Drinking Milk in Childhood Cuts Risks of Cancer (?)

That may be true but the report below is a weak basis for saying so. It is retrospective self-report of unknown reliability and may simply show that people believe milk to be good for them

Good habits of childhood, no matter how resentful they were always end up paying well, it seems. According to a new study, the people who took part in the milk drinking programme during their schooling are at the lower risk of cancer today.

A survey published in the American Journal of Epidemiology recruited around 1000 people, which also included patients with pre-existing bowel cancer. The questionnaire prepared asked them about their milk drinking habits, summing up the total quantity they had per week.

Associate Professor Dr. Brian Cox and Dr. Mary Jane Snyed, who led the study found that there was 30% reduced risk of bowel cancer for those who took drank milk regularly. The results were more significant for those who were the biggest milk drinkers. They reported of being at 38% lowered cancer risk.

The findings of the study are looked up with the great expectations for New Zealand, which has currently the highest number of Cancer cases. It is estimated that approximately 3000 people are diagnosed with the disease, out of which 1200 people die every year.

The researchers claim that the presence of calcium in the milk accounts for healthier bones thereby also contributing towards the negative effect on the growth of bowel adenomas.


Drug may guard against lung cancer death

A very poorly controlled study. How did the women getting and not getting the drug differ?

Tamoxifen, a drug commonly used to treat breast cancer, may also help reduce the risk of death from lung cancer, says a study published in the US peer-reviewed journal Cancer today.

Tamoxifen works by blocking oestrogen. Previous studies have shown that women undergoing hormone replacement therapy to boost oestrogen during menopause showed an increased risk of dying from lung cancer.

Based on the hypothesis that blocking oestrogen might also cut lung cancer death risk, researchers examined data from 6655 women diagnosed with breast cancer between 1980 and 2003 in Switzerland's Geneva Cancer Registry. Close to half of those women, 3066 (46 per cent), were given anti-oestrogen drugs.

The registry's Elisabetta Rapiti, lead author of the study in Cancer, followed all those subjects until December 2007 and looked at how many developed lung cancer and how many died from lung cancer. Rapiti found that among those taking anti-oestrogen drugs, there were 87 per cent fewer deaths from lung cancer when compared with the general population.

When she looked simply at how many women in the study were diagnosed with lung cancer, she found no significant difference between those taking anti-oestrogen therapy and those who were not. "Our results support the hypothesis that there is a hormonal influence on lung cancer which has been suggested by findings such as the presence of oestrogen and progesterone receptors in a substantial proportion of lung cancers," said Rapiti.

"If prospective studies confirm our results and find that anti-oestrogen agents improve lung cancer outcomes, this could have substantial implications for clinical practice," she added.
