Scientists just discovered we’ve been looking at cancer growth all wrong

A new study has found evidence that brain tumours use fat as their preferred source of energy, bringing into question the decades-long assumption that sugar is their main fuel source. If confirmed, this could fundamentally change the we treat cancer … Continue reading
