- What are the most common types of childhood cancer?Among the 12 major types of childhood cancers, leukemias (blood cell cancers) and cancers of the brain and central nervous system account for more than half of the new cases. About one-third of childhood cancers are leukemias. The most common type of leukemia in children is acute lymphoblastic leukemia. The most common solid tumors are brain tumors (e.g., gliomas and medulloblastomas), with other solid tumors (e.g., neuroblastomas, Wilms tumors, and sarcomas such as rhabdomyosarcoma and osteosarcoma) being less common.
- How many children are diagnosed with cancer in the United States annually?In the United States in 2007, approximately 10,400 children under age 15 were diagnosed with cancer and about 1,545 children will die from the disease (1). Although this makes cancer the leading cause of death by disease among U.S. children 1 to 14 years of age, cancer is still relatively rare in this age group. On average, 1 to 2 children develop the disease each year for every 10,000 children in the United States (2). (more…)

Many agricultural pesticides – including some previously untested and commonly found in food – disrupt male hormones, according to new tests conducted by British scientists.The scientists strongly recommended that all pesticides in use today be screened to check if they block testosterone and other androgens, the hormones critical to a healthy reproductive system for men and boys.“Our results indicate that systematic testing for anti-androgenic activity of currently used pesticides is urgently required,” wrote the scientists from University of London’s Centre for Toxicology, led by Professor Andreas Kortenkamp. Thirty out of 37 widely used pesticides tested by the group blocked or mimicked male hormones. Sixteen of the 30 had no known hormonal activity until now, while there was some previous evidence for the other 14, according to the study, published online last Thursday in the scientific journal Environmental Health Perspectives.

Next week, EPA’s science advisors will wrap up a 2-year review of the latest studies on the health and environmental harms of atrazine. Administrator Lisa Jackson needs to know that people across the country are paying attention to what happens next.
Keep following the science, EPA» Let the EPA Administrator you support the agency’s review of new evidence on atrazine, and urge EPA to act swiftly once the science is in. We know atrazine is in our lakes, streams and drinking water. And we know exposure to the widely used herbicide has been linked to birth defects, infertility and hormone disruption. At next week’s meeting, scientists will focus in on exactly how atrazine affects children’s health, how best to monitor the chemical in our water supplies, and what scientists know about links to cancer.

One in Six Children has a Developmental Disorder. Parents, doctors, and scientists alike struggle to understand the causes and deal with the consequences. Scientists believe that industrial chemicals play a role in this “silent pandemic” (Grandjean and Landrigan 2006). However the chemical industry under current law is under no obligation to study the impacts or to produce products that are proven not to damage a child’s brain. (more…)

Endocrine-Disrupting Chemicals Exposure Elimination Act of 2011 introduced by Senator John Kerry, facilitates cooperation between regulatory agencies to reduce exposure to chemicals identified as endocrine disruptors. This Act is essential to facilitate and strengthen the new Safe Chemicals Act of 2011. The Act addresses one of the most serious threats to the security and economy of our country: the health and well-being of our children who today face mounting odds of being born with an endocrine-related disorder. Please contact your Senators and Members of the House of Representatives and ask them to cosponsor The Endocrine-Disrupting Chemicals Exposure Elimination Act of 2011.
Most people are not aware of the thousands of pesticides and their formulations that are in use today, some of them in huge volumes and on huge acreages worldwide. They comprise acaricides, algicides, antifoulants, avicides, bactericides, herbicides, insecticides, fungicides, molluscicides, nematicides, piscicides, rodenticides, virucides, and the related plant and insect growth regulators; chemosterilants; bird, mammal and insect repellents, insect pheromones and other attractants. Product formulations may contain more than one active ingredient, as well as synergists, “safeners”, and other ingredients formerly known as “inerts”.
One particular concern about pesticides is that they have been designed to disrupt biological systems, causing death to target organisms, such as insects or plants. Some actually work by acting on the endocrine systems of insects. The problem is that the biochemistry of most living things is similar enough that humans, wildlife and plants can also be adversely affected by pesticides. In the past, much of the human and wildlife health-related research on pesticides has dealt with more or less immediate toxicity at relatively high doses, or has been concerned only with the primary mode of action of a single active ingredient in the pesticide product. In recent years, these concerns have broadened to include other possible actions of the ingredients, and testing at exposure levels more relevant to what may be in the environment. Follows is the literature that explores the adverse effects of pesticides, as well as the adverse health effects of their metabolites and formulations. Effects may happen at extremely low doses; they may affect multiple signaling systems that control function and development; they may be subtle, long-term and/or delayed; and through parental exposure they may even affect subsequent generations.
