Knowing your family health history is important especially when you have been diagnosed with a cancer
What is genetic cancer?
Genetic cancer means that a person was born with a hereditary mutation, or change, that makes this person more likely than usual to get that genetic cancer. This hereditary mutation could have come from either the paternal or maternal side both. Genetic cancer may also be called hereditary cancer or cancer in the family.
Around 8% to 24% of all cancers are due to genetics. This is a very small percentage of cancers, so how can you tell whether cancer is in genetics?
We have some rules to identify cancer:
Having several relatives with cancer on the same community of the family, especially if they were diagnosed at a younger age
Having a single member in the family with multiple tumors, especially in the same body part.
Hereditary testing for genetic cancer
Genetic cancer is found through hereditary testing. This is the test of a person’s genes, proteins, or chromosomes. Analysis can:
Help in predicting the risk that someone will get a genetic disease.
In detecting carriers of the disease. These are ones who do not have the disease but have a copy of the disease gene.
Diagnose a genetic disease.
Find out the likely course of a disease.
Hereditary testing is done by taking a sample of tissue or blood that contains genetic stuff, such as the cells inside a person’s cheek. More than 1000 hereditary tests are available for many different diseases, including the brain, ovarian, colon, thyroid, breast, and other cancers. Learn more about hereditary testing.
What your genetic research of cancer can show
Information from your family’s research can help a doctor to determine whether:
You or others in your family may benefit from hereditary counselling. This is functional counselling that explains the risks of transferred cancer and the causes, risks, and limitations of genetic testing.
You or others in your family may benefit from hereditary testing.
You need more demanding care than people with non-genetic cancer, even if you do not need hereditary testing.
This is how you can protect yourself by detecting genetic cancer in advance and you can prevent yourself by discussing your family health history with your health care doctor. This is especially true if you have been diagnosed with cancer. To know more about family lineage visit Geneology4u.
