Question: 1


Which of the following is a characteristic of triple-negative breast cancer?


  1. Expression of estrogen receptor (ER)

  2. Expression of progesterone receptor (PR)

  3. Lack of expression of ER, PR, and HER2


    wer: C


    anation: Triple-negative breast cancer refers to a subtype of breast ca oes not express the estrogen receptor (ER), progesterone receptor (P an epidermal growth factor receptor 2 (HER2). This subtype accounts oximately 10-20% of all breast cancer cases and is often associated wi aggressive disease course and limited treatment options.

Answer: D


Explanation: The HER2-enriched subtype of breast cancer is characterized by the overexpression of the human epidermal growth factor receptor 2 (HER2). It represents approximately 15-20% of all breast cancer cases and is associated with a more aggressive disease course. Targeted therapies, such as trastuzumab

(Herceptin), can effectively treat HER2-positive breast cancer.


Question: 3


Which of the following is a common long-term complication of radiation therapy in breast cancer patients?

    Explanation: Early menopause, defined as menopause occurring before the age

    of 45, is an established risk factor for the development of breast cancer. It is associated with a longer lifetime exposure to estrogen, which can increase the risk of breast cancer.

    Explanation: Tamoxifen is a commonly used hormone therapy medication in the treatment of hormone receptor-positive breast cancer. It acts by blocking the estrogen receptors in breast cancer cells, suppressing their growth and reducing the risk of cancer recurrence.



    ch of the following is a common side effect of chemotherapy in breast er patients?
