Some families appear to be more susceptible to brain cancer than others. Research shows that in a tiny percentage of cases, it can pass down through generations. However, hereditary brain cancer only occurs in 10 percent of diagnoses so the risk is low. Nonetheless, it’s wise to be aware of family history.
According to Healthline, brain tumors are the second most common form of cancer in children. Prospective parents with a history of brain cancer in their families should be aware of this. While it’s unlikely that they’ll experience it, it’s not impossible and it’s wise to be prepared.
