The Medicine University John Hopkins has done a study to demonstrate that most of our cancers are not developed because of external factors, they are developed due to bad luck in the mutations of mother cells. These mutations occur when mother cells multiply themselves, smoking and other external factors can also contribute to cancer formation, but these are not the main factors in the development of cancer. Scientifics have categorized cancer into 31 different groups, divided into two main categories. 7 of those are caused by smoking and having Hepatitis C, the resting 22 are caused by the “bad luck” factor.
