London: Women with breast cancer have a better chance of surviving breast cancer if they don`t have a mastectomy, a major study has found.Those aged over 50 who have only the lump removed, followed by radiotherapy, are almost a fifth more likely to survive the illness than patients who lose the whole breast.Many breast cancer patients choose to have a mastectomy thinking it will remove the tumours as quickly as possible and give them the best chance of survival.But a ten-year research project by researchers from Duke University in North Carolina has found that a less radical form of treatment - breast conservation surgery - is more effective.It involves taking away the affected lump and then administering high doses of radiotherapy over a course of five or six weeks to ensure any remaining cancerous cells are killed.The researchers looked at the records of 112,154 women diagnosed with breast cancer between 1994 and 2004.
