In the past, cancer treatment and detection were classified according to the location of the tumour in the body, ignoring the relationship between gene mutation and cancer. Current studies have found that genetic mutations can cause many types of cancer and cause growth in tumours at different parts of the body. Therefore, once these genetic mutations are found, targeted and effective treatments can be adopted during the early stage.
There are more than 4,000 new breast cancer patients diagnosed in Hong Kong each year, and about 10% of the cases are related to gene mutations, and BRCA 1 and BRCA 2 are the main high-risk mutated genes*. Although carrying a BRCA mutated gene does not mean that you have breast cancer, but the risk of breast cancer will be several times higher than the people without the gene mutation. BRCA genetic testing can detect whether the body carries this genetic mutation, and prevent it as soon as possible to reduce unnecessary burden.

The Importance of Understanding Breast Cancer Risks?
To know if you are a person with a high risk of breast cancer, breast cancer genetic testing is a popular cancer detection method. Breast cancer genetic testing mainly detects two breast cancer genes, BRCA1 and BRCA2. If genetic mutations are detected, both men and women have a high risk of breast cancer and other related cancers. (For more information about BRCA gene mutations, please refer to: Is Breast Cancer Hereditary? Know more about BRCA Gene Mutation.)
Studies have shown that early detection of genetic mutations can reduce the risk of breast cancer by 90%. With targeted prevention strategies, patients can reduce the risk of advanced cancer. Early detection and early treatment can reduce the patient's physical, mental, and economic burden. At the same time, early treatment can prevent cancer cells from spreading to other body parts, thereby reducing the difficulty of the treatment process, and increasing the survival rate of the patients.
Codex Genetic BRCA 1&2 genetic testing
Codex Genetics provides CoGENESIS®BRCA screening which detects BRCA1 and BRCA2 gene mutation by genotyping. There are more currently more than 5,000 BRCA1 and BRCA2 gene mutations known to increase cancer risk. CoGENESIS®BRCA screening covers 3,049 of the most important mutations.
