On cow's milk and general health
First of all, there are huge differences in the quality of milk. While organic raw milk from grass-fed (pastured) cows has many ardent promoters and appears to be health-promoting (such as by providing an excellent source of bioavailable minerals and trace elements), the ubiquitous pasteurized/homogenised cows' milk variety may well actually be deleterious to the human body.
Among a number of reasons, the calcium contained in pasteurized milk is difficult to absorb (it may not be a coincidence that the countries with the highest pasteurized dairy consumption have the highest incidence of osteoporosis). For a more or less biased (but in my view very much worth a visit) presentation of the health-related drawbacks of milk, see www.nomilk.com and www.notmilk.com.
Is there any link of cow's milk to cancer?
While variious research reports have linked cow's milk to breast and ovarian cancer as well as prostate and colon cancer, a recent large-scale study published in Nutrition Journal in October 2016) found a valid association only for prostate cancer. Analyzing the records of more than three quarters of a million patients, the only significant association found was between whole milk consumption and prostate cancer mortality. While (overall) dairy intake showed no significant impact on elevated cancer mortality risk, low dairy intake did reduce the risk "based on the non-linear model".

In partial contradiction of the findings of the above meta-analysis, other researchers found that ”IGF-1 is known to stimulate the growth of both normal and cancerous cells. In 1990 researchers at Stanford University reported that IGF-1 promotes the growth of prostate cells. This was followed by the discovery that IGF-1 accelerates the growth of breast cancer cells. In 1995 researchers at the National Institutes of Health reported that IGF-1 plays a central role in the progression of many childhood cancers and in the growth of tumours in breast cancer, small cell lung cancer, melanoma, and cancers of the pancreas and prostate. In September 1997 an international team of researchers reported the first epidemiological evidence that high IGF-1 concentrations are closely linked to an increased risk of prostate cancer. Other researchers provided evidence of IGF-1's link to breast and colon cancers.”
