Cancellation removes magical properties of items and monsters it hits. See the main article for the full list, but when zapped at yourself most notably it will make all items uncursed, remove their enchantments and/or charges, turn most potions to water, and blank any scrolls or spellbooks. It can be used to get rid of cursed gear, by dropping any items which would be adversely affected and zapping yourself. Generally, a spellbook of remove curse is preferable for this task, though, since it does not require dropping your items and will not remove enchantment from weapons and armor.
When zapped at monsters, cancellation can remove certain types of special attacks. This must pass a monster MR check, though. This makes it nearly useless against many of the monsters one would want to use cancellation against, such as liches.
Overall, the spell is of questionable utility: it is very difficult to cast, finger of death costs the same while killing most monsters outright, and a single wand of cancellation is usually enough for all of one's cancellation needs.
