CancerIndex

CancerIndex is a research and information platform. It is not a physician, does not diagnose, and does not recommend treatment. Population statistics do not predict individual outcomes.

Every number links to its source and retrieval date. Derived metrics carry a formula version. AI-generated synthesis is not enabled in this phase; all content is database-grounded.

Definition

What this entity is

Primary myelofibrosis characterized by bone marrow hypercellularity and the presence of atypical megakaryocytes. There is no increase in the percentage of myeloblasts and no significant increase in reticulin or collagen fibrosis in the bone marrow.

Key figures

At a glance

Each figure carries its unit, period and source; ranks link to "Why this rank?".

No registry-level ancestor: burden figures are published for the mutually exclusive top-level site groups only, and this entity does not descend from one. Global figures (IARC / GLOBOCAN) stay under license review and SEER awaits credentials.
