Frequently Asked Questions
While not always considered curable in the traditional sense, it is highly treatable, with many patients achieving long-term remission.
It is distinguished by the unique 'hairy' appearance of the cancerous cells under a microscope, its chronic and slow-growing nature, and its specific response to certain targeted therapies.
It is more common in middle-aged to older men, though the exact cause is not well understood.
Patients often present with fatigue due to anemia, frequent infections due to low white blood cells, and easy bruising or bleeding due to low platelets.
