Leukemia
A group of blood and bone-marrow cancers where the exact subtype (AML, ALL, CML, CLL) drives everything — from urgency of treatment to whether transplant is needed.
What to know first
- Acute leukemias (AML, ALL) need same-week treatment; chronic ones (CLL, CML) may be watched.
- Cytogenetics and molecular markers (FLT3, NPM1, BCR-ABL, IDH) shape drug choice.
- Targeted therapies have dramatically improved outcomes for many subtypes.
When to see a doctor
- Unexplained fatigue, easy bruising, or frequent nosebleeds
- Frequent or unusual infections
- Persistent bone pain, night sweats, or unexplained weight loss
