Question

Quizplus · Accepted Answer

Certain types of cancer often share the same chromosomal abnormalities. This suggests that these abnormalities are a result of genetic mutations that contribute to the development of cancer. Additionally, research has shown that mutations in certain genes, such as tumor suppressor genes and oncogenes, can lead to the development of cancer. These genetic mutations can be inherited or acquired over time through exposure to environmental factors such as tobacco smoke and radiation. Thus, cancer is largely considered to be a genetic disease.
