Spring is around the corner and we welcome the revitalization of budding leaves, flowers and grass. During this time of year we also encounter exposure to toxic pesticides and weed killers which are applied for lawn and garden care and insect control. Over the past decades, research has shown that certain garden pesticides may mimic the hormone estrogen and increase breast cancer risk.
Study record managers: refer to the Data Element Definitions if submitting registration or results information. This study will collect information on the height and weight of women who participated in a study in Triana, Alabama, on the risk of breast cancer and benign breast disease in relation to environmental exposure to the pesticide DDT and similar chemicals. This additional information is needed to calculate the participants' body mass index BMIwhich is required for completing analysis of the data.
Pesticides and herbicides are used to control insects and unwanted plants in agricultural fields. The chemicals in pesticides and herbicides can be inhaled or absorbed through the skin by those who work or live in close vicinity to the fields, and may also be consumed if residues remain on produce. Chlordane is a pesticide, and 2,4,5-trichlorophenoxy propionic acid 2,4,5-TP is an herbicide.
Nearly 1. While treatments and survival rates continue to improve, the incidence of some cancers are on the rise — including childhood cancers, leukemia and testicular cancer. We're experiencing a cancer epidemic, and evidence is growing ever stronger that pesticide exposure is a key contributor to this disturbing trend.
By Gail Vines. Chemicals should be screened for their ability to mimic the hormone oestrogen before they are released into the environment, she says. Now some scientists are claiming that extra doses of oestrogen-like compounds in the environment may increase the quantities of hormone some women receive to dangerous levels.

A study that found a sharply higher rate of breast cancer in women exposed to the pesticide DDT while in the womb has drawn renewed attention to the relationship between pesticide and herbicide exposure and cancer. The studypublished earlier this year, tracked nearly 15, mothers, daughters, and granddaughters living in the San Francisco Bay area. Researchers measured DDT levels in the mothers of women who were diagnosed with breast cancer by age 52, and in the mothers of women without breast cancer.
All rights reserved. The cause of most breast cancer is unknown, but a new study found that women exposed in the womb to the now banned pesticide DDT have a quadrupled risk of developing the disease. Genes account for only 5 to 10 percent of breast cancer cases.
