Osteoporosis and Breast Cancer

Osteoporosis literally means porous bones. The result is that the bones can become thin or snap. Osteoporosis cannot be cured and often is not found until after bones break. It affects half of women over 50 and one in five men in that age range and some people who receive treatment for breast cancer are at an increased risk of ostoeporosis, however, treatments are available to try to keep bones strong and less likely to break.

Women who have not gone through the menopause before they are treated for breast cancer have an increased risk of osteoporosis. Indeed, chemotherapy can cause an early menopause and a rapid, significant reduction in bone density and result in osteoporosis.Even women who have been through the menopause may be at increased risk of osteoporosis because of the hormone therapies they take for breast cancer.

balanced her 2.jpgI am being treated with letrozole for my breast cancer. My tumour was of the fast growing HER2 positive variety. The letrozole is one of the drugs that reduces the amount of oestrogen circulating in my body and this could result in osteoporosis. I have my bone density checked with a bone density scan and, so far, I do not show signs of osteoporosis. Generally speaking, people with a good bone density before getting treatment for breast cancer are less likely to develop osteoporosis while taking an aromatase inhibitor such as letrozole.

I have been careful to put some simple lifestyle choices to help keep my bones strong and healthy. I ensure that, although I am vegetarian, I have a well-balanced diet. Although dietbalanced-diet changes will not cure bone defects, it may stop them osteoporosis getting worse. Eating meals that incorporate a wide variety of foods including fruit and vegetables, carbohydrates, milk and dairy products and proteins help achieve this. As a general rule it is recommended that we eat at least five portions of fruit and vegetables a day. You would be amazed how many people, including vegetarians, do not manage this! I have also significantly reduced my alcohol intake and the amount of fizzy drinks I take.

Calcium is a vital mineral for teeth and bones. It gives them strength and rigidity. Most of the calcium found in our bodies is in our bones. Dairy produce is our main source of calcium. People  can usually get enough calium through a healthy diet that includes dairy products. If your diet did not include dairy produce you would need to ensure you got calium from another source such as a calcium supplement.

I also have to bear in mind that vitamin D is needed to help my body absorb calcium. The best source of vitamin D is sunlight. Human bodies use the sunshine to make vitamin D in the skin. The vitamin D is fat-soluble and the body stores it for use in the winter months. balanced sunWe only need to be out in the sun for about quarter of an hour a day during the summer months to give most people enough vitamin D for the whole year. So a walk, some gardening or a round of golf should make sure we get enough vitamin D. In addition to that, margarine, egg yolks and oily fish also contain vitamin D.

Regular weight-bearing exercise is also important to put force through the bones. This helps stimulate growth and strength and keep bones strong and healthy. Such exercise includes skipping, aerobics, tennis, and dancing are good bone building activities, even a brisk walk can be of benefit to bones. I try to do some exercise at least three times a week in order to combat the cancer-related fatigue I suffer and the potential for weight gain that my medication induces. I really try very hard to make sure that I do not add osteoporosis to my list of worries.
