Arantxa was diagnosed with breast cancer at the young age of 25. Today, we share her story of hope and reflect on the journey many survivors have faced—the courage to move forward and confront an oncological diagnosis.
Here is her story:
I was diagnosed with breast cancer at 25.
Ironically, I was graduating as a radiologic technologist—a field where we are trained and familiar with such conditions—but I never imagined my first contact with it would be as a patient rather than as a professional.
I won’t deny it—it’s not an easy diagnosis to digest. One is never truly ready for that kind of news.
What I would tell anyone who has just received this diagnosis is, first: everything passes. Just as we are receiving life-changing news in that moment, there will also come a day—if we hold onto faith—when we’ll hear that we are cancer-free. And when that day comes, there’s no greater satisfaction.
You have to hold on to everything you can—your support network, the people who are like angels life puts in your path, whether they’re doctors, healthcare professionals, or anyone you meet during the process. All of that helps. The way to get through it is to face it one day at a time.
My first stage of treatment was chemotherapy, which lasted six months. Thanks to God, the results were excellent. Afterwards, I had surgery, which went quite smoothly.
The final and one of the most important stages to prevent recurrence was radiation therapy. Given my academic background, the first place I thought of was RSiglo XXI, because I knew that if I could be treated there, I would not only receive world-class treatment comparable to any first-world country, but also excellent care and human warmth to ensure the best possible outcome.
During treatment, not every day was easy or positive—there were ups and downs. Here, I found not only clinical support but also emotional and human support.
Being treated at Radioterapia Siglo XXI was truly a blessing in my journey.Read her full testimonial at enlace.
🌸 Beyond the Diagnosis: What Every Young Woman Should Know About Breast Cancer
The testimony of a 25-year-old woman diagnosed with breast cancer reminds us of a reality more and more specialists are seeing: cancer has no age. Although most cases occur after age 40, the number of young women diagnosed has been rising in recent years.
En At Radioterapia Siglo XXI,,we support patients of all ages with a comprehensive approach that combines advanced technology, clinical precision, and deep human commitment..
Can I Be Diagnosed with Breast Cancer at a Young Age?
Yes. Although breast cancer is more common in women over 40, it can also appear in younger women. In fact, between 5% and 7% of cases are diagnosed before age 40, according to international data.
In young women, this cancer type can be more aggressive due to genetic, hormonal, or lifestyle factors. That’s why early detection and medical consultation at the first sign of change are essential.

- Family history of breast or ovarian cancer (mother, sister, grandmother)
- Hereditary genetic mutations such as BRCA1 or BRCA2

However, many women diagnosed have no known risk factors—so regular medical monitoring is key.

Early detection saves lives. In general:
- From age 20: Monthly breast self-exam, ideally one week after menstruation.
- From age 25: Annual medical evaluation with a clinical breast exam.

In young women, dense breast tissue can make mammogram readings harder, so specialists may suggest complementary imaging such as MRI.
When Is Radiation Therapy Appropriate for Breast Cancer Patients?
Radiation therapy is an essential part of breast cancer treatment, especially after breast-conserving surgery or when reducing the risk of recurrence.
At Radioterapia Siglo XXI, we use advanced techniques that allow us to precisely treat the affected area while protecting healthy tissue, such as:
- Deep Inspiration Breath Hold (DIBH): A technique that controls breathing to move the heart away from the radiation field, minimizing cardiac risk.
- Image-Guided Radiation Therapy (IGRT): Ensures radiation is delivered exactly to the target area in every session.
- 3D Planning and Intensity-Modulated Radiation Therapy (IMRT): Optimize the radiation dose, adapting it to the shape of the tumor and surrounding organs.
These technologies allow for safer, more precise, and personalized treatments—with excellent clinical outcomes and a better quality of life for each patient. Other Common Questions About Breast Cancer in Young Women
