Hereditary cancers are detected through genetic testing. This is an analysis of an object's genes, chromosomes, or proteins. Genetic testing helps:
Predict disease risk Identify carriers. This is someone who does not have the disease but has the disease gene Diagnose the disease Find out the high-risk history of a certain disease Genetic testing is done by taking a sample of blood or tissue that contains genetic material such as the inner cells of a certain object. More than 900 genetic tests are available for a variety of diseases including breast, ovarian, colon, thyroid, and other cancers.

Discovering a mutated gene that can offer a chance to reduce the likelihood of cancer through genetic screening or other measures such as following a healthy lifestyle, paying attention to nutrition, foods that can inhibit cancer cancer cells.
Currently, Vinmec International General Hospital is the first medical facility in Vietnam capable of implementing cancer screening by combining 4 technologies: genetic testing, endoscopy, ultrasound and laboratory testing. immunity. In particular, cancer screening with genetic technology is a method that is considered a breakthrough in medicine.
Early screening is considered the "golden key" to detect and provide prevention methods, reduce the risk of death and costs for patients. Due to late detection (70% of patients are treated when they are at the end stage), the death rate from cancer in Vietnam is very high.
To learn more about screening methods and reduce the risk of developing hereditary cancer, you can contact Vinmec Health System nationwide, or register online HERE.
