Cancer Genetic Testing Q&A

What is cancer genetic testing?

Cancer genetic testing is a way of assessing your risk of developing some forms of cancer. The test detects any mutated genes, which could, in time, become cancerous. Glendale Obstetrics and Gynecology, PC partners with Myriad Genetics to provide cancer genetic testing.

Cancer genetic testing detects inherited genes that haven’t yet become cancerous, enabling you to take positive action to prevent cancer in the future. 

In addition to the genes you inherit that have mutations, seemingly healthy ones can also change throughout your life. Acquired gene mutations cause more cases of cancer than inherited ones.

Another type of cancer genetic testing, tumor DNA sequencing, can help your doctor select the most effective treatments if you receive a cancer diagnosis.

What conditions can cancer genetic testing identify?

The most common examples of cancers genetic testing can identify are:

BRCA mutations

Inherited mutations affecting your BRCA1 or BRCA2 genes significantly increase your risk of breast and ovarian cancers, fallopian tube cancer, and cancers of the pancreas and peritoneum.  

Lynch syndrome

Lynch syndrome is an inherited condition that increases your risk of endometrial and ovarian cancers and cancers of the colon, stomach, pancreas, small intestine, kidney, and brain.

Should I consider cancer genetic testing?

You might benefit from cancer genetic testing if you meet any of the following criteria:

  • Several close relatives have cancer
  • Many relatives on one side of your family have the same cancer
  • Family members have multiple cancers linked to one genetic mutation
  • A family member has a rare form of cancer
  • Your ethnicity increases your risk of certain cancers
  • Other family members cancer genetic testing confirmed a mutation
  • Family members developed cancer at a younger than normal age
  • A family member has more than one form of cancer

The Glendale Obstetrics and Gynecology, PC team discusses these risk factors with you to help you decide whether cancer genetic testing is right for you. They use the National Comprehensive Cancer Network (NCCN) guidelines to help you decide.

What does cancer genetic testing involve?

Cancer genetic testing requires a sample of your DNA, which you can provide with a mouth swab. The lab analyzes the cells to identify any genetic mutations. If you have any, your OB/GYN can discuss your options, such as preventive treatment.
