My MCV IS 101.8. My MCV IS 33.4. My MPV

My MCV IS 101.8. My MCV IS 33.4. My MPV IS 7.4. I have been doing B12 shots every 2-3 weeks for about 15 years, because my body was not producing enough and also was not absorbing it orally. I am 67 years old and been in excellent health. I'm careful nutritionally and I work out in walk during the week. I drink wine about 3 to 4 nights a week. I was told that since I am petite that wine might be causing this problem. Also that these numbers lead to leukemia. Should I not have alcohol at all? Also could these numbers also indicative of something to do with the B12?
