Overview
There is no established system for the classification of [disease name].
OR
[Disease name] may be classified according to [classification method] into [number] subtypes/groups: [group1], [group2], [group3], and [group4].
OR
[Disease name] may be classified into [large number > 6] subtypes based on [classification method 1], [classification method 2], and [classification method 3]. [Disease name] may be classified into several subtypes based on [classification method 1], [classification method 2], and [classification method 3].
OR
Based on the duration of symptoms, [disease name] may be classified as either acute or chronic.
OR
If the staging system involves specific and characteristic findings and features: According to the [staging system + reference], there are [number] stages of [malignancy name] based on the [finding1], [finding2], and [finding3]. Each stage is assigned a [letter/number1] and a [letter/number2] that designate the [feature1] and [feature2].
OR
The staging of [malignancy name] is based on the [staging system].
OR
There is no established system for the staging of [malignancy name].
Classification
Classification of breast lumps based on epithelial hyperplasia[1]
- Approximately 65% of all benign breast disease considered as nonproliferative (NP)with relative cancer risk of 1.2, 1.4 times:
- Simple cyst
- Fibrosis
- Fibroadenoma (simple)
- Columnar alteration (Simple)
- Apocrine metaplasia (simple)
- Mild ductal hyperplasia
- Approximately 30% of total are classified as (PD) with relative cancer risk of 1.7, 2.1 times
- Usual ductal hyperplasia
- Sclerosing adenosis
- Columnar hyperplasia
- papilloma
- Radical scar
- Approximately 5% to 8% of the rest regarded to PD with atypia with relative cancer risk more than 4 times
- Atypical lobar hyperplasia
- Lobular carcinoma in situ
- Atypical ductal hyperplasia
- Unclear risk
