Question

Quizplus · Accepted Answer

Cancer is a result of accumulating somatic mutations, which is more likely to occur over time with age. Several mutations are required for cancer to develop, making it a multi-step process. Mutual translocations (B) are a type of chromosomal abnormality that may contribute to the development of some cancers, but it is not the only mechanism. Cancer is a genetic disease (A), but this choice is too broad and not specific enough. Expanding triplet repeats (D) are associated with a few rare genetic disorders but not commonly linked to cancer. Deletions of different lengths (E) are another type of chromosomal abnormality, but, like choice B, it is not the exclusive cause of cancer.
