Perhaps you should try some spelling variations:
decrease breast » decreases breast (Expand search), increase breast (Expand search), increased breast (Expand search)
breast abscess » brain abscess (Expand search)
pattern python » pattern action (Expand search), pattern method (Expand search)
based pattern » based battery (Expand search), based plasters (Expand search), mapped pattern (Expand search)
python based » action based (Expand search)
in decrease » in decreased (Expand search), on decrease (Expand search), pain decrease (Expand search)

You may be able to get more results by adjusting your search query.

• The words AND, OR and NOT may confuse the search; try adding quotes: "(( decrease in decrease breast abscess ) OR ( python based pattern python programming ))~".
• Adding a wildcard symbol may retrieve word variants: (( decrease in decrease breast abscess ) OR ( python based pattern python programming ))*.
