Why is it not advisable to write DVDs in multisession? will they be spoilt?

Question

Ihave written a dvd n mutisesion and my friend says it will get spoilt just with minor scratches.Really? is it just that i have to kep it safe till i finalise it, without scratches and once finalised will it be no longer vulnerable? Or is it that once you write it inmultisession it is permenantly vulnerable?
