What happened

Doctors have hailed “unprecedented” trial results that show a triple-action cancer jab can eradicate entire tumours in patients.

Why it matters

In an international trial spanning 11 countries, the injection was offered to patients whose cancer had spread or come back and whose disease had failed to respond to other treatments.

Common ground

The jab, called amivantamab, shrank the tumours of more than a third of patients, with dramatic changes seen within weeks.

Perspective signals

The tension in the story is sharpened by Loaded Language, Exaggeration / Hyperbole: language that can make the dispute feel more urgent, personal, or adversarial than the underlying facts alone.
