Aluminum In Breast Tissue: A Possible Factor In The Cause Of Breast Cancer

A new study has identified a regionally-specific distribution of aluminium in breast tissue which may have implications for the cause of breast cancer. Scientists have found that the aluminium content of breast tissue and breast tissue fat was significantly higher in the outer regions of the breast, in close proximity to the area where there would be the highest density of antiperspirant. Recent research has linked breast cancer with the use of aluminium-based, underarm antiperspirants. The known, but unaccounted for, higher incidence of tumours in the upper outer quadrant of the breast seemed to support such a contention. However, the identification of a mechanism of antiperspirant-induced breast cancer has remained elusive. --Click the title of this post to read the full article from its source--

Cause of Hormone-Breast Cancer Link Found

AUSTRALIAN researchers have discovered why high levels of the female sex hormone estrogen can lead to breast cancer. Scientists at the University of Queensland studied a gene called MYB, known to promote cancer growth, and its reaction to high levels of estrogen. The study confirmed MYB becomes active when exposed to high estrogen levels, results in the journal Proceedings of the National Academy of Sciences show. --Click the title of this post to read the full article from its source--

Night Shift Work Not Linked To Increased Risk Of Cancer

Working the night shift doesn't appear to increase the risk of developing cancer, suggests the findings of a new study of Swedish workers. Recent studies – and corresponding news headlines – have found that regularly working the night shift may increase the risk of developing breast, prostate and colon cancers. Some researchers say that the connection could be due to a decrease in the production of the hormone melatonin, as some animal experiments suggest that the hormone may have anti-cancer properties. Our bodies produce their highest levels of melatonin at night, during sleep, but exposure to light at night suppresses melatonin production, said Judith Schwartzbaum, the study's lead author and an associate professor of epidemiology at Ohio State University. --Click the title of this post to read the full article from its source--

US drug firm to pay $3m in cancer suit

A Pennsylvania jury awarded $3 million on Tuesday to an Ohio woman who claimed a hormone replacement drug made by Wyeth had caused her breast cancer. The woman, Jennie Nelson, 67, of Dayton, was found to have breast cancer in 2001 after taking the drug, prempro, for five years to treat symptoms of menopause. Her lawyers said Wyeth knew for decades the drug could cause breast cancer but had failed to warn patients. More than 5,000 women have sued Wyeth over its hormone drugs Premarin and Prempro. Wyeth has won two cases and lost two cases, which have been heard in Arkansas and Philadelphia. --Click the title of this post to read the full article from its source--

Breast cancer may be sexually transmitted

A new study has revealed that breast cancer could be sexually transmitted. Emeritus Professor James Lawson of the University of New South Wales and colleagues have found the same form of the human papillomavirus (HPV) associated with cervical cancer in almost half the breast tumor samples they tested. It`s the first study of its kind in Australia, although international studies have also found cervical cancer-related HPV in breast cancer cells. He says while the evidence is far from conclusive, "it`s possible and totally worthy of investigation" to suspect that HPV could also cause breast cancer. Lawson says it`s possible that HPV is spread by sexual activity or during showers or baths, when the virus could be transferred from the genital area to the breasts via the nipple ducts. --Click the title of this post to read the full article from its source--
