Many women remain confused about the right way to check their breasts for early signs of cancer. Experts say there is no evidence that rigorous monthly “self-examination” reduces breast cancer deaths and it can lead to unnecessary biopsies.

Two large studies looking at a total of more than 388,000 women found that death rates from breast cancer were the same among women who rigorously self-examined as those who did not, while there were almost twice the number of biopsy operations in the self-examination group.

According to some experts, the best way for a woman to check her breasts is not to follow a strict examination routine, but to get to know what is normal, and feel them regularly for signs of any changes.
