Silenium and vitamin E could increase the risk of prostate cancer

A multi-centre study led by the Fred Hutchinson Cancer Research Center in Seattle, Washington, has found that high-dose supplementation with both the trace element selenium and vitamin E increase the risk of high-grade prostate cancer. But importantly, this risk depends upon a man’s selenium status before taking the supplements.  

Traces of a breast cancer drug found in supplement

Researchers have found the breast cancer drug tamoxifen in samples of a widely-available bodybuilding dietary supplement.

Little-studied chemical compound halts a common cancer process

Johns Hopkins scientists say a previously known but little-studied chemical compound targets and shuts down a common cancer process. In studies of laboratory-grown human tumour cell lines, the drug disrupted tumour cell division and prevented growth of advanced cancer cells.  

Simplified test for diagnosis and stage of cervical cancer

Researchers at the University of Louisville School of Medicine in the USA have confirmed that using a plasma thermogram — the heat profile from a person’s blood —  can serve as an indicator for the presence or absence of cervical cancer, including the stage of cancer.  

Ireland’s high rate of alcohol is related to cancer deaths

The proportion of alcohol- related deaths from cancer in Ireland is higher than the European average, according to a new study, which calculated Ireland’s cancer incidence and mortality rates attributable to alcohol over a 10-year period between 2001 and 2010.  

Comparison of cancer survival rates

Adults in the UK and Ireland continue to have shorter survival than the European average for many common cancers, particularly colon, (52 per cent vs 57 per cent) ovary (31 per cent vs 38 per cent) and kidney, (48 per cent vs 61 per cent) but have about average survival rates for rectum, breast, prostate, […]

Increased risk of breast cancer in spite of negative BRCA2 test

Women who are members of families with BRCA2 mutations but who test negative for the family-specific BRCA2 mutations are still at greater risk of developing breast cancer compared with women in the general population, according to a study published in Cancer Epidemiology, Biomarkers and Prevention, a journal of the American Association for Cancer Research.

Early stage breast cancer diagnosis by blood samples

What could some day be the first blood test for the early detection of breast cancer was shown in preliminary studies to identify successfully the presence of breast cancer cells from serum biomarkers, say the Houston Methodist Research Institute scientists who are developing the technology.

One-stop radiotherapy for breast cancer

Two studies, published in The Lancet and The Lancet Oncology, show that for some women undergoing surgery for early breast cancer, targeted radiotherapy delivered during surgery could offer a viable alternative to current procedures, which require women to attend daily radiotherapy sessions for weeks after surgery.

Keeping on top of Irish skin cancer trends

The National Cancer Registry Ireland outlines the incidence and trends in non-melanoma skin cancer, including male-to-female ratios and differing rates in terms of social deprivation. Non-melanoma skin cancer Case numbers and histological types Between 1994 and 2011, an average of 6,899 cases of invasive skin cancer were diagnosed per year in Ireland. Malignant melanoma accounted […]
