New research has suggested that vitamin and calcium supplements could help prevent cancer in the long run.
Damaged DNA could be healed with the help of supplements using a process involving 200 or more proteins, scientists working on the study have concluded.
The study, presented in the American Association for Cancer Research annual meeting in Washington DC compared 268 breast cancer patients and 457 healthy women.
Professor Jaime Matta, from the Ponce School of Medicine in Puerto Rico, said that the supplements did not show immediate effect but stressed that there was “a long-term effect in terms of breast cancer reduction”.
He said: “This process involves at least five separate pathways and is critical for maintaining genomic stability. When the DNA is not repaired, it leads to mutation that leads to cancer.”
Different kinds of vitamin supplements contributed to reducing the risk of breast cancer by about 30% while calcium supplements accounted for a 40% reduction.
“We’re not talking about mega doses of these vitamins and calcium supplements, so this is definitely one way to reduce risk,” said Prof Matta.
