What internal factors cause cancer?
What internal factors cause cancer?
Internal Factors Some factors that cause cancer are related to systems inside the body. For example, abnormal hormone levels in the bloodstream can cause cancer. A weakened immune system can also lead to cancer. Hereditary factors can also increase the risk of developing cancer.
Is cancer internal or external?
In summary, cancer is caused by both external (chemical, radiation, and viruses) and internal (hormones, immune conditions, and inherited mutations) factors. Causal factors may act together, or in sequence, to initiate or promote carcinogenesis.
What are three internal risks for increased cancer?
General risk factors for cancer include:
- Older age.
- A personal or family history of cancer.
- Using tobacco.
- Obesity.
- Alcohol.
- Some types of viral infections, such as human papillomavirus (HPV)
- Specific chemicals.
- Exposure to radiation, including ultraviolet radiation from the sun.
Are there any external or internal risk factors for cancer?
With further scientific research, more cancer risk factors will be identified in the future. In summary, cancer is caused by both external (chemical, radiation, and viruses) and internal (hormones, immune conditions, and inherited mutations) factors.
When is a risk factor linked to cancer?
When many studies all point to a similar association between a potential risk factor and an increased risk of cancer, and when a possible mechanism exists that could explain how the risk factor could actually cause cancer, scientists can be more confident about the relationship between the two.
Are there any environmental factors that cause cancer?
These are just a few exposures in the environment that may cause cancer. Any substance that causes cancer is known to be a carcinogen. If allowed to accumulate in the body for extended period of time, there is a greater likelihood your cells will become damaged, which results in the growth of cancer cells.
Which is a risk factor for skin cancer?
Different cancers have different risk factors. For example, exposing skin to strong sunlight is a risk factor for skin cancer. Smoking is a risk factor for many cancers. But having a risk factor, or even several, does not mean that you will get the disease. 1

What are some environmental factors that can cause cancer?
Environmental Exposures. Exposure to asbestos, a group of minerals found in housing and industrial building materials can cause a variety of medical problems, such as mesothelioma – a cancer of the lung lining . Studies have shown that people who are exposed to high amount of benzene are at risk for cancer.
