Jacob Johnson, a 53-year-old father of three from Fort Collins, Colorado, was diagnosed with a rare and aggressive form of breast cancer in December 2025. Despite being aware of his genetic predisposition due to a BRCA2 gene mutation and undergoing annual mammograms for 12 years, Johnson received the unexpected diagnosis on his 53rd birthday. His case highlights the growing, though often overlooked, risk of breast cancer in men and the critical role of genetic testing and early detection.

Why it matters

For decades, breast cancer has been largely considered a women's health issue. Johnson's story is changing that perception and emphasizing the importance of expanding genetic testing and promoting awareness of male breast cancer symptoms. His experience also underscores the need for continued vigilance, even with preventative measures in place, as he was diagnosed with a rare and aggressive subtype despite his annual screenings.

The details

Johnson learned he carried the BRCA2 gene mutation in 2013, following a strong family history of the disease. This gene, along with BRCA1, is responsible for repairing damaged DNA, and a mutation in either gene significantly increases the risk of certain cancers, including breast cancer in men. Despite being aware of his genetic predisposition, Johnson was diagnosed with invasive micropapillary carcinoma (IMPC), a rare and aggressive subtype of breast cancer.

  • In 2013, Johnson learned he carried the BRCA2 gene mutation.
  • For 12 years, Johnson underwent annual mammograms.
  • In December 2025, Johnson received his breast cancer diagnosis on his 53rd birthday.
