Yes, pseudomyxoma peritonei (PMP) is considered a type of cancer. It is a rare cancer that usually starts in the appendix and can spread to the peritoneum, which is the lining of the abdominal cavity. The cancer cells in PMP produce a jelly-like substance called mucin, which can fill the abdominal cavity and cause a range of symptoms. While PMP is considered a type of cancer, it is often treated differently from other types of cancer due to its unique characteristics and behaviour.

It’s worth noting that PMP is usually classified as a low-grade malignancy, meaning that it is considered a form of cancer but is often slow-growing and not as aggressive as other types of cancer.
