A nurse is reinforcing teaching with a client about breast self-examinations. Which of the following statements by the client indicates an understanding of the teaching?

"I will perform breast exams the day my period begins."  This is because the breasts are least likely to be tender or swollen during this time, which can make it easier to detect any lumps or other changes. 

Choice A is not correct because the recommended frequency for performing breast exams is every month, not every other month. 

Choice B is not correct because skin dimpling can be a sign of breast cancer and should be reported to a healthcare provider. 

Choice C is not correct because it is normal for one breast to be slightly larger than the other.
