For example, breast cancer and ovarian cancer run together in families with hereditary breast and ovarian cancer syndrome (HBOC).
Colon and endometrial cancers tend to go together in Lynch syndrome (also known as hereditary non-polyposis colorectal cancer, or HNPCC).
But in some cases the cancer is caused by an abnormal gene that is being passed along from generation to generation.
Although this is often referred to as ) inherited from a parent. Cancer is a disease in which cells grow out of control.
But if the other gene copy stops working (because of an acquired mutation, for example), the gene’s function can be lost altogether.
When the gene that stops working is a tumor suppressor gene, cells can grow out of control, which can lead to cancer.
The genes that the cell doesn’t need are turned off and not used. For example, a mutation might stop a gene from working.
Certain things make it more likely that cancers in a family are caused by a family cancer syndrome, such as: Cancer in a close relative, like a parent or sibling (brother or sister), is more cause for concern than cancer in a more distant relative.
Even if the cancer was from a gene mutation, the chance of it passing on to you gets lower with more distant relatives.
Gene mutations can be either inherited or acquired. These are genes that normally keep cells under control by slowing down how often they divide (to make new cells), repairing DNA mistakes, or telling cells to die at the right time.
You have 2 copies of most genes – one from each parent.
