Classification

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]
  • [Group4]

OR

[Disease name] may be classified into [large number > 6] subtypes based on:

  • [Classification method 1]
  • [Classification method 2]
  • [Classification method 3]

[Disease name] may be classified into several subtypes based on:

  • [Classification method 1]
  • [Classification method 2]
  • [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].
