OR with multiple variables!!

Hi everyone!

I guess this is easy, but I'm not too good in statistics so I need some help!!

I'm trying to evaluate a case-control study, where the most common statistical tool is the OR... but now I'm dealing with a multiple variable analysis:

This is an example: I'm analysing the relationship between the consumption of vitE and the breast cancer risk. There are different groups of consumption (variables):

Variables____Control - Case
0xweek______26 - 18
1xweek______57 - 28
3xweek______86 - 49
5xweek______37 - 29
7xweek______16 - 20

Which statistical test should I use for this analyis??? or is there another way to analyse these raw data??

I would really appreciate all your support and help!!
