For many musicians, the ability to play an instrument or sing is more than a hobby—it is a deeply ingrained part of identity and emotional expression. A recent study published in JCO Oncology Practice sheds light on how breast cancer treatment can significantly affect this crucial aspect of life. According to the research, over a quarter of musicians who underwent treatment for breast cancer experienced difficulty with their musical endeavors. This phenomenon, termed "acute musical toxicity," offers a unique perspective on the long-term quality of life for survivors.

The study, led by Dr. Jessica F. Burlile of the Mayo Clinic in Rochester, New York, focused on a group often overlooked in cancer survivorship research: musicians. Using data from the Mayo Clinic Breast Cancer Registry, researchers distributed a nine-item Musical Toxicity Questionnaire to 4,075 participants. With a 46% response rate, 1,871 individuals completed the survey, and among them, 535 identified as musicians—defined as those who had played an instrument or sung within the past decade.

These 535 respondents reported a total of 802 unique musical activities. Among them, 27% described experiencing acute musical toxicity during or after treatment. The most frequently reported issue was decreased endurance, cited by 64% of those affected. Decreased accuracy followed, impacting 44% of respondents. These findings suggest that the physical and cognitive demands of musical performance can be particularly vulnerable to the side effects of cancer therapies.

I found this detail striking: chemotherapy was identified as the most detrimental treatment, with 71% of those who received it reporting negative impacts on their musical ability. This aligns with known side effects of chemotherapy, such as peripheral neuropathy, which can impair fine motor control—an essential skill for musicians. Additionally, radiation and surgery can lead to upper-extremity dysfunction, and aromatase inhibitors are known to cause joint pain, further complicating musical performance.

The study’s multivariable analysis revealed that chemotherapy and comprehensive regional nodal irradiation were both significantly associated with acute musical toxicity. Interestingly, age also played a role. Younger patients were more likely to report musical difficulties, with 34% of those under 40 and 36% of those aged 40 to 49 affected. This may reflect the higher likelihood of younger patients being actively engaged in music at the time of diagnosis and treatment.

To better understand the broader impact of treatment on well-being, the researchers also examined Patient-Reported Outcomes Measurement Information System (PROMIS) scores one year after diagnosis. They found that each additional point in mental and physical health scores was associated with a decreased likelihood of experiencing musical toxicity—by 8.6% and 14%, respectively. This suggests a potential link between overall health and the ability to maintain musical function during recovery.

These findings have practical implications for oncology care teams. As the authors noted, understanding how treatment affects musicians can help clinicians better counsel patients, answer questions about the potential impact on musicality, and provide realistic timelines for symptom resolution. This is particularly important given that more than half of those who experienced musical toxicity—57%—reported that their issues remained unresolved at the time of the survey.

While the study offers valuable insights, it is not without limitations. The median time from diagnosis to survey completion was 5.3 years, introducing the possibility of recall bias. Additionally, changes in musical ability may also stem from factors unrelated to cancer treatment, such as lack of practice, injuries, or natural aging—variables that were not accounted for in the analysis. The survey also did not include items specifically targeting neurocognitive function, even though some respondents mentioned difficulties with processing music or sight reading in open-ended responses.

Despite these limitations, the research highlights an important and previously underexplored aspect of survivorship. For musicians, the ability to perform is not just a skill but a source of identity, joy, and connection. Understanding how cancer treatment may disrupt this capacity allows for more personalized and compassionate care. It also underscores the need for future studies to explore interventions that might mitigate these effects, such as physical therapy, occupational therapy, or targeted rehabilitation for musicians.

As survivorship becomes an increasingly important part of cancer care, studies like this remind us that recovery is not solely about eliminating disease. It is also about preserving the activities and passions that make life meaningful. For the musicians affected by breast cancer treatment, acknowledging and addressing acute musical toxicity is a step toward holistic healing.
