Sixty of these patients were over 70 years of age. The results were followed up from 4 years, 10 months to 10 years, 9 months or a mean of 7 years, 6 months. Elder patients (over 70 years old) had the same 5-year survival rate as those aged from 35 to 69 years old; they had a relatively higher 5-year survival rate than those under 35 years old. They have the same cancer stage distributions as those younger than 70 years old, and those with positive axillary lymph node have a higher mortality rate than those with negative node. Older age is not a contraindication to conventional breast cancer surgery. Elderly breast cancer patients should be treated as aggressively as younger patients.[SDGs]SDG3adult; aged; aging; article; axillary lymph node; breast cancer; cancer mortality; cancer staging; cancer surgery; female; human; lymph node metastasis; major clinical study; survival ratejournal article2-s2.0-0028023536
