The document discusses risk factors for breast cancer and aims to identify the age group at highest risk. A questionnaire assessing risk factors was administered to 600 women across 5 age groups. Results found that the percentage of women at high risk of breast cancer began increasing dramatically at age 35, peaking between ages 35-44. This suggests that 35 years old marks a border age where risk starts increasing. The conclusion is that women aged 35 and older should undergo regular screening as an important preventative measure against breast cancer.
