What is Triple Negative (TNBC) Cancer?

Triple Negative Breast Cancer refers to a subtype
of breast cancer where the tumor cells lack all three receptors commonly found in other breast cancers—these are
estrogen receptors (ER), progesterone receptors
(PR), and human epidermal growth factor receptor 2
(HER2). These receptor statuses are typically used to
guide treatment, meaning TNBC requires a different therapeutic
approach due to their absence.

Because TNBC lacks the receptors used by hormone therapy and HER2-targeted medicines, treatment planning often depends on stage, tumor characteristics, genetic findings, prior treatment and response to therapy.

What Does “Triple Negative” Mean for Breast Cancer?

When breast cancer is classified as “triple negative,” it signifies that the cancer does not respond to hormonal therapy
or medicines that target (HER2) receptors. This is because
the cancerous cells do not have the three respective receptors that such treatments normally target.

How Common is Triple Negative Breast Cancer?

Triple Negative Breast Cancer accounts for about 10-15% of all breast cancer diagnoses. This subtype is less common than
other forms of breast cancer but tends to be more aggressive and has a higher risk of recurrence, especially within the
first 3-5 years after treatment. At Sunridge Medical,
our commitment is to provide patients with comprehensive information and options for managing their condition. Should
you have any further inquiries regarding TNBC or other health
concerns, please consult with one of our physicians and speak to our Patient Care Team at
1-800-923-7878.

Triple Negative Breast Cancer Treatment Options

Treatment for Triple Negative Breast Cancer depends on the stage of the cancer, tumor characteristics, genetic findings, previous treatment and the patient’s overall health. Conventional treatment may include surgery, chemotherapy and radiation. Depending on the individual case, immunotherapy or other targeted approaches may also be considered.

Because TNBC can behave differently from other breast cancer subtypes, patients may benefit from reviewing the complete treatment picture rather than relying on receptor-directed therapies that are used for ER-positive, PR-positive or HER2-positive disease.

Sunridge Medical works with patients who are newly diagnosed as well as patients who are already receiving treatment, have completed treatment, or are looking for additional supportive and integrative options.

Triple Negative Breast Cancer Risks, Causes and Fuels

How Do You Get Triple Negative Breast Cancer?

Cancer is a complex, multifactorial disease, and while several risk factors have been identified, there is no singular
way to “get” cancer. For TNBC, genetic predisposition can be a
factor, as can other lifestyle and environmental elements. A comprehensive, well-balanced approach to health, including
regular screenings and maintaining a healthy lifestyle, can help reduce the risk of not only
TNBC but various other diseases as well.

Is Triple Negative Breast Cancer the Worst Cancer You Can Get?

While it’s not accurate to label any cancer as the “worst,” Triple Negative Breast Cancer (TNBC</abbr >) is known to be a more aggressive form of breast cancer with fewer targeted treatment options currently available. It
tends to grow and spread faster than other types of breast cancer, leading to a perception that it is particularly
challenging. However, ‘worst’ is a subjective term and outcomes can vary based on a variety of factors including the
stage at diagnosis and overall health.

Is Triple Negative Breast Cancer Genetic?

Triple Negative Breast Cancer is not generally considered genetic; however, a subset of patients with
TNBC carry inherited gene mutations such as BRCA1 and BRCA2, which
can increase an individual’s risk of developing it. Therefore, it is important for patients with a strong family history
of breast or ovarian cancer to consider genetic testing.

Can Triple Negative Breast Cancer Be Hereditary?

Genetic susceptibility plays a significant role in some cases of
TNBC. Women with a BRCA1 mutation are at a higher risk of developing
TNBC, and in those cases, the disease is more likely to occur at a
younger age. While not all Triple Negative Breast Cancer is hereditary, understanding your family history and
considering genetic testing can be important for tailored cancer management and potential preventive measures.

Is Triple Negative Breast Cancer Hereditary?

Although Triple-Negative Breast Cancer is not inherently hereditary, mutations in BRCA1 and BRCA2 genes, which can be
inherited from one’s parents, are linked to a higher risk of developing
TNBC. Therefore, it can be hereditary in cases where these genetic
mutations are present. Patients with a family history of breast cancer, particularly
TNBC, should discuss genetic testing with their healthcare provider
for a more accurate assessment of their risk.

What Fuels Triple-Negative Breast Cancer?

The growth and spread of Triple-Negative Breast Cancer are not fueled by estrogen, progesterone, or
(HER2) receptors, hence why it does not respond to
hormonal therapies. The absence of these receptors leads researchers to investigate other pathways and factors that
might contribute to the development and growth of TNBC. Factors such
as genetic mutations, younger age, ethnicity, obesity, environmental factors, and high tumor grade are associated with
TNBC.

What Causes Triple Negative Breast Cancer?

The exact causes of Triple Negative Breast Cancer is not fully understood. However, certain risk factors have been
identified, including inherited genetic mutations (particularly BRCA1 and BRCA2), hormonal factors, prevalence in
younger women and specific ethnic groups, obesity, and exposure to certain environmental toxins. Researchers continue to
explore how these factors might contribute to the development of
TNBC.

Is Ductal Carcinoma in Situ (DCIS) Ever Triple Negative Breast Cancer?

DCIS is a non-invasive cancer that starts in the milk ducts and is the
most common type of non-invasive breast cancer. It’s important to note that
DCIS can become invasive, including invasive Triple Negative Breast
Cancer. While most DCIS cases are not triple negative, a fraction develops
into TNBC, highlighting the need for vigilant follow-up care and
monitoring.

Can Lobular Breast Cancer Be Triple Negative Breast Cancer?

Lobular breast cancer arises in the lobules, or the milk-producing glands, and can be either invasive or in situ. While
TNBC is more frequently associated with ductal carcinoma (85-90% of
all breast cancers), lobular breast cancer can also present as TNBC,
although less often. This underscores the diversity within TNBC and
the need for distinct approaches to diagnosis and treatment.

Can Pregnancy Cause Triple Negative Breast Cancer?

Pregnancy-related breast cancer is a complex field. While being pregnant is not a direct cause of
TNBC, hormonal changes during pregnancy can contribute to the
development or progression of breast cancer. Research is ongoing to understand the specifics, but at this time, no
definitive link has been established between pregnancy and a higher risk of Triple Negative Breast Cancer.

Does Smoking Cause Triple Negative Breast Cancer?

Smoking has been linked to numerous cancers, primarily lung cancer. However, research about the link between smoking and
breast cancer, especially TNBC, is less clear-cut. While no direct
causation has been established, smoking is a risk factor for cardiovascular disease, and it’s advisable to avoid smoking
as part of a general healthy lifestyle that may also reduce cancer risk.

Can Stress Cause Triple Negative Breast Cancer?

The relationship between stress and cancer, including TNBC, is a
topic of ongoing research. Chronic stress is associated with physiological changes that can affect the body’s immune
response, potentially influencing cancer development or progression. Stress-reduction techniques, combined with standard
cancer care, are often recommended to enhance overall well-being for patients diagnosed with
TNBC.

Can Sun Exposure Cause Triple Negative Breast Cancer?

Sun exposure is a well-known risk factor for skin cancer, but its association with breast cancer, including
TNBC, is still not fully understood. While a lack of vitamin D, which
is synthesized in the body upon sun exposure, has been suggested as a potential risk factor for breast cancer, direct
causation has not been established. Balancing sun exposure with appropriate protection against skin damage with UVA and
UVB sunscreens is crucial for good health.

Diagnosis and Misdiagnosis of Triple Negative Breast Cancer (TNBC)

Can Triple Negative Breast Cancer Be Misdiagnosed?

Yes, TNBC can sometimes be misdiagnosed, particularly in its initial
stages. Call our Patient Care Team at 1-800-923-7878 to schedule with Sunridge
Medical. This type of breast cancer is known for being aggressive and may share characteristics with other subtypes,
which poses a challenge in accurate diagnosis. Misdiagnosis can occur due to various reasons such as:

1. Overlapping features with other cancers that lead to difficulty in distinguishing
   TNBC from other subtypes.
2. Suboptimal biopsy techniques or sample errors that may not accurately represent the tumor’s pathology.
3. Interpretation errors during pathological examination where hormone receptor status might be misclassified.
4. Insufficient tumor markers or unclear clinical presentations that create diagnostic uncertainty.

It is critical that the diagnosis of TNBC is confirmed through
comprehensive pathologic evaluation including immunohistochemical staining for estrogen receptor
(ER), progesterone receptor progesterone receptors
(PR), and
(HER2)/neu, along with a detailed medical history and
appropriate imaging studies. If there is a concern about the accuracy of your diagnosis, it is always prudent to pursue
a second opinion.

Can Triple Negative Breast Cancer Become Estrogen Positive?

TNBC is characterized by the lack of estrogen receptors, progesterone
receptors, and (HER2) protein. It is highly unlikely for
TNBC to convert into an estrogen receptor-positive status.
TNBC‘s biological behavior is defined by the absence of these
receptors, and this typically remains consistent over the course of the disease.

Can Triple Negative Breast Cancer Change to Positive?

The defining trait of TNBC is the absence of three key
receptors—hence the term “triple-negative.” This particular profile means that
TNBC doesn’t typically “change” to positive for
(ER), progesterone receptors (PR), or
(HER2) status over time. Treatment responses and patterns
of recurrence for TNBC are more closely associated with the unique
molecular and genetic characteristics of the cancer rather than switching to another receptor status.

Can I Get a Second Opinion of My TNBC Cancer?

Absolutely. A second opinion can offer you peace of mind and confirm the diagnosis and recommended treatment plan. In
matters of health, and particularly with something as serious as
TNBC, it’s important to feel confident in your care approach.
Gathering insights from another oncologist or a specialist center familiar with
TNBC can ensure you have considered all perspectives and treatment
options. At Sunridge Medical, we welcome patients seeking a second opinion, and we’re dedicated to providing thorough
evaluations to inform your treatment decisions.  Call our Patient Care Team to set an appointment for a second opinion
at 1-800-923-7878.

Remember, it’s important to consult with healthcare professionals if you have been diagnosed with Triple Negative Breast
Cancer or if you have any concerns about your diagnosis. An accurate and timely diagnosis is crucial for effective
treatment and improved outcomes.

Get a Second Opinion for Triple Negative Breast Cancer

A second opinion can help you better understand your receptor status, stage, pathology, genetic or molecular testing, previous treatment and questions about what options may remain. Bring your pathology reports, imaging, treatment history and current medications so the Sunridge team can review the complete picture.

Metastasis and the Spread of Triple Negative Breast Cancer

Metastatic Triple Negative Breast Cancer

When TNBC has spread beyond the breast, treatment decisions depend on where the cancer has spread, previous therapies, current symptoms, tumor characteristics and the patient’s overall health. Patients with metastatic TNBC may have already received several lines of treatment and may be looking for another opinion about available options.

Talk With Our Cancer Care Team About Your Treatment History

Metastatic Triple Negative Breast Cancer is a particularly aggressive type of cancer that lacks the three receptors
commonly found in breast cancers—estrogen, progesterone, and
(HER2). Metastatic refers to the cancer having spread from
its original region to other parts of the body. Given its nature, this type of breast cancer does not respond to typical
hormone therapies or drugs targeting (HER2), and as a
result, requires more complex treatment strategies.

Where Does Triple Negative Breast Cancer Spread?

Triple negative breast cancer can spread to any part of the body, but common areas include the lungs, liver, brain, and
bones. The spread of cancer, known as metastasis, is a serious complication that can make treatment and management more
difficult. Does Triple Negative Breast Cancer Always Come Back? While Triple Negative Breast Cancer does have a higher
risk of recurrence within the first few years following treatment, it does not always recur. The exact risk depends on
various factors, including the stage at which the cancer was diagnosed and the treatments received.

Can Triple Negative Breast Cancer Come Back After Mastectomy?

Although a mastectomy significantly reduces the local recurrence of breast cancer, it does not completely eliminate the
risk. Triple negative breast cancer may recur elsewhere in the body, even after a mastectomy. Recurrence risk is
influenced by whether the cancer had spread to the lymph nodes or other parts of the body before the mastectomy.

Can Triple Negative Breast Cancer Spread?

Yes, like other forms of cancer, Triple Negative Breast Cancer has the potential to spread. This can happen if cancer
cells break away from the original tumor and travel through the bloodstream or lymphatic system to other parts of the
body.

Can Triple Negative Breast Cancer Spread to the Bones?

Yes, Triple Negative Breast Cancer TNBC can metastasize to the bones.
This process, referred to as bone metastasis, is one of the more frequent pathways by which breast cancer can spread.
Patients experiencing bone metastasis may encounter symptoms including persistent bone pain, an increased susceptibility
to fractures, and elevated calcium levels that can lead to further health complications. Patients should report any new
or unusual symptoms to their healthcare provider as soon as possible for evaluation. Bone scans or other imaging
technologies may be utilized to identify metastases. Treatments may be prescribed to manage symptoms and prevent
complications.

Can Triple Negative Breast Cancer Spread to the Brain?

Triple-negative breast cancer has the potential to spread to the brain, which is known as brain metastasis. Though not
as common compared with other subtypes of breast cancer, TNBC’s ability to spread to the brain is a significant concern
due to the aggressiveness associated with TNBC. Symptoms of brain
metastasis might include persistent headaches, seizures, changes in vision, difficulty with balance, and alterations in
cognitive or behavioral functions. It’s important for patients to inform their healthcare provider about any
neurological symptoms to initiate appropriate diagnostic testing and treatment modalities as soon as possible.

Can Triple Negative Breast Cancer Spread to the Heart?

Metastatic spread of Triple Negative Breast Cancer (TNBC) to the
heart itself is extremely rare. While TNBC can spread through the
bloodstream to various distant organs, direct metastasis to the heart is not common. However, breast cancer and its
treatments can indirectly affect heart health. For instance, some cancer therapies may have an adverse impact on
cardiovascular functioning, so it is essential for patients to discuss potential risks and management strategies with
their healthcare team. Regularly scheduled monitoring and comprehensive care that addresses all aspects of the patient’s
health, including heart health, are integral parts of a thorough cancer treatment plan. Patients should stay vigilant
regarding any cardiovascular symptoms and communicate openly with their healthcare provider to ensure the best possible
outcomes.

Prognosis and Survival Rates of Triple Negative Breast Cancer

Can You Survive Triple Negative Breast Cancer?

Triple Negative Breast Cancer can have different outcomes depending on the stage of the cancer, tumor characteristics, response to treatment, overall health, and other individual clinical factors. Advances in breast cancer treatment continue to provide patients with additional treatment options, but prognosis is different for every patient.

Discuss your individual prognosis and treatment options with your oncology team.

Does Triple Negative Breast Cancer Always Return?

Triple Negative Breast Cancer does not always return after treatment. The risk of recurrence can vary based on factors such as the stage of the cancer, tumor characteristics, treatment received, and how the cancer responded to treatment. Regular follow-up care can help your healthcare team monitor your health and address new or concerning symptoms.

Discuss your individual prognosis and treatment options with your oncology team.

Discuss your individual prognosis and treatment options with your oncology team.

Symptoms of Triple Negative Breast Cancer (TNBC) and Skin Concerns

What does Triple Negative Breast Cancer Look Like?

Triple Negative Breast Cancer does not have a unique physical appearance that differentiates it from other types of
breast cancer when observed externally. It is characterized by the absence of estrogen receptors
(ER), progesterone receptors progesterone receptors
(PR), and the
(HER2) protein on the cancer cells. These traits mean it
is frequently more aggressive and challenging to treat than other breast cancer types, but these differences are at a
molecular level rather than a visual one. The outward visible symptoms of breast cancer like lumps, changes in breast
size or shape, dimpling or puckering of the skin, nipple retraction, or skin irritation can be similar across various
breast cancer types, including TNBC.

Why Does TNBC Cause Skin Problems?

Skin changes in patients with Triple Negative Breast Cancer can have different causes. Some changes may be related to the cancer itself, while others may occur as a side effect of treatment or from other skin conditions.

• Direct Involvement: In some cases, breast cancer can affect nearby skin tissue and may cause changes such as redness, swelling, nodules, irritation, or ulceration.

• Treatment Side Effects: Chemotherapy, radiation and other cancer treatments may cause skin dryness, rashes, itching, sensitivity or other skin changes.

• Skin Infections or Wound Problems: Patients receiving cancer treatment may experience skin or wound-related problems that require evaluation and appropriate care.

Patients should report any new, worsening, painful, or unusual skin changes to their healthcare provider so the cause can be evaluated and treated appropriately.

What Can Be Done to Help with the Skin Problems of TNBC?

Managing skin issues related to TNBC involves a multi-faceted
approach:

• Medical Management: Work with your healthcare team to address skin infections proactively and manage any drug
  reactions or skin side effects resulting from cancer treatments.

• Nutritional Support: Adequate nutrition supports skin health. Increase intake of foods high in vitamins,
  minerals, and antioxidants that promote skin healing. Stay hydrated.

• Wound Care: Proper care for any wounds, using sterile techniques and appropriate dressings, is critical in
  facilitating skin healing and preventing infections.

• Specialized Dermatologic Interventions: In some cases, dermatologists may prescribe medicated creams, ointments,
  or procedures to manage specific skin issues.

It is essential to communicate regularly with your healthcare provider about any new or worsening skin problems so they
can propose a plan that accommodates your individual needs throughout your treatment for
TNBC. If you need additional care, please call Sunridge Medical at
1-800-923-7878.
