If you have breast cancer and it is only in your breast it is kind of like a bag of flour. So treatment will focus on getting that bag of flour out (surgery, chemo, radiation). If the breast cancer has spread it beyond the breast it is still breast cancer – but now elsewhere in your body too. It is like the bag of flour burst. Instead of one location to focus on it is much more difficult to find all the individual pieces of flour (cancerous cells) and the treatment becomes more complex and harder.
