Summary
Brief summary (as posted)
RATIONALE: Steroid therapy, such as mometasone furoate, may prevent radiation dermatitis caused by radiation therapy. It is not yet known whether mometasone furoate is more effective than a placebo in preventing radiation dermatitis. PURPOSE: This randomized phase III trial is studying mometasone furoate to see how well it works compared to a placebo in preventing radiation dermatitis in patients undergoing radiation therapy to the breast or chest wall for invasive breast cancer or ductal carcinoma in situ.
