Cancer is a group of diseases characterized by abnormal and uncontrolled cell growth that can affect any tissue or organ in the body, making them outgrow their usual boundaries to invade adjoining parts of the body and/or spread to distant organs.The latter process is called metastasis and is a major cause of death from cancer.
According to WHO, Cancer is the second leading cause of death globally behind cardiovascular diseases. It accounts for an estimated 9.6 million deaths, or 1 in 6 deaths, in 2018. Lung, prostate, colorectal, stomach and liver cancer are the most common types of cancer in men, while breast, colorectal, lung, cervical and thyroid cancer are the most common among women in that order.
300 000 new cases of cancers are diagnosed each year among children aged 0-19 years.
Approximately 70% of deaths from cancer occur in low- and middle-income countries.
The total annual economic cost of cancer in 2010 was estimated at approximately US$ 1.16 trillion.
