## TL;DR

In Great Britain most people with cancer need not tell the DVLA, unless the cancer affects the brain or nerves, a doctor says they may be unfit to drive, or medicines affect driving. Before travelling abroad, ask the cancer team whether it is safe, avoid live vaccines unless the team agrees, carry medicines and a doctor's letter in hand luggage, and declare the cancer to the travel insurer.

## Summary

The UK driving rules are law, not clinical guidance. The DVLA requires a car or motorcycle driver with cancer to tell it only if they develop problems with the brain or nervous system, a doctor says they might not be fit to drive, they are restricted to certain or adapted vehicles, or medication side effects could affect driving; bus, coach and lorry drivers must tell it if the condition will affect driving. Failing to declare a condition that affects driving carries a fine of up to £1,000. Under the drug-driving law in England, Scotland and Wales, prescribed opioids and benzodiazepines may be taken while driving only if they were prescribed, taken as advised, and are not impairing. Macmillan's travel guidance (2023, under review) says to ask the cancer team before flying, names reasons people may be advised not to fly (low platelets, raised pressure from a brain tumour, recent brain, chest, bowel or eye surgery), notes the clot risk of long flights, says live vaccines must not be given during or recently after chemotherapy or radiotherapy and some targeted or immunotherapy drugs, advises seeing a travel health professional at least 8 weeks before travel, carrying medicines and a doctor's letter in hand luggage in original packaging, and always declaring pre-existing conditions to the insurer. None of this is graded, and the CDC Yellow Book chapter on immunocompromised travellers could not be read.
