I Am 70 Years Old And Have Always Enjoyed Good

I am 70 years old and have always enjoyed good health. I am still working however in a very non stressful environment. I was vaccinated several years ago for shingles, and to my surprise, and disappointment, developed shingles about 5 days ago. At best it is a moderate case, though it does seem to be slowly spreading. Since this virus seems opportunistic to a lower level of immunity, is there any evidence of a correlation of shingles and cancer.
