I'm trying to compare categorical data between 4 groups

i.e :

smoking history (yes or no) between 4 groups of cancer staging (stage I to IV)

Some of the cells has 0 value in it (every person in stage I never smoke, while stage II has 5 smokers, etc)

Can I still use Chi-squared test for this hypotheses? I understand that you can't have 0 value in one of the cells for Chi-squared test.

I can't use Fisher test also because it is not a 2x2 table.

Can anyone show me the appropriate test?

What i'm trying to find out is there a difference in smoking history between persons with different stages of cancer.

Thank you
