Cancer is one of the most dreaded diseases out there.
It's almost all of the times incurable. Even though there are advanced treatment options in place these days but, they are way too costly. Also, the survival chances are minimal. Still there are examples of people who are living a happy life after getting treated successfully. But, more work and research need to be done to help the increasing number of cancer patients.
Scientists are still in doubt regarding the causes of this dangerous disease. Is it because of the genes or the unhealthy lifestyle? Read on to find out.
Dr. Emma Smith, Cancer Research Institute, UK, said, "Healthy habits like not smoking, keeping a healthy weight, eating a healthy diet and cutting back on alcohol are not a guarantee against cancer, they do dramatically reduce the risk of developing the disease."
Also, people who move to countries with higher cancer incidence from countries of lower cancer incidence are seen to develop the same rate of tumour incidences. Earlier this year, the study by Johns Hopkins University, failed to include cancers like cervix, prostate, stomach and breast that can be linked to environmental causes.
So, it otherwise termed cancer as a 'bad luck'. So, here unhealthy lifestyle has no role to play in the disease's occurrence.
This because the incidence is quite high. According to Cancer Research UK's data, 339,000 new cancer cases were recorded in 2012 with 162,000 deaths. The cancer treatment in England is improving but, is still behind other European countries.
Dr. Yusuf Hannun, Stony Brook University, US, said, "While luck plays a role, factors in the world around us are much more important."
But, what about the rest? It still needs to be researched upon.
Professor Kevin McConway, Open University, said, "There would still be cancers, because of the way that cells divide in the body. But, there would be fewer of them if we can identify the underlying external triggers of cancer as well."
