Fibroadenomas are non-cancerous breast tumors that are most commonly found in women aged 15 to 35. They are made up of both glandular and fibrous tissue, giving them a firm, smooth texture. These lumps can vary in size and are usually painless, often discovered during a breast self-exam or routine screening. While fibroadenomas are generally benign, they can sometimes change in size or shape over time. Diagnosis typically involves imaging tests like ultrasound or mammography, and in some cases, a biopsy may be performed to confirm the diagnosis. Treatment options may include monitoring or surgical removal if necessary.
