Slave has more data than Master?

Hi all,

I have one Master and one Slave, tables are MyISAM in them. there are about 30 new data inserted to the Master every minute. The replication between them seems work well, but I find that Slave has more data than Master within some time period.

I am sure the data before the replication is the same on the Master and slave.
I am also sure that these external data in Slave must be from the Master, and they are not some random data, they are reasonable like other data. So I do not know how this data can be in the Slave, but not in the Master. Could someone tell me?

Maybe, I assume the potential reason is: some data do not insert to the Master successfully, but relevant logs have been written successfully into binary logs. Therefore, slave has more data, because the replication is based on these binary logs. Is it possible?
