Exciting new immunotherapy treatment !

Test tube lab

The holy grail of cancer treatment is design a drug that is highly lethal to cancerous tissue but completely spares the normal tissues.

Scientists at Cardiff University have discovered immune cells which could provide such a clever treatment.

It is still early days. The principle has been proven in lab. But to be a useful treatment that can be used in cancer patients, it is still far off.

This particular novel form of immunotherapy using T cells is still in early stages and so many hurdles have to be overcome before this discovery could be employed in cancer treatment.

Nevertheless, it has certainly excited many researchers in the field of cancer and the paper has been published by a premier scientific journal.

Does alcohol increase of breast cancer?

Yes, Alcohol does substantially increase the risk of Breast cancer.

Very few people seem to be aware of the risks.

Previously it was thought that heavy drinking is responsible for harmful cancer effects.

But studies from U.K and U.S.A have subsequently shown that even light to moderate drinking can increase the risk of breast cancer.

A very large study involving more than 1,250,000 middle-aged women in the United Kingdom ( enrolled in the Million Women Study) showed that “Low to moderate alcohol consumption” in women increases the risk of breast cancer and certain other cancers.

In a study involving more than 88,000 women from United States, also showed that light to moderate drinking increases the risk of breast cancer.

So keep counting the alcohol units during the festive time.

Can milk cause cancer?

A vegan group’s recent advertisement claimed that “cow’s milk contains 35 hormones, including oestrogen … some of these are linked to cancer”.

Advertising Standards Authority (ASA) in U.K banned the vegan group’s advert  as it found the groups claims misleading.

Does the evidence stack up?

First of all, I have to emphasize that “Human Mothers milk” is the best nutrition a new born baby can have…even though it might have various natural hormones.

But “mass produced diary milk” is a different matter.

A large observational study from ” Central Sweden”  found that “High milk intake was associated with higher risk of death and higher fracture incidence in women”. The paper was published in the prestigious BMJ journal in 2014. I suspect the substances used in mass production of diary milk might be the culprit rather than natural milk itself.

So the jury is out on this question. In the mean time, moderation is the key as Cows’ milk does contain many beneficial substances.  Switching to sugary, fizzy drinks or other artifically produed milk alternatives is not sensible either.
