Cancer is one of the most complex diseases doctors treat today. No two cancers are exactly alike — even if two people have the same type of cancer, the way their bodies respond can be very different. That’s where genetic testing comes in. It’s changing how doctors understand, diagnose, and treat cancer.
At Continental Hospitals, we believe in combining advanced medical technology with compassionate care. In this blog, let’s explore how genetic testing works, why it matters in cancer treatment, and how it’s helping patients receive more personalized and effective care.
What is Genetic Testing?
Genetic testing is a medical test that looks for changes, also called mutations, in your DNA — the material that carries information about how your body works. Some genetic mutations are passed down from parents, while others happen during a person’s life.
In cancer care, genetic testing can be done in two main ways:
Germline Testing: Checks for inherited mutations present in every cell of the body. This helps identify if you have a higher risk of developing certain cancers.
Somatic Testing (Tumor Testing): Looks for mutations that occur in cancer cells themselves. This helps guide treatment decisions and predict how a tumor might behave.
How Does Genetic Testing Help in Cancer Treatment?
Genetic testing is like a roadmap. It shows doctors the specific mutations causing the cancer and helps them choose the most effective treatments. Here’s how it makes a difference:
1. Personalized Treatment Plans
Not all cancers respond to the same treatments. By understanding the genetic changes in your cancer, doctors can recommend medicines or therapies that directly target those mutations. This is known as targeted therapy.
Example:
If a patient with breast cancer tests positive for a HER2 gene mutation, specific medicines like trastuzumab are more likely to work.
2. Predicting How Aggressive a Cancer Is
Some gene mutations can indicate whether a cancer is likely to grow quickly or spread. This helps doctors decide how intensive the treatment should be — whether a patient needs surgery, chemotherapy, radiation, or a combination.
3. Avoiding Unnecessary Treatments
If genetic testing shows that certain treatments won’t work for a patient’s specific cancer, doctors can avoid those options. This saves time, reduces side effects, and lowers healthcare costs.
4. Identifying Clinical Trial Opportunities
Many new cancer treatments are being tested in clinical trials. Genetic testing can help match patients to these trials based on their cancer’s mutations, giving them access to the latest therapies.
5. Checking Cancer Risk in Family Members
If a patient has a hereditary mutation like BRCA1 or BRCA2 (linked to breast and ovarian cancer), their family members can also get tested to understand their cancer risk. Early screening and preventive care can then be planned.
When Should You Consider Genetic Testing?
- Your doctor may suggest genetic testing if:
- You have a personal or family history of cancer, especially at a young age.
- You have a rare type of cancer or multiple cancers.
- Your cancer has returned or isn’t responding to standard treatments.
- You’re interested in targeted therapy or clinical trials.
At Continental Hospitals, our cancer specialists carefully evaluate each patient’s case before recommending genetic testing.
Is Genetic Testing Safe and Accurate?
Yes, genetic testing is generally safe. It usually involves a simple blood sample, saliva sample, or a small piece of tumor tissue. The results are highly accurate and help doctors plan better treatments.
It’s important to note that while genetic testing provides valuable information, it doesn’t always predict whether you will develop cancer. It only shows if you have a higher risk or if your cancer has specific mutations.
