When it comes to brain tumours, a patient's sex matters

Different genes drive cancer growth in males and females, say researchers

Have you ever wondered why, in most species, males are larger and more ornamented than females?


It’s an evolutionarily determined aspect of biology, but what does it mean for human health and disease? What are the implications of needing one chart to describe normal growth in boys, and another to describe normal growth in girls? Why are there two normals for growth, and does it matter for a disease of growth like cancer?
