Correct Answer is A
Explanation
A. Three to seven days after menses stops. This is the best time to perform BSE as the breasts are least likely to be swollen and tender during this period.
B. Prior to the beginning of menses. Breasts are more likely to be swollen and tender before menstruation, which can make it harder to detect abnormalities.
C. On the second day of menstruation. During menstruation, hormonal changes can affect breast tissue, making the examination less reliable.
D. On the same day every month. For those with regular menstrual cycles, it is recommended to perform BSE a few days after menses stops for more accurate results.
Correct Answer is C
Explanation
A. Menopause is the cessation of menstruation and marks the end of the reproductive years.
B. Menarche is the onset of menstruation and does not describe a phase of the menstrual cycle.
C. The follicular phase begins at the end of menses and ends at ovulation. During this phase, follicles in the ovaries mature, and one dominant follicle is selected for ovulation.
