Final answer:
A genetic counselor would inform the 60-year-old female with the mutated kid gene that she may still develop cancer later in life, although it is not guaranteed. Regular screenings for early detection and treatment would be emphasized.
Step-by-step explanation:
A genetic counselor would explain to the 60-year-old female that although she has not developed the disease yet, she still may develop cancer later in life because she carries the mutated form of the gene known as the kid gene. The counselor would inform her that while the presence of the mutated gene increases the risk of developing cancer, it does not guarantee that she will develop the disease. The counselor would also emphasize the importance of regular screenings for early detection and treatment if cancer does develop.
