rare tumor
Infrequent malignant mass
A rare tumor is a growth occurring infrequently in the population, typically affecting fewer than 15 per 100,000 people annually.
The designation matters for research funding, treatment protocols, and drug development—rare tumors receive less study and fewer approved therapies than common cancers.
The diagnosis of a rare tumor often means traveling to specialized centers for treatment.
