Childhood Cancer Awareness Month – what is childhood cancer and how are families supported?

September is childhood cancer awareness month, and many families across Ireland are all too aware of the challenges posed by childhood cancer.

The Irish Cancer has gathered information and resources to help families through this difficult time.

One of the services the organization provides is a peer-to-peer support line where all volunteers are parents who have had children treated for cancer.

The Irish Cancer Society’s website has information to help parents deal with the overwhelming news that their child has cancer. It also contains useful information about what to expect from treatment and how to deal practically and emotionally during and after treatment.

Another major focus of Childhood Cancer Awareness Month is raising awareness of some of the cancers that fall into this category.

So what is childhood cancer?

Cancer is not one condition, but rather it is an umbrella term for more than 200 diseases that cause abnormal or defective cells in the body to grow and multiply.

Although relatively rare in children compared to adults, a cancer diagnosis is devastating for any family.

According to the Irish Cancer Society, about 170 children and teenagers under the age of 15 are affected by childhood cancer in Ireland each year.

Cancer in children usually occurs in different parts of the body to cancer in adults. They also look different under the microscope and respond differently to treatment.

Cure rates for children are much higher than for most adult cancers. On average, more than eight in ten children in Ireland survive cancer for five years or more.
