Skin Flaps Deliver Cancer-fighting Therapy, Study Reveals
Using gene therapy, plastic surgeons have delivered cancer fighting proteins through skin flaps placed on cancerous tumors on rats with a 79 percent reduction in tumor volume, according to a study in Plastic and Reconstructive Surgery.

6-month Follow-up Diagnostic Mammograms Recommended For Women With Probably Benign Lesions, Study Suggests
Radiologists can, with confidence, recommend a six-month follow-up diagnostic mammogram rather than an immediate biopsy for patients with "probably benign" breast lesions, a new study emphasizes.

Breast Cancer Tumors Grow Faster In Younger Women
A new approach to estimating tumor growth has been developed based on breast screening results from almost 400,000 women. This new model can also estimate the proportion of breast cancers which are detected at screening (screen test sensitivity). It provides a new approach to simultaneously estimating the growth rate of breast cancer and the ability of mammography screening to detect tumors.

Common Herbicide Disrupts Human Hormone Activity In Cell Studies
A common weedkiller in the US, already suspected of causing sexual abnormalities in frogs and fish, has now been found to alter hormonal signaling in human cells, scientists report. The herbicide atrazine is the second most widely used weedkiller in the U.S., applied to corn and sorghum fields throughout the Midwest and also spread on suburban lawns and gardens. It was banned in Europe after studies linked the chemical to endocrine disruptions in fish and amphibians.

Previously Unseen Switch Regulates Breast Cancer Response To Estrogen
A tiny modification called methylation on estrogen receptors prolongs the life of these growth-driving molecules in breast cancer cells. Most breast cancers contain estrogen receptors, which enable them to grow in the presence of the hormone estrogen. Their presence can determine whether tumors will respond to the estrogen-blocking drug tamoxifen. The finding will help researchers sort out how mutations change the estrogen receptor's function and allow some breast cancers to resist tamoxifen.
