No one in Rohan's immediate family has cancer. What does this MOST likely mean?

Question

He will never get cancer.
His mom does not have cancer-causing genes.
His dad does not have cancer-causing genes.
He could possibly get cancer.

Answer 1

It means that there is no history of cancer in Rohan's immediate family. However, this does not guarantee that Rohan will never get cancer. While the absence of cancer in his immediate family reduces his risk, other factors such as lifestyle choices, genetic mutations, and environmental factors can still contribute to the development of cancer.
