I don't know if you should worry so much about the dairy issue. Most of the research I found on cancer and dairy products had to do mostly with the amount of dairy fat in the product. I think the other (saturated) animal fat's would propose a greater risk. Nancy's organic, low-fat cottage cheese is available and there seems to be a Science as to the success of the combo flax and cottage cheese combination. I understand that plain yogurt will give similar results but you need to use at least 3 cups of yogurt per day with 4 tablespoons of the oil if really ill. I just started using the cottage cheese and oil but have noticed that it may be too high in protein for me, (a cup a day), because my kidney hurts. I did not have this problem with non-fat organic yogurt, and noticed that my energy is much better after only 3 days of use. Read Cliff Beckwith's info on the web. He cured himself of prostrate cancer with the cc. and fo. combo, and has a long list of following others who did not do so well that changed the protocal or didn't eat enough of it or went off it. The info from Budwig says that it takes at least three months to see a reduction in tumors. Hope this helps.
