Breast cancer remains a significant health issue, impacting millions worldwide. According to the World Health Organization, 2.3 million women were diagnosed with breast cancer in 2022, making it the most prevalent form of cancer in 157 out of 185 countries. The effects of breast cancer extend beyond those diagnosed, influencing friends, family, and colleagues, highlighting the importance of awareness and education about the disease.

Breast cancer occurs when cells in the breast grow uncontrollably. The breast consists of three primary components: lobules, ducts, and connective tissue. The type of breast cancer a person has is determined by which cells become cancerous. Most breast cancers originate in the ducts, which transport milk to the nipple, or in the lobules, which produce milk.

Each individual's experience with breast cancer is unique. However, the Centers for Disease Control and Prevention notes that the majority of cases begin in the ducts or lobules.

Gender is the leading risk factor for breast cancer, with the WHO reporting that 99% of cases occur in women. Age is another significant factor, as two-thirds of women diagnosed with invasive breast cancer are over 55 years old. Additionally, race plays a role, with breast cancer affecting more white women than women of other races. Women with dense breast tissue may also face a higher risk, as this can complicate the detection of lumps.

While most women cannot pinpoint an exact cause for their breast cancer, certain risk factors are beyond their control, such as gender and age. However, some controllable factors can be managed. The WHO highlights that excessive alcohol consumption and tobacco use are two modifiable risks.

Early detection is crucial in improving survival rates. The American Cancer Society reports that the five-year survival rate for breast cancers diagnosed at a localized stage is 99%. This statistic emphasizes the importance of regular screenings and awareness of breast health.
