Mobile diagnostic units that biopsy, scan and treat on the same visit
Vans equipped with ultrasound, biopsy kits, cervical screening and a link to a distant pathologist could bring a cancer diagnosis, and for cervical pre-cancer immediate treatment, to villages far from any hospital.
Rural patients in LMICs often make three or four long trips before diagnosis, and many drop out. A mobile unit staffed by a nurse and a clinical officer, carrying portable ultrasound, core-biopsy equipment, HPV testing and thermal ablation, and connected to a telepathology hub, compresses the pathway into one or two visits. Mobile breast and cervical screening exists in several countries; combining diagnosis and treatment in one visit is the new step.
Hypothesis
Communities served by a see-and-treat mobile unit will show a higher proportion of breast and cervical cancers diagnosed at stage I-II and a lower loss-to-follow-up between suspicion and diagnosis than matched communities relying on referral.
Rationale
Each additional visit before diagnosis loses a fraction of patients to cost and distance; collapsing visits is the single most effective adherence intervention in resource-limited care.
What would test it
Cluster-randomised evaluation across 20 rural districts with stage distribution, loss to follow-up, and cost per early-stage cancer detected as endpoints.

Bottlenecks it attacks
- Most of the world has almost no cancer care · Seven in ten cancer deaths happen in low- and middle-income countries, where radiotherapy, pathology, surgery and drugs are scarce.
- Most lethal cancers are found late · Screening exists for only a few cancers. Pancreatic, ovarian, liver, oesophageal and most lung cancers are found when cure is unlikely.
