Perhaps you should try some spelling variations:
decrease lesions » disease lesions (Expand search), decreased response (Expand search), decrease adhesion (Expand search)
lesions decrease » response decrease (Expand search), lesions case (Expand search)
of reprocessing » of geoprocessing (Expand search), of processing (Expand search), and reprocessing (Expand search)
decrease risk » decreased risk (Expand search), increase risk (Expand search), decrease in (Expand search)
risk decrease » risk decreases (Expand search), risk increase (Expand search), break decrease (Expand search)
decrease of » decrease in (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 lesions decrease of reprocessing ) OR ( decrease NOT decrease risk decrease ))~".
• Adding a wildcard symbol may retrieve word variants: (( decrease lesions decrease of reprocessing ) OR ( decrease NOT decrease risk decrease ))*.
