In simple words that even a third grader can understand:
Genes are short pieces of DNA that makes protiens that tells your body what traits make you. You get your genes from your PARENTS! As an example if your mom and dad have brown eyes, you're most likely to get brown eyes. They do this by the genes producing protiens that tell your cells what to produce such aas curly hair. Protiens would tell the hair cells to curl your hair from genetics.
When genes make a nonfunctional protiens it turns into a cancer. The build up of cancer is a tumor. Cancer can be geneticlly inherited. White blood cells do try to fight the cancerous cells because the mutated cell is not part of your body but since caner cells divide so quickly they can't get them all.
