True, an individual's health is affected by their environment and personal genetic makeup.
Environment: For example, if someone lives in an air-polluted environment, their lungs will most likely suffer from irritation, infections, and other related sicknesses/diseases. Long-term, it may possibly lead to lung cancer.
Genetic makeup: This is something that cannot be prevented. For example, if someone's family has a extended history of brain cancer, the chances of the individual getting brain cancer is much higher than someone who does not have a history of brain cancer in their family.
