No cancer link
LONDON – A large long-term study on the use of the big-selling weedkiller glyphosate by agricultural workers in the United States has found no firm link between exposure to the pesticide and cancer, scientists said on Thursday.
Published in the Journal of the National Cancer Institute (JNCI), the study found there was no association between glyphosate, the main ingredient in Monsanto’s popular herbicide RoundUp, “and any solid tumors or lymphoid malignancies overall, including non-Hogkin Lymphoma (NHL) and its subtypes”.
MANY women who follow initial breast cancer treatment with five years of hormone therapy to keep tumours at bay may still experience new malignancies up to two decades after their diagnosis, a study suggests.
Researchers examined data from 88 clinical trials involving 62,923 women with estrogen receptor (ER)-positive tumours. After treating ER-positive tumors with chemotherapy, radiation or surgery, women typically get five years of follow-up therapy with daily hormone-based pills — either tamoxifen or aromatase inhibitors.
