Breast changes during pregnancy and breastfeeding can be a cause of anxiety, but a new guide from Breast Cancer Care aims to reassure pregnant and new mothers, and offer them advice.

Supporting the campaign is broadcaster and mother Mariella Frostrup. She said: "We all have questions and uncertainties about how our bodies are changing during pregnancy, especially if it's the first time. Your breasts can look and feel very different and it's natural to feel worried."

Helen Graham, breast health specialist nurse at Breast Cancer Care, said: "The vast majority of breast changes women experience will be benign, as breast cancer in women of child-bearing age is uncommon - and even more uncommon during pregnancy."

Copies of the new guide on breast changes associated with pregnancy and after giving birth are available by visiting www.breastcancercare.org.uk or by calling 0808 800 6000.

Fruit for health
People who eat a diet high in fruit and low in meat reduce their risk of developing colon cancer, according to American researchers. A team at the University of North Carolina interviewed 725 people who had undergone colonoscopies, and found that 203 had been diagnosed with adenomas: polyps that often turn into tumours.

Those who ate large or moderate amounts of meat were 70% more likely to have had a polyp than those who ate a lot of fruit but little meat.

Strength to endure
Men who have had a coronary artery bypass may be at increased risk of bone fractures in the year following surgery.

Research has shown that bone mineral content decreases significantly in men after bypass surgery. American doctors evaluated bone changes in 26 men aged 50 to 79 three months after surgery, and then again after one year. They found bone mineral density had gone down in the arms, pelvis and all over the body in the first three months. After a year, bone mineral density in the total body and the legs was still significantly down, and was also decreased in the arms.

Dr Larry Miller of the Virginia Polytechnic Institute, who led the research, said the risk of fractures could be minimised by doing appropriate exercise after surgery - though it was important to do this with a doctor's guidance.
