What is Cancer?

Cancer is a broad term used to describe a group of diseases characterized by the uncontrolled growth and spread of abnormal cells in the body. These cells have the ability to invade and damage nearby tissues and organs, and they can also spread to other parts of the body through the bloodstream or lymphatic system, forming secondary tumors in a process called metastasis.

Cancer can affect various parts of the body and can have different signs and symptoms depending on the type and stage of the disease. There are over 200 types of cancer, including breast cancer, lung cancer, prostate cancer, colorectal cancer, and leukemia, among others.

Regarding the number of people who die from cancer each year, it is important to note that the statistics can vary depending on the country, region, and year. The World Health Organization (WHO) estimates that cancer is responsible for approximately 9.6 million deaths worldwide annually. However, it is crucial to consult up-to-date sources and national cancer registries for specific figures as they can change over time due to advances in treatment, prevention efforts, and population demographic.
