Problem with high Maximum tombstones per slice?

I'm seeing the stats below for one of my tables running nodetool cfstats

Maximum tombstones per slice (last five minutes): 23571

Per the Datastax doc:

Maximum number of tombstones scanned by single key queries during the last five minutes

All my other tables have low numbers like 1 or 2. Should I be worried? Should I try to lower the tombstone creation?

Tombstones can impact on read performance if they are residing in frequently used tables. you should re-work on data modelling part. Also. you can lower the value of gc_grace_seconds so that tombstones clear fast instead of waiting default value 10 days.
