IUD may increase breast cancer risk in certain women.

A new study has found that a specific intrauterine device (IUD) is associated with a greater risk of breast cancer, but not endometrial, ovarian, pancreatic, or lung cancers. The researchers examined data from over 93,000 women in Finland who had used the LNG-IUS to treat their menorrhagia. The women ranged in age from 30 to 49 years. The breast cancer rate for the group using the system for menorrhagia control was approximately 19% higher than the breast cancer rate for the general population. No increase in uterine cancer or ovarian, pancreatic, or lung cancers was seen with IUD use. Other factors, beyond the IUD use, could also be at play, especially factors related to the menorrhagia, so a direct link between IUD use and cancer will need to be proven by additional research.

Protein pushes breast cancer cells to metastasize.

‘Master-regulator’ protein which pushes breast cancer cells to metastasize is identified. Unexpected links to Alzheimer’s disease and Huntington’s disease also seen. Using an innovative tool that captures heretofore hidden ways that cells are regulated, scientists at Rockefeller University have identified a protein that makes breast cancer cells more likely to metastasize. What’s more, the protein appears to trigger cancer’s spread in part by blocking two other proteins that are normally linked to neurodegeneration, a finding that suggests these two disease processes could have unexpected ties.

Brain tumour invasion along blood vessels may lead to new cancer treatments.

NIH-funded researchers map brain tumour cells disrupting the blood-brain barrier, offering potential avenues for therapy. Invading glioblastoma cells may hijack cerebral blood vessels during early stages of disease progression and damage the brain’s protective barrier, a study in mice indicates. This finding could ultimately lead to new ways to bring about the death of the tumour, as therapies may be able to reach these deadly cells at an earlier time point than was previously thought possible.
