PENANG: Pregnant women exposed to common household pesticides are
putting their unborn babies at risk of developing breast cancer later
on in life.

Even the slightest exposure to chemicals used in gardening and on
insects and mosquitoes could cause dormant cancer cells to develop,
Pesticide Action Network (PAN) Asia Pacific scientist and PAN
Aotearoa/New Zealand coordinator Dr Meriel Watts said at the PAN 25th
Anniversary Conference.

Watts, who launched her book Pesticides and Breast Cancer: A Wake Up
Call at the event Friday, said the book, which was a collation of
scientific evidence spanning more than 30 years, provided compelling
argument for preventing the exposure of women and girls to many of
today's commonly used pesticides.

"The book takes a very comprehensive look at 98 pesticides—including
insecticides, herbicides and fungicides with the potential to cause
breast cancer.

"One of the critical aspects is to see if these pesticides promote
breast cancer cell growth especially at the foetal stage.

"Breast cancer is by far the most common cause of cancer in women
throughout the world. The disease is also escalating in the Asia
Pacific region. It is time for systemic change in our attitude to
pesticides," she said, adding that the book which took three years to
complete, was aimed at creating greater awareness about the dangers
of pesticides not just for women who work in the fields, but also for
expecting mothers and young girls.
