Scientists discover new link between marijuana smoking & testicular cancer risk
https://www.sciencealert.com/men-who-smo...lar-cancer

EXCERPT: . . . A study published Wednesday in JAMA Network Open found that men who smoked one marijuana cigarette, or joint, daily for 10 years or more had an estimated 36 percent increased risk of developing testicular cancer compared with men who had never smoked the substance. To come to their conclusion, researchers analysed 25 studies that looked at the link between marijuana use and testicular cancer, lung cancer, oral cancer, and head and neck cancer. Though the researchers found no association between regular marijuana use and lung, neck, or oral cancer, they did find that regular weed smoking over many years could heighten a man's risk of testicular cancer.

Like smoking cigarettes, smoking marijuana releases carcinogens, or substances that can increase a person's risk of developing cancer. That's because cannabis, the plant marijuana is derived from, is like any other plant in that it burns and releases smoke when you light it, according to Dr. Jeffrey Chen, the director of the UCLA Cannabis Research Initiative. ... The study's researchers were unable to determine why their meta-analysis showed a link between smoking pot and testicular cancer but none of the other three cancers they analysed. [...] And, of course, the study can't prove a cause-and-effect relationship. Nonetheless, the researchers said their study offers insights into how long-term marijuana smoking could affect men and raises red flags about new, understudied consumption methods like vaping...

Study contends humans exposed to 44 TIMES more BPA toxin than previously thought

INTRO: Humans are exposed to far more hormone-disrupting chemicals than previously thought, according to a new study. Patricia Hunt, the researcher at Washington State University who first discovered that BPA, a dangerous toxin in plastics, can cause cancer and other diseases and disorders, has now developed a more accurate method of measuring it.

In a study published today, Dr Hunt reveals the new tool shows the 'safe' limit of BPA stipulated by the US Food and Drug Administration is flawed. In fact, it is 44 times higher than what Dr Hunt considers safe. 'This study raises serious concerns about whether we've been careful enough about the safety of this chemical,' Dr Hunt, a corresponding author on the paper, said. 'What it comes down to is that the conclusions federal agencies have come to about how to regulate BPA may have been based on inaccurate measurements.' (MORE - details)
