Santo Domingo.- Dr. Idalid Ivy Franco, a radiation oncology specialist at Mass General Brigham, explained that radiotherapy is one of the most effective and precise treatments against cancer, thanks to technological advances that allow attacking tumors with greater accuracy and fewer side effects.
Franco pointed out that this treatment uses high-energy X-rays to damage the DNA of cancer cells, preventing their growth and promoting their elimination, while healthy cells can recover.You may be interested in: Mass General explains differences between targeted therapy and immunotherapy for cancer
The specialist highlighted that radiotherapy does not cause pain during its application and is frequently used in cancers of the lung, prostate, breast, gynecological and brain tumors. He indicated that the new techniques allow for better focusing of radiation, reducing the impact on healthy tissues and minimizing adverse effects.Difference between radiotherapy and chemotherapy
Franco explained that chemotherapy is a systemic treatment that circulates throughout the body, while radiotherapy acts locally, similar to surgery. In that sense, he specified that hair loss only occurs in the treated area, unlike chemotherapy, which can produce widespread loss.Most common side effects
Among the most frequent side effects, the doctor highlights tiredness or mild fatigue, skin redness similar to a sunburn, and a more frequent need to go to the bathroom (depending on the treated area). He clarified that these symptoms are usually manageable and that most patients maintain a good quality of life during treatment.Impact on Daily Life
The doctor recommended that patients stay active, hydrated, and maintain healthy habits, as this helps reduce fatigue. She pointed out that many can continue working, although some choose to reduce their hours or work from home in the final weeks of treatment. He explained that fatigue occurs because the radiation acts at the cellular level, temporarily affecting the normal functioning of the organism, but improves at the end of the therapy.Emotional and family support
Franco emphasized that initial fear is common due to lack of knowledge about the treatment. Therefore, he recommends talking with the doctor and radiation oncologist to clarify doubts and make informed decisions. He also highlighted the key role of family and caregivers, who can accompany the patient to consultations, help with the information received, and provide support during the process. The specialist emphasized that radiotherapy has evolved significantly and allows many patients, even with advanced diagnoses, to live longer and with a better quality of life.Professional Career
Dr. Franco obtained her medical degree from Harvard Medical School and a Master's in Public Health from Harvard T.H. Chan School of Public Health. She subsequently completed her residency in radiation oncology at the Harvard Radiation Oncology Program. Her clinical practice focuses on gynecological cancers, with specialization in brachytherapy. Her research addresses oncological outcomes in vulnerable populations, the impact of social determinants of health on racial and ethnic disparities, and cost-effectiveness in medical care. She is currently an Assistant Professor of Radiation Oncology at Harvard Medical School and Director of Engagement and Enrichment for the Department of Radiation Oncology at Brigham and Women's Hospital, institutions affiliated with Mass General Brigham.
