The global incidence of cancer reached 20 million in 2022 and is projected to rise to 33·1 million by 2050.1 Amid the growing cancer epidemic, the ability to provide appropriate care for patients is compromised not only by inadequate infrastructure and treatment options, but also by the paucity of needed personnel. Latin America and the Caribbean, which comprise 33 countries—44% of them low or middle income—are known to have large oncology workforce shortages. For example, according to an analysis of Global Cancer Observatory data, Brazil had only 646 radiation oncologists and 533 medical physicists in 2022, leaving deficits of 960 and 359, respectively, compared with estimated needs; together, these deficits constituted the second-highest gap in radiotherapy professionals among 32 countries of varying income levels included in the report.
