Why counting matters
One relative with a common late cancer is bad luck. Several relatives, or any diagnosis before fifty, shifts the probability toward inherited mutations that change screening age and intensity.
Understanding your result
- Zero to one matches average population risk
- Two to three elevates the pattern
- Three or more is the threshold where genetic counseling pays off
Which patterns shout
The same cancer repeating across generations, related cancers like breast and ovarian, male breast cancer, and any childhood cancer all strengthen the signal beyond the raw count.
What counseling gives you
A counselor maps three generations, estimates mutation probability and may recommend testing that personalizes your screening schedule for decades.
