Many people have asked me to explain what Metastatic Breast Cancer is and what it means for my future. There are a lot of misconceptions out there as to what a stage 4 MBC diagnosis means. The information below is an excellent explanation, that is clear and easy to understand. I previously posted an article specifically about the Myths and Misconceptions About Metastatic Breast Cancer which highlighted many of the questions that I have been asked since being diagnosed back in March.
Metastatic breast cancer {also called stage IV} is breast cancer that has spread beyond the breast and nearby lymph nodes to other parts of the body. Although metastatic breast cancer has spread to another part of the body, it’s still breast cancer and treated as breast cancer.
The most common breast cancer metastasis sites are the bones, the lungs, the brain, and the liver. The symptoms of metastatic breast cancer can be very different depending on the location of the cancer cells.
Bone Metastasis: Symptoms and Diagnosis
The most common symptom of breast cancer that has spread to the bone is a sudden, noticeable new pain. Breast cancer can spread to any bone, but most often spreads to the ribs, spine, pelvis, or the long bones in the arms and legs.
Lung Metastasis: Symptoms and Diagnosis
When breast cancer moves into the lung, it often doesn’t cause symptoms. If a lung metastasis does cause symptoms, they may include pain or discomfort in the lung, shortness of breath, persistent cough, and others.
Brain Metastasis: Symptoms and Diagnosis
Symptoms of breast cancer that has spread to the brain can include headache, changes in speech or vision, memory problems, and others.
Liver Metastasis: Symptoms and Diagnosis
When breast cancer spreads to the liver, it often doesn’t cause symptoms. If a liver metastasis does cause symptoms, they can include pain or discomfort in the mid-section, fatigue, and weakness, weight loss or poor appetite, fever, and others.
Cancer cells can break away from the original tumor in the breast and travel to other parts of the body through the bloodstream or the lymphatic system, which is a large network of nodes and vessels that works to remove bacteria, viruses, and cellular waste products.
Breast cancer can come back in another part of the body months or years after the original diagnosis and treatment. Nearly 30% of women diagnosed with early-stage breast cancer will develop metastatic disease.
Some people have metastatic breast cancer when they are first diagnosed with breast cancer (called “de novo metastatic”). This means that the cancer in the breast wasn’t detected before it spread to another part of the body.
A metastatic tumor in a different part of the body is made up of cells from the breast cancer. So if breast cancer spreads to the bone, the metastatic tumor in the bone is made up of breast cancer cells, not bone cells.
Being diagnosed with metastatic breast cancer can be overwhelming. You may feel angry, scared, stressed, outraged, and depressed. Some people may question the treatments they had or may be mad at their doctors or themselves for not being able to beat the disease. Others may deal with the diagnosis of metastatic breast cancer in a matter-of-fact way. There is no right or wrong way to come to terms with the diagnosis. You need to do and feel what is best for you and your situation.
Keep in mind that metastatic disease is NOT hopeless. Many people continue to live long, productive lives with breast cancer in this stage. There are a wide variety of treatment options for metastatic breast cancer, and new medicines are being tested every day. More and more people are living life to the fullest while being treated for metastatic breast cancer.
While metastatic breast cancer may not go away completely, treatment may control it for a number of years. If one treatment stops working, there usually is another one you can try. Cancer can be active sometimes and then go into remission at other times. Many different treatments alone, in combination, or in sequence are often used. Taking breaks in treatment when the disease is under control and you are feeling good can make a big difference in your quality of life.
