There are now studies that claim broader genetic testing may improve breast cancer risk assessment. Not only that, but it may be effective for determining the risk of other cancers. Those interested in this process can learn more about this process can go to this website, and there is also some information about how it works below.

What Is Genetic Testing for Cancer?

Genetic testing for cancer, like the services offered by TruGenX, estimates a person’s chance of developing cancer at some point in their life. This is done by searching for certain changes in the person’s proteins, chromosomes, or genes. The official name for these changes is mutations.

There are several genetic test options available for some types of cancer. Some of the most common that can be genetically tested for include colon cancer, breast cancer, and ovarian cancer, according to There are other cancers that can be tested for, as well, including kidney cancer, sarcoma, melanoma, pancreatic cancer, prostate cancer, and thyroid cancer.

How Does Genetic Testing for Cancer Work?

With genetic testing for cancer, there are a few things to know. It can be used for predicting the risk someone has of acquiring a certain disease. It can also be used to find if the genes being passed to a person’s children will increase their risk of cancer. With the results of the genetic testing, the information can be given to provide guidance for a healthcare professional to ensure proper care.

There is not a genetic test that can determine if someone will develop cancer for sure, but testing can tell someone if they have a higher risk than other people. Only some people with a gene mutation will actually develop cancer. This means that a woman may have a 45% up to 65% chance of breast cancer, but she may not ever actually develop this disease. However, a woman with a 25% chance could develop cancer.

Hereditary Risk Factors for Cancer

Hereditary cancers are any cancers that are caused by a type of inherited gene mutation. Inherited genes are those that are passed from the parent to the child in a family. There are a few factors that suggest an increased risk for some types of hereditary cancer.

A family history of cancer is one sign. Having three or more relatives on the same side of the family that have the same type of cancer is a strong indication that future generations may also develop this cancer. Another sign is cancer that occurs at an early age. If two or more relatives are diagnosed with cancer while they are young, it can indicate future cancer issues. Multiple cancers are another sign. If a relative has two or more types of cancer, it may increase a future generation’s risk of cancer.

Why Consider Genetic Testing for Cancer?

While genetic testing for cancer is not foolproof or definite, there are times when it can be beneficial. If someone believes they may be at risk for cancer, genetic testing may be a smart way to know how high this risk is.
