Overview
If benign breast lumps left untreated, those proved to be benign both by clinical examination and cytological diagnosis, do not become malignant and 68% of benign breast lumps resolve by time mostly after 2 years [1].
Benign breast lumps should approved to be benign both clinically and cytologicaly. Because some of breast lumps which thought to be benign ones can turn to be malignant by cytological results [1]
breast lumps which approved to be benign both clinically and cytologicaly in women under 35 years can resolve over time if do not excised [1]
Natural History, Complications, and Prognosis
Natural History
- Natural history of breast lumps did not well-studied and little is known about it [1]
- Regarding to prevent missed malignancy and patient's reassurance, benign breast lumps are excised
- The symptoms of benign breast lumps,especially fibroadenomas, usually develop in the second and third decade of life, and discrete breast lumps considered to be benign by clinical examination
- If left untreated, 68% of patients with benign breast lumps may regress over 2 years
- The histological reason for resolution of breast lumps is associated with the fact that lumps merge into stroma and hyalinization [2]
Complications
- Common complications of breast lumps include
Prognosis
The relative risk (RR)of following breast cancer in different types of breast lumps[5][6][7]
- Non-proliferative breast lesions have RR 1.2-1.4
- Proliferative diseases (PD) have RR 1.7-2.1
- Proliferative diseases (PD)with atypia hve RR more than 4 for breast cancer
- PD and PD with atypia may be considered as early stages of breast cancers
- Development risk to breast cancer from benign breast disease associated with 20 years follow-up
