How to make a new variable based on 30 other variables

I have 30 variables on family history of cancer i.e. breast cancer father, breast cancer mother, breast cancer sister etc. I would like to make a new variable and give it a value of "1" if in one of my columns there is a 1. Thus: I have 30 variables with answers 1 to 3; 1 is yes, 2 is no and, 3 is unknown if one of the 30 variables is given a 1 I would like my new variable to take on the value 1. Does someone know how I can do this?
