## TL;DR

Cervical cancer cannot be cured by external radiotherapy alone; it needs brachytherapy, internal radiation that LMIC radiotherapy centres frequently lack or cannot keep running because iridium-192 sources must be replaced every three months. Cobalt-60 sources last about five years and give equivalent doses, so funding cobalt units for every regional centre closes a well-understood cure gap.

## Summary

Brachytherapy is essential for curative cervical cancer treatment, yet LMIC radiotherapy centres frequently have none, or have units whose iridium-192 sources cannot be replaced every three months for cost and logistics reasons. Cobalt-60 HDR sources last about five years and are dosimetrically equivalent for cervix. A programme to fund cobalt HDR units, standardise applicators and image-guided planning, and train teams would close a specific and well-understood cure gap.

## Fields

- Kind: Idea
- Last checked: 2026-09-08
- Hypothesis: Regional centres receiving a cobalt HDR unit and training will increase the proportion of locally advanced cervical cancer patients completing brachytherapy within the recommended overall treatment time from under 40% to above 80%.
- Rationale: The technology is proven and the indication is common; the constraint is a solvable procurement and training problem with a defined cost.
- Proposed test: Before-and-after audit of brachytherapy completion, overall treatment time, and three-year local control in ten centres receiving units.
- Maturity: early-clinical
- Actor: engineering
