A typical personal entry

Family History Section

Family History Section There are five box types – – – – – ‘Number’ edit boxes ‘Age’ edit boxes ‘Affected status’ check boxes ‘Ovarian status’ check boxes ‘Bilateral’ check boxes

Number boxes Number boxes are used to enter the number of relatives – After increasing a number box’s value some of the other boxes will be activated. This is because now there are more relatives for which data is needed – Conversely after decreasing a number box’s value some of the other boxes will be deactivated.

Age boxes Age boxes are used to enter relative’s ages. If the age isn’t known then you should enter ‘?’. The age will be estimated based on the person’s age and relationship to the relative. If nothing is known about the relative then you should enter ‘u’. This represents missing data about the relative.

Check boxes The ‘Affected status’ check box determines whether a relative has had breast cancer – If it is unchecked then the corresponding bilateral check box is also unchecked. The ‘Bilateral’ check box determines whether a relative has had bilateral breast cancer – If it is checked then the corresponding affected status check box is also checked. The ‘Ovarian’ check box determine whether a relative has had ovarian cancer. – If it is checked then a dialog comes up asking for the age at ovarian cancer.
