▶️ Environmental factors are the causes of cancer speech?

Radiation is energy in the form of high-speed particles or electromagnetic waves. Exposure to ultraviolet radiation and ionizing radiation can clearly cause cancer. Exposure to solar ultraviolet radiation is the major cause of non-melanoma skin cancers, which are by far the most common malignancies in human populations.

Environmental factors such as; stress, social status, smoking and obesity can also accelerate telomere shortening due to reduced telomerase activity. In contrast to normal somatic cells, most human tumors have activated telomerase to achieve immortal growth.

These environmental factors include lifestyle choices like cigarette smoking, excessive alcohol consumption, poor diet, lack of exercise, excessive sunlight exposure, and sexual behavior that increases exposure to

Cancer is caused by changes to certain genes that alter the way our cells function. Some of these genetic changes occur naturally when DNA is replicated during the process of cell division.

high incidence of breast cancer, environmental factors have been targeted as a possible cause for this increase.

What causes cancer? There is no one cause for cancer. Scientists believe that it is the interaction of many factors together that leads to cancer. The factors involved may be genetic or environmental. Diagnosis, treatment, and prognosis for childhood cancers are different than for adult cancers. The main differences are the survival rate and the cause of the cancer.

A sporadic (occurs by chance) cell change or mutation is usually what causes childhood cancer. In adults, the type of cell that becomes cancerous is usually an epithelial cell. Epithelial cells line the body cavity and cover the body surface. Cancer occurs from environmental exposures to these cells over time.

One of the main environmental causes of cancer is ultraviolet (UV) radiation from the sun. We know that many skin cancers, including melanoma, are caused by spending too much time in the sun. The people most at risk are those who work outside, and those who are fair-skinned. There are things you can do to reduce your risk (see above).

Cancer is a complex group of diseases with many possible causes. In this section you can learn more about the known causes of cancer, including genetic factors; lifestyle factors such as tobacco use, diet, and physical activity; certain types of infections; and environmental exposures to different types of chemicals and radiation.

If cancer genetic how do environmental factors influence?

The assumption is that the environment is affecting monozygotic and dizygotic twins similarly. Some of these different effects will then be 100 percent, or 1. The nonshared random environmental effect was the largest factor for all cancers, accounting for 58 to 82 percent of the total variation (Lichtenstein et al., 2000). Statistically significant heritability estimates were detected for cancers of the colorectum (35 percent), breast (27 percent), and prostate (42 percent).
