What causes breast pain in early twenties?

Q: My 21 years old friend has been experiencing breast pain for the last four years. Once she went to a doctor who told her that it is because of growth. Please tell me the cause and treatment of breast pain?

A:Breast pain at this age is usually due to a non- cancerous disease called fibroadenosis, which can be diagnosed by ultrasound of breasts. She can get that done and if that is the case, vitamin E 600 mg daily will give her relief.
