Chrysotile Asbestos Exposure linked to Lung Malignancy

chrysotile asbestos
Asbestos was once widely used worldwide. With the realization of health hazards associated with asbestos exposure more than 52 countries have either banned or restricted the use of asbestos.  Unfortunately the mining and use of asbestos is continuing in developing countries like India and China. In India alone, the use of asbestos has doubled over the past decade and more than 100000 workers are exposed to this mineral. Asbestos, chemically fibrous hydrated magnesium silicate occurs in two...

Drinking Red Wine in Moderation may reduce the Risk of Breast Cancer

Alcohol consumption is a known risk factor for development of breast cancer. But, on the other hand, studies have shown that aromatase inhibitors prevent the conversion of androgens into estrogens and thus, have a protective action against breast cancer. These aromatase inhibitors are present in grapes and red wine, though they are absent in white wine. Therefore, it was natural for scientists to study whether the consumption of red wine, by virtue of aromatase inhibitors present in it, exerts...

Increased Consumption of Milk Linked to Risk of Prostate Cancer

According to Dr. Johanna Torfadottir, a nutrition scientist from the University of Iceland and the lead author of the study, Icelanders who have a history of drinking a lot of milk while they were teenagers, are three times more likely to develop advanced prostate cancer compared to...

Poorer Prognosis of Breast Cancer in Obese HER-2 Positive Patients

According to a new study presented at the 2011 CTRC- AACR San Antonio Breast Cancer Symposium, the researchers have found that obese patients with HER-2 breast cancer have a poorer prognosis compared to women who are of normal weight or are slightly overweight. HER-2 or Human Epidermal Growth Factor Receptor 2 positive status accounts for one third of all cases of breast cancer. HER-2 protein causes a spurt in the growth of cancer cells. The study conducted by researchers from the Mayo Clinic,...

Higher Incidence of Blood Clots with Hormone Therapy for Prostate Cancer

Of late, hormonal therapy for prostate cancer, also called as androgen deprivation therapy (ADT), is being used in an increasing number of patients. This, however, is a rather disturbing trend, and may even prove dangerous, as a new study has found out. The study, published in the online issue of the journal Cancer on  November 9, 2011 has found that ADT is associated with a higher incidence of blood clots in the vessels, with 25% of them landing in the hospital with some complication. When...
