How does a mammogram benefit women's health?

A mammogram is an essential tool in women's health primarily because it screens for breast cancer. This screening process involves taking X-ray images of the breasts to detect any abnormal growths or changes that could indicate the presence of cancerous tissue. Early detection of breast cancer through mammography significantly improves the chances of successful treatment and can reduce mortality rates associated with the disease.

The importance of screening cannot be overstated, as many women may not experience symptoms in the early stages of breast cancer, making routine mammograms crucial for early intervention. Additionally, mammograms can also detect other breast conditions that may not be cancerous but still require medical attention.

Other choices, while relevant to health, do not pertain to the specific function of a mammogram. For instance, measuring hormone levels and monitoring bone density are conducted through different diagnostic tests, and identifying STIs involves various screening methods unrelated to mammography. Thus, the correct choice highlights the primary purpose of mammograms in safeguarding women's health by focusing on early detection of breast cancer.
