In a rare moment of cross-party unity, Parliament is fast-tracking legislation that could transform care for thousands of cancer patients left behind by the system. This week on Deep Dive, we investigate the surprising political story behind the Rare Cancers Bill – and why MPs who can’t agree on Brexit or budgets are suddenly aligned on this issue.

We’ll unpack:

• The shocking math behind so-called "rare" cancers (spoiler: they cause 55% of UK cancer deaths)

• How a grieving sister’s bake sale sparked a clinical trial – and changed the political calculus

• Why pharmaceutical giants avoid these treatments – and what the bill does to change that

• The quiet NHS data revolution that could put UK patients at the front of the queue for breakthrough therapies
