Father of Three Diagnosed with Rare Breast Cancer at 53

In 2013, Jacob Johnson from Fort Collins, Colorado, found out he was a BRCA2 gene carrier, linked to a high risk of cancer. Ten years later, at 53, he was diagnosed with a rare and aggressive type of breast cancer in his right breast.

Despite undergoing regular mammograms for over a decade, Johnson was shocked by the diagnosis. He initially thought the mass would be benign, but tests confirmed invasive micropapillary carcinoma (IMPC), a serious cancer subtype.

The National Cancer Institute explains that BRCA1 and BRCA2 genes help repair damaged DNA. However, mutations can increase cancer risks as the body struggles to fix DNA damage. After his diagnosis, Johnson had a double mastectomy in January 2026 and began chemotherapy, experiencing side effects from drugs like Cytoxan and doxorubicin, known as the “red devil.”

Johnson’s wife, Kimberly, notes the challenge has been his physical changes and reduced energy, impacting his ability to engage with their children. Male breast cancer is rare, making up less than 1% of cases in the US. Johnson encourages men to monitor health changes and prioritise screenings, especially with a family history of cancer.

Kimberly shares his story on TikTok to raise awareness. This experience has made her more vigilant about her own health, prompting regular check-ups. Their children will undergo testing when of age, though their eldest daughter has tested negative.

Johnson stresses the value of genetic testing and early detection, crediting his mother’s research into family history for his early diagnosis, which he believes saved his life.
