Lung cancer is a condition where certain cells in the lungs behave abnormally, multiply uncontrollably, and start forming a tumor. Worldwide, lung cancer is the leading cause of cancer deaths. Although the cancer originated in the lungs, it may spread to the person’s lymph nodes and other organs, such as the brain.
Is lung cancer genetic?
After learning that an immediate family member or a relative has developed lung cancer, you must be wondering if you, too, are at risk. According to experts, the risk increases when the person’s parents, siblings, or children also have lung cancer.
However, they noted that this could be the case because family members often live or work together and are exposed to the same substances that trigger cancer, such as cigarette smoke.
But, outside those factors, do the genes we inherit from our parents also increase our lung cancer risk?
Most cases of lung cancer are not related to inherited gene changes…
Numerous studies revealed that genetic factors contribute to lung cancer development. However, most cases are not associated with inherited gene changes.
It means that, in most cases, people inherit normal genes in their cells; but these genes change or mutate after exposure to some lung cancer risk factors.
