4. Breast cancer response

Please bear in mind that cancers of any kind are rare. There are many health avenues to explore before going down this road, but it is always good to be cautious when it comes to lumps that can appear under your arms. All women should perform regular self-exams on their breasts as over 40% of breast cancers are self-detected. An easy way to remind yourself to do these is to schedule the exam into your day as you would anything else. Breast exams are best done once a month at the same time of the month as the feel of your breasts changes throughout the month because of hormones. There are apps available that teache you the best way to perform self-examinations and schedules an automatic monthly reminder to keep you on top of things.
