Because the experience of metastatic disease is so different from that of earlier stages, METAvivor has created a separate ribbon to represent metastatic breast cancer. Here is a description of the ribbon from the METAvivor website:
"[In order] to highlight the uniqueness of [metastatic breast cancer] and show its commonality with other stage 4 cancers, METAvivor designed a base ribbon of green and teal to represent metastasis. Green represents the triumph of spring over winter, life over death, and symbolizes renewal, hope, and immortality while teal symbolizes healing and spirituality. The thin pink ribbon overlay signifies that the metastatic cancer originated in the breast."
