Targeted biological therapies for breast cancer
We tailor biological therapies to work against specific types of breast cancer, which is why they are known as targeted. For example, we use some therapies on patients who have the HER2 gene in their breast cancer cells -- known as HER2-positive. We use different therapies in patients without that gene -- HER2 negative.
Genetic testing can identify particular types of breast cancer that respond well to targeted biological therapies.
There are three main types of biological therapies:
- Antibodies that use the own immune system to attack cancer cells. This is also known as immunotherapy.
- Lab-made compounds that are similar to antibodies and are injected as a drug.
- Molecular drugs that interrupt the signals cancer cells rely on to grow.
Biological therapy clinical trials for breast cancer
Our breast cancer patients at times have access to clinical trials that investigate new biological therapies or other treatments. Talk with your doctor about whether a clinical trial might be right for you.
