Tina Knowles, mother of Beyoncé and Solange, was diagnosed with stage 1A breast cancer after delaying her mammogram for four years during and after the COVID-19 pandemic. Following successful surgery to remove tumors in both breasts, she is now cancer-free and advocates for regular screenings.

Breast cancer screening recommendations:

  • Ages 40-44: Option for annual mammograms
  • Ages 45-54: Annual mammograms required
  • Ages 55+: Mammograms every other year
  • Continue screening while in good health with 10+ years life expectancy

Key breast cancer statistics:

  • Most common cancer in U.S. females (after skin cancer)
  • 300,000+ new cases expected in 2025
  • 42,000 estimated deaths in 2025
  • 13% lifetime risk for U.S. women
  • Median age at diagnosis: 62 years

Common symptoms:

  • Breast lump
  • Underarm lump
  • Changes in breast shape or size
  • Nipple changes

Treatment options:

  • Surgery
  • Radiation therapy
  • Chemotherapy
  • Immunotherapy
  • Hormone therapy
  • Targeted therapy

Important disparities:

  • Black women face higher death rates
  • Higher risk of triple-negative breast cancer
  • Greater prevalence of risk factors (obesity, heart disease, diabetes)
  • Access barriers to screening and treatment
  • Environmental and social factors contribute to outcomes

Early detection significantly improves survival rates. Mammograms can miss 20-30% of cancers, making regular screenings crucial. Women should seek second opinions if needed and ensure timely access to preventative care.

Young women should note that while breast cancer is less common under 45, it can be more aggressive and harder to treat. Those with a 20%+ lifetime risk should begin screening before 40.

Medical experts emphasize that annual mammograms reduce both mortality risk and treatment intensity. All women deserve access to quality screening and care, regardless of background or socioeconomic status.
