What Do You Attribute To The Hesitancy Black Women Have To Partake In Clinical Trials
RF: The traumatic history of exploitation and racism in the scientific and medical industries has understandably posed huge barriers of trust for women of color. Nearly a third of Black women believe scientists cannot be trusted, compared to only 4% of white women. As a result, the average participation by Black women in breast cancer clinical trials overall is less than 3%. This is where a platform like Ciitizen dedicated to democratizing health data and empowering patients to take charge of their treatment journey is critical. By giving Black patients tools to safely store and access their medical data, Ciitizen fosters trust between Black patients and researchers.

Statistics Dont Account For Late Recurrences
When comparing triple-negative breast cancer to positive tumors, its important to keep in mind late recurrences. Most statistics are presented as five-year survival rate, and in this setting, triple-negative breast cancer can look more ominous. But looking at longer periods of time, say 20 years following diagnosis, this may be different.
What Is The Recurrence Rate Of Triple
A 2019 study found that roughly 40% of people with stage 1 to stage 3 TNBC will see their cancer return after standard treatment. The remaining 60% will have long-term survival without recurrence.
The outcomes of treatment vary. About 42% of those with this form of cancer will have a rapid relapse after standard treatment. This recurrence typically occurs within the first 23 years following the initial diagnosis.
It is not currently possible to predict who will experience a relapse in their cancer, even if they have had intensive chemotherapy.
Triple-negative breast cancer can recur in various areas of the body and at local, regional, and distant levels:
- Local means that the cancer remains in the breast and has not spread.
- Regional is when the cancer spreads from the breast to lymph nodes and other structures located nearby.
- Distant refers to cancer that has spread far from the breast to other organs, such as the liver or lungs.
A 2017 study examined the patterns of recurrence among 1,930 people with TNBC. The researchers divided the patients into two age groups: 15% were younger than 40 years at the time of their diagnosis, and 85% were 40 years or older.
The researchers found only a small difference between the two groups in terms of recurrence of the cancer on the local level: 6% of those under 40 versus 5% of those aged 40 or above.
The same study found that the rate of regional recurrence was 2% for both groups.

What Is Stage 3 Triple Negative Breast Cancer
Typically, triple-negative breast cancer patients will receive a combination of surgery, radiation therapy, and chemotherapy.
Research shows that survival rates are higher when chemotherapy is used to shrink the tumor before surgery. Doing chemotherapy before surgery usually means fewer cancer cells in the body at the time time of surgery. This makes it less likely for cancer cells to spread to other areas of the body during the surgery.
Another option to treat triple-negative breast cancer is using drugs that inhibit the poly ADP-ribose polymerase enzyme. Particularly in patients that also test positive for BRCA mutation, PARP inhibitors make it harder for the cancer cells to survive.
Finally, a combination of immunotherapy and chemotherapy may treat advanced triple-negative breast cancer that tested positive for the PD-L1 protein. Immunotherapy helps the patients immune system work harder to fight the cancer cells, in this case also fighting the PD-L1 protein.

Do People Survive Triple
In general, about 91% of all women with triple-negative breast cancer are still alive 5 years after diagnosis. If the cancer has spread to the lymph nodes near the breast the 5 year relative survival rate is about 65%. If the cancer has spread to distant places, the 5 year relative survival rate is 12%.
What Are Breast Cancer Subtypes And Why Do They Matter
Your breast cancer subtype is one factor healthcare providers take into account when theyre deciding how to treat your cancer. Thats because not all cancer treatments are successful with all breast cancer subtypes.
Providers look at your cancer cells to identify subtypes. Specifically, they look for molecules on your cells surfaces. These molecules, called receptors, are built to order so only certain substances can climb on and start affecting what your cells do.
Breast cancer cells receptors are open to estrogen and progesterone. Understanding if your breast cancer cells have receptors and if theyre housing hormones helps providers determine how your breast cancer might spread and what treatment might be most effective.
The other type of breast cancer that has another receptor is called her-2 neu. This receptor makes the cells more active, but allows healthcare providers to treat the cancer with specific medicines that target her-2 proteins. If your breast cancer doesnt have her-2 neu and hormone receptors, its called triple negative.

How Is Triple Negative Breast Cancer Diagnosed
The first step might be a mammogram to evaluate a suspicious mass or lump in your breast. Based on what they learn, healthcare providers might perform a biopsy to remove breast tissue. Then they examine the tissues cells to determine the cancer subtype. Identifying the cancer subtype is part of the staging process, which is when providers decide how to treat your cancer.
Sometimes providers use the following tests before treatment to check on your tumors size and whether it has spread, or after treatment to monitor response to treatment:

Triple Negative Breast Cancer Day By Deborah After Breast Cancer Ambassador
Being diagnosed with breast cancer has been one of the most challenging things to live with to date but knowing that Breast cancer isnt just one type of cancer is something everyone should know. There are four main subtypes of breast cancer, with different characteristics, and therefore which require different treatments.
Each year 15 to 20 per cent of patients get diagnosed with Triple-negative breast cancer it is named this because it lacks estrogen, progesterone, and HER2 receptors it accounts for only 10 to 20 per cent of all invasive breast cancers, yet is responsible for a large proportion of breast cancer deaths because it is so aggressive, and is more likely to have already spread to other parts of the body at diagnosis.
Fortunately, Triple-negative breast cancer can be treated with other drugs, such as chemotherapy, radiation therapy and non-HER2 targeted therapy.
Most of us go through chemotherapy, surgery and radiation therapy. Ive had all 3 with 8 rounds of chemo, 2 major surgeries including Lumpectomy and Lymph Node Dissection and Breast Reconstruction.

Causes Of Triple Negative Breast Cancer
The risk factors for triple negative breast cancer are not clear. Some breast cancers depend on hormones to grow. These can be linked with risk factors to do with hormones and having children. But triple negative breast cancer does not seem to share these risk factors.
Most women with triple negative breast cancer have no strong history of breast cancer in their family . But some women with triple negative breast cancer have an altered BRCA1 gene. This will have been inherited from a parent.
An altered BRCA 1 gene can cause breast cancer to run in families. Most breast cancers caused by BRCA1 are triple negative.
If you have triple negative breast cancer, you may be offered genetic testing. This is even if you do not have a family history of breast cancer. Your cancer doctor or breast care nurse can explain more about this to you.
The tests are the same as for any type of breast cancer. You usually have a:
A mammogram is an x-ray of the breast.
- Ultrasound scan
An ultrasound scan uses sound waves to produce a picture of the breast tissue and the lymph nodes in the armpit.
- Breast biopsy
When you have a breast biopsy, your cancer doctor or breast care nurse takes small samples of cells or tissue from your breast. The samples are looked at under a microscope to check for cancer cells. They also do other tests to find out if the cells have receptors for hormones, or for HER2.
The staging and grading is the same as for other types of breast cancer.
What Factors Contribute To The Risk Of Breast Cancer Recurrence
Whilst it is never completely certain that breast cancer has been cured, there are many treatments available that reduce the risk of recurrence. There are a number of risk factors that can contribute to a breast cancer recurrence.
Your age at first diagnosis Younger women, particularly those who had their first diagnosis under the age of 35, have a greater risk of recurrence. This is because those diagnosed at a young age are more likely to have aggressive features in their breast cancer. Additionally women diagnosed with breast cancer before menopause have a greater risk of recurrence.
Tumour size Women who have a larger breast tumour have a greater risk of recurrence.
Lifestyle factors Lifestyle factors can influence the risk of recurrence. Excess weight is associated with a higher risk of postmenopausal breast cancer and is also associated with a higher risk of breast cancer recurrence and death. Smoking has also been shown to increase the risk of recurrence. Women who exercise regularly appear to have a lower rate of breast cancer recurrence.
Lymph node involvement If cancer is found in lymph nodes at the time of the original breast cancer diagnosis, there is an increased risk of breast cancer recurrence. This is the strongest prognostic factor, and the more nodes involved, the higher the risk of recurrence.

Diagnosing Triple Negative Breast Cancer
In many women the cancer is found during breast screening. But symptoms such as a breast lump can be a sign of breast cancer. So it is important to get any symptoms checked by your doctor.
If you have symptoms and see your GP they refer you to a specialist breast clinic. At the breast clinic the doctor or breast care nurse takes your medical history and examines your breasts. They also feel for any swollen lymph nodes under your arms and at the base of your neck.
You have some of the following tests:
- a biopsy your doctor or nurse take a small sample of cells or tissue from your breast to look at under a microscope
Depending on your age and whether other family members have had breast cancer, your doctor might refer you for gene testing. This is to find out if there is a fault in the BRCA cancer gene.

What Is Triple Negative Breast Cancer
A diagnosis of triple negative breast cancer means that the three most common types of receptors known to fuel most breast cancer growthestrogen, progesterone, and the HER-2/neu gene are not present in the cancer tumor. This means that the breast cancer cells have tested negative for hormone epidermal growth factor receptor 2 , estrogen receptors , and progesterone receptors .
Since the tumor cells lack the necessary receptors, common treatments like hormone therapy and drugs that target estrogen, progesterone, and HER-2 are ineffective. Using chemotherapy to treat triple negative breast cancer is still an effective option. In fact, triple negative breast cancer may respond even better to chemotherapy in the earlier stages than many other forms of cancer.

Intrinsic Molecular Subtypes In Tnbc
Distinct molecular portraits of breast cancer, originally identified as Luminal, HER2-Enriched, Basal-like , and Normal-like breast cancer, were based unsupervised gene expression analysis. Luminal A and B subtypes express keratins 8/18 and ER-related gene clusters, the BL has overexpression of keratin 5, 17 and epithelial grown factor receptors -related genes, and the HER2-Enriched subtype is characterized by expression of Erb-B2-related genes each of these molecular subtypes can be found within clinical subsets . About 80% of TNBC are BL, and BL tumors cluster biologically far from the other BC subtypes, making intrinsic subtyping less useful for meaningful subclassification than in the other clinical subtypes. More detailed confirmation of BC heterogeneity has come from multiple efforts to examine DNA, RNA, microRNA, and protein expression patterns through cross-platform analyses such as The Cancer Genome Atlas and METABRIC,.

Stage 3a Breast Cancer
If you are diagnosed with Stage 3A breast cancer, it means that one of the following applies to you:
The tumour is less than 5 cm and breast cancer cells have been found in:
- 4-9 lymph nodes in the armpit. or
- 1 or more lymph nodes under the breastbone
The tumour is larger than 5 cm and breast cancer cells have spread to 1-9 lymph nodes.

Questionable Issues In Tnbcs
TNBCs are known to metastasize via hematogenous routes and this may be in contradiction with the study of Liu previously mentioned, a study which clearly stated that TNBCs have an active lymphangiogenic process which, normally may favour lymphovascular but not hematogenous dissemination. Currently, the molecular features that differentiate or are able to differentiate lymph node positive TNBCs from lymph node negative TNBCs still remain at a hypothetical level and none of them proved to be useful in the clinical and therapeutic approach of TNBCs patients. But most of the TNBCs cancers have preferentially hematogenous metastases. Besides the high mitotic rate and increased nuclear grade, TNBCs also include pushing border of invasion, frequent tumor necrosis and a large central acellular zone . TNBCs usually exhibit a solid/sheet-like growth pattern and may be associated with an increased lymphocytes infiltrate . Despite the fact that these tumors do not usually metastasize through the lymphatic pathways, TNBCs may be characterized by lymphatic invasion and by an increased LVD . However, not all TNBCs are associated with a poor long term survival, although in a low percentage . EGFR, Src kinase pathway and Cdc42-interacting protein 4 are known to promote TNBCs metastasis . CIP4 inhibition seems to decrease the rate of lung metastasis .

Survival Rate For Patients With Triple
Triple-negative breast cancer is considered aggressive, or fast-growing, but it is treatable. Survival depends on factors such as how advanced the cancer was at diagnosis, your overall health, and your response to treatment.
When assessing survival, researchers use a 5-year marker to make predictions about if cancer will reoccur.
According to the American Cancer Society, if any type of breast cancer is found to be stage 1, the 5-year survival rate is nearly 100%. Stage 2 breast cancer survival is about 93%, stage 3 is 72%, and metastasized or grade 4 breast cancer has about a 22% chance of survival. Keep in mind most triple-negative breast cancers are stage 3 when found.
Its important to note that the survival rates may be higher than this data suggests because new treatments are becoming available through clinical research.
