Causes of Cancer
Tobacco Use: Smoking and use of tobacco products, including chewing tobacco, significantly increase the risk of various types of cancer, including lung, throat, mouth, and bladder cancer.
Exposure to UV Radiation: Prolonged exposure to ultraviolet (UV) radiation from the sun or tanning beds can cause skin cancer, including melanoma, basal cell carcinoma, and squamous cell carcinoma.
Dietary Factors: A diet high in processed foods, red meat, and low in fruits and vegetables is associated with an increased risk of cancer. Additionally, excessive alcohol consumption is linked to certain types of cancer, including liver, breast, and esophageal cancer.
Obesity: Being overweight or obese increases the risk of developing several types of cancer, including breast, colon, kidney, and pancreatic cancer.
Environmental Factors: Exposure to environmental pollutants such as asbestos, benzene, and certain pesticides can increase the risk of developing cancer.
Genetic Factors: Inherited genetic mutations can predispose individuals to certain types of cancer, such as breast, ovarian, and colorectal cancer.
Viral Infections: Certain viruses, such as human papillomavirus (HPV), hepatitis B virus (HBV), and hepatitis C virus (HCV), are linked to an increased risk of developing cancer, including cervical, liver, and stomach cancer.
Radiation Exposure: Exposure to ionizing radiation from sources such as medical imaging procedures (X-rays, CT scans) and radiation therapy for cancer treatment can increase the risk of developing cancer.
Hormonal Factors: Hormonal imbalances or prolonged exposure to hormones, such as estrogen and testosterone, can increase the risk of certain types of cancer, including breast and prostate cancer.
Chronic Inflammation: Chronic inflammation caused by conditions such as inflammatory bowel disease (IBD) or chronic infections can increase the risk of cancer in affected tissues.
