MBC cancer, or metastatic breast cancer, is a type of breast cancer that has spread to other parts of the body, such as the bones, lungs, or brain. It differs from other types of breast cancer in that it is considered Stage IV or advanced breast cancer.
Metastatic breast cancer can occur when cancer cells from the original tumor in the breast break away and travel through the bloodstream or lymphatic system to other parts of the body. While it can occur many years after a person is first diagnosed with breast cancer, it is also possible for it to be diagnosed at the same time as the initial breast cancer diagnosis.
Causes of MBC Cancer
Metastatic breast cancer occurs when cancer cells from the breast spread to other parts of the body, such as the lungs, liver, bones, or brain. While the exact cause of MBC cancer is not fully understood, researchers have identified several factors that may increase a person’s risk of developing this condition.
Factors that can increase the risk of MBC cancer include:
| Factor | Description |
|---|---|
| Age | The risk of breast cancer increases with age, with most cases diagnosed in women over the age of 50. |
| Gender | Women are more likely than men to develop breast cancer. |
| Family history and genetics | A personal or family history of breast cancer, as well as certain genetic mutations, can increase the risk of developing MBC cancer. |
| Hormones | Exposure to estrogen and progesterone, either naturally or through hormone therapy, can increase the risk of developing breast cancer. |
| Lifestyle factors | Factors such as obesity, lack of exercise, and excessive alcohol consumption may increase the risk of developing breast cancer. |
| Previous treatment for breast cancer | Women who have been treated for breast cancer in the past, including lumpectomy or radiation therapy, may have an increased risk of developing MBC cancer. |
It’s important to note that not everyone who has one or more of these risk factors will develop MBC cancer, and many people who develop the disease have no known risk factors.
Genetic Factors
Approximately 10% of MBC cancer cases are due to hereditary factors, including mutations in the BRCA1 and BRCA2 genes. These genes normally help to suppress the growth of cancer cells, but when they are mutated, this function is impaired. Women who have inherited an abnormal BRCA1 or BRCA2 gene have a higher risk of developing breast and ovarian cancer, as well as MBC cancer, in their lifetime.
Symptoms of MBC Cancer
Metastatic breast cancer (MBC) can produce a variety of symptoms that differ from those of early-stage breast cancer. Some of the most common symptoms of MBC cancer are:
- Bone pain and fractures
- Shortness of breath and coughing
- Unexplained weight loss
- Fatigue and weakness
- Jaundice and liver pain
- Headaches, seizures, and confusion (if cancer has spread to the brain)
- Numbness and weakness in the arms or legs (if cancer has spread to the spinal cord or nerves)
It is essential to note that some people with MBC cancer may not exhibit any symptoms at first, which is why regular check-ups and screenings are crucial for early detection. Additionally, symptoms can vary depending on the location and extent of the cancer.
Bone Metastases
Bone metastases are common in MBC cancer, and the pain and discomfort they cause can be intense. A person with bone metastases may experience:
- Persistent bone pain, especially in the back, hips, and ribs
- Difficulty moving around and performing daily activities
- Bone fractures as a result of weakened bones
- Numbness and tingling in the arms or legs
Because bone metastases can be painful and debilitating, it is crucial to manage them appropriately with pain medication and other therapies.
Lung Metastases
MBC cancer can spread to the lungs, causing symptoms such as:
- Shortness of breath, wheezing, and chest pain or discomfort
- Persistent cough or coughing up blood
- Difficulty breathing while lying down
- Fatigue and weakness
Treatment for lung metastases may include radiation therapy or surgery, depending on the location and extent of the cancer.
Diagnosis of MBC Cancer
Diagnosing MBC cancer involves several methods and tests to confirm the presence of cancerous cells that have spread beyond the breast tissue. The diagnostic process typically involves:
- Medical history and physical exam: Your doctor will ask about your medical history and examine your breasts and lymph nodes to check for any abnormalities.
- Imaging tests: These tests use different types of imaging technology to create detailed images of the breast tissue and surrounding areas. Common imaging tests used for diagnosing MBC cancer include:
- Mammography: A type of X-ray that uses low-dose radiation to create an image of the breast tissue.
- Ultrasound: Uses high-frequency sound waves to create an image of the breast tissue and surrounding areas.
- Magnetic resonance imaging (MRI): Uses a powerful magnet to create detailed images of breast tissue.
- Positron emission tomography (PET) scan: A scan that uses a small amount of radioactive material to produce detailed images of the body.
- Biopsy: A biopsy involves removing a sample of breast tissue for analysis under a microscope. There are different types of biopsies, including:
- Core needle biopsy: Uses a long, thin needle to remove a small sample of breast tissue for analysis.
- Surgical biopsy: Involves removing a larger section of breast tissue for analysis. This may be done using traditional surgery or a less invasive procedure, such as a stereotactic biopsy.
- Blood tests: While there is no specific blood test for MBC cancer, blood work can help detect the spread of cancer to other organs in the body.
Once a diagnosis of MBC cancer is confirmed, further tests may be done to determine the stage of the disease. This information helps doctors develop a treatment plan tailored to the individual patient.
If you have any concerns about your breast health or are experiencing symptoms, it’s important to consult with your doctor as soon as possible.
Treatment Options for MBC Cancer
There are several treatment options available for MBC cancer, depending on the individual patient’s condition and preferences. Treatment is often aimed at managing symptoms, improving quality of life, and prolonging survival.
Surgery
Surgery may be used to remove the primary tumor and any surrounding tissue affected by the cancer. In some cases, surgical removal of metastases may also be considered. For some patients, surgery can provide significant relief of symptoms and may help improve overall survival.
Chemotherapy
Chemotherapy involves the use of drugs to kill cancer cells. It can be administered orally or intravenously, and is often used to treat MBC cancer that has spread to other parts of the body. Chemotherapy can be effective in slowing the growth of the cancer, although it can also cause side effects such as fatigue, hair loss, and nausea.
Radiation Therapy
Radiation therapy involves the use of high-energy radiation to kill cancer cells. It can be used to target specific areas of the body affected by the cancer, and may be used in combination with other treatments such as chemotherapy and surgery. Radiation therapy can be effective in controlling symptoms such as pain and swelling, but can also cause side effects such as fatigue and skin irritation.
Targeted Therapy
Targeted therapy involves the use of drugs that specifically target cancer cells, while sparing normal cells. This can help to reduce side effects associated with other treatments, such as chemotherapy. Targeted therapies may be used alone or in combination with other treatments, and may be more effective for certain types of MBC cancer.
Hormone Therapy
Hormone therapy involves the use of drugs to block or reduce the amount of hormones that promote the growth of certain types of MBC cancer. It can be effective in slowing the growth of the cancer and improving survival rates. Hormone therapy is typically used for MBC cancer that is hormone receptor positive.
It is important to note that the choice of treatment will depend on many factors, such as the stage of the cancer, the location of the metastases, the patient’s overall health, and their personal preferences. It is recommended that patients discuss treatment options with their healthcare provider to determine the best course of action for their individual situation.
Prognosis for MBC Cancer
The prognosis for MBC cancer can vary widely depending on a number of factors, including the stage of the disease, the location of the metastases, and the effectiveness of treatment.
The Importance of Early Detection
Early detection is key when it comes to MBC cancer. The earlier the cancer is detected and treated, the better the prognosis tends to be. In general, the 5-year survival rate for MBC cancer is lower than for other types of breast cancer, but this can vary depending on the stage of the disease at diagnosis.
Survival Rates
According to the American Cancer Society, the 5-year survival rate for metastatic breast cancer is around 27%. However, this number can vary depending on a number of factors, including the stage of the disease and the type of treatment received.
For example, the 5-year survival rate for women with early-stage MBC cancer is around 69%, while the 5-year survival rate for those with advanced-stage MBC cancer is around 13%. However, it’s important to remember that survival rates are just one factor in determining the overall outlook for a patient with MBC cancer.
Treatment Effectiveness
The effectiveness of treatment is another important factor that can influence the prognosis for MBC cancer. Different treatments may be more or less effective depending on the individual patient and the stage of the disease. In general, targeted therapies tend to be more effective than chemotherapy for MBC cancer, but this can vary depending on the specific case.
Individual Factors
Beyond stage, location, and treatment, there are also a number of individual factors that can influence the prognosis for MBC cancer. These may include age, overall health, and the presence of other medical conditions. Patients with a strong support system and a positive outlook may also have a better prognosis than those who lack these resources.
Ultimately, it is difficult to predict the prognosis for any individual patient with MBC cancer. While survival rates and other statistics can be helpful in understanding the general outlook for the disease, each individual case is unique and may be influenced by a range of different factors.
Stages of MBC Cancer
Metastatic breast cancer can be divided into different stages, based on the extent to which the cancer has spread throughout the body. The stage of the cancer will determine the course of treatment and the overall prognosis for the patient. The following are the four main stages of MBC cancer:
Stage I
| Features | Description |
|---|---|
| Extent of metastasis | The cancer has spread to one distant site, such as the lungs or bones. |
| Treatment options | Treatment may include surgery, radiation therapy, and/or systemic therapy such as chemotherapy or hormone therapy. |
| Prognosis | The five-year survival rate for stage I MBC cancer is approximately 20-40%. |
Stage II
| Features | Description |
|---|---|
| Extent of metastasis | The cancer has spread to two or more distant sites, such as the lungs and bones. |
| Treatment options | Treatment will typically include systemic therapy, such as chemotherapy or hormone therapy. |
| Prognosis | The five-year survival rate for stage II MBC cancer is approximately 10-20%. |
Stage III
| Features | Description |
|---|---|
| Extent of metastasis | The cancer has spread to multiple distant sites, such as the lungs, liver, and bones. |
| Treatment options | Treatment will typically include systemic therapy, such as chemotherapy or hormone therapy. |
| Prognosis | The five-year survival rate for stage III MBC cancer is approximately 5-10%. |
Stage IV
| Features | Description |
|---|---|
| Extent of metastasis | The cancer has spread to multiple distant sites and is considered advanced. |
| Treatment options | Treatment will typically focus on managing symptoms and improving quality of life, rather than curing the cancer. |
| Prognosis | The five-year survival rate for stage IV MBC cancer is approximately 22%. |
It’s important to note that the prognosis for MBC cancer can vary widely depending on a range of factors, including the stage of the disease, the location of metastases, and the effectiveness of treatment. While these statistics can be helpful in understanding the general outlook for those with MBC cancer, they should be viewed as estimates rather than definitive predictions.

MBC Cancer Myths and Misconceptions
Despite advances in medical research and understanding, there are still many myths and misconceptions surrounding Metastatic Breast Cancer (MBC). These beliefs can often lead to confusion, fear, and stigma for those living with the disease. Here we debunk some of the most common myths and provide accurate information about MBC.
Myth: Early detection is a guarantee against MBC.
While early detection of breast cancer can improve the chances of successful treatment and reduce the risk of recurrence, it is not a guarantee against MBC. Some breast cancers may already be metastatic at the time of diagnosis, and others may recur as MBC even after successful treatment.
Myth: MBC is a death sentence.
While there is currently no cure for MBC, treatment options have improved significantly in recent years, and many people are able to live with the disease for many years. Some people may even experience long-term remission. Advances in research and treatment continue to offer hope for improved outcomes.
Myth: MBC only affects older women.
While the risk of developing breast cancer, including MBC, does increase with age, women (and men) of any age can develop the disease. It is important for everyone to be aware of the signs and symptoms of breast cancer and to advocate for their healthcare needs.
Myth: MBC only affects the breast.
While breast cancer is typically associated with the breast tissue, MBC means that the cancer has spread to other parts of the body, such as the bones, liver, lungs, or brain. This can cause a wide range of symptoms and complications that are not limited to the breast.
Myth: MBC is contagious.
MBC is not contagious and cannot be spread from person to person through physical contact or other means. The causes of MBC are still not fully understood, but it is generally believed to arise from a combination of genetic and environmental factors.
Myth: Women with MBC cannot have children.
While treatment for MBC can have an impact on fertility, many women with MBC are able to have children before and after diagnosis. It is important for women to discuss their reproductive options with their healthcare team and to make informed decisions about their care.
