Brothers and Sisters Suffers From Cancer by Genetic Inheritance







Data Retrieved from Apple Daily 6th June 2018. 


Cancer is a common disease. There are many factors that trigger cells in becoming cancerous: aging, poor life style, poor diet, or pollution can all lead to cancer. Normally, people are born with the ability to repair and control damages caused by these factors. These natural abilities are coded in some specific genes known as the damage-controlling genes. Hereditary cancers occur when we born with one or more of these genes mutated. In other words, these cancer-causing gene mutations can be inherited.

Family history is important in determining the chance of inheritance. Everyone inherits two copies of the same gene from our parents, one from father and the other from mother. Most of the time, both inherited copies are normal. If one of the parents has a mutation in these genes, then it means that there is a 1 in 2 chance (50%) of inheriting the same mutation. Although, of all cancer cases, only about 10% are hereditary, it is still important to find out your hereditary risk so that early prevention can be made.
