What is cancer? Causes of cancer, do you know?

Before finding out causes of cancer, below are the concepts of cancer that you may not know!

Cancer is a complex and widespread disease characterized by the uncontrolled growth and division of abnormal cells in the body. These abnormal cells can invade and destroy healthy tissues, impairing the normal functioning of organs. Cancer can occur in various parts of the body and can spread to other areas through the bloodstream or lymphatic system, a process known as metastasis. 

Currently, there are more than 200 types of cancer that have been discovered by scientists.

Causes of Cancer

While the exact causes of cancer is not always clear, several factors are known to contribute to its development. Understanding these causes can help individuals make informed choices to reduce their risk of developing cancer.

1. Genetic Factors: Certain inherited genetic mutations can increase the risk of developing specific types of cancer. These mutations can be passed down from parents to children.

2. Environmental Factors: Exposure to carcinogens (cancer-causing substances) in the environment can significantly increase cancer risk. Examples include:

• Tobacco Smoke: Smoking is a leading cause of several types of cancer, including lung, throat, and bladder cancer.
• Ultraviolet (UV) Radiation: Excessive exposure to sunlight and tanning beds can increase the risk of skin cancer.
• Air Pollution: Prolonged exposure to air pollutants, such as those from vehicle exhaust or industrial emissions, may contribute to lung cancer. 
• Chemical Exposures: Occupational exposure to certain chemicals used in industries like asbestos, benzene, and formaldehyde can increase cancer risk.

3. Lifestyle Choices: Certain lifestyle habits can influence cancer risk:

• Unhealthy Diet: Nutrition plays a role in about 35% of the causes of cancer. Consumption of processed foods high in fats and sugars, as well as low intake of fruits and vegetables, can contribute to cancer development.
• Physical Inactivity: People who are sedentary and lazy often cause the body’s immune system and resistance to decline. This makes the body more susceptible to cancer and other diseases.
• Obesity: Being overweight or obese can increase the risk of developing various types of cancer.

4. Infections: Some infections are linked to an increased risk of cancer. For example:

• Human Papillomavirus (HPV): HPV infection can lead to cervical, anal, and other types of cancer.
• Hepatitis B and C Viruses: Chronic infection with these viruses can increase the risk of liver cancer.

5. Age and Gender: The risk of developing cancer generally increases with age. Certain types of cancer are more common in specific genders, such as prostate cancer in males and breast cancer in females.

Above are causes of cancer and some related information. Hopefully, these will be useful shares to help readers clearly understand and proactively implement measures to minimize the risk of cancer for themselves and their families. If you have concerns about cancer risk factors or symptoms, consult a healthcare professional for personalized guidance and advice.
