Breast cancer can start at any age, but the majority of cases are diagnosed after the age of 50. It is important to note, however, that breast cancer can occur in younger age groups, even in teens and young adults.
According to the American Cancer Society, “about 11 percent of all new cases of breast cancer in the United States are found in women younger than 45 years of age. The majority of these occur in women between the ages of 30 and 39.” In addition, “breast cancer is the most common cancer in women ages 15 to 29, and the second most common cancer overall in this age group.”
It is important to note that, although breast cancer is more common in older age groups, all women should be aware of the possibility of it occurring at any age. Regular screening and self-examinations are recommended for all women, regardless of age, to help detect breast cancer in its early stages. Additionally, it is important to be aware of the signs and symptoms of breast cancer, such as a lump in the breast, nipple discharge, or changes in the skin of the breast or nipple, and to seek medical attention if any of these are present.
Overall, breast cancer can occur at any age, but is most common in women over the age of 50. However, it is important for all women to be aware of the possibility of it occurring and to take the necessary steps to detect it in its early stages.
