An Unexpected Diagnosis
In December 2024, Richard Loud, a mechanical engineer and experienced distance runner from upstate New York, received a diagnosis of stage II invasive ductal carcinoma of the right breast. His experience illustrates several important issues in male breast cancer, including delayed recognition of symptoms, the value of specialized oncology consultation, and the growing importance of clinical research designed specifically for men.The initial discovery occurred several months earlier while Loud was preparing for a long-distance run. As part of his routine, he applied protective guards to prevent nipple chafing and noticed a small lump beneath his right nipple, approximately the size of a lentil. Believing it was a benign cyst, he initially chose not to seek medical evaluation. By late November, however, he developed discomfort beneath his arm and discovered a second, larger lump in the axillary region. His awareness that breast cancer could occur in men, and that regional lymph nodes could become involved, prompted him to contact his physician.
Diagnostic mammography and ultrasound identified suspicious findings, leading to a biopsy. Two days after Christmas, Loud learned that he had breast cancer. Subsequent staging examinations, including magnetic resonance imaging, computed tomography, and a nuclear bone scan, found no evidence of distant metastatic disease. His physicians classified the cancer as stage II and advised that treatment could proceed with curative intent.
For Loud, the distinction between localized or regional disease and distant metastasis was psychologically significant. Although the diagnosis remained serious, the staging results provided a more favorable clinical outlook and allowed him to begin evaluating available treatment strategies.
Seeking Specialized Expertise
Loud initially consulted with oncology specialists affiliated with Saratoga Hospital and Glens Falls Hospital. The proposed treatment sequence included approximately 16 weeks of chemotherapy, followed by surgery and radiation therapy. Before committing to that approach, he elected to obtain a second opinion at Dana-Farber Cancer Institute in Boston, particularly because of its established clinical interest in male breast cancer.
At Dana-Farber, Loud met with medical oncologist Jose Pablo Leone, MD, who discussed the limitations of existing evidence concerning optimal treatment strategies for men. Although endocrine therapies and other breast cancer treatments are routinely prescribed to male patients, many treatment recommendations have historically been extrapolated from studies involving predominantly female populations.During this consultation, Dr. Leone introduced Loud to the ETHAN clinical trial, which was investigating endocrine-based treatment approaches in male breast cancer. Loud met the eligibility requirements and enrolled as participant number nine. He was assigned to a treatment arm involving newer therapeutic approaches rather than tamoxifen alone.
The decision to participate represented an important change in Loud's understanding of his diagnosis. Instead of viewing treatment exclusively as a personal medical necessity, he began to appreciate the opportunity to contribute to research that might improve clinical decision-making for future male patients. As he explained during his interview, participation allowed him not merely to benefit from medical research but to become part of the research process itself.
Nineteen Weeks of Clinical Treatment
Loud began the ETHAN treatment protocol in February 2025 and completed the 19-week treatment phase on June 24. Surgery followed on June 30, allowing the clinical team to evaluate the treated tissue and assess his response. The close sequencing of treatment and surgery was an important component of the protocol as he described it.Throughout the treatment period, Loud continued maintaining an unusually high level of physical activity. A committed marathon runner, he had specifically asked Dr. Leone whether he could continue training and competing. His physician encouraged him to remain physically active within his tolerance, and Loud ultimately completed four marathons while participating in the trial.
This achievement did not mean that treatment was without adverse effects. Loud described fatigue, gastrointestinal symptoms, reduced running speed, and a gradual decline in endurance. Nevertheless, he reported that the side effects remained manageable and did not prevent him from continuing most of his established activities.
His experience provides an individual example of maintaining physical activity during cancer treatment, although it should not be interpreted as evidence that comparable exercise intensity is appropriate for all patients. Exercise tolerance varies considerably according to disease characteristics, treatment regimens, cardiovascular health, and other clinical factors.
Evaluating Treatment Response
Following completion of the trial and surgery, Loud's medical team reviewed his response and discussed the need for additional systemic treatment. According to his account, Dr. Leone considered the response sufficiently favorable to support a treatment plan that did not include chemotherapy.
Several clinical characteristics contributed to this discussion. Loud reported that his tumors were classified as grade one and that an Oncotype DX assay produced a recurrence score of 12, within the low-score range. These findings, considered alongside his clinical response and other factors, helped inform the decision regarding subsequent treatment.
Loud was offered continued endocrine therapy with either tamoxifen or anastrozole. He selected tamoxifen, principally because of its longer history of use in male breast cancer management. At the time of his November 2026 interview, he remained on the medication and described hot flashes, persistent changes in body composition, and some reduction in athletic performance as his principal ongoing concerns.
His favorable experience should be understood within the context of an individual clinical course. It does not independently establish the effectiveness of the investigational treatment arm or suggest that chemotherapy can be safely omitted in other patients without appropriate clinical evaluation.
Family History and Hereditary Risk
Loud's diagnosis also brought increased attention to cancer risk within his family. His father and an older brother had histories of prostate cancer, while his paternal grandmother had experienced Hodgkin lymphoma. Loud underwent hereditary cancer genetic testing and reported that no relevant pathogenic mutation was identified.
Approximately six months after his diagnosis, a niece was diagnosed with stage II breast cancer at age 36. This development reinforced the family's concern about possible inherited or familial susceptibility, despite Loud's negative genetic testing results.
His adult children subsequently became more attentive to cancer surveillance. Loud encouraged his son to recognize and promptly report unusual breast changes, while his daughter pursued genetic testing and a formal breast cancer risk assessment. Based on her assessment and family history, her clinicians initiated earlier breast surveillance, including magnetic resonance imaging.
These experiences illustrate the importance of evaluating family history alongside genetic testing results. The absence of an identified pathogenic mutation does not necessarily exclude elevated familial risk, and individualized surveillance recommendations may remain appropriate.
Life After the ETHAN Trial
By November 2026, Loud had been out of the active ETHAN treatment phase for approximately 16 months. He continued receiving tamoxifen and attending oncology follow-up appointments at six-month intervals, along with annual mammographic surveillance.He also remained interested in the trial's continuing development, particularly discussions concerning the possible incorporation of circulating tumor DNA testing. Although this testing had not been part of his original treatment protocol, he understood that protocol amendments might create opportunities for additional research involving previous participants. Whether such testing would become available or clinically relevant to his circumstances remained unresolved at the time of the interview.
Outside his medical care, Loud continued working as a mechanical engineer specializing in industrial noise control for power-generation facilities. Having spent more than 38 years with GE and GE Vernova, he described himself as approaching retirement eligibility while remaining professionally engaged.
Running also continued to occupy an important place in his life. Shortly before the interview, he completed the 2026 New York City Marathon. Although he acknowledged that his speed and endurance had not fully returned to their previous levels, he continued participating in the sport that had inadvertently led to his initial cancer discovery.
The Broader Significance of His Experience
Richard Loud's experience contributes to a broader discussion about the need for greater male representation in breast cancer research. His decision to enter the ETHAN trial reflects the importance of developing clinical evidence that addresses the biological characteristics, therapeutic responses, and survivorship needs of men rather than relying exclusively on findings derived from female patient populations.
His account also emphasizes the practical importance of symptom recognition, timely diagnostic evaluation, specialized consultation, and informed participation in treatment decisions. The initial lump that Loud discovered during routine marathon preparation might easily have remained unexamined for a longer period. The subsequent appearance of axillary symptoms ultimately prompted the diagnostic investigation that identified his cancer.For the Male Breast Cancer Global Alliance, his story offers a useful perspective on survivorship as an ongoing process involving treatment, surveillance, family education, and adjustment to long-term physical changes. Loud's participation in clinical research added another dimension to that process by connecting his individual experience with the development of future therapeutic knowledge.
As Loud explained, one of the most meaningful aspects of participating in the trial was knowing that the information generated might contribute to better options for patients diagnosed after him. His experience therefore represents both a personal account of male breast cancer treatment and an example of how patient participation can support the continuing advancement of clinical science.
