Some information, from the Children's Oncology group, around the type of Leukemia "“ cancer of the blood, that Malyka is suffering from.
Acute lymphoblastic leukemia (ALL) is a "liquid" tumor or cancer of the blood that starts in the bone marrow and spreads to the bloodstream (the term leukemia comes from Greek words for white and blood). ALL is the most common children's cancer, accounting for 35% of all cancers in children. There are about 2,900 new cases of ALL diagnosed in children and adolescents (0-21 years old) in the United States each year.
Symptoms: It is the decrease in normal cells that produces many of the symptoms of ALL
"¢ Fatigue and being pale results from a decreased number of red blood cells, known as anemia
"¢ Fever due to the disease itself or from infection because there are a decreased number of healthy white blood cells, known as neutropenia
"¢ Bruising or bleeding from decreased platelets, known as thrombocytopenia
"¢ Bone pain, sometimes associated with swelling of the joints
The signs and symptoms of ALL can be the same as more common children's illnesses and many children are treated for those other illnesses before leukemia is diagnosed. Most children with ALL have symptoms for a few weeks to several months before a diagnosis of cancer is made.
