Cancer is a disease in which cells grow and proliferate to produce progeny that are . Therefore, we consider it a __ disease. a) cancerous, cancerous, cellular b) cancerous, cancerous, genetic c) normal, normal, inflammatory d) none of these
The correct answer and explanation is:
The correct answer is b) cancerous, cancerous, genetic.
Cancer is a disease characterized by the uncontrolled growth and proliferation of abnormal cells in the body. These cells are referred to as cancerous cells because they have acquired mutations that disrupt normal cell function, allowing them to grow uncontrollably. As cancer cells divide, they produce cancerous progeny, meaning the new cells also carry the same mutations and abnormal behavior as the parent cells. This uncontrolled growth is a hallmark of cancer.
Cancer is considered a genetic disease because it results from genetic changes or mutations in the DNA of cells. These mutations can be inherited or acquired over time due to environmental factors like exposure to toxins, radiation, or viruses, or due to random errors during DNA replication. The mutations in the cancerous cells disrupt normal cell regulation mechanisms, including those that control cell division, cell death, and repair of damaged DNA. This genetic alteration is what leads to the formation and expansion of tumors.
Unlike other diseases that might involve normal cells or inflammation, cancer’s core issue is the genetic alteration of cells that allows them to bypass the normal growth controls in the body. The accumulation of genetic mutations over time causes these cells to continue dividing and forming a mass of cancerous tissue, which can invade surrounding tissues and spread to other parts of the body.
In summary, cancer is a genetic disease because it involves genetic changes in the DNA of cells, causing them to grow and proliferate abnormally. The correct answer is therefore option b).
