Over-exposure to Plasticizers Causes Breast Cancer: Study

Women who are exposed to plasticizers are 1.9 times more likely to develop breast cancer, according to a study.

Plasticizers or dispersants are compounds added to plastic products to improve flexibility and durability. These substances include polyvinyl chloride (PVC), Phthalate, adipates, trimelliates and other synthetic chemicals. Researchers at the Academia Sinica, National Health Research Institute and National Taiwan University Hospital found prolonged exposure to plasticizers can increase risk of breast cancer. Their study examined health statuses of 12,000 women in Taiwan who were followed for certain period of time to note their susceptibility for breast cancer, reports the Focus Taiwan.

Nearly 128 women were diagnosed with the disease and their urine samples were compared with that of 251 healthy female participants.  It was observed that women who were frequently exposed to plasticizers had almost two-fold higher chances of developing the disease compared to subjects from the control group. The risk rate rose up to 3.4 times especially for those with poor metabolism.

The study explained when plasticizers are ingested they disturb hormonal balance and increase oxidation during metabolism leading to genetic alterations that trigger formation of cancerous cells and tumors in the breast.  In many cases, the chemicals release compounds that slow body's metabolic rate through kidneys within 24 to 48 hours after exposure. Drinking water in sufficient quantities helps flush out these toxins from the body before reacting with the hormones.

Plasticizers are blended with plastic materials, concrete, clay and other substances to make tubes, hoses, wall coverings, gaskets, belts, wires, toys, shower curtains and cables. The authors urge women to limit their daily exposure to harmful chemicals and plastic additives, drink enough water and get regular screenings for cancer to prevent the disease and mortality.

Breast cancer rate in Taiwan for women aged above 50 is similar to the disease incidence in many countries across Europe and U.S, reports the China Post.
