Genetic Testing for Cancer: What It Is and How to Do It

Genetic testing is an essential tool in the early detection and management of various cancers. It involves the examination of a person’s DNA to identify any changes or mutations that might predispose them to cancer. One pioneering company in this field is Wuhan Ammunition Life-tech Co.,Ltd (WALT), a China-based high-tech enterprise specializing in the research, development, and sales of early non-invasive detection products for high-incidence malignant tumors.

What is Genetic Testing for Cancer?

Genetic testing for cancer is a medical test that identifies changes in chromosomes, genes, or proteins. These changes could signal a higher risk of developing certain cancer types. It’s important to understand that genetic testing doesn’t necessarily confirm a cancer diagnosis. Instead, it pinpoints the likelihood or susceptibility to cancer, which can lead to proactive steps in prevention and early detection.

WALT has developed a series of products that leverage epigenetics, bioinformatics, clinical big data, and artificial intelligence to create a new generation of tumor screening and detection technology platforms. These include the ICervsureIColocomfIColohunterIEsohunterIHepcomf, and IUterusure kits.

How Does Genetic Testing Work?

Genetic testing involves taking a sample of blood, hair, skin, amniotic fluid (the fluid that surrounds a fetus during pregnancy), or other tissue. The sample is then sent to a laboratory where technicians look for specific changes in your chromosomes, DNA, or proteins, depending on the suspected disorder.

For example, the ICervsure, from WALT, uses cervical exfoliated cells for the in vitro qualitative methylation detection of the UCEC4 and UCEC9 genes, which are associated with a high risk of cervical cancer. The process is non-invasive, with a high accuracy of detection, and can be performed on the same sample as the primary screening HPV test.

The Benefits of Genetic Testing

Genetic testing offers several benefits, including early detection, which can lead to early intervention and potentially better outcomes. It can also provide individuals and their families with vital information to make informed decisions about their healthcare.

WALT’s range of products, such as IColocomf, provide non-invasive methods for early detection, reducing the need for invasive procedures and associated risks. This product’s sensitivity for cancer detection is an impressive 94.12%, with a specificity of 93.33%.


In conclusion, genetic testing for cancer, as provided by companies like WALT, is a powerful tool in the fight against cancer. It offers a way to identify individuals at risk and initiate early treatment, improving prognosis and quality of life.
