Final answer:
Cancer can have multiple potential causes including genetics, environmental factors, lifestyle choices, infections, and radiation.
Step-by-step explanation:
There are several potential causes of cancer:
- Genetics: Certain gene mutations can increase the risk of developing cancer, such as the BRCA genes for breast cancer.
- Environmental factors: Exposure to carcinogens like tobacco smoke, asbestos, and UV radiation can trigger cancer development.
- Lifestyle choices: Poor diet, lack of physical activity, and excessive alcohol consumption can contribute to cancer.
- Infections: Viruses like HPV, hepatitis B and C, and human immunodeficiency virus (HIV) can increase the risk of certain cancers.
- Radiation: High doses of ionizing radiation, such as from radiation therapy or nuclear accidents, can lead to cancer.
