Only five to 10 per cent of breast cancers are inherited. However, be extra vigilant if a close female relative (mother, sister or daughter) was diagnosed under the age of 50. The Pill very slightly increases breast cancer risk but this disappears once you stop taking it. HRT also raises the likelihood but this falls back to normal within five years of stopping HRT. Not having children, or having them later in life, increases likelihood, as does being overweight after the menopause. Drinking alcohol also raises the risk. If you drink alcohol every day, your risk increases by seven per cent for each daily drink, according to a major study into alcohol and smoking. Keeping to a healthy weight after the menopause, exercising, and eating a balanced diet rich in antioxidants are advisable. Check your breasts regularly for changes.
