"Why The Dog Scan Will Not Replace The CAT Scan"

[F, Calla & Luca]

This is a serious topic, a copy of a post from a medical forum. I though it was very interesting. Some of this is truly amazing like detecting gas leaks with your phone.

"It is well known that dogs can detect cancer by sniffing a patient's breath.

Apparently some animals even like the smell of humans dying.

There are many diseases the nose knows, but humans cannot compete with dogs in their ability to discriminate odors.

 Cancer cells produce different metabolic waste products than normal cells, and dogs, which have a sense of smell 10,000 to 100,000 times greater than humans, can detect them by smell. Their sense of smell is so keen that they can detect parts per trillion. The results of the study showed that the dogs could detect breast cancer and lung cancer between 88 and 97 percent of the time.

An artificial nose can identify brands of coffee.

Now we can finally do better than dogs and detect lung, breast, colorectal, and prostate cancers from exhaled breath using a single array of nanosensors.

Apparently the dog scan will not replace the CAT scan.  To diagnose cancer we may someday use an electronic nose.  Perhaps the day will come when we will be able to breath into our I-phones, and an application will tell us whether we have cancer.

Andrea, I am so sorry for your loss. Your story touched my heart. Riley is amazing.

[Doris, Knox & Flash]

Can't imagine losing a sister.  So sorry...

[Linda, Webber and Seda]

That is such a sad, yet wonderful, story.  I can picture Riley at her side, taking care of her.  I am so sorry you lost your sister and Riley surely is an amazing dog.

[F, Calla & Luca]

A very sad story about your sister. Amazing though that Riley could detect something like that.

Thanks everyone for adding your own experiences to this.

[Sherri, Sophie, Winston, & Kitty]

You know it makes me wonder. Winston is always sticking his nose close to my chest. I sometimes think he just needs attention, either that or there is a perverted man trapped inside his furry body. But sometimes I think maybe I should get a check up. Maybe I'm just being paranoid but I can't help but wonder. It freaks me out a bit.

Dogs are so fascinating!

[Becka]

LOL Sherri--I'm cracking up at the idea of Winston as a furry little pervert.

[Nancy, Ned, Clancy, and Charlie]

I am amazed at what our dogs - well some of them - can detect. Thank you for sharing your experiences, Andrea and Jennifer.

Is anybody having trouble with the links. If so let me know. The post is from a site (Sermo) you need to sign in to but most of the links should be OK. Of course they all come up on my computer : )
