Genetic Mutations: Changes in the DNA that control the function of our cells lead to cancer. These can often be inherited or caused by external factors during life.
Smoking and alcohol: Smoking is the main cause of lung cancer. Alcohol increases the risk of cancer in the mouth, throat, liver, and breast.
Dietary habits: Regular consumption of overly processed foods, foods with artificial colors/flavors, and fried foods is associated with the risk of cancer.
Infections: Some viruses and bacteria can cause cancer. For example:
HPV (Human Papillomavirus) – cervical cancer.
Hepatitis B and C – liver cancer.
H. pylori bacteria – stomach cancer.
Environmental Factors: Air pollution, excessive sun exposure (skin cancer), radiation, and exposure to certain chemicals (asbestos, benzene) are dangerous.
Obesity: Obesity causes chronic inflammation in the body, which leads to various cancers.
Age and immunity: As we age, the risk of DNA damage in cells increases. Also, when the body’s immune system weakens, its ability to destroy cancer cells decreases.
