Understanding Your DNA and Cancer
Genomics FAQ 1: What is genomics and why is its importance to cancer research?
What Is Genomics?
Genomics is the study of your DNA, the instructions that tell your body how to function. Sometimes, changes in these instructions can lead to diseases like cancer. By studying these changes, doctors can better understand how cancer develops and how to treat it.
Why Is Genomics Important in Cancer Care?
Everyone’s cancer is unique. By examining the genetic makeup of your cancer cells, doctors can:
- Identify specific mutations causing the cancer.
- Choose treatments that target those mutations.
- Predict how the cancer might behave or respond to treatment.
This approach is known as “personalised medicine” because it tailors treatment to your individual genetic profile.
How Does Genomic Testing Work?
If your doctor recommends genomic testing, here’s what typically happens:
- Sample Collection: A small sample of your blood or tumour tissue is taken.
- DNA Analysis: Specialists examine the DNA in the sample to look for mutations.
- Results Discussion: Your healthcare team discusses the findings with you and how they might influence your treatment plan.
Benefits of Genomic Testing
- Targeted Treatments: Receive therapies designed to work with your specific cancer type.
- Fewer Side Effects: Potentially experience fewer side effects compared to traditional treatments.
- Better Outcomes: Increase the chances of successful treatment.
Questions to Ask Your Doctor
- Is genomic testing appropriate for my type of cancer?
- What will the test results tell us?
- How might the results change my treatment plan?
Understanding genomics can empower you to make informed decisions about your cancer care. Always feel free to ask your healthcare team any questions you have, they’re there to support you every step of the way.
