Patient's question:
NoDoctor's answer:
From the moment the fertilized egg implants, along with the changes in hormones within the body, the breasts also respond accordingly, such as an increase in glandular tissue and fat storage, etc. This is a natural function bestowed upon humans by nature, serving the purpose of adapting to the needs of breastfeeding after childbirth. However, this period is exactly similar to the process of secondary sexual development during a girl's adolescence.
