With increasing survival rates for many types of childhood cancers, some of these cancers are approaching cures. Several key events have made this possible.

Many people consider living near traffic to be dangerous for children, fearing accidents. New research suggests that traffic can be harmful to children for other reasons.

Chemotherapy is a standard treatment for the most common form of leukemia — chronic lymphocytic leukemia (CLL). A combination of pills may offer CLL patients new, better and gentler options.

Many leukemias can be treated successfully, but if the disease doesn’t respond, patients are left with few options. A new therapy may change all that.

While leukemia treatments can be uncomfortable, they also save lives. Still, reducing the discomfort of these treatments remains important, especially for the youngest patients.

Myelofibrosis is a type of chronic leukemia that attacks bone marrow. Researchers at Mayo Clinic showed promising study results for one treatment for this disease.

A medication taken off the market in 2010 may have a new use in treating children with an aggressive form of blood cancer.

Therapies that are successful in wiping out childhood leukemia can impact the health of survivors years down the road. New research found that heart problems can begin to appear in survivors even during childhood.

Thanks to treatment advances, the vast majority of children diagnosed with leukemia are living well into adulthood. But the powerful treatment, while effective against the cancer, can cause some health problems later in life. A new study looked at the treatment-related effects on survivors’ mental functions.

The US Food and Drug Administration (FDA) has asked the maker of a medication that has been used to treat two types of leukemia to stop selling that product.
