When identified early, cancer is more likely to respond to treatment and can result in a greater chance of survival. However, it is important to identify and treat cancer as early as possible. (Al Jazeera) How many people die from cancer? Among women, breast cancer is the most common, accounting for about one-quarter (25.8 percent) of the total new cases in 2020. Lung cancer is the most common type of cancer among men, contributing 15.4 percent of all new cancer diagnoses in 2020. The two most common types of cancer worldwide are breast and lung cancer, contributing 12.5 percent and 12.2 percent, respectively of the total number of new cancer diagnoses in 2020, according to the World Health Organization (WHO). The types of cancer are usually named after the organs or tissues where they originate. (Al Jazeera) The most common types of cancerĪccording to the US-based National Cancer Institute, there are more than 100 different types of cancer.Ĭancer can start almost anywhere in the body, including bones, organs and skin. This stage is often referred to as advanced cancer. Stage 4 (distant spread): Cancer cells have spread beyond nearby tissues and into lymph nodes and parts of the body, including organs, potentially far from the original site. Stage 3 (regional spread): Cancer has grown more deeply into neighbouring tissues and spread to lymph nodes but has not spread to distant sites in the body. Stage 2 (localised): Tumour cells have spread deeper into neighbouring tissues, but not to distant sites in the body. Stage 1 (early-stage): Cancer has not infiltrated deeply into nearby tissues, nor has it spread to lymph nodes or locations away from the primary tumour. Stage 0: Abnormal cells are present but have not spread to nearby tissues. The development of cancer is measured in stages and is determined by a few different factors, including the size and location of the tumour: These cells can then invade nearby tissues and spread to other parts of the body. A normal cell first grows, then divides and finally dies.Ĭancer cells, on the other hand, undergo genetic changes leading them to divide uncontrollably. Every day, new cells grow and multiply in a process called cell division. The human body consists of trillions of cells. In the following infographic series, Al Jazeera takes a look at one of the world’s largest health problems. Of these, 9.3 million cases were in men and 8.8 million in women. In 2020, more than 18 million people were diagnosed with a form of cancer.
