What is the most common type of breast growth in individuals aged 15-35?

The most common type of breast growth in individuals aged 15-35 is a fibroadenoma. Fibroadenomas are solid, non-cancerous tumors made up of both glandular and stromal (connective) tissues. They usually present as painless, firm lumps in the breast and can be easily moved when pressed. The prevalence of fibroadenomas is particularly high in younger women, making them one of the most frequently encountered benign breast lesions in this age group.

Understanding why fibroadenomas are more common during this period of life involves recognizing the hormonal changes that occur during adolescence and early adulthood, which influence breast tissue development. These growths can occur in both unilateral and bilateral forms, affecting a significant number of women in this demographic.

While cysts, intraductal papillomas, and fibrocystic changes are also conditions that may arise in breast tissue, they do not have the same prevalence in the 15-35 age range as fibroadenomas do. For instance, cysts may be more common in women who are slightly older or premenopausal. In contrast, fibrocystic changes are associated with hormonal fluctuations and can present at various ages but are more characteristic of the menstrual cycle rather than a specific age
