According to standardized incidence ratios, the large volume of undetected cancer cases related to the COVID-19 pandemic in Madrid has not returned yet to the reference levels. Breast and lung cancer screening programs have recovered completely, but other very prevalent malignancies including colorectal, prostate or bladder cancer still remain severely impacted. These figures may have serious consequences in the future regarding both cancer control and survival. In order to mitigate the long-term consequences of the COVID-19 pandemic strategies to recover the backlog of diagnoses need be considered.  \nAbstract: The coronavirus disease 2019 (COVID-19) pandemic has caused a significant disruption to cancer diagnosis, treatment and prevention worldwide that could have serious consequences in the near future.
