## Our record (each figure with its as-at date)
- Mammograms done: 25,000+ (as at 30 September 2026). Screening mammograms done since the first unit went on the road in March 2023. These are examinations, not different women.
- Fleet and reach: 7 mobile 3D units, 5 bases, 300+ communities, all nine provinces (as at 30 September 2026). Every unit has 3D tomosynthesis. We count a community once, however many times we have visited it.
- Reporting: Standard: report to the referring doctor within 3 to 5 working days. Measured: 2.3 working days on average from 1 August to 30 September 2026 (as at 21 October 2026 (standard); 30 September 2026 (measured)). The standard is what we promise every client. The measured average is what we achieved over the period shown. They are two different things, so we publish both.
- Suspicious findings referred: 425+ (as at 30 September 2026). BI-RADS 4 to 5 findings referred for biopsy since March 2023. This counts referrals, not cancers. Confirmed diagnoses are with the treating doctor.
- Follow-up: Every abnormal result phoned through by a person (as at Standing practice). The woman and her referring doctor are both called. Every woman screened goes onto the following year's recall list.
- Booking discipline: No-shows 0 to 5.5% against a 7% industry benchmark; call-to-book conversion 34.8% (as at 31 July 2026). Measured on our own booking system across the recall campaign.
- Employers: 10 signed employer agreements from 37 approaches. Named with their permission: Bankmed, Department of Health (Inxuba Yethemba Sub-District), Department of Human Resources Development, Performance and Wellness, Nursing All South Africans and Nate's Car Sales (as at 31 July 2026 (agreements); 29 October 2026 (names)). Corporate screening days booked as full unit-days at the employer's site.
- Medical scheme pilot: Close to 5,000 members screened; callbacks under 5%; satisfaction 97.7%; no adverse safety events (as at 31 July 2026). One medical scheme, not named at its request.
- Sponsored screening: Free mammograms for women without medical aid, funded through the Radhiant Foundation and delivered on community days (as at Live counter on radhiant.foundation). Pledged, delivered and still-to-deliver figures are published on the Foundation site and updated every Friday.
- HerWay: A monthly subscription from R89 that includes one screening mammogram a year, launched July 2025. 75 active subscribers and 189 included mammograms done for members since launch (as at 28 October 2026). Active subscribers are members whose subscription is running. Members whose subscription is on hold are not counted. Mammograms are examinations done for members as part of their plan.
