Metastatic breast cancer is breast cancer that has spread to other parts of the body. At WHAT.EDU.VN, we aim to provide clarity and support to those seeking information. We are here to guide you with the important aspects of metastatic breast cancer, also known as stage IV breast cancer, advanced breast cancer, and secondary breast cancer.
1. Defining Metastatic Breast Cancer: A Comprehensive Overview
Metastatic breast cancer, also referred to as stage IV breast cancer, signifies that the cancer cells have spread from the primary tumor in the breast to distant organs or lymph nodes in other parts of the body. Understanding what metastatic breast cancer truly means is crucial for both patients and their families.
1.1. How Metastasis Occurs
Metastasis is the process where cancer cells detach from the original tumor site. These cells then enter the bloodstream or lymphatic system, allowing them to travel to and form new tumors in other organs. Common sites for breast cancer metastasis include the bones, lungs, liver, and brain.
1.2. Why It’s Still Considered Breast Cancer
Even when breast cancer spreads to other organs, it is still classified and treated as breast cancer. This is because the metastatic tumors are composed of breast cancer cells, which dictate the type of treatment and management strategies used.
1.3. Understanding the Stages of Breast Cancer
Understanding the stages of breast cancer is essential to understanding metastatic breast cancer. The stages indicate the extent of the cancer, which influences treatment decisions and expected outcomes.
| Stage | Description |
|---|---|
| 0 | Cancer is non-invasive and contained within the milk ducts or lobules. |
| I | Cancer is small and hasn’t spread to lymph nodes. |
| II | Cancer is larger or has spread to a few nearby lymph nodes. |
| III | Cancer has spread to many lymph nodes or tissues near the breast. |
| IV | Metastatic breast cancer, where cancer has spread to distant organs like the bones, lungs, liver, or brain. |
2. Signs and Symptoms of Metastatic Breast Cancer
Recognizing the signs and symptoms of metastatic breast cancer is vital for early detection and intervention. The symptoms can vary depending on the location of the metastatic tumors.
2.1. Common Symptoms
