Is breast cancer a multifactorial disorder?

Breast cancer is a complex, multifactorial disease where there is a strong interplay between genetic and environmental factors. At present, approximately 180 000 women are diagnosed with breast cancer each year in the United States (1).

Is cancer a multifactorial disease?

Cancers are chronic multifactorial diseases whose genesis occurs at a variable rate.

What type of genetic disorder is breast cancer?

BRCA1 and BRCA2: The most common cause of hereditary breast cancer is an inherited mutation in the BRCA1 or BRCA2 gene. In normal cells, these genes help make proteins that repair damaged DNA. Mutated versions of these genes can lead to abnormal cell growth, which can lead to cancer.

What are multifactorial disorders?

Multifactorial diseases are caused by a combination of the effects of multiple genes or by interactions between genes and the environment.

Does your breast hurt with cancer?

Breast cancer can cause changes in skin cells that lead to feelings of pain, tenderness, and discomfort in the breast. Although breast cancer is often painless, it is important not to ignore any signs or symptoms that could be due to breast cancer. Some people may describe the pain as a burning sensation.

What are the odds of surviving breast cancer?

The overall 5-year relative survival rate for breast cancer is 90%. This means 90 out of 100 women are alive 5 years after they’ve been diagnosed with breast cancer. The 10-year breast cancer relative survival rate is 84% (84 out of 100 women are alive after 10 years).

Why do you think cancer is a multifactorial disease?

Cancer may therefore be considered a multifactorial disease, resulting from the combined influence of many genetic factors acting in concert with environmental insults (e.g., ultraviolet radiation, cigarette smoke, and viruses).

Are all disease genetic?

Researchers are learning that nearly all conditions and diseases have a genetic component. Some disorders, such as sickle cell disease and cystic fibrosis, are caused by variants (also known as mutations) in single genes. The causes of many other disorders, however, are much more complex.

Is cancer hereditary from parents or grandparents?

Although cancer is common, only 5-10% of it is hereditary, meaning an individual has inherited an increased risk for cancer from one of their parents. This inherited risk for cancer is caused by a small change (called a mutation) in a gene, which can be passed from one generation to the next in a family.

What happens if you test positive for BRCA?

A positive test result means that you have a mutation in one of the breast cancer genes, BRCA1 or BRCA2, and therefore a much higher risk of developing breast cancer or ovarian cancer compared with someone who doesn’t have the mutation. But a positive result doesn’t mean you’re certain to develop cancer.
