A tumour formed of mixed fibrous and glandular tissue, typically occurring as a benign growth in the breast.Fibroadenomas are solid, noncancerous breast tumors that occur most often in adolescent girls and women under the age of 30. A fibroadenoma might feel like a marble in your breast, moving easily under your skin when touched.
Symptoms: Fibroadenomas are solid breast lumps or masses that usually are: Round with distinct borders . Easily moved . Firm or rubbery . Painless.
Diagnosis: After a physical exam, one or both of the following tests are usually done: Breast ultrasound Mammogram A biopsy may be done to get a definite diagnosis. Different types of biopsies include: Open Stereotatic Ultrasound.
Treament: If a biopsy shows that the lump is a fibroadenoma, the lump may be left in place or removed. Reasons to have it removed include: Abnormal biopsy results. Pain or other symptoms occur. Worry or concern about cancer. If the lump is not removed, your health care provider will watch to see if it changes or grows. This may be done using Mammogram Physical examination Ultrasound.
Epidemology: After exclusion of 57 synchronous breast neoplasms, a total of 17 cases of breast cancer were observed vs. 10.9 expected (standardised incidence ratio, SIR, 1.6; 90% confidence interval: 1.1-2.1). The SIR was similar in the short term (3.5 years) and in the medium-long term (>5 years) following diagnosis of fibroadenoma. The cumulative risk of invasive breast cancer was 0.7% after 5 years and 2.2% after 12 years following diagnosis of fibroadenoma. This is not negligible on account of the young age of our cohort.
