Cancer is a complex group of diseases characterized by the uncontrolled growth and spread of abnormal cells. It starts when certain cells in the body begin to divide and grow without the normal regulatory signals that control cell growth. This can be due to a variety of factors, including genetic mutations, environmental exposures, and lifestyle choices.
Causes of Cancer:
1. Gene mutations: These can be inherited (present from birth) or acquired after birth. Acquired mutations are the most common and can be caused by various factors.
2. External factors: Such as smoking, exposure to radiation, certain viruses (like human papillomavirus or HPV), and carcinogens (cancer-causing substances found in tobacco smoke, asbestos, and some chemicals).
3. Lifestyle factors: Obesity, a diet high in red meat and low in fruits and vegetables, lack of physical activity, and excessive alcohol consumption are all linked to an increased risk of developing certain types of cancer.
4. Chronic inflammation: This can lead to DNA damage and an increased risk of cancer.
5. Hormones: Hormonal imbalances or exposure to certain hormones, particularly over long periods, can increase the risk of hormone-related cancers.

Gene mutations that occur after birth. Most gene mutations occur after you're born and aren't inherited. A number of forces can cause gene mutations, such as smoking, radiation, viruses, cancer-causing chemicals (carcinogens), obesity, hormones, chronic inflammation and a lack of exercise.
