Doctors may have found secretive new organs in the center of your head By Katherine J. Wu The New York Times Oct 20, at AM After millenniums of careful slicing and dicing, it might seem as though scientists have figured out human anatomy.

Email Men who took soy supplements after having their prostate cancer removed prostate cancer institute just as likely to see their cancer return as men who didn't take soy, in a new study. According to the American Cancer Society, prostate cancer is the second most common cancer among men after skin cancer. It's estimated that one in every six men will be diagnosed with it. Some doctors believed compounds found in soy - known as isoflavones - might help prevent prostate cancer, but more recent studies have found those and other nutritional supplements don't reduce the risk of developing the disease see Reuters Health story of May 5, here:. For the new study, published in the Journal of the American Medical Association, Bosland and his colleagues randomly assigned men who'd had their cancerous prostates surgically removed less than four months earlier to drink either a soy or placebo beverage every day for up to two years between July and May

A few dozen organs, a couple hundred bones and connective tissue to tie it all together. But despite centuries of scrutiny, the body is still capable of surprising scientists.

Advertisement A team of researchers in the Netherlands has discovered what may be a set of previously unidentified organs: a pair of large salivary glands, lurking in the nook where the nasal cavity meets the throat. If the findings are confirmed, this hidden wellspring of spit could mark the first identification of its kind in about three centuries.

Subjects must meet all of the following criteria to be enrolled in this study: 1. Male aged 21 years or older. Ability to provide signed informed consent and willingness to comply with protocol requirements. Biopsy confirmed presence of adenocarcinoma of the prostate gland. At high-risk for metastatic disease by a stage of cT3, cT4, or a total nomogram score of greater than or equal to 5.

Any modern anatomy book will show just three major types of salivary glands: one set near the ears, another below the jaw and another under the tongue.

Matthijs Valstar, a surgeon and researcher at the Netherlands Cancer Institute and an author on the study, published last month in the journal Radiotherapy and Oncology.

It ferries the tasty chemicals in food to the microscopic cells that can sense them. It even comes imbued with crude healing powers, waging war against germs and speeding the closure of wounds.

Doctors take numerous precautions to avoid damaging the glands when administering radiation therapy, which can, with a single misdirected zap, permanently compromise the delicate tissues. While perusing a set of scans from a machine that could visualize tissues in high detail, the researchers noticed two unfamiliar structures dead center in the head: a duo of flat, spindly glands, a couple inches in length, draped discreetly over the tubes that connect the ears to the throat.

Puzzled by the images, they dissected tissue from two cadavers and found that the glands bore similarities to known salivary glands that sit below the tongue. The new glands were also hooked up to large draining ducts — a hint that they were funneling fluid from one place to another.

They are more petite and tougher to find through imaging or scanning than their heftier cousins. Fitzhugh and Mowery were slightly more persuaded, but both called for more data.

The original group examined by the researchers was made up entirely of people with prostate or urethral gland cancer, and included only one woman among subjects. The imaging techniques used in the study were also prostate cancer institute tailored to hunt for tumorous growths in this patient population. It may be worth widening these experiments to include a new group of people, using different prostate cancer institute, she said.
