Breast Disorders: Fibrocystic Breast Changes, Breast Cancer
Breast Disorders: Fibrocystic Breast Changes, Breast Cancer ( 15 Questions)
Which statement accurately describes a key aspect of breast cancer's pathophysiology?
"Breast cancer is characterized by hormonal fluctuations." This statement is not accurate in describing breast cancer's pathophysiology. While hormones like estrogen and progesterone can influence the development and growth of some breast cancers, breast cancer itself is not characterized by hormonal fluctuations. Hormonal factors are just one of the many contributing factors to breast cancer.
"Accumulation of abnormal cells leads to the formation of a tumor." This is the correct choice. Breast cancer is a disease characterized by the uncontrolled growth and accumulation of abnormal cells within the breast tissue. Over time, these abnormal cells can form a tumor, which may be benign (non-cancerous) or malignant (cancerous).
"Breast cancer primarily affects the lungs, liver, and brain." This statement is inaccurate. Breast cancer primarily originates in the breast tissue itself and may spread (metastasize) to other organs or tissues, such as the lungs, liver, and brain, in advanced stages. However, the primary site of breast cancer is the breast tissue, not these other organs.
"Genetic mutations have no role in breast cancer development." This statement is incorrect. Genetic mutations can play a significant role in the development of breast cancer. Some individuals may inherit mutations in specific genes like BRCA1 and BRCA2, which increase their risk of developing breast cancer. Additionally, acquired mutations in breast cells can also contribute to the development of the disease.
Choice A rationale:
"Breast cancer is characterized by hormonal fluctuations." This statement is not accurate in describing breast cancer's pathophysiology.
While hormones like estrogen and progesterone can influence the development and growth of some breast cancers, breast cancer itself is not characterized by hormonal fluctuations.
Hormonal factors are just one of the many contributing factors to breast cancer.
Choice B rationale:
"Accumulation of abnormal cells leads to the formation of a tumor." This is the correct choice.
Breast cancer is a disease characterized by the uncontrolled growth and accumulation of abnormal cells within the breast tissue.
Over time, these abnormal cells can form a tumor, which may be benign (non-cancerous) or malignant (cancerous).
Choice C rationale:
"Breast cancer primarily affects the lungs, liver, and brain." This statement is inaccurate.
Breast cancer primarily originates in the breast tissue itself and may spread (metastasize) to other organs or tissues, such as the lungs, liver, and brain, in advanced stages.
However, the primary site of breast cancer is the breast tissue, not these other organs.
Choice D rationale:
"Genetic mutations have no role in breast cancer development." This statement is incorrect.
Genetic mutations can play a significant role in the development of breast cancer.
Some individuals may inherit mutations in specific genes like BRCA1 and BRCA2, which increase their risk of developing breast cancer.
Additionally, acquired mutations in breast cells can also contribute to the development of the disease.
