According to the National Breast Cancer Foundation, every two minutes a woman somewhere in the world is diagnosed with breast cancer. And one woman in seven who lives to be 85 will develop breast cancer during her life. In addition, 1,600 men are expected to be diagnosed with breast cancer this year - 400 of whom are likely to die from the disease. The US foundation says that 70 per cent of breast cancers are found by self-examination - but not all lumps are detectable by touch. 'We recommend regular mammograms and monthly breast self-exams,' the foundation says. The good news is that not all lumps are a problem. Eight out of 10 aren't cancerous. 'If you find a lump, don't panic - call your doctor for an appointment,' the foundation advises. It says an early breast cancer detection plan should include: clinical breast examinations every three years from the ages of 20 to 39, and annually thereafter. It also advises: mammograms every one to two years for women aged 40 to 49, depending on previous findings; mammogram every year for women over; and a low-fat diet, regular exercise and no smoking.
