A new research has found that living in the city can lead to several types of cancers. 

The reason is that the amount of pollution is much higher in the cities than in the smaller towns.

Toxic chemicals called the Carcinogens have been implicated as the cause of these cancers. These toxins can be present in the food we eat or even the water we drink. As these carcinogens keep on accumulating in our body cancer might develop.

Moreover cancers are less likely to be detected early in the cities than in the suburbs.

A recent study on the residents of Illinois found that those residing in the city were more likely to have doctors diagnose common cancers like lung, breast, colorectal, or prostate cancer later in the disease's progression than their counterparts living in the rural areas.

In this study the rates for these late-stage cancers were highest in Chicago, the most densely populated and urban of the areas in the analysis, and tapered off the more rural and sparse an area's population became, according to the findings, which were based on a review of the 1998 to 2002 Illinois State Cancer Registry.

Hence regular screening is advisable for people past 30 years to detect cancers in the earliest stages.
