Does 'grep' update a file's access date/time?

I've got a job that finds and removes trace files based upon an access time of more than seven days (I've also tried a modify date).

Code:
find TABC*[0-9][0-9] -atime +7 -exec rm +

Code:
find TABC*[0-9][0-9] -mtime +7 -exec rm +

Whether I use -atime or -mtime, the process seems to work sporadically. Sometimes it removes the files as expected. Other times it won't "find" them at all. These files contain lots of data that I frequently grep/awk/head/tail through, so I am wondering if any of those commands would update my file's access date/time values, and thus render my find inaccurate.

Thank you!
