This situation is caused by a person’ s genetic predisposition to cancer. In simple terms, genetic predisposition implies to the extent to which an individual’ s genetic makeup increases his or her risks of contracting cancer. This genetic predisposition issue has led to the emergence of the concept of cancer families, which have considerably higher cases of cancer compared to other families in a population. Families may be predisposed to a certain type of cancer or different types of cancer, mainly caused by a mutation in their gene (7 & 5).

Chance also plays a key role in predisposing some people to cancer than others. For example, many of the gene mutations that predispose people to cancer happen by chance (1 & 2). Whenever cells divide, they have to copy their genetic code completely, a process that is sometimes shrouded by mistakes. While in some cases the mistakes are fatal and end in the death of the daughter cells, some cases have the damages repaired (1 & 2). In addition, some mutations result in little or no difference in the viability and functionality of the cell.

An individual’ s immune system also plays a significant role in predisposing them to cancer. Age also plays a key role. For instance, healthcare practitioners say that if all men lived long enough they would get prostate cancer (1 & 2). Reasons thus abound, which attempt to explain the reasons every year, millions of people are diagnosed with cancer while the remaining billions do not suffer from the condition. In fact, in every three people, two never get cancer. What is more, most of the heavy smokers do not get cancer.

A study conducted by George Klein, Professor Emeritus at the Microbiology and Tumor Biology Center at the Karolinska Institute in Stockholm, Sweden, attempted to highlight this often overlooked fact. In the end, the researcher suggests that more studies ought to aim at unearthing the reasons rather many people are able to resist the dreaded disease.
