Why Has Cancer Become More Common in the Last Few Decades?

by Kavin Kajendran 

Cancer rates have been increasing over the past few decades, and while there isn't a single definitive answer, several factors contribute to the rising incidence of cancer:

Firstly, the biggest risk factor is that there are more older people than there were 20 years ago. The life expectancy is around 81 years old and studies have proven the longer you live the more time for the cancer to kick start. As we age, there is more time for damage in our cells to build up, and so more chance that some of this damage might eventually lead to cancer. 

Secondly, lifestyle choices have an effect on cancer. Unhealthy lifestyle habits such as smoking, poor diet, lack of physical activity and excessive alcohol consumption are strongly linked to an increased risk of certain cancers. Changes in lifestyle patterns, particularly in developing countries, have led to higher rates of cancer. 

Finally, environmental factors can lead to cancer. Exposure to environmental toxins and pollutants, such as chemicals in air and water pollution, radiation and certain chemicals used in food production and packaging, may contribute to the development of cancer. 

So, cancer is an inevitable disease and anyone can get cancer, whether you're extremely healthy and active or very unhealthy; it can develop in different ways. That is why you should try to prevent developing certain cancers with vaccines and just a simple balanced diet.
