What are 3 types of things can cause damage to DNA resulting in cancer?

DNA Damage Can Be Repaired by Several Mechanisms

What can damage DNA and cause cancer?

If a person has an error in a DNA repair gene, mistakes remain uncorrected. Then, the mistakes become mutations. These mutations may eventually lead to cancer, particularly mutations in tumor suppressor genes or oncogenes. Mutations in DNA repair genes may be inherited or acquired.

What are 3 causes of mutations that could lead to cancer?

All cancer is the result of gene mutations. Mutations may be caused by aging, exposure to chemicals, radiation, hormones or other factors in the body and the environment. Over time, a number of mutations may occur in a single cell, allowing it to divide and grow in a way that becomes a cancer.

What foods help repair DNA?

One food shown to repair DNA is carrots. They are rich in carotenoids, which are powerhouses of antioxidant activity. A study that had participants eating 2.5 cups of carrots per day for three weeks found, at the end, the subjects’ blood showed an increase in DNA repair activity.

What is the relationship between DNA and cancer?

Cancer is out-of-control cell division. It involves a change in the DNA structure that causes an alteration of the normal DNA regulating mechanisms. The malignant (cancerous) cells no longer respond to normal regulatory signals. Cancer most often strikes older individuals.

What can happen if your DNA is altered?

The most significant consequence of oxidative stress in the body is thought to be damage to DNA. DNA may be modified in a variety of ways, which can ultimately lead to mutations and genomic instability. This could result in the development of a variety of cancers including colon, breast, and prostate.

Can DNA repair itself?

Most damage to DNA is repaired by removal of the damaged bases followed by resynthesis of the excised region. Some lesions in DNA, however, can be repaired by direct reversal of the damage, which may be a more efficient way of dealing with specific types of DNA damage that occur frequently.

What is DNA damage give its causes?

DNA damage occurs continuously as a result of various factors—intracellular metabolism, replication, and exposure to genotoxic agents, such as ionizing radiation and chemotherapy. If left unrepaired, this damage could result in changes or mutations within the cell genomic material.

What are the two main defects that lead to cancer?

The current list of known cancer genes includes 70 genes associated with germline mutations and 342 genes associated with somatic mutations. Generally speaking, however, mutations in two basic classes of genes—proto-oncogenes and tumor suppressor genes—are what lead to cancer.

Which of the following is most likely to lead to cancer?

The most common risk factors for cancer include aging, tobacco, sun exposure, radiation exposure, chemicals, and other substances, some viruses and bacteria, certain hormones, family history of cancer, alcohol, poor diet, lack of physical activity, or being overweight.

What things can alter your DNA?

Environmental factors such as food, drugs, or exposure to toxins can cause epigenetic changes by altering the way molecules bind to DNA or changing the structure of proteins that DNA wraps around.

What food causes DNA damage?

It can make its way into your diet through contaminated foods such as dried fruits, bruised apples, and improperly stored cereal grains. It’s also been detected in many milk-based infant formulas, cereal-based baby foods, and apple-based baby foods as well. This article originally appeared on RodaleWellness.com.
