Cancer is a condition in which cells in the body grow uncontrollably and spread to other parts. If detected on time, cancer can be completely cured today. The main causes that increase the risk of cancer are:
Tobacco and alcohol use: Tobacco is the leading cause of cancer deaths worldwide. Smoking causes lung cancer, and chewing tobacco causes cancer of the mouth and throat. Excessive alcohol consumption also increases the risk of liver and breast cancer.
Unhealthy diet and obesity: Excessive consumption of processed meat, foods with artificial colors, and junk food leads to digestive cancers. Excessive weight gain causes hormonal changes and leads to various types of cancers.
Environmental factors and radiation: Excessive sunlight (UV rays) can cause skin cancer. In addition, exposure to toxic fumes, asbestos, and radiation in the workplace can also cause changes in the genetic makeup of cells.
Genetics: About 5% to 10% of cancers are inherited. Changes in certain genes passed from parents to children increase the risk of breast cancer and ovarian cancer.
Infections: Some viruses and bacteria can cause cancer. For example, human papillomavirus (HPV) can cause cervical cancer, and hepatitis B and C viruses can cause liver cancer.
