Question

Quizplus · Accepted Answer

A family member with multiple cancers is more likely to indicate a genetic link to the disease(s). This is because multiple cancers in a family member suggest inherited mutations or genetic predispositions to cancer. The other options may not necessarily indicate genetic links to a disease, as poor health habits or late onset of a disease can also be attributed to environmental factors or other non-genetic factors. The appearance of a disease in one family member may also be due to chance or non-genetic factors.
