This booklet was written for children who have a parent or sibling with cancer. It is intended to help readers understand more about cancer, how it is treated, and changes that may be happening in the family's life because of cancer. In addition, it is intended to help readers understand and deal with their feelings about cancer and about the person in the family who has cancer. Sections discuss cancer in the family, whether cancer can be cured, and learning more about cancer. A section on cancer treatment explains surgery, chemotherapy, radiation therapy, and side effects of treatment. Reading and learning more about cancer are discussed. A section on cancer in the family considers the difficulty in talking about cancer; feeling scared, guilty, mad, neglected, lonely, and embarrassed; answering questions; dealing with side effects; and changing. Other sections describe how parents may feel; putting it all together; and other sources of cancer information, including a toll-free telephone line to answer questions and other booklets. Sidebars throughout the text focus on: (1) some things you should know; (2) words used when talking about cancer; (3) words used in talking about cancer treatment; (4) doctors who work with cancer patients; (5) people besides your parents you can talk to; and (6) remember.
