The increased incidence of cancer can also be attributed to changes in the environment mostly from industries located too close to residential areas. The improper disposal of waste products pollutes our air, water and agricultural products that's consumed by us on a daily basis leading to causation of cancer in the population. So it would be wise for those living close to these industrial complexes to relocate to avoid being exposed to this pollutants. Thanks for the great read @prameshtyaghi.
