Do not start smoking or stop NOW! Smoking cigarettes is one of the most important risk factors for most cancers, but also for a heart attack or stroke. Exercise daily for at least 30 minutes physically – ideally with an endurance sport such as cycling, running or swimming. But going for a walk or window shopping are also a welcome opportunity! Do not eat one-sidedly and eat fruits and vegetables every day. Watch your weight – neither too much nor too little is advisable. Check your own breast every month – if you notice any changes, talk to your gynecologist immediately. Have your gynecologist or your gynecologist check your breast once a year. Go regularly to the mammography preliminary examination from the age of 45.
