If you want to know more about the different types of cancer and the parts of the body where they can cause death, then AmericanPost.News shares all the details in the framework of World Cancer Day 2022.
What is the cause of death from Cancer?
The leading cause of cancer death, according to the WHO, is that abnormal cells multiply “beyond their usual limits” so they can invade adjacent parts of the body or spread to other organs. This process is called “metastasis.”
In the Americas, cancer is the second leading cause of death. It is estimated that by 2020 four million people were diagnosed with this disease and 1.4 million died from it.
PAHO said in 2021 that 47% of deaths occur in people 69 years of age or younger. By 2040 cases are projected to rise to about 30 million new cases. The 2018 estimate was that by 2024 cancer cases will rise to more than 4 million new cases and 1.9 million deaths.
Cancer develops due to various alterations that may include the interaction of genetic factors and external agents, such as: alcohol consumption, overweight and obesity, poor diet, lack of physical activity, tobacco use, ultraviolet and ionizing radiation, among others.
Genetics, age, and those with a weak immune system are also prone to developing cancer, according to the World Cancer Day 2022 page.
