Cancer research has just got a huge boost. The rejuvenated shot comes with the development of an error free and accurate test by scientists that predicts the chances of being implicated with cancer up to 13 years in the future.

The breakthrough was made by researchers at Harvard and Northwestern University, by making use of the discovery of tiny but significant changes taking place in the body, more than a decade before cancer was diagnosed.

According to the research, published in the online journal Ebiomedicine, the protective caps on the ends of chromosomes, which prevent DNA damage, were more worn down for those who went on to develop cancer.

The protective caps, better known as “telomeres”, were found to be much shorter than they should have been. They continued to get shorter and then suddenly stopped shrinking four years before the cancer developed.

Dr Lifang Hou, the lead study author, told The Telegraph, “Because we saw a strong relationship in the pattern across a wide variety of cancers, with the right testing these procedures could be used eventually to diagnose a wide variety of cancers.”

“Understanding this pattern of telomere growth may mean it can be a predictive biomarker for cancer. We found cancer has hijacked the telomere shortening in order to flourish in the body”, he further said.

Study Shows that Humans Are Influencing Cancer in Wild Animals

Besides indulging in cancer causing behaviour like smoking, poor diet and low hygiene, human beings are also changing the environment in such a way that it can lead to the deadly disease in many species of wild animals, researchers have warned.

Besides indulging in cancer-causing behaviour like smoking, poor diet and low hygiene, human beings are also changing the environment in such a way that it can lead to the deadly disease in many species of wild animals, researchers have warned.

“Cancer has been found in all species where scientists have looked for it and human activities are known to strongly influence cancer rate in humans,” said Mathieu Giraudeau, postdoctoral student at the Arizona State University in the US.

“So, this human impact on wild environments might strongly influence the prevalence of cancer in wild populations with additional consequences on ecosystem functioning,” he added.

The study, published in the journal Nature Ecology & Evolution, pointed out many pathways including chemical and physical pollution in our oceans and waterways, accidental release of radiation into the atmosphere from nuclear plants, and the accumulation of microplastics in both land- and water-based environments, that show where human activities are already taking a toll on animals.

In addition, exposure to pesticides and herbicides on farmlands, artificial light pollution, loss of genetic diversity and animals eating human food are also known to cause health problems.

“We know that some viruses can cause cancer in humans by changing the environment that they live in — in their case, human cells — to make it more suitable for themselves,” explained Tuul Sepp, postdoctoral student at the varsity.

“Basically, we are doing the same thing. We are changing the environment to be more suitable for ourselves, while these changes are having a negative impact on many species on many different levels, including the probability of developing cancer,” Sepp added.

Even something such as artificial light and light pollution, as well as food meant for humans, are negatively affecting wild animals

Ruling that “cancer in wild populations is a completely ignored topic”, the researchers have urgently called for studies on cancer and its causes in wild animal populations.

“We want to highlight the fact that our species can strongly influence the prevalence of cancer in many other species of our planet,” Giraudeau said. (IANS)
