1.
Breast cancer accounts for ____% of malignancies in men.
Correct Answer
A. Less than 1
Explanation
Breast cancer is a rare occurrence in men, accounting for less than 1% of all malignancies. While breast cancer is commonly associated with women, men can also develop the disease, although at a much lower rate. Therefore, it is accurate to say that breast cancer accounts for less than 1% of malignancies in men.
2.
Which anatomical structures typically develop in the male breast?
Correct Answer
A. Ductal structures
Explanation
The male breast typically develops ductal structures. These structures are responsible for transporting milk from the lobules to the nipple. While complex lobular structures and terminal ductal lobular units are found in the female breast, they are not typically present in the male breast. Similarly, lobular units and acini are also more commonly found in the female breast. Therefore, the correct answer is ductal structures.
3.
A common temporary benign enlargement of the male breast is ____.
Correct Answer
C. Gynecomastia
Explanation
Gynecomastia is a common temporary benign enlargement of the male breast. It is characterized by the development of glandular breast tissue in males, leading to breast enlargement. This condition can occur due to hormonal imbalances, medications, certain medical conditions, or lifestyle factors. Unlike Paget's disease and infiltrating ductal carcinoma, which are forms of breast cancer, gynecomastia is not malignant. Fibroadenoma is also a benign breast condition, but it is more commonly found in females rather than males.
4.
Mild cases of gynecomastia will be visualized on the mammogram as a small circumscribed density ____.
Correct Answer
B. Posterior to the nipple in the subareolar area
Explanation
Mild cases of gynecomastia will be visualized on the mammogram as a small circumscribed density posterior to the nipple in the subareolar area. This means that the abnormal tissue growth associated with gynecomastia is located behind the nipple and within the area immediately surrounding it. This location is consistent with the typical presentation of gynecomastia, as the condition is characterized by the enlargement of breast tissue in males.
5.
A characteristic associated with gynecomastia is ____.
Correct Answer
A. A well-defined tender mass
Explanation
Gynecomastia is a condition characterized by the enlargement of breast tissue in males. One of the common characteristics associated with gynecomastia is the presence of a well-defined tender mass. This means that there is a noticeable lump in the breast area that is clearly defined and can be felt when touched. The tenderness suggests that there is some discomfort or pain associated with the mass. This characteristic helps to differentiate gynecomastia from other conditions that may cause breast enlargement in males.
6.
The most common type of breast cancer in the male is ____.
Correct Answer
C. Infiltrating ductal carcinoma (IDC)
Explanation
The most common type of breast cancer in males is infiltrating ductal carcinoma (IDC). This type of cancer starts in the milk ducts of the breast and then invades the surrounding breast tissue. Unlike ductal carcinoma in situ (DCIS), which is non-invasive, IDC is considered invasive and has the potential to spread to other parts of the body. Lymphoma and lobular carcinoma in situ (LCIS) are less common types of breast cancer in males.
7.
Infiltrating ductal carcinoma accounts for ____% of male breast cancer.
Correct Answer
D. 85
Explanation
Infiltrating ductal carcinoma is the most common type of breast cancer in both men and women. It is a type of breast cancer that starts in the milk ducts and then invades the surrounding breast tissue. Although male breast cancer is rare compared to female breast cancer, infiltrating ductal carcinoma accounts for a significant percentage of cases in men. Therefore, it is not surprising that it accounts for 85% of male breast cancer cases.
8.
The most common characteristic symptom of a male with breast cancer is ____.
Correct Answer
B. A painless subareolar lump
Explanation
The most common characteristic symptom of a male with breast cancer is a painless subareolar lump. Male breast cancer often presents as a painless lump underneath the nipple or areola. This lump is typically firm and doesn't cause any pain or tenderness. It is important for males to be aware of any changes in their breast tissue and seek medical attention if they notice any unusual lumps or changes.
9.
____ is a characteristic most likely associated with carcinoma.
Correct Answer
C. An area with irregular margins and hard on palpation
Explanation
Carcinoma is a type of cancer that is characterized by the abnormal growth of cells. An area with irregular margins and hardness on palpation is more likely to be associated with carcinoma because cancerous tumors often have irregular shapes and are firm to the touch. These characteristics can be indicative of the presence of malignant cells and the need for further investigation and diagnosis.
10.
A man’s likelihood of developing breast cancer is increased by ____.
(1) Klinefelter syndrome
(2) childhood radiation of the chest
(3) family history of breast cancer
Correct Answer
D. 1, 2 & 3
Explanation
The likelihood of a man developing breast cancer is increased by multiple factors. Klinefelter syndrome, a genetic condition where a male is born with an extra X chromosome, can increase the risk. Childhood radiation of the chest, such as for the treatment of lymphoma, can also increase the risk. Additionally, having a family history of breast cancer, particularly in close relatives like a mother, sister, or daughter, can increase the risk. Therefore, the correct answer is 1, 2 & 3, as all three factors contribute to an increased likelihood of developing breast cancer in men.
11.
An adult male with a suspicious mammogram and a firm unilateral nodule will be advised by his physician to ____.
Correct Answer
A. Undergo a biopsy
Explanation
Given the symptoms of a suspicious mammogram and a firm unilateral nodule, the physician is likely to advise the adult male to undergo a biopsy. A biopsy is a medical procedure in which a small sample of tissue is taken from the affected area for further examination and diagnosis. This is necessary to determine if the nodule is cancerous or benign, and to guide appropriate treatment decisions. Waiting to observe the nodule further may delay diagnosis and potentially worsen the condition. Switching medications or reducing cholesterol levels would not be the appropriate course of action in this case.
12.
The incidence of breast cancer in men ____.
Correct Answer
A. Increases with age
Explanation
The incidence of breast cancer in men increases with age. This means that as men get older, their risk of developing breast cancer also increases. This could be due to various factors such as hormonal changes, genetic predisposition, or exposure to certain risk factors over time. However, the exact relationship between age and breast cancer incidence in men is still being studied and understood.
13.
A predisposition to breast cancer is inherited in ____.
Correct Answer
C. Both men and women
Explanation
A predisposition to breast cancer is inherited in both men and women. This means that individuals can inherit certain genetic factors that increase their risk of developing breast cancer, regardless of their gender. While breast cancer is more commonly associated with women, men can also be affected by this disease. Therefore, both men and women can inherit a predisposition to breast cancer.
14.
About _____% of male breast cancer patients are treated by mastectomy.
Correct Answer
B. 80
Explanation
Approximately 80% of male breast cancer patients are treated by mastectomy. This means that out of every 100 male breast cancer patients, 80 undergo mastectomy as a treatment option. Mastectomy involves the surgical removal of the breast tissue and is a common treatment for breast cancer in both men and women.
15.
The most important factor influencing prognosis in male breast cancer ____.
Correct Answer
C. Status of the axillary lympH nodes
Explanation
The status of the axillary lymph nodes is the most important factor influencing prognosis in male breast cancer. This is because the presence or absence of cancer cells in the lymph nodes indicates whether the cancer has spread beyond the breast. If cancer cells are present in the lymph nodes, it suggests a higher risk of metastasis and a poorer prognosis. Therefore, assessing the status of the axillary lymph nodes is crucial in determining the stage of the disease and guiding treatment decisions.
16.
The principle reason for the use of mammography in male patients is to distinguish ____.
Correct Answer
B. Gynecomastia from male breast cancer
Explanation
Mammography is used in male patients to distinguish gynecomastia from male breast cancer. Gynecomastia refers to the enlargement of male breast tissue, which is usually benign. However, male breast cancer is a rare but possible condition that can also cause breast enlargement in males. Mammography helps to differentiate between these two conditions by providing detailed imaging of the breast tissue, allowing for the detection of any suspicious masses or abnormalities that may indicate the presence of breast cancer.
17.
The ____ view is an alternative for the Cranio-caudal view and may be substituted.
Correct Answer
A. Caudo-cranial (From Below FB)
Explanation
The caudo-cranial view is an alternative for the cranio-caudal view and may be substituted. This view involves imaging the patient from below, with the X-ray beam directed towards the head. It provides a different perspective and can be useful in certain situations where the cranio-caudal view may not be feasible or effective.
18.
A
basic rule in male breast radiography is ____.
Correct Answer
D. The nipple should always be projected in profile
Explanation
In male breast radiography, the nipple should always be projected in profile. This is important because it allows for accurate positioning and alignment of the breast tissue during the imaging process. By projecting the nipple in profile, it ensures that the entire breast is captured in the image and minimizes the risk of missing any abnormalities or lesions that may be present. Therefore, it is a basic rule in male breast radiography to always project the nipple in profile.
19.
For
the Cranio-caudal projection, the mammographer should stand on ____.
Correct Answer
A. The medial side of the breast being examined
Explanation
The mammographer should stand on the medial side of the breast being examined for the Cranio-caudal projection. This position allows for optimal positioning and compression of the breast during the imaging process. Standing on the medial side ensures that the mammographer has better access and control over the breast, resulting in better image quality and accuracy of the examination.
20.
The
patient’s ____ is likely to obstruct the X-ray beam when the obese patient is
positioned for theCaudo-Cranial
(FB) view.
Correct Answer
A. Abdomen
Explanation
The patient's abdomen is likely to obstruct the X-ray beam when the obese patient is positioned for the Caudo-Cranial (FB) view. This is because the abdomen is a large and dense area of the body, especially in obese patients, which can block or absorb a significant amount of the X-ray beam. This obstruction can make it difficult to obtain clear and accurate images of the desired area, hindering the effectiveness of the X-ray examination.
