According to the World Health Organization (WHO), cancer is now the second leading cause of death in the world. In 2012, there were about 14 million new cancer cases and 8.2 million cancer deaths. In the next two decades, the number of new cancer cases is expected to increase by about 70%. So, what are the causes for this alarming increase in cancer cases?
The most common causes of cancer are tobacco use, diet and nutrition, physical inactivity, and alcohol use. Other causes include exposure to ultraviolet radiation, air pollution, and certain infections.
Tobacco use is the leading cause of cancer deaths worldwide. It causes cancers of the lung, mouth, throat, esophagus, stomach, pancreas, and cervix. It is also a major cause of cancer deaths in developing countries.
Diet and nutrition are also major causes of cancer. Unhealthy diets high in saturated and processed meats, salt, and sugary drinks can increase the risk of developing cancer. A lack of fruits and vegetables in the diet can also increase the risk.
Physical inactivity is also a major risk factor for cancer. People who are inactive are more likely to develop cancers of the colon, breast, and prostate.
Alcohol use is a major risk factor for cancers of the mouth, throat, liver, and breast.
Exposure to ultraviolet radiation from the sun and tanning beds is a major risk factor for skin cancer.
Air pollution, especially from traffic emissions, can increase the risk of developing lung cancer.
Some infections can also increase the risk of cancer. The human papillomavirus (HPV) is the most common cause of cervical cancer. Helicobacter pylori is a bacterium that causes stomach cancer.
While the causes of cancer are many and varied, there are ways to reduce the risk of developing the disease. Quitting tobacco use, eating a healthy diet, being physically active, and drinking alcohol in moderation are all important ways to reduce the risk. Avoiding exposure to ultraviolet radiation and air pollution can also help. And getting vaccinated against HPV can help prevent cervical cancer.
Cancer cases are increasing day by day and this is a matter of concern for everyone.
Cancer cases are increasing day by day and this is a matter of concern for everyone. There are many factors that are responsible for this increase. Here are some of the main causes for cancer cases:
Smoking: Smoking is one of the main causes of cancer. It increases the risk of cancer in the lungs, mouth, throat, and pancreas.
Diet: Unhealthy diet is another major cause of cancer. A diet high in processed foods and unhealthy fats can increase the risk of cancer.
Obesity: Obesity is also a major risk factor for cancer. It increases the risk of cancer in the breasts, uterus, ovaries, pancreas, and prostate.
Alcohol: Drinking too much alcohol can also increase the risk of cancer. It increases the risk of cancer in the mouth, throat, liver, and breast.
Radiation: Exposure to radiation can also increase the risk of cancer. It increases the risk of cancer in the lungs, thyroid, and breasts.
Chemical exposure: Exposure to chemicals like asbestos and benzene can also increase the risk of cancer.
Genetics: Genetics can also play a role in the development of cancer. Some cancers are more common in certain families.
Age: The risk of cancer increases with age. Most cancers occur in people over the age of 50.
There are many other causes for cancer cases, but these are some of the main ones. If we want to reduce the number of cancer cases, we need to address these causes. We need to make healthy changes to our diet, reduce our smoking and alcohol intake, and avoid exposure to radiation and chemicals.
There are many causes for the increasing cancer rates worldwide. Some include exposure to carcinogens, such as tobacco smoke, radiation, and asbestos; a lack of physical activity; obesity; and improper diet. Many cancers can also be attributed to genetics. However, the increasing rates are also due, in part, to the aging population.
