At just 26 years old, Andrea de Armas discovered a lump in her breast while showering and initially thought it might be a simple cyst. With no known family history of breast cancer and the start of her rigorous physician assistant graduate program just days away, she sought medical evaluation. What followed was a challenging diagnostic process that included imaging and a biopsy, leading to a life-changing diagnosis of invasive ductal carcinoma. Her story, highlighted in recent coverage during Breast Cancer Awareness Month, underscores the importance of self-advocacy, especially for young women whose concerns are sometimes dismissed.
The Discovery of the Lump and Initial Concerns
Andrea de Armas, then a healthy and active 26-year-old preparing to begin PA school, noticed the lump on the outside of her breast. It was not tender or painful, so she assumed it was likely benign. Still, she decided to get it checked before her program started. During an early ultrasound visit, she felt the technician was skeptical and dismissive, creating an uncomfortable experience that left her feeling belittled. A radiologist reviewing the scan, however, took a different approach and recommended an immediate biopsy.
This contrast in care highlighted a common issue: young women are often told they are too young for breast cancer. According to the American Cancer Society, about one in 10 new breast cancer diagnoses occur in women under 45, while roughly one in 1,344 women in their 20s receive a diagnosis. Incidence rates have been rising by about 1% per year, with more new cases now appearing in women under 50 than over 50.
The Biopsy Process and Confirmed Diagnosis
Andrea de Armas pursued further evaluation at Baptist Health’s Herbert Wertheim Cancer Institute (Miami Cancer Institute). There, she underwent a mammogram, ultrasound, and breast biopsy. The results came back four days later—on the day before her PA program was set to begin—confirming the mass was malignant. She had invasive ductal carcinoma, the most common type of breast cancer, which starts in the milk ducts and can spread to nearby tissue.
The diagnosis was delivered around early May 2023 (specifically referenced as May 8 in related accounts). Further genetic testing revealed an inherited PALB2 mutation. This gene mutation increases lifetime risk for breast, pancreatic, and ovarian cancers in women (and prostate cancer in men). Lifetime breast cancer risk for PALB2 carriers is estimated around 35-60% depending on the study and population, significantly higher than the general population’s roughly 12%. Learning about the mutation brought Andrea a sense of relief and control, as it explained a possible origin and empowered her family to consider screenings.
Tailored Treatment While Pursuing Career Goals
Her medical team, including breast surgical oncologist Dr. Cristina Lopez-Penalver, personalized her care so she could continue school without major interruptions. On June 8, 2023, she had an outpatient lumpectomy to remove the tumor during a short break. Chemotherapy followed, scheduled early in the mornings (around 6:50 a.m.) so she could attend afternoon classes. During the December semester break, she underwent a bilateral mastectomy with reconstruction. Radiation was also part of the plan after positive findings in lymph nodes in some accounts.
Because her cancer was hormone-receptor positive, she began ongoing hormone therapy involving oral medication and monthly injections to suppress estrogen production from the ovaries. This approach lowers recurrence risk but can induce temporary menopause—a particular concern for young patients. She also faced earlier-than-expected fertility discussions. Throughout, her team emphasized that care is not one-size-fits-all and that personalizing treatment made it possible for her to stay on track academically.
Life After Treatment: Cancer-Free and Moving Forward
Andrea de Armas graduated from her physician assistant program in 2025. She began working in the field shortly afterward and celebrated her first anniversary on the job in September. Now 30 years old, she reports being cancer-free, with surgery and chemotherapy behind her. She continues hormone therapy and regular follow-up visits with her oncologist while living what she describes as a pretty normal life for her age.
In interviews and Baptist Health discussions around survivorship, she has spoken about the emotional side of the journey, the importance of support systems, and adjusting to physical changes. She stresses that knowledge is power and that people should advocate for themselves: if something feels wrong, get it checked, regardless of age.
Why This Story Matters for Breast Cancer Awareness
Andrea de Armas’s experience with the lump and subsequent biopsy serves as a reminder that breast cancer does not discriminate by age. Young women may face skepticism, denser breast tissue that complicates imaging, and unique challenges around fertility, body image, and balancing treatment with school or career. Her case also illustrates the value of genetic testing after a young diagnosis—information that can guide surgical choices (such as opting for bilateral mastectomy due to elevated second-cancer risk with PALB2) and inform relatives.
Recent coverage in October 2026 has brought renewed attention to her journey just as Breast Cancer Awareness Month highlights early detection and self-advocacy. Most breast biopsies are benign, but when imaging or a palpable finding warrants further investigation, prompt biopsy can lead to earlier diagnosis and better outcomes.
Her story continues to inspire others facing similar challenges, showing that with coordinated care, determination, and support, it is possible to pursue major life goals even during treatment.
