Breast cancer is a major health concern for women around the world. While there are many types of breast cancer, one of the most concerning and difficult-to-treat kinds is known as triple-negative breast cancer (TNBC). TNBC often requires more aggressive treatments than other forms of breast cancer and can be especially difficult to diagnose. In this article, we’ll look at what TNBC is, its symptoms, and the treatment options available for those diagnosed with it.
What is triple-negative breast cancer?
Triple-negative breast cancer (TNBC) is a subtype of breast cancer that does not express the hormone receptors for estrogen or progesterone and does not overproduce the HER2 protein. TNBC accounts for about 15 to 20 percent of all breast cancers. While this type of breast cancer is more aggressive and has a higher rate of recurrence than other types of breast cancer, there are still many effective treatment options available.
The most common treatment for TNBC is chemotherapy, which can be used to shrink the tumor and kill any remaining cancer cells. Other treatment options include targeted therapy, radiation therapy, and surgery. Some women with TNBC may also receive hormone therapy or immunotherapy.
It is important to talk to your doctor about all of your treatment options and make a decision that is right for you. With advances in treatments, many women with TNBC are able to live long and healthy lives after their diagnosis.
Who is at risk for developing triple-negative breast cancer?
There are several risk factors for developing triple-negative breast cancer, including:
- Personal history of breast cancer
- Family history of breast cancer (especially in a first-degree relative)
- Previous radiation therapy to the chest area
- Inherited genetic mutations, such as BRCA1 or BRCA2 mutations
- African-American or Hispanic ethnicity
- Being premenopausal or perimenopausal
If you have any of these risk factors, it’s important to talk to your doctor about your risks and what you can do to reduce them.
How is triple-negative breast cancer diagnosed?
There are a few different ways that triple-negative breast cancer can be diagnosed. A common way is through a mammogram, which is an X-ray of the breast. Other ways include a breast MRI, a breast ultrasound, or a biopsy.
A biopsy is when a small sample of tissue is taken from the breast and looked at under a microscope. This is the only way to definitively diagnose triple-negative breast cancer. There are two types of biopsies: needle biopsies and surgical biopsies. In a needle biopsy, a thin needle is inserted into the breast to remove cells or fluid. In a surgical biopsy, part of the tumor is removed surgically.
Triple-negative breast cancer can also be staging using imaging tests such as CT scans, PET scans, and bone scans. These tests help determine if the cancer has spread beyond the breast and to what extent.
Are there any clinical trials currently testing new treatments for triple-negative breast cancer?
There are a number of clinical trials currently underway testing new treatments for triple-negative breast cancer. These include trials testing new targeted therapies, immunotherapies, and combination therapies. Some of these trials are specifically for women with triple-negative breast cancer who have previously been treated with chemotherapy, while others are open to all women with this type of breast cancer. Clinical trials offer patients the opportunity to receive cutting-edge treatment that is not yet available to the public. If you are interested in enrolling in a clinical trial, speak to your doctor about your options.
What can I do to reduce my risk of developing triple-negative breast cancer?
There are a few things you can do to reduce your risk of developing triple-negative breast cancer:
- Maintain a healthy weight and body mass index.
- Get regular exercise.
- Limit your alcohol intake.
- Avoid smoking.
- Limit your exposure to environmental pollutants and toxins.
- Eat a healthy diet rich in fruits, vegetables, and whole grains.
- Consider taking a daily multivitamin or supplementing with folic acid, vitamin D, and calcium.
- Get regular screenings and mammograms, especially if you have a family history of breast cancer or are over the age of 40.
