Perhaps you should try some spelling variations:
decrease cancer » decreases cancer (Expand search), decrease after (Expand search), disease cancer (Expand search)
cancer objects » cancer effects (Expand search), copper objects (Expand search), concrete objects (Expand search)
and decreased » and decreases (Expand search), and increased (Expand search)
decrease loss » decrease costs (Expand search), decrease low (Expand search), decrease blood (Expand search)
loss decrease » loss decreases (Expand search), to decrease (Expand search), not decrease (Expand search)
decrease and » decreases and (Expand search), decrease in (Expand search), decrease of (Expand search)

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

• If you are trying to use Boolean operators, they must be ALL CAPS: (( decrease AND decreased OR decrease ) OR ( decrease loss decrease cancer objects ))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( decrease and decreased OR decrease ) OR ( decrease loss decrease cancer objects ))~".
• Adding a wildcard symbol may retrieve word variants: (( decrease and decreased OR decrease ) OR ( decrease loss decrease cancer objects ))*.
