A study hypothesized that intercellular communication of tumor exosomes could mediate further regions of metastasis for cancer. Hypothetically, exosomes can plant tumor information, such as tainted RNA, into new cells to prepare for cancer to travel to that organ for metastasis. The study found that tumor exosomal communication has the ability to mediate metastasis to different organs. Furthermore, even when tumor cells have a disadvantage for replicating, the information planted at these new regions, organs, can aid in the expansion of organ specific metastasis.
