What caused the cancer? Was it caused by something I did…
or drank, ate, was exposed to, something that happened in utero?

In almost all cases, we don't know the cause. We know that in adults, lung cancer is associated with smoking, that mesothelioma is associated with prolonged asbestos exposure, and that sun exposure can cause skin cancer. But we don't know of any agents for sure that cause cancer in children.

Do other family members need to be screened for it also?

No — except with identical twins, we don't routinely screen family members for non-hereditary forms of cancer. Often, however, siblings need help for psychosocial effects of having someone in the family diagnosed with cancer.

How often do we need to come in to the doctor's office or to the hospital?

Your treatment schedule will depend on the type of cancer, and on the treatment plan. Once the protocol is determined, then your doctor will tell you what is planned, although it’s important to be ready for unplanned variations. Initially, it is likely you will be scheduled to come in multiple times each week, then over time, once a week. Once treatment is finished, your child will need to be followed periodically, again, depending on the type of cancer, the chemotherapy regimen, and your child’s side effects from treatment.

When will my child lose his or her hair?

Most children lose their hair temporarily within the first month of chemotherapy. Very rarely, despite effective treatment for cancer, a child’s hair does not fall out. (It is nothing to worry about, and parents should not be alarmed.) Hair will grow back in when chemotherapy becomes less intensive or is discontinued. It may come in a different color or texture than it was prior to chemotherapy.
