Prognosis:Metastatic breast cancer isn't the same for everyone who has it. According to the National Breast Cancer Foundation (NBCF), your symptoms at stage 4 will depend on the degree to which the cancer has spread in your body.
Although metastatic breast cancer has no cure, it can be treated. Receiving proper treatment can increase both your quality of life and your longevity.
Metastasised:
To understand the prognosis for stage 4 breast cancer, it helps to know something about the process of metastasis. When cancer "metastasizes," it has spread beyond the part of the body where it originated. In the case of breast cancer, receiving a stage 4 diagnosis may mean the cancer has reached your bones, lungs, liver, or even your brain.
Stage 4 Breast Cancer:If you've been told that you have metastatic breast cancer, this means that the cancer has advanced to what's known as "stage 4."
Stage 4 breast cancer is defined as having spread beyond the breast tissue into other areas of the body.
