The BBC website reports today that women at risk of breast cancer miss out on tests and early diagnosis because their father’s family’s health history is disregarded, a study has suggested. Canadian researchers say in Lancet Oncology that women were more likely to report a history of the disease on their mother’s side. They found women with a maternal cancer history were five times more likely to be referred by family doctors. A UK cancer charity said a father’s history was “often overlooked”.
It is thought that between 5% and 10% of breast and ovarian cancers are the result of a genetic inheritance. This is equally likely to have come from either the father or mother. A significant chunk of this genetic risk is known to come from defects on either the BRCA1 or BRCA2 genes, which make it much more likely that a woman will develop breast or ovarian cancer in her lifetime. If a woman has a strong family history of breast cancer, she can be referred for further testing to see if she has a known gene defect. She can then take steps to reduce the risk, or simply get checked more regularly to catch the cancer early.
