The answer is yes. The "Your Cancer Type XTRA" program was simply a renamed version of the longest cancer type treatment in the database, which was 03:21:00. So all others will be shorter. However, the user should be advised to ensure that extra programs don't make the Estimated Total Run Time longer than eight hours if a normal lifestyle must be maintained.
However, everyone is always free to add extra programs to each preset, but we strongly recommend that only healing or detox programs be considered. The bodies of cancer sufferers need adequate time to recover after each killing session. For those who choose to do this, it's best to add the extra treatment time at the start, so they should take a book to bed early and rise at their usual time the next morning.
