Dolph Lundgren cancer misdiagnosis details have drawn renewed attention after the actor revealed more about his nearly decade-long cancer battle in his new memoir, Fights Worth Fighting: Finding Strength in Struggle. Lundgren was first diagnosed with kidney cancer in 2015. Years later, after his cancer progressed and treatment failed to produce the expected results, a UCLA specialist reviewed his case and discovered that the cancer had been misdiagnosed. The new assessment identified lung cancer with an ALK mutation and opened the door to a different treatment that dramatically changed his prognosis.
Lundgren, now 68, has spoken openly about the difficult period in recent interviews. He has described receiving a prognosis of only two or three years at one stage of his illness. He also revealed that the emotional strain became so severe that he discussed medical aid in dying with his brother.
That situation changed after he met UCLA oncologist Dr. Alexandra Drakaki in 2022. Her review of his medical records and tumor samples led to the revised diagnosis and a new treatment plan.
Lundgren later announced that he was cancer-free. His latest memoir provides additional details about the diagnosis, treatment, fear and uncertainty that shaped that period of his life.
When Was Dolph Lundgren First Diagnosed With Cancer?
Lundgren’s cancer journey began in 2015.
While he was in Sweden, the actor noticed blood in his urine. He initially thought the problem could have resulted from his martial arts training because he had previously experienced injuries around his kidneys.
Doctors performed medical imaging and discovered a tumor on one of his kidneys.
Further testing showed that the tumor was cancerous.
Lundgren underwent surgery to remove the tumor. After the operation, doctors monitored him through follow-up examinations.
For several years, the situation appeared manageable.
Lundgren continued working in the entertainment industry and did not publicly discuss the full extent of his health situation.
He later revealed that he kept the diagnosis private for years.
That secrecy meant most fans had no idea that the actor was dealing with cancer while continuing his film career.
What Happened When the Cancer Returned?
The situation changed in 2020.
Doctors discovered additional tumors, indicating that the cancer had returned and spread.
Lundgren has described tumors appearing in several areas, including his abdomen, liver, lungs and spine.
His doctors performed additional procedures and began systemic cancer treatment.
The situation became increasingly difficult.
The actor continued working, but the treatment affected his physical condition. He experienced significant side effects and lost weight during parts of the treatment.
At one point, doctors determined that one of his tumors was too large to remove surgically.
That development made his prognosis much more concerning.
Lundgren eventually received an estimate that he might have only two or three years left to live.
The news forced him to confront the possibility that his cancer could eventually become fatal.
Why the Original Diagnosis Became a Problem
The central issue in Lundgren’s medical story involved the classification of his cancer.
His doctors had initially treated him for kidney cancer after the discovery of the original kidney tumor.
However, when Lundgren later sought another opinion, Dr. Alexandra Drakaki reviewed his medical history and tumor samples.
Additional testing revealed an ALK mutation associated with lung cancer.
That finding changed the understanding of his disease.
It also meant that a different type of targeted treatment could be considered.
Lundgren has described the earlier diagnosis as a misdiagnosis because his cancer had been treated as kidney cancer when the later testing identified a lung-cancer-related molecular characteristic.
The distinction is important.
His story was not simply about a tumor appearing in the wrong location. It involved pathology and molecular testing that ultimately changed how doctors understood the cancer and which treatment they selected.
How Dr. Alexandra Drakaki Changed Lundgren’s Treatment
Drakaki became involved in Lundgren’s care after he sought another medical opinion.
She reviewed his previous medical information and ordered additional testing.
The results identified the ALK mutation.
That discovery provided a new treatment opportunity.
Instead of continuing with the previous approach, Lundgren began a targeted treatment designed to act against the specific molecular alteration found in his cancer.
The response was dramatic.
Lundgren has said that he began feeling better after changing treatment.
The tumors started shrinking.
The change also altered the outlook that he had previously received from doctors.
Instead of continuing toward the terminal prognosis he had been given, Lundgren now had a treatment that was producing a strong response.
He has repeatedly credited Drakaki with changing the course of his illness.
What Is an ALK Mutation?
ALK is a gene that can become altered in certain cancers.
An ALK rearrangement or mutation can cause abnormal signals that encourage cancer cells to grow.
In some lung cancers, doctors can test tumor tissue for ALK alterations.
When an ALK alteration is present, certain targeted medicines may be appropriate.
These drugs work differently from traditional chemotherapy.
They target specific molecular pathways involved in the growth of cancer cells.
Lundgren’s case became significant because additional testing identified an ALK-related characteristic that changed his treatment options.
The new treatment produced a strong response.
His experience demonstrates why molecular testing can play an important role in modern cancer care, particularly when a disease does not respond as expected.
How Much Did Lundgren’s Tumors Shrink?
Lundgren has described a substantial response after beginning the new treatment.
In earlier accounts of his recovery, he said the tumors began shrinking significantly within months.
He eventually reached a point where the cancer was no longer detectable.
The response represented a major change from the situation he had faced before receiving the second opinion.
Doctors had previously believed that his disease was progressing despite treatment.
The revised diagnosis led to a medication that targeted the cancer’s specific molecular characteristics.
Lundgren has described the result as life-changing.
His eventual recovery also allowed him to continue working and spend more time with his family.
Why Lundgren Sought Another Medical Opinion
The second opinion became important after Lundgren’s original treatment failed to control the disease as expected.
His condition continued to worsen.
The actor wanted another assessment of his diagnosis and available treatment options.
That decision led him to Drakaki at UCLA.
She did not simply rely on the existing diagnosis.
Instead, she reviewed the available medical material and conducted additional testing.
The results revealed information that changed his treatment.
Lundgren has since spoken about the importance of seeking another opinion when treatment does not produce the expected result.
His own experience provides a clear example of how another specialist’s review can uncover information that changes the medical approach.
What Prognosis Did Dolph Lundgren Receive?
During the most difficult stage of his illness, Lundgren was told that he might have only two or three years to live.
That prognosis had a profound effect on him.
He had a young family and continued professional responsibilities.
He was also still working on movies.
The possibility of dying within a few years forced him to reconsider his future.
Lundgren has described that period as one of the darkest moments of his life.
He began thinking about what would happen if the disease continued progressing and treatment stopped working.
Those concerns eventually contributed to his decision to discuss medical aid in dying with his brother.
Lundgren Reveals He Considered Medical Aid in Dying
In his new memoir, Lundgren revealed that he discussed the possibility of medical aid in dying with his brother, Johan, during the worst period of his cancer treatment.
He was worried that the disease could eventually leave him too ill to make decisions for himself.
The discussion did not progress into an actual plan.
Lundgren has explained that the situation changed soon afterward when he met Drakaki and learned that his cancer had been misdiagnosed.
The new diagnosis and treatment gave him renewed hope.
His recent disclosure offers a clearer picture of how serious he believed his situation had become before receiving the second opinion.
It also shows how dramatically his outlook changed after doctors found a treatment that worked.
Why the New Diagnosis Was So Important
The revised diagnosis changed more than the name of Lundgren’s cancer.
It changed the available treatment strategy.
His earlier doctors had been treating the disease based on the kidney cancer diagnosis.
The discovery of the ALK mutation pointed toward a different therapeutic approach.
Lundgren’s response to that treatment was substantial.
The tumors began shrinking, and his physical condition improved.
That improvement changed his prognosis.
The actor went from believing that his life could be nearing its end to eventually reaching a point where doctors found no evidence of active disease.
When Did Dolph Lundgren Become Cancer-Free?
Lundgren announced in 2024 that he was cancer-free.
He shared the news after undergoing a final procedure in Los Angeles.
The procedure involved lung ablation to address remaining tumor tissue.
By that point, the treatment he had received had produced a major response.
Lundgren described himself as having no evidence of active cancer.
His announcement represented a dramatic change from the prognosis he had received only a few years earlier.
He had gone through surgery, systemic treatment, additional tumors and a difficult period of uncertainty.
The final treatment marked an important milestone in his recovery.
What Is Lung Ablation?
Lung ablation is a procedure that targets abnormal tissue in the lung.
Doctors can use energy to destroy targeted tissue while attempting to limit damage to surrounding areas.
Different ablation techniques can use heat, cold or other forms of energy.
The procedure can be used in selected cancer cases depending on the tumor’s location, size and the patient’s overall medical situation.
Lundgren underwent lung ablation after his cancer treatment had produced a strong response.
His public comments indicate that the procedure addressed remaining tumor tissue.
He subsequently announced that he was cancer-free.
Did Dolph Lundgren Have Kidney Cancer or Lung Cancer?
This question has generated confusion because Lundgren’s original diagnosis involved kidney cancer.
Doctors initially discovered a cancerous tumor in his kidney in 2015.
Later testing identified an ALK mutation associated with lung cancer.
Recent coverage describes the revised diagnosis as lung cancer.
Lundgren has also explained that the cancer cells from his original tumor carried a mutation commonly associated with lung cancer.
The important point is that the later molecular testing changed the medical classification and treatment strategy.
His public account consistently describes the original diagnosis as kidney cancer and the later diagnosis as lung cancer.
The new classification allowed doctors to use a treatment that targeted the ALK-related cancer biology.
Why the Misdiagnosis Was Not Discovered Immediately
Cancer diagnosis can involve multiple layers of testing.
Doctors examine the location of a tumor, its appearance under a microscope and, when appropriate, its molecular characteristics.
In Lundgren’s case, the original diagnosis remained in place for years.
Additional tumors appeared later.
The treatment response eventually raised more questions about whether doctors had correctly identified the disease.
The second opinion provided an opportunity to review the case with new information.
Drakaki’s testing identified the ALK mutation.
That discovery changed the treatment plan.
The case illustrates why cancer diagnosis can evolve when doctors obtain additional tissue information or perform more advanced molecular testing.
How the Cancer Battle Affected Lundgren Physically
Lundgren has described substantial physical effects during treatment.
He lost weight and experienced side effects from the medications he received.
His condition became visible to people around him even though he tried to continue working.
During interviews, he has explained that he was sometimes physically depleted while filming.
Despite the treatment, he continued accepting professional work.
His determination to continue working also helped him maintain a sense of normality.
However, the physical effects became difficult to hide as the disease progressed.
The improvement after the new treatment was therefore particularly meaningful.
He began feeling stronger as the tumors responded.
How Lundgren Kept His Cancer Private
Lundgren kept his cancer diagnosis largely private for years.
His family knew about the situation, but he did not immediately tell the public.
He continued appearing in movies while receiving treatment.
His professional credits during that period included projects such as Aquaman, Creed II and films in The Expendables series.
His decision to remain private allowed him to continue working without making his medical condition the central focus of his career.
He eventually decided to share the story publicly after the cancer became a major part of his life.
His revelations have since provided fans with a much clearer understanding of what happened behind the scenes.
The Role of Lundgren’s Family
Lundgren’s family remained an important source of support throughout the cancer battle.
His wife, Emma Krokdal, accompanied him to medical appointments and helped him through treatment.
His daughters also became part of his motivation to continue fighting the disease.
The actor has described the emotional burden of knowing that his family might lose him.
That fear became especially intense after doctors gave him the two- to three-year prognosis.
His later recovery allowed him to spend more time with his family than he once expected.
That experience has influenced how he now views his health and priorities.
How the Cancer Experience Changed His Perspective
Lundgren has said that surviving cancer changed his approach to life.
Before his diagnosis, he maintained an intense work schedule and demanding physical routine.
The illness forced him to reconsider how he spent his time.
He now speaks more openly about appreciating his family and everyday experiences.
His physical training has also changed.
He continues to exercise but has described taking a more measured approach.
The experience taught him that maintaining health involves more than physical strength.
It also requires regular medical attention and an openness to changing course when circumstances change.
Lundgren’s New Memoir Reveals More About His Health
His 2026 memoir, Fights Worth Fighting: Finding Strength in Struggle, provides the most recent account of his cancer experience.
The book describes his diagnosis, treatment and emotional struggles.
It also details the period when he considered medical aid in dying.
Lundgren explains that he had almost lost hope before meeting Drakaki.
The discovery of the ALK mutation became a turning point.
The memoir also explores the emotional aftermath of surviving a disease that he once believed would kill him.
For Lundgren, surviving the illness became another chapter in a life already defined by physical challenges and demanding professional work.
Lundgren’s Current Cancer Status
As of September 23, 2026, Lundgren continues to describe himself as cancer-free.
He first announced that status in 2024 following his final lung ablation.
There is no current public report of a new cancer recurrence.
His recent interviews have focused on the earlier diagnosis, the subsequent misdiagnosis and the treatment that changed his prognosis.
He has also spoken about the emotional consequences of surviving a serious illness.
The actor continues to work and discuss his experiences publicly.
His memoir has brought renewed attention to the medical journey that he kept private for many years.
