Dinosaurs had cancer too, say scientists who discover first known case in the creatures

OTTAWA (AGENCE FRANCE-PRESSE) - Dinosaurs loom in the imagination as forces of nature, but a new study that identifies the first known case of cancer in the creatures shows they suffered from the debilitating disease, too.. Read more at

A badly malformed Centrosaurus leg bone unearthed in the Alberta, Canada badlands in 1989 had originally been thought by paleontologists to be a healed fracture.But a fresh examination of the growth under a microscope and using a technique also employed in human cancer care determined it was actually a malignant tumour.

"The cancer discovery makes dinosaurs more real," study co-author Mark Crowther told AFP."We often think of them as mythical creatures, robust and stomping around, but (the diagnosis shows) they suffered from diseases just like people."

The findings were published in the August issue of The Lancet Oncology.Most cancers occur in soft tissues, which are not well-preserved in fossil records, noted Dr Crowther, a dinosaur enthusiast and chairman of McMaster University's medical faculty in Canada.

"Oddly enough, under a microscope it looked a lot like human osteosarcoma," he said."It's fascinating that this cancer existed tens of millions of years ago and still exists today."Osteosarcoma is an aggressive bone cancer that still afflicts about three out of one million people each year.

In this horned herbivore that lived 76 million to 77 million years ago, it had metastasised and likely hobbled the giant lizard, the researchers said in the study.But neither the late-stage cancer nor a predator looking to make a meal out of slow and weak prey is believed to have killed it.

Because its bones were discovered with more than 100 others from the same herd, the researchers said, it was more likely they all died in a sudden disaster such as a flood, and that prior to this catastrophe, the herd protected the lame dinosaur, extending its life.

Lead researchers Dr Crowther and Dr David Evans, curator of vertebrate paleontology at the Royal Ontario Museum in Toronto, and their team sifted through hundreds of samples of abnormal bones at the Royal Tyrrell Museum in Drumheller, Alberta, to find the bone with a tumour, which is about the size of an apple.

The team also used high-resolution computed tomography (CT) scans, a multidisciplinary diagnostic technique used in human cancer care.Dr Crowther said dinosaurs would probably have been at higher risk of osteosarcoma, which affects youths with fast-growing bones, because they grew very quickly and big.

"In terms of the biology of cancer, you often hear about environmental, dietary and other causes of cancer. Finding a case from more than 75 million years ago, you realise it's just a part of life," said Dr Crowther. Read more: The Straits Times »

Sexual offences, quotas and serving NS: K Shanmugam speaks frankly about women’s issues

He also gives his take on whether quotas would work and responds to comments about women serving National Service.

'Gnarly' tumor shows dinosaurs got cancer, tooWhen scientists first unearthed fossils of a horned dinosaur called Centrosaurus in the badlands of Dinosaur Provincial Park in Canada's Alberta province in 1989, they spotted a badly malformed leg bone they figured was a healed fracture. The malformation was a manifestation of osteosarcoma, an
