A glass of milk a day could prevent the spread of breast cancer to bones, according to new research.
Researchers at the Anzac Research Institute in Australia found that calcium deficiency could increase the tendency of the breast cancer cells to attack bone and suggested that a strong skeleton was the key to fighting the killer disease.
Published in an October issue of Cancer Research journal, the conclusions called for more research into how calcium and vitamin D status influence progression to metastatic disease and if deficiencies are important in breast cancer patients.
Senior author Colin R Dunstan said that many older women did not ingest enough calcium or vitamin D in their diet.
"These women could be at increased risk for the devastating effects of bone metastases," he added.
The study revealed that 70 per cent of patients with advanced breast cancer develop secondary tumours in the bone, leading to further pain and illness.
Cancer Research UK states that about 44,000 women a year are diagnosed with breast cancer.
