Rarity does in many cases mean a lower chance of survivability, however grey zone lymphoma does have a high chance of first round survivability. Unfortunately there's a high chance of relapse.
yea thats just for cancer, obviously if theres tumors in central organs the cancer can metastasise easily. Im talking about rarity for bacterial and viral infections which is the complete opposite.
People don't understand cancer properly. People mostly associate prognosis with site of cancer rather than what types of cells are involved, how much differentiation is there or depth of invasion, their metastatic properties and response to chemo/radio .
