


Validated data for Southern and Western HSC Trusts were not available at the time of publication.

During the quarter ending June 2025, 3,803 referrals were received by Belfast, Northern and South Eastern HSC Trusts for suspect breast cancer, of which 85.2% (3,240) were classified as urgent.

During the quarter ending June 2025, the highest number of referrals (1,499) were received by the Northern HSC Trust for suspect breast cancer, of which 85.1% (1,276) were classified as urgent. The South Eastern HSC Trust received the lowest number of breast cancer referrals (1,093), however 91.3% (998) of these were urgent referrals.

A patient may be referred more than once if they are transferred to another consultant or a different Trust, or if they did not attend first treatment appointment and have been referred again.

Across each HSC Trust the number of patients referred and the percentage categorised as urgent has remained broadly steady since June 2016, with the exception of a reduction in the number of routine referrals during the quarter ending June 2020.

Data Sources, Quality and Guidance


Data sources and quality

Data used to report on the 31 and 62 day targets were formerly sourced from the Cancer Patient Pathway System (CaPPS), the data system used to administer cancer treatment services within Health and Social Care Trusts in Northern Ireland.

Data used to report on the breast cancer activity and referrals were formerly sourced from the Patient Administration System (PAS), an administrative system used to manage, record and monitor hospital waiting lists within Health and Social Care Trusts in Northern Ireland. Hospital Waits Information Branch introduced this methodology for the collection of breast cancer waiting time information in April 2017. Information was originally sourced from the Departmental SDR2 Return in aggregate format.

Data for the South Eastern HSC Trust from 9 November 2023 onwards are sourced from ‘encompass’, which is a new electronic patient record system. The system also went live in Belfast Trust on 6 June 2024, in Northern Trust on 7 November 2024, and in Southern and Western Trusts on 8 May 2025. Figures sourced from encompass are considered to be ‘official statistics in development’, which are a subset of Official Statistics in line with the Code of Practice for Statistics. While caution must be exercised when using these figures, they are a meaningful representation of what they measure and are of sufficient quality for publication and use.

Regionally consistent data collection for cancer waiting times has been in place since April 2008. Cancer referrals data has been collected from April 2016.

All data presented in this publication have been validated and quality assured by Hospital Waits Information Branch in conjunction with HSC Trusts.


31 Day Target (decision to treat to first definitive treatment)

The 31 day target relates to all patients who received a first definitive treatment for cancer during each of the three months covered in the publication, irrespective of their source or type of referral.

This is measured from the date on which the patient and the clinician agree the planned treatment and ends on the date the patient receives their first definitive treatment for cancer. Adjustments are made to the completed waiting time in the event of a patient cancelling or self-deferring treatment or because of suspension for either medical or social reasons.


62 Day Target (urgent GP referral to first definitive treatment)

The 62 day target relates to patients who received a first definitive treatment for cancer during each of the three months covered in the publication, following an urgent referral for suspect cancer from a General Practitioner (GP) or a routine GP referral that has subsequently been reclassified as urgent by a cancer specialist. Referrals from sources other than a GP, routine referrals and patients who have not been given an ICD 10 diagnosis are excluded.

This is measured from the date an initial urgent GP referral for suspect cancer is received by the HSC Trust and ends on the date the patient receives their first definitive treatment for cancer. Adjustments are made to the completed waiting time in the event of a patient cancelling or self-deferring treatment or because of suspension for either medical or social reasons.

Prior to June 2009, the target relating to waiting time for treatment following an urgent GP referral for suspect cancer was that at least 75% of patients urgently referred with a suspect cancer should begin their first definitive treatment within 62 days of referral.


14 Day Target (urgent breast cancer referrals)

Breast cancer activity reported against the 14 day target relates to all urgent referrals for suspect breast cancer that were first seen during each of the three months covered in the publication, irrespective of the source of referral. Figures include routine referrals that have subsequently been reclassified by a breast specialist as urgent and exclude urgent referrals reclassified as routine.

This is measured from the date an initial breast cancer referral is first received by the HSC Trust, and ends on the date that the patient attends their first outpatient appointment with a breast cancer specialist. Adjustments are made to the completed waiting time in the event of a patient cancelling, self-deferring or failing to attend a first outpatient appointment.


Breast Cancer Referrals

Data users should note that breast cancer referrals statistics are not designated as Accredited Official Statistics.

Figures provided in the Breast Cancer Referrals section reflect all new referrals received for suspect breast cancer irrespective of the source or urgency of referral. Referrals for breast cancer can be for advice, assessment or both.


Patients referred and treated in different Trusts

The measurement of a patient’s waiting time against the 62 day target includes cases in which a patient was initially referred to one Trust for consultant assessment but was then subsequently transferred to another Trust for treatment. In such cases, the responsibility for that patient is shared, with 0.5 allocated to the Trust where the patient was first assessed and 0.5 to the Trust of first treatment. For example, if a patient is initially referred for assessment in the Southern HSC Trust and is then transferred to the Belfast HSC Trust where they receive treatment 70 days after their initial GP referral, both the Southern and Belfast HSC Trusts will report 0.5 of a patient treated who waited over 62 days.

For the 31 day target, all patients are reported against the Trust providing their treatment.

Breast cancer activity is reported against the Trust the patient is referred to.

Breast cancer referrals are reported against the Trust the patient is referred to. However, as some referrals will be transferred to another Trust, this referral can be recorded under both the intial Trust and the Trust that has accepted transfer of the patient.


ICD 10 codes and tumour sites

The 31 and 62 day targets relate to patients who received a first definitive treatment for cancer having been given an ‘International Classification of Diseases 10’ (ICD 10) diagnosis. Patients that have not been given an ICD 10 diagnosis are excluded.

Tumour sites are assigned by aggregation of applicable ICD 10 codes.

Data for all cancers are included except for basal cell carcinoma.


Breakdown by Trust and tumour site

A breakdown of these statistics by Trust and tumour site is not routinely published due to the relatively small number of patients involved and disclosure control needed to preserve the privacy of individual patients.


Patients resident outside Northern Ireland and private patients

These statistics include patients living outside Northern Ireland and privately funded patients seen in Health and Social Care hospitals in Northern Ireland.
