Ancient Dog Cancer Might Help Scientists Treat Human Cancer

CTVT is the abbreviation for canine transmissible venereal tumor, a type of tumor of the external genitalia of dogs and other species of canines. This infection is being passed from animal to animal while mating and is one of the three known cancers in mammals. After much investigation, it was discovered that this type of cancer diverged from canids over 6,000 years ago, but it possible originated 11,000 years ago. Scientists found out that the before-mentioned ancient dog cancer might help them treat human cancer.

In recent times, scientists became more and more interested in this type of cancer. This is why a team of scientists at the University of Cambridge, led by Elizabeth Murchison, have been investigating CTVT. The team has received samples of cancer from all over the world to help them in their investigation better.

With their extensive assortment of samples, the team succeeded in designing the first genetic map of the canine transmissible venereal tumor.

Ancient Dog Cancer Might Help Scientists Treat Human Cancer

The scientists were able to observe how this type of cancer evolved over time and discover an incipient pattern of how cancer will develop in humans in the future, and maybe a way to improve its impact. They also found that even after so many thousands of years, the cancer cells in canine species did not curiously become more and more aggressive.

Quite contrary, they are more comfortable now to cure than would have been before. A dog that has CTVT needs only one dose of chemotherapy to be healed. The truth is that the tumor does not affect dogs that much, and it does not develop further because of the small damage it does is enough.

Scientists have come with a new plan of action to cure cancer, and it does not involve killing it, but to keep it stable. They are sure that, over time, cancer in humans will behave the same way the ancient dog cancer did – it will exist and will do little harm, but that’s all. Humans would be able to live with it and cure it rapidly.
