How common is breast cancer?

According to the World Health Organization, breast cancer is the most common form of cancer among women in the world. In fact — and you’ve probably heard this chilling statistic before — 1 in 8 women will be diagnosed with breast cancer in their lifetime.

The good news? Most breast cancer is extremely treatable when caught early. That’s why we’re committed to sharing these helpful self-exam and prevention tips with our audience so you can be armed with the knowledge to spot it and make a plan for what to do if you find something. 

How often should you self-check for breast cancer?

The goal is to check yourself once a month. Ideally, perform the exam a week after the end of your cycle when your breasts are their least swollen. However, if it’s easier to remember to do it on a specific date each month, go with that tactic! Checking is always better than not checking. One of the biggest blocks to self checks is fear. If that sounds like you, remember this: most cancer that’s caught early is very treatable.

How can I check myself for breast cancer?

1. Check yourself out. Examine your breasts in the mirror for any visual abnormalities, like lumps or sudden changes to the shape or nipples. 

2.  Put one hand behind your head, and the other on your breast. Using three fingers, make little circles with varying degrees of pressure. Drag your fingers across your breast tissue to get to the next spot instead of picking up or lifting to maximize coverage. 

3. Don't forget the armpits. The underarm and side boobs are important spots to examine, so don't neglect them in your self-check. This is where your lymphatic system is, so it's a common place for cancer to develop.

4. End with a nipple squeeze. If there is any pain or discharge, see a doctor right away.
