Microchipping at the vets

They were SOOOOO worried. can'tcha tell??

 

OMG, they are adorable!!

 

I just read an article that said microchips can cause cancer.

 

I would like to know more about microchips causing cancer as I have my dog scheduled to be spayed beginning of April and was going to have her chipped at that time as she would be under. Now this has me wondering.

 

Microchipps cause cancer???
Where'd you read this?

 

Implanted Microchips Cause Cancer

The Institute of Experimental Pathology at Hannover Medical School in Germany reported , "An experiment using 4279 CBA/J mice of two generations was carried out to investigate the influence of parental preconceptual exposure to X-ray radiation or to chemical carcinogens. Microchips were implanted subcutaneously in the dorsolateral back for unique identification of each animal. The animals were kept for lifespan under standard laboratory conditions. In 36 mice a circumscribed neoplasm occurred in the area of the implanted microchip. Macroscopically, firm, pale white nodules up to 25 mm in diameter with the microchip in its center were found. Macroscopically, soft tissue tumors such as fibrosarcoma and malignant fibrous histiocytoma were detected."

Ecole Nationale Veterinaire of Unite d'Anatomie Pathologique in Nantes, France, reported, "Fifty-two subcutaneous tumors associated withmicrochip were collected from three carcinigenicity B6C3F1 micestudies. Two of these 52 tumors were adenocarcinoma of the mammary gland located on the dorsal region forming around the chip. All the other 50 were mesenchymal in ori! gin and were difficult to classify on morphological grounds with
haematoxylin- eosin."

Marta Vascellari of Instituto Zooprofilattico Sperimentale delle Venezie at Viale dell'Universita in Legnaro, Italy reported examining a 9-year-old male French Bulldog for a subcutaneous mass located at the site of a microchip implant. "The mass was confirmed as a high-grade infiltrative fibrosarcoma, with multifocal necrosis and peripheral lymphoid aggregates."

The Toxicology Department of Bayer Corporation in Stillwell, Kansas reported, "Tumors surrounding implanted microchip animal identification devices were noted in two separate chronic toxicity/oncogenicity studies using F344 rats. The tumors occurred at a low incidence rate (approximately 1%), but did result in the early sacrifice of most affected animals, due to tumor size and occasional metastases. No sex-related trends were noted.

All tumors occurred during the second year of the studies, were located in the subcutaneous dorsal thoracic area (the site of microchip implantation) and contained embedded microchip devices. All were mesenchymal in origin and consisted of the following types, listed on order of frequency: malignant schwannoma, fibrosarcoma, anaplastic sarcoma, and histiocytic sarcoma.

 

I think breatthing these days causes cancer.

With such a low rate.. i'd rather have my animals identified and have a 95% chance of returning home. than to not...

 

LOL Yup, breathing causes cancer along with everything else in this life!
I too would rather microchip.

 

i was reading the other day how eating chocolate was good for memory and your heart, but caused cancer. LOL Geeze....I for one am NOT giving up my chocolate!!! NO wayyy

 

I myself would rather tattoo than microchip in that case but it's still up to the "finder" of the dog if he/she will be scanned or returned regardless of chip, tattoo etc... I think it's a good idea and a great practice when it works but seriously...a valueable show dog found by someone or a dog like True's found by someone is likely to NOT be scanned or returned to the owner regardless...unfortunately it seems that's the way it works.

Sams, breathing and being in the world does cause cancer. We are surrounded by a multiple number of carcinogens 24/7 some stuff just makes it more likely to get it...for some people...depends on all kinds of stuff. Animals on the other hand...scar tissue of any kind seems to be likely and possible to cause cancer.

Sarah, Actually you have a valid point I never thought about!
Tatto! What a great idea!!!!!!!
My dog Daisy has tattoo's X2 on her belly and her ear. This proves the shelter she came from! Very very great idea. Probably cheaper too. You do have a point though, if the finder doesn't report it, what good is it?
None I imagine. But it is worth a try. You just don't know!
Working in Intensive Care Unit for the last 23 years, I can tell some horror stories about Cancer. IT SUCKS!!!!
But it is all around us.
I don't think of it because I would never go to work.
Now, on another note, I have been thinking about True all week!
I got a loan because my daughter just had a baby and I wanted to give her some money and buy some nursery items, etc etc..... anyway, I have extra money that I usually don't have and I can't help thinking (Even though I am into rescue) How wonderful a True pit puppy would be! I would love to be able to show the dog (even though I honestly don't know how but I would be willing to learn) and be so proud of the blood lines! She does know so much about lines unlike me (Sarah You are impressive too)
Anyway, I wish I could get a puppy but my inn is currently full) some day I will contact her though! Her dogs are impressive!

 

That is definately true about True's dogs, some REALLY impressive bloodlines in there and whatnot. Showing, especially when you show in the smaller shows and orgs. is really fun to do. I'm sure ADBA is similar to the international Dog shows where you show your own dog looking nice but no expert like on TV where most dogs are shown by professional handlers.

I showed my Boerboels for a bit too and it was a lot of fun and work (good work though) and since these dogs are all wash and go it makes it so much easier than something more foo foo and fuzzy...LOL

Depending on where you're located you can do stuff like Weight Pulling with them too and agility! I might do some Agility with Bella but I've had my eye on weight pulling with a small pit just like her so I can't help but try her out at that first. She's so easily trained though that Agility would really show that talent off too. I need to get involved in our dog club out here and see if they'll let me work Agility with them. FUN stuff and those pits are sooooo versitile.

My Husband is a tattoo artist and will likely tattoo our dogs once he gets a new power supply at work (the pedal they push to make the machine run) to bring one home. Quick and easy and is less invasive than an actual foriegn body like a Micro-chip. Black tattoo ink is just basically carbon which we're all made of and hasn't show (yet) to be a cause of cancer...LOL... Time though...it's the second oldest profession they say and so I would imagine t his is proof that black tattoo ink is non-cancer causing.

I was being sarcastic about breating giving you cancer.... LOL
