What is lung cancer?

Lung cancer is the disease when cells in one or both of the lungs undergo abnormal changes and grow out of control. These abnormal cells cannot perform their regular function and reduce the lung’s ability to deliver oxygen to the blood. Tumors may also form as a result of the abnormal growth. In addition, similar to other cancers, lung cancer can spread to other parts of the body as the disease processes. According to 2008 statistics by the American Cancer Society, lung cancer is the second most prevalent cancer type in men and women (after prostate cancer and breast cancer, respectively), and it is the number one killer among all the cancer types.  

What causes lung cancer?

Cigarette smoking is found to be responsible for the majority of lung cancer cases. Similar to other cancer types, lung cancer takes time to develop. Therefore, although lung cancer is often diagnosed among older people, the cause of the disease usually originates from a much younger age. For this reason, young people who smoke may not immediately

Overview

The term “cancer” describes a group of diseases in which cells in a part of the body grow out of control. Cancer can originate from anywhere in the body and can spread to other parts of the body. Some cancers form a solid tumor but others, like cancer of the blood, do not. Cancer affects people of all ages, including children and youth. Although cancer among children and teens is rare, cancer remains the leading cause of death from disease in children under 15. Most cancers that occur in children are caused by changes in the genetic component within the body cell during early childhood.  You cannot “catch” cancer nor give it to someone else. Unlike many other diseases, there is no known way to prevent childhood cancer.  

Leading Cancer Types in Children and Youth

• Leukemia – Leukemia is the most common cancer type for this age group. It describes a group of cancers of the blood or bone marrow, caused by abnormal production of blood cells.
• Brain and nervou

WHAT IS LEUKEMIA?

Leukemia is a cancer of the bone marrow and blood cells where an abnormally large amount of white blood cells are produced.  It is the most common cancer among children and adolescents, accounting for 1 out of 3 cancer cases.  

HOW DOES LEUKEMIA DEVELOP?

When healthy, the bone marrow makes three types of blood cells:

• Red Blood Cells – carry oxygen to all parts of the body
• White Blood Cells – help fight off infections
• Platelets – helps the blood clot when there is an open wound

The bone marrow of persons with leukemia makes many immature white blood cells called blasts. When a large number of blasts are produced, they crowd out the bone marrow from producing normal blood cells. This can lead to anemia, infection and easy bleeding.  

CAN LEUKEMIA BE PREVENTED?

Currently, there are no known ways to prevent childhood leukemia. Leukemia is NOT linked to lifestyle risk factors such as diet and exercise  

COMMON TYPES TYPE OF LEUKEMIA IN CHILDREN AND YOUNG ADULTS

There are several types of leukemia, depending on how rapidly it develops and which type of white blood cell is affected. Acute leukemia progresses rapidly if untreated, while chronic leukemia is very sl
