In this condition, the bone marrow becomes scarred and fibrous, leading to disruption in the production of blood cells.<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Myelofibrosis originates from the malfunctioning of stem cells in the bone marrow.<\/li>\n\n\n\n<li>Over time, the bone marrow loses its ability to produce an adequate number of blood cells.<\/li>\n\n\n\n<li>The condition can occur spontaneously or as a progression from other <b><u><a href=\"https:\/\/www.drkarunhematology.com\/myeloproliferative-neoplasms.html\" target=\"_blank\" rel=\"noreferrer noopener\">myeloproliferative neoplasms<\/a><\/u><\/b> (MPNs). For example, essential thrombocythemia or polycythemia vera.<\/li>\n\n\n\n<li>Myelofibrosis can affect individuals of any age. However, it is more common in older adults, with the average age of diagnosis being around 65 years old.<\/li>\n\n\n\n<li>While myelofibrosis is considered a rare disease, its prevalence may be underestimated due to misdiagnosis or underreporting.<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">Learning the basics of myelofibrosis sets the stage for exploring its causes and symptoms comprehensively.<\/p>\n\n\n\n<figure class=\"wp-block-embed is-type-video is-provider-youtube wp-block-embed-youtube wp-embed-aspect-16-9 wp-has-aspect-ratio\"><div class=\"wp-block-embed__wrapper\">\n<iframe loading=\"lazy\" title=\"Myelofibrosis symptoms and Treatment | \u092e\u093e\u092f\u0932\u094b\u092b\u093e\u0907\u092c\u094d\u0930\u094b\u0938\u093f\u0938  | Dr. Karuna Kumar\" width=\"840\" height=\"473\" src=\"https:\/\/www.youtube.com\/embed\/DZcmBMA_cRE?feature=oembed\" frameborder=\"0\" allow=\"accelerometer; autoplay; clipboard-write; encrypted-media; gyroscope; picture-in-picture; web-share\" referrerpolicy=\"strict-origin-when-cross-origin\" allowfullscreen><\/iframe>\n<\/div><\/figure>\n\n\n\n<h2 class=\"wp-block-heading\"><strong>Causes of Myelofibrosis<\/strong><\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">While the exact cause of myelofibrosis remains unclear, several factors contribute to its development.
