The gene forms the blue print in the life of each and very organism. Every organism has two copies of a gene, which is obtained from each on his/her parents. Hereditary cancer occurs when a person is born with one copy of the damage-controlling gene damaged. These genes are usually tumour suppressor or oncogene. An individual who contained such a mutated gene is found to have 50% changes for development of cancer. The chances to pass the gene to next generation are also high. It has to be noted that all the individuals carrying this mutated gene does not develop cancer. The susceptibility for the incidence of the cancer is found to be more. The mutated gene is transferred in an autosomal dominant inheritance pattern.
