Genes and genetic cancers: What to know
From the Medical News Today website
In cancer, cells grow and divide at an abnormally fast rate. Cancer may develop because of alterations to the cell’s genes. These changes may be hereditary or caused by environmental factors.
Usually, the body sends signals to tell cells when to stop dividing or die. If there are genetic changes to cells’ behavior, they ignore these signals and continue to reproduce. These cells may spread into the surrounding tissue and may cause tumors.
According to the American Cancer Society, cancer affects one-third of all people in the United States.
