South Korean actor Choi Sung Won, widely recognized for his memorable role as Sung No Eul in the acclaimed tvN drama Reply 1988, has captivated audiences and evoked profound empathy by openly sharing the arduous details of his two battles with acute leukemia. His emotional journey, marked by periods of immense suffering and unwavering determination, was candidly revealed during a recent appearance on KBS 2TV’s Happy Together – Glad I’m Not Alone, a program designed to highlight inspiring personal narratives. The actor’s revelations shed light on the physical and psychological toll of a life-threatening illness, as well as the indomitable spirit required to overcome such formidable challenges, particularly within the demanding landscape of the entertainment industry. His story not only celebrated his personal triumph over disease but also underscored the deep-seated passion that ultimately guided him back to his chosen craft, culminating in the joyous announcement of his full recovery, which garnered widespread applause and an outpouring of support from fans and colleagues alike.
The Ascent and Impact of Reply 1988
Choi Sung Won’s career trajectory saw a significant upswing with his role in Reply 1988, which aired from 2015 to 2016. Before this breakthrough, Choi had built a steady, if less prominent, career in musical theatre and television. He debuted in the musical "Finding Kim Jong Wook" in 2007 and gradually made a name for himself with his versatile acting. However, it was his portrayal of Sung No Eul, the younger brother of the protagonist Sung Deok Sun, that catapulted him into national recognition. Reply 1988 itself was a cultural phenomenon, lauded for its nostalgic depiction of family life, friendship, and first loves in a Seoul neighborhood during the late 1980s. The drama achieved immense critical and commercial success, becoming one of the highest-rated dramas in cable television history and earning numerous awards. Its ensemble cast, including Choi Sung Won, garnered widespread affection, with No Eul’s character, despite being a supporting role, resonating with viewers for his earnestness and unique personality. This period marked a crucial turning point for Choi, as he was poised for a promising future in the Korean entertainment industry, with new opportunities and a broader fanbase eagerly anticipating his next projects.
A Chronology of Courage: Two Battles with Leukemia
The promising trajectory of Choi Sung Won’s career was abruptly interrupted by a series of unforeseen health crises. The timeline of his battles with acute leukemia paints a picture of resilience in the face of repeated adversity:
First Diagnosis and Hiatus (2016)
Shortly after the conclusion of Reply 1988, at a time when his popularity was at its peak, Choi Sung Won received the devastating diagnosis of acute leukemia in May 2016. Acute leukemia is a fast-progressing cancer of the blood and bone marrow, characterized by the rapid production of abnormal white blood cells that interfere with the bone marrow’s ability to produce healthy blood cells. The news sent shockwaves through his burgeoning career, forcing him to immediately halt all activities, including withdrawing from the then-airing JTBC drama Mirror of the Witch, where he had taken on a significant role. This abrupt cessation of work was not merely a career setback but a life-or-death situation, demanding his full attention and energy for intensive medical treatment. He underwent rigorous chemotherapy, a standard treatment protocol for acute leukemia aimed at destroying cancerous cells. The initial public reaction was one of shock and profound concern, with fans and industry colleagues expressing their unwavering support and hopes for his swift recovery.
First Recovery and Resumption of Activities (Late 2017 – Early 2019)
Following a challenging period of treatment and recovery, Choi Sung Won bravely announced in late 2017 that his health had significantly improved, marking his return to the entertainment scene. His determination to resume acting was evident as he gradually began taking on new projects, albeit at a more measured pace. He appeared in dramas such as My Strange Hero (2018-2019) and various theatrical productions, signaling his triumphant return to the craft he loved. This period was a testament to his fighting spirit and the medical team’s efforts, offering a beacon of hope to those battling similar illnesses. His return was met with enthusiasm and relief from his fanbase, who admired his tenacity.
The Devastating Relapse (Mid-2019)
Tragically, just two years after his initial recovery and successful return to work, Choi Sung Won faced another crushing blow: a relapse of his acute leukemia in mid-2019. This recurrence plunged him back into the harrowing cycle of illness and treatment. On Happy Together, he articulated the profound emotional and existential crisis that accompanied this second diagnosis. "After overcoming it once and then getting sick again, I wondered, ‘Is acting really my path? Is it trying to kill me?’" he confessed, revealing the deep despair and self-doubt that plagued him. The physical suffering was equally immense, as he recounted, "It was extremely painful to the point I couldn’t even stand properly." This second battle was arguably more challenging, not only physically but also mentally, as it tested his resolve and forced him to confront the fragility of life and career. He was once again forced into an indefinite hiatus, retreating from public life to focus entirely on his health.
Second Recovery and Unwavering Artistic Passion (2020 – 2026)
Despite the overwhelming pain and emotional torment, Choi Sung Won’s intrinsic passion for acting never waned. During his second period of intense treatment and recovery, he revealed a remarkable dedication to his craft. "Even while in excruciating pain, I was analyzing the expressions of the people fighting in the hospital," he shared on the program. It was during these darkest moments that he experienced an epiphany: "It was then I realized, ‘I have to act.’" This profound realization underscored the depth of his artistic calling, transcending physical suffering. MC Jang Hang Jun, visibly moved by Choi’s confession, expressed awe, saying, "When your body is struggling, you don’t think about work. That’s impressive." This testament to his unyielding spirit highlights a rare dedication.
Most notably, Choi Sung Won shared the heartening news on the program: "I’ve been declared fully recovered," earning rounds of heartfelt applause from the hosts and studio audience. This declaration marks the culmination of years of arduous struggle, signifying a definitive victory over a formidable disease. His journey through two relapses and subsequent recoveries stands as a powerful narrative of human endurance and the transformative power of passion.
Medical Context: Understanding Acute Leukemia and Relapse
Acute leukemia is a severe and rapidly progressing cancer that originates in the blood-forming cells of the bone marrow. It is characterized by the uncontrolled proliferation of immature white blood cells (blasts), which crowd out healthy blood cells, leading to symptoms like fatigue, infections, and bleeding. The two main types are Acute Myeloid Leukemia (AML) and Acute Lymphoblastic Leukemia (ALL), both requiring immediate and aggressive treatment.
Treatment for acute leukemia typically involves intensive chemotherapy, which aims to destroy the cancerous cells. In many cases, especially for relapsed or high-risk patients, a stem cell transplant (also known as a bone marrow transplant) may be necessary. This procedure involves replacing diseased bone marrow with healthy stem cells, often from a donor. The challenges of treatment are immense, involving severe side effects from chemotherapy, including immunosuppression, nausea, fatigue, and hair loss. Recovery is a long and arduous process, often requiring extensive rehabilitation.
A relapse, as experienced by Choi Sung Won, is a devastating complication where the cancer returns after a period of remission. Relapse can occur months or years after initial treatment and often requires more aggressive and complex therapeutic approaches. The prognosis after a relapse can be more challenging, making each subsequent recovery a more significant medical achievement. Choi Sung Won’s double recovery from acute leukemia, particularly after a relapse, speaks volumes about the advancements in modern medicine and, crucially, his own remarkable biological resilience and mental fortitude. Statistics show that while initial remission rates for acute leukemia can be high, long-term survival rates, especially after relapse, vary significantly depending on the type of leukemia, patient age, and other factors. His story therefore serves as a testament to perseverance against formidable odds.
