What Causes Cancer?
July 13, 2023 | by Yashaswi Pathakamuri | Posted in FAQ's
Cancer is a complex disease that can be caused by a combination of factors. While the exact causes of many types of cancer are still not fully understood, several known factors can increase the risk of developing cancer. Here are some key factors:
- Genetic factors: Certain inherited gene mutations can increase the likelihood of developing cancer. These mutations can be passed down from parents to children and are responsible for a small percentage of cancers.
- Environmental factors: Exposure to various environmental factors can contribute to the development of cancer. This includes exposure to carcinogens such as tobacco smoke, certain chemicals, radiation (e.g., UV radiation from the sun), and certain viruses or bacteria.
- Lifestyle choices: Certain lifestyle choices can increase the risk of developing cancer. These include tobacco and alcohol use, an unhealthy diet (high in processed foods, red meat, or low in fruits and vegetables), lack of physical activity, and being overweight or obese.
- Age: The risk of cancer generally increases with age. As people get older, the cells in their bodies may accumulate genetic mutations that can lead to cancer.
- Chronic inflammation: Long-term inflammation caused by conditions such as inflammatory bowel disease, chronic infections, or prolonged exposure to irritants can increase the risk of cancer in affected tissues.
- Hormonal factors: Some cancers, such as breast and prostate cancer, are influenced by hormones. Hormonal imbalances or prolonged exposure to certain hormones can contribute to the development of these cancers.
It’s important to note that having one or more risk factors does not necessarily mean that a person will develop cancer. Many individuals with one or more risk factors never develop the disease, while others without apparent risk factors can still develop cancer. Cancer is a complex interplay of various factors, and research is ongoing to better understand its causes and develop preventive strategies.
