Childhood cancers

The cancers you see in children are actually somewhat different than we used to seeing in adults. In adults you are probably used to hearing about breast cancer, and lung cancer, or colon cancer, or things like this. In children we see different kinds of cancer. Leukemia and brain tumors are two most common types of cancer we see in children. Actually, account to just about 50% of all the childhood cancer. The rest of the tumors we see are a group of solid tumors, many of which develop in embryonic tissues. That means in the tissues that forms the fetus something goes wrong, and they eventuate in a cancer. That doesn't mean they were inherited. But, something goes wrong during the develop of the fetus. So, we see things like sarcomas, we also see lymphomas. And, we see unusual liver tumors that we don't see in adults. We see kidney cancers that's different than the kidney cancer we see in adults. So, a group of these solid tumors that make up the remaining of the 50%.
