This guide to breast health will help you understand breast changes and how to keep your breasts healthy and beautiful.

From puberty through the rest of our lives, our feelings about our breasts are deeply personal.

Yet, most of us lack a true understanding of our breasts. Even as we associate our breasts with femininity, sexiness and motherhood, we may not know what determines the size of our breasts, what changes take place during the menstrual cycle or what happens to our breasts during pregnancy, breastfeeding and menopause.

Having this knowledge is even more important now that the yearly "well woman" visit covered by insurance gives women the chance to discuss their breast health and important screening tests with their care team. At the same time, women need evidence-based information to help them make informed decisions about breast cancer screening, genetic testing, aesthetic breast procedures, breast cancer and reconstruction after breast cancer.

Until now, it was not easy for women to search the web for answers to their breast-related questions. This is why HealthyWomen created this online guide, which explains women's breasts from the inside out and gives you up-to-date information on all aspects of breast health.

Developed with help from leading breast health associations and medical societies, the guide features research-based facts and figures carefully checked by a team of women's health experts for accuracy. It also gives you links to helpful resources from trusted sources.

Most importantly, the guide is meant to be your one-stop information hub on healthy breasts. This means answering your questions on:

  • Breast size, shapes, lumps and density
  • What happens to a woman's breasts at different life stages
  • The link between diet, exercise and healthy breasts
  • The importance of knowing your breast density
  • Various breast screening methods, including mammography
  • The use of breast risk assessments and genetic testing
  • The different types of surgery to lift, increase or reduce the size of your breasts
  • The science-based facts on breast implants
  • The basics on various types of breast cancer
  • What it means to have hormone positive or triple negative breast cancer
  • What it means to have metastatic breast cancer
  • Breast reconstruction after mastectomy, including surgical options and insurance coverage

Because our breasts factor into so many aspects of our lives, it's time to understand what is happening with our breasts and learn how to keep them beautiful and healthy. The answers are all here.
