Question to the Department of Health and Social Care:

To ask the Secretary of State for Health and Social Care, how many UK residents received proton beam therapy (a) domestically and (b) overseas under NHS commissioning arrangements in each of the last five financial years.

The Department oversees healthcare in England but does not routinely track how many residents have received proton beam therapy, either domestically or abroad, in the past five years.

We also do not routinely collect data on patients eligible for this treatment, associated out-of-pocket costs, and the number of individuals who have self-funded their therapy.
