At the age of 8-13 years all women face some sort of change in their life. The start of menstruation, changes of the body and mind (Ghai, 2012). Hormonal changes stimulate this change in them (Hall, 2010). One of the changes is the development of breasts (Hall, 2010). The breast is a body part, which differs in size and function in male and female bodies. The female breast contains the mammary gland which produces milk to feed infants (Boron & Boulpaep, 2012). Both men and women develop their breast from the same embryological tissues (Hall, 2010). In puberty different hormones especially estrogen works in breast development (Russo & Russo, 2008). On the other hand male hormone testosterone doesn’t have this function.

Zielsetzung und Themenschwerpunkte (Objectives and Key Themes)
This text focuses on the impact of hormones on breast tissue and the implications of genetic mutations, specifically BRCA 1 and BRCA 2, on breast cancer risk. It explores how hormonal changes affect breast density and the significance of these changes for breast imaging, particularly MRI. Additionally, the text discusses screening and management strategies for individuals with BRCA gene mutations.

Zusammenfassung der Kapitel (Chapter Summaries)
The introductory chapter provides an overview of the text, outlining the focus on hormonal effects on breast tissue and the role of MRI in breast imaging. It highlights the significant changes that occur in women during puberty and the role of hormones in breast development.
The second chapter delves into the hormonal fluctuations during the menstrual cycle and their impact on breast tissue. It examines how estrogen and progesterone influence breast density and the potential implications of these changes for mammographic screening. The chapter also discusses the importance of MRI in detecting changes related to hormonal fluctuations.
The third chapter focuses on BRCA 1 and BRCA 2 genes, their role in tumor suppression, and the consequences of mutations in these genes for breast cancer risk. It explores the management strategies for individuals with BRCA gene mutations, including intensive cancer screening programs, prophylactic mastectomy, and other interventions.
Schlüsselwörter (Keywords)
The primary focus of this text lies in the intersection of breast tissue, hormones, genetics, and breast cancer. Key terms and concepts include hormonal influences, breast density, MRI, BRCA 1 and BRCA 2 gene mutations, screening strategies, prophylactic mastectomy, and implant ruptures.
Frequently Asked Questions
How do hormones affect breast tissue during the menstrual cycle?
Hormones like estrogen and progesterone stimulate changes in breast tissue, affecting its density and function. These fluctuations are particularly significant for breast development during puberty and changes throughout the normal menstrual cycle.
Why is MRI important for breast imaging in relation to hormonal changes?
MRI is highly sensitive in detecting changes in breast tissue density and structure caused by hormonal fluctuations, making it a valuable tool for screening and diagnostic purposes when conventional mammography might be less effective.
What are BRCA 1 and BRCA 2 genes and their role in cancer?
BRCA 1 and BRCA 2 are tumor suppressor genes. Mutations in these genes significantly increase the risk of developing breast and ovarian cancer because the body's ability to repair DNA damage is impaired.
How are patients with harmful BRCA gene mutations managed clinically?
Management strategies include intensive screening programs, prophylactic mastectomy (preventative removal of breast tissue), and other surgical or medical interventions to reduce cancer risk.
What are the different types of breast implant ruptures seen on MRI?
MRI can distinguish between intra-capsular ruptures (leakage within the fibrous capsule) and extra-capsular ruptures (leakage extending beyond the capsule into the surrounding tissue), each having distinct imaging appearances.
Do hormonal changes affect men and women differently regarding breast tissue?
While both develop from the same embryological tissues, estrogen drives breast development in females during puberty, whereas the male hormone testosterone does not stimulate this growth.
