Almost every teenage girl worries about breast shape or size — but here’s the truth:
It is 100% normal for one breast to grow faster than the other.
Puberty doesn’t work in perfect symmetry.
Why size differs:
• Hormones grow tissue at different speeds
• Your body is still developing
• Genetics (family pattern)
• Posture + sleeping positions
• Natural growth stages
What’s normal during puberty:
• One breast bigger
• Difference in shape
• Ni***es developing at different times
• Tenderness or mild soreness
• Slow growth
See a doctor if you notice:
• Hard lumps
• Persistent pain
• Ni**le discharge
• Sudden rapid change
• Redness + fever (possible infection)
Your body is doing its job.
Let it grow in its own time.
