Final answer:
The recommended time for a monthly breast self-exam is right after the period ends during the follicular phase of the menstrual cycle, as breasts are less tender and changes can be detected more accurately.
Step-by-step explanation:
The best time to perform a monthly breast self-exam is right after the period ends, when your breasts are less tender. This is typically in the follicular phase of the menstrual cycle when hormonal fluctuations have subsided and the breast tissue is less likely to be swollen or tender, making it easier to identify any changes or lumps. Performing the exam at this time allows for better consistency in terms of breast texture and can help in more accurately detecting any unusual changes. It's important for young women and college students to get in the habit of performing these exams to become familiar with what is normal for their bodies and to detect any potential indications of breast cancer early on, which is crucial for a better outcome.
