Women’s Health Weekly Review: July 6 - July 12

Breast Cancer

Breast asymmetry after cancer treatment affects quality of life, U-M study finds

Young women’s breast cancers tend to be more aggressive and less responsive to treatment than the cancers that arise in older women

The gene HER2 that is overexpressed in 20% of breast cancers increases the number of cancer stem cells, the cells that fuel a tumor’s growth and spread, according to a new study from the University of Michigan Comprehensive Cancer Center. Herceptin - a drug used to treat HER2-positive breast cancer - targets and destroys the cancer stem cells.

According to a report in the Proceedings of the National Academy of Sciences breast cancer cells secrete a common inflammatory protein, IL-8. When the the protein was blocked with an antibody, it completely stopped the spread of breast cancer to the lungs (this was in mice). They also found that the protein produced by the gene DACH1 blocks the production of IL-8 - DACH1 is commonly missing or inactive in invasive breast cancer

Pregnancy

Children born from frozen embryos weigh more and do better than those born after fresh transfer

IVF does not increase risk of developmental disorders in children

Other

In a study published in the journal Biological Psychiatry data is presented that suggests a particular variant of a gene involved in endorphin metabolism may result in women with this variant to be more susceptible to alcoholism.

Early-life nutrition may be associated with adult intellectual functioning

This is a wonderful list of articles!

I work for a Non-Profit called the International Dark-Sky Association and we deal with the effects of artificial lighting on human health. Research shows that artificial night lighting can cause the body not to produce enough melatonin, which prevents breast cancer. Dr. David Blask did lab research (those poor rats!) on the issue. When he found that rats who had artificial light during their sleeping hours had higher rates of cancer and lower melatonin, some lighting tests were done on women. They basically lit the room up at night and found that women had decreased melatonin levels. Another study done in India checked women working the graveyard shift and there was a much higher rate of breast cancer amongst those women. Out of all of this, we have no idea how much artificial light it takes to decrease the melatonin enough to allow cancer growth, but it’s definitely an interesting topic! Haha I am probably sounding crazy now.
