When it comes to breast cancer, chemotherapy is usually one of the treatment options that’s considered to be fairly effective. However, this is not the case with a particular form of the disease known as triple-negative breast cancer. While doctors will still use chemotherapy as the primary form of treatment, there is a higher chance of it being ineffective than with other forms of breast cancer. The good news is that it’s not the end of the road if chemotherapy doesn’t work for you.
Generally, breast cancer can be defined by the receptors it has to one or more of three possible hormones in the body. These are estrogen, progesterone, and human epidermal growth factor (HER2).
The presence of these receptors makes it easier for your doctor to determine which type of hormonal treatment to start with to destroy the cancer cells. Hormonal therapy is usually the first course of action as it’s the gentlest of the options and can be effective in the earliest stages.
With triple-negative breast cancer, however, there are no receptors for any of those three hormones and so hormonal therapy will not be effective.

Apart from not being receptive to hormonal therapy, triple-negative breast cancer tends to be a more aggressive form of cancer. That means it has been known to progress quickly and spread from the breast tissue to other organs.
To deal with this, doctors often have to use aggressive treatment methods such as chemotherapy, radiation, immunotherapy, and surgery. Of these methods, chemotherapy is used most often as it’s effective regardless of the stage of the disease.
If you’re going to need surgery, chemotherapy may also be used to reduce the size of the tumors to reduce the risk of complications during the procedure.
While chemotherapy is the go-to treatment for triple-negative breast cancer, it’s only effective in 50% of patients. In the other half, the cancer cells either don’t respond at all or respond partially, making it easier for the disease to
continue spreading. For some time, doctors and researchers were not sure why this was happening. Fortunately, recent studies have given some insight into what happens.
According to these studies, the cells in triple-negative breast cancer have the ability to modify a reversible molecular pathway that makes them resistant to chemotherapy. The result of this resistance is that the cells would survive the course of treatment and flourish once it was done.

Until recently, many people didn’t have any other options if chemotherapy wasn’t effective. This was concerning because of the high rate of failure with this form of breast cancer.
The new studies regarding how the cancer cells became resistant to treatment made a significant difference in the way forward after chemotherapy.
Doctors can now recommend a few targeted drug therapies that are designed to attack specific molecules in the cancer cells. These drugs are meant to disrupt how the cells operate and therefore kill them.
If you need surgery, this kind of therapy can also be helpful for reducing the size of your tumors. While only a few targeted medications are currently available, the number continues to grow as they are approved by the Food and Drug Administration (FDA). There are also clinical trials that can be great for those with late stages of the disease or for whom chemotherapy has already proven ineffective.
Triple-negative breast cancer is considered to be rare because it only affects about 15% of those who are diagnosed with breast cancer. However, up to 40% of that figure is likely to be Blacks.
If you’ve been diagnosed with this aggressive form of cancer, it’s best to talk to your doctor early about how they’ll handle it if chemotherapy fails. Having a plan means you can act quickly against the disease’s spread.
