On the occasion of World No Tobacco Day, observed on May 31 by the World Health Organization, leading health experts in Saudi Arabia urged people to take action and curb the harmful effects of tobacco consumption and smoking.Tobacco smoking can affect almost every part of the body, leading to heart and lung diseases, among others. It is one of the most common causes of lung cancer. "People who smoke cigarettes are 15 to 30 times more likely to get lung cancer or die from lung cancer than people who do not smoke. Even smoking a few cigarettes a day or smoking occasionally increases the risk of lung cancer. More the number of years a person smokes and the more cigarettes smoked each day, higher is the risk. Quitting smoking at an early age can lower the risk of lung cancer." expressed Dr. Turki Al Fayae, King Abdulaziz Medical City, Princess Noorah Oncology Center, Jeddah. Tobacco smoke contains more than 4000 chemicals, such as benzene, cyanide and carbon monoxide. A number of these chemicals are called "carcinogenic" – which means that they can cause cancer. A shisha is NOT a safer alternative: In general, most people know that cigarettes are bad for health. But many do not realize that even water pipe smoking or shisha) may be just as harmful for health as cigarette smoking. Is second-hand smoking also bad? - No one is safe from the harmful effects of tobacco smoking. According to WHO, about 600 000 people die every year because of being exposed to "second-hand smoke" – which is the kind of smoke one is exposed to if someone else in the home or office smokes. This is linked to lung cancer. "People need to realize that the best way to combat lung cancer is by preventing the disease. Awareness of the disease, its symptoms and early diagnosis is crucial. In the last few years, medical sciences have advanced in the treatment of lung cancer. Timely detection plays a significant role in ensuring that the disease is treated at an early stage, increasing the chances of survival. In fact, some recent studies have reflected positive outcomes in people with advanced non-small cell lung cancer (NSCLC) using latest therapies such as immuno-therapies." said Dr. Abdulrahman Jazieh, Chairman, Department of Oncology at King Abdulaziz Medical City – National Guard Hospital.

The goal is to address the unmet need for long-term survival in patients with advanced cancers. The immune system is a network of organs, cells, and molecules throughout the whole body. The role of the immune system is to protect the body from harmful things like germs, viruses, and diseases like cancer. Immune responses are the way the body works to find and destroy abnormal cells, including cancer cells. Immunotherapy is the use of medicines to stimulate a person's own immune system to recognize and destroy cancer cells more effectively. It can be used to treat some forms of non-small cell lung cancer. New treatment options have become available and are helping to improve outcomes and survival for patients. Based on the diagnosis, oncologists undertake suitable treatment paths like surgery, radiotherapy, chemotherapy and medication. Lung cancer is the most common cancer worldwide, accounting for 1.61 million new cases annually representing 12.7% of all new cancers By 2020, there are expected to be 14,788 new lung cancer cases in the Arab countries for ages below 65, and 14,788 cases for ages above 65 in both males and females. There are more than 4000 chemicals in tobacco smoke, of which at least 250 are known to be harmful and more than 50 are known to cause cancer. Lung cancer is the 5th most common cancer amongst Saudi males.
