What is haematology? 

Haematology is involved in the extensive research, diagnosis, treatment, and prevention of blood, bone marrow, and lymphatic system diseases. As such, haemotologists carry with them the specialised knowledge to deal with an array of complex issues related to the blood, blood cells, white blood cells, platelets, blood vessels, bone marrow, lymph nodes, spleen, and the proteins that aid in blood clotting. The health and life of the human body depends vitally on these components, as they play many essential roles in the bodily functions, such as transporting nutrients and oxygen to all of our body parts as well as protecting our body against infection. Disorders and cancers of the blood, bone marrow, and lymphatic system could lead to very adverse health effects and therefore, require very delicate, highly skilled, and efficient medical procedure. At Beacon Hospital, we have an elite team of haematologists at the top of their field. It is a department with up-to-date research and innovation at its core, so as to deliver the latest, state-of-the-art treatment for every haematologic disease out there.
