In Which Age Group Is Testicular Cancer Most Commonly Seen and What Are the First Symptoms?
When people hear the word cancer, they generally think of diseases that occur in middle-aged and older individuals. However, unlike this common perception, testicular cancer is a unique type of tumor that primarily affects young adults. Most commonly encountered in young men between the ages of fifteen and forty-four, this disease is one of the areas in medicine with the most encouraging outcomes when detected early. Thanks to modern treatment methods, advanced drug protocols, and surgical techniques, nearly all patients diagnosed at an early stage before the disease has spread throughout the body can achieve complete recovery. Of course, recognizing the symptoms in time and consulting a specialist promptly without giving in to fear is the key factor in this process. Many young men may overlook minor changes in their bodies amid the rush of daily life or interpret them as simple injuries. However, performing regular self-examinations while bathing provides a life-saving opportunity for early diagnosis.
The main symptoms that should be noted include:
- Painless swelling
- A firm palpable mass
- Noticeable asymmetry of the scrotum
- Dull pain in the groin
- A feeling of heaviness in the testicle
- Sudden fluid accumulation in the scrotum
How Does a History of Undescended Testicle Affect the Development of Testicular Cancer?
Although many factors such as nutrition, environmental influences, and lifestyle have been investigated in the development of testicular cancer, the risk factor most emphasized by the medical community and supported by the strongest genetic evidence is an undescended testicle. During fetal development, the testicles of male babies initially begin to form deep within the abdominal cavity, very close to the kidneys. As pregnancy progresses, especially near birth, these organs gradually descend through the inguinal canal and settle into the scrotum. This descent has a vital biological purpose. The internal temperature of the human body is warmer than what is required for healthy testicular function and preservation of cellular structure. The scrotum provides a cooler environment than body temperature, thereby protecting the organ. Sometimes this descent does not occur normally, and the testicle may remain trapped within the abdomen or the inguinal canal.
Individuals who have experienced this anatomical condition in the past have a significantly higher likelihood of developing cancer later in life compared with the general population. In fact, the higher the testicle remains within the body, the greater the risk becomes. The strength of this anatomical relationship is clearly demonstrated when the medical histories of patients who develop tumors in both testicles are examined. Therefore, individuals who were monitored or treated for an undescended testicle during childhood are advised to remain much more vigilant as they grow older.
How Is the Diagnostic Process Managed in Patients with Suspected Testicular Cancer?
In a person who notices unusual hardness, deformity, or swelling in the testicle and visits a healthcare facility, the diagnostic process progresses systematically, rapidly, and without placing unnecessary burden on the patient. Following a detailed physical examination, the first step involves high-resolution imaging technologies. Scrotal ultrasonography, which operates using sound waves and involves no radiation, provides a very clear view of the internal structure of the testicular tissue. With this method, it is possible to distinguish to a great extent whether a mass is a harmless fluid-filled cyst or a solid structure composed of cellular tissue.
Alongside imaging studies, certain specialized blood tests that provide information at the molecular level of the disease are also performed. These specialized proteins or enzymes, known as tumor markers, may be produced by cancer cells and released into the bloodstream. Measuring the blood levels of these markers provides physicians with a valuable roadmap both for predicting the subtype of the disease and for monitoring the effectiveness of the treatment to be applied.
The main diagnostic methods include:
- Detailed physical examination
- Scrotal ultrasonography
- Alpha-fetoprotein blood test
- Beta-hCG blood test
- Lactate dehydrogenase blood test
- Computed tomography
Why Is a Needle Biopsy Never Performed for a Suspected Testicular Cancer Mass?
In many different organ cancers, such as thyroid, prostate, or breast cancer, obtaining a small tissue sample from a suspicious mass with a needle and examining it under a microscope is a standard diagnostic approach. However, when it comes to the testicle, performing a biopsy is a procedure that should absolutely be avoided due to oncological safety principles. The main reason is the unique and closed lymphatic connections of the testicle within the body.
Because the testicle completes its development in the abdominal cavity during fetal life and descends afterward, its lymphatic vessels extend directly to the deepest regions around the kidneys. In contrast, the lymphatic pathways of the scrotal skin surrounding the testicle drain to an entirely different route, namely the superficial inguinal region. If a needle is inserted through the scrotal skin into a suspicious tumor, tumor cells may leak along the needle tract. As a result, a disease that would normally tend to spread only to the deep abdominal lymph nodes may unexpectedly spread to the inguinal lymph nodes and beneath the skin. In short, a well-intentioned biopsy may completely alter the disease’s pattern of spread and make treatment far more complicated. Therefore, the first step in diagnosis and treatment is always the surgical removal of the organ as a whole.
How Is Orchiectomy, the First Step in Testicular Cancer Treatment, Performed?
The most distinctive feature of this surgical intervention, which establishes the definitive diagnosis while also serving as the first treatment step, is that it is performed not through the scrotum but through an incision made in the patient’s groin. Through this controlled inguinal incision, the surgeon reaches the inguinal canal directly and secures the main blood vessels and spermatic cord connecting the testicle to the body at their highest possible level.
The primary objective is to prevent potential cancer cells from entering the bloodstream or lymphatic circulation during manipulation of the testicle. Once the vessels have been securely ligated, the testicle is carefully withdrawn upward from its position and removed from the body intact. The removed tissue is then sent to the pathology laboratory for detailed examination to determine the cellular characteristics and aggressiveness of the disease. Losing an organ at a young age may understandably create aesthetic and psychological concerns for patients. To address this legitimate concern, medical silicone prostheses that closely match the weight and size of the removed testicle can, upon request, be placed into the scrotum during the same operation.
Is It Necessary to Remove the Entire Organ in Every Case of Testicular Cancer?
In the traditional oncological approach, complete removal of the testicle has long been considered the only accepted standard for testicular cancer. However, thanks to advances in medical practice and opportunities for early diagnosis, organ-preserving surgical options can now be successfully performed when appropriate conditions are met. Particularly in individuals who were born with only one testicle, have previously had the other testicle removed, or, although extremely rare, have tumors in both testicles simultaneously, sacrificing the entire organ results in lifelong dependence on hormone replacement therapy and irreversible infertility. Testosterone is essential not only for sexual function but also for bone density, muscle mass, psychological well-being, and overall energy levels.
With the sensitivity of modern ultrasound devices, very small masses that cannot even be detected during physical examination can now be identified at an early stage. Large scientific studies have shown that a considerable proportion of these very small masses are not cancerous but may instead be benign lesions. Therefore, certain specific criteria are required to protect patients from unnecessary organ loss.
The criteria considered for organ-preserving surgery include:
- Tumor size smaller than two centimeters
- A mass occupying only a small portion of the total testicular volume
- Normal blood tumor marker levels
- The patient having only one testicle
- Simultaneous lesions in both testicles
Why Is Intraoperative Pathological Examination Critical in Testis-Sparing Surgery for Testicular Cancer?
In operations where only the tumor tissue is removed and the remaining portion of the testicle is preserved, the greatest risk physicians face is leaving behind invisible cancer cells. To eliminate this risk, a highly specialized pathology technique known as a frozen section examination is used during surgery. While the operation is in progress, the suspicious tissue is removed with great precision and rapidly sent to the laboratory. As the surgeon waits in the operating room, the pathologist freezes the tissue at subzero temperatures using special equipment and examines it under the microscope within minutes.
The course of the operation is determined immediately according to the urgent pathology report. If no disease cells are found at the margins of the removed tissue, the procedure is safely completed as planned and the testicle is preserved. However, if the remaining tissue is found to be at risk and the surgical margins are not oncologically adequate, the surgical team immediately proceeds with complete removal of the testicle to avoid compromising the patient’s health. This simultaneous and dynamic approach provides a powerful safety net that eliminates the possibility of incomplete treatment.
Where Do Testicular Cancer Cells Spread Through the Lymphatic System?
The spread of testicular cancer throughout the body generally does not follow an irregular or random course; on the contrary, it follows an extremely predictable anatomical pathway. As previously mentioned, the organ completes its embryological development near the kidneys before descending into the scrotum. This embryological origin causes the main lymphatic vessels of the testicles to extend directly to the deepest part of the abdominal cavity, around the major blood vessels in front of the spine. This region, referred to in medicine as the retroperitoneal space, represents the first major station that testicular tumors attempt to reach within the body.
Located deep behind the intestines along the posterior abdominal wall, these lymph nodes surround vital structures such as the aorta, the main artery leaving the heart, and the vena cava, the body’s largest vein. When cancer cells enter the lymphatic system from the testicle, they reach this deep region and begin to establish themselves there. Correctly determining the stage of the disease and planning the treatment strategy require focused attention on this region.
What Is Retroperitoneal Lymph Node Dissection Performed to Prevent the Spread of Testicular Cancer?
The surgical removal of the lymph nodes located in the deepest part of the abdominal cavity is known as retroperitoneal lymph node dissection. Particularly in certain subtypes of testicular cancer, if the disease has not spread to distant organs through the bloodstream and remains confined to these regional lymph nodes, this major operation is a highly effective method for eradicating the disease from the body.
During this procedure, all suspicious lymphatic tissues within a wide and delicate anatomical area extending from the level of the renal vessels to the vascular bifurcations in the lower abdomen are carefully removed. This extensive dissection not only eliminates the existing cancer burden but also definitively determines the disease’s cellular stage. These removed lymph node packets are thoroughly examined by pathology, allowing physicians to determine with a high degree of certainty whether the patient will require additional adjuvant medical treatment after surgery.
How Are the Reproductive Functions of Young Patients Preserved During Testicular Cancer Lymph Node Surgery?
The greatest and most distressing side effect of these extensive intra-abdominal lymph node surgeries in previous decades was damage to the extremely delicate nerve networks located in this region. These nerves do not control muscle movement but rather are specialized autonomic structures responsible for ejaculation in men. When these nerves were injured during conventional surgery while focusing on removing the cancer, patients could continue to have normal sexual intercourse and experience orgasm, but semen would flow backward into the bladder instead of exiting the body. For young patients in their twenties preparing for marriage or wishing to have children, this became a particularly devastating experience.
Fortunately, with the nerve-sparing surgical techniques adopted in modern medical practice, this risk has been significantly reduced. During surgery, surgeons adhere strictly to specific anatomical templates and boundaries. While removing lymph nodes that may contain cancer, these delicate nerve fibers are identified with millimetric precision using surgical magnification or robotic camera systems and are carefully preserved. Thanks to this meticulous technique, not only is the disease removed from the body, but normal sexual function is also largely preserved.
The delicate structures carefully protected during surgery include:
- Sympathetic nerve chains
- Hypogastric plexus
- Postganglionic nerve fibers
- Regional lumbar vessels
What Are the Challenges of Open Lymph Node Surgery for Testicular Cancer?
Reaching the deep valley behind the abdominal wall where the major blood vessels are located is anatomically very challenging for surgeons. In the traditional open surgical approach, accessing this deep region requires a long incision extending from just below the rib cage to the groin, opening the abdomen from top to bottom. Opening such a large area and keeping the intestines retracted for an extended period increases the physiological stress placed on the body during surgery.
This long and deep incision naturally delays the patient’s recovery and ability to stand and walk after surgery. Returning to normal daily life, social activities, and work may take several weeks with conventional methods. In addition, the large incision presents a demanding postoperative period in terms of wound care and pain management.
The main disadvantages of conventional open surgery include:
- Prolonged hospital stay
- Significant postoperative pain
- Postoperative bowel sluggishness
- A surgical scar that takes time to heal
- Delayed return to daily life
- The need for breathing exercises
What Advantages Does Robotic Surgery Technology Provide in Testicular Cancer Operations?
Robotic surgery systems, one of the greatest gifts technology has brought to medicine, have completely transformed the course of these challenging and deep lymph node operations. Instead of making a large incision across the abdomen, the surgery is performed through slender robotic arms inserted through small port openings in the abdominal wall, each measuring no more than one or two centimeters. The surgeon controls these arms with exceptional precision and focus while seated at a dedicated console beside the patient.
The system’s high-resolution three-dimensional camera, capable of magnifying tissues up to ten times, allows ejaculation nerves and tiny blood vessels that are nearly impossible to identify with the naked eye to be seen clearly. The robotic arms’ ability to rotate beyond the anatomical limits of the human wrist, together with their capacity to eliminate natural hand tremors, enables lymphatic tissues closely attached to major blood vessels to be dissected with great safety. Because there is no large surgical incision, patients are generally able to stand, leave the hospital within a few days, and return to their active lives much sooner.
The main comfort advantages of robotic surgery for patients include:
- Small, cosmetically favorable incisions
- Much less blood loss
- Rapid recovery
- Reduced need for pain medication
- Better preservation of nerves
- Faster return to work
What Surgical Approach Is Used for Chemotherapy-Resistant Testicular Cancer Masses?
In advanced stages where testicular cancer has spread systemically, patients are first treated with powerful drug therapies, namely chemotherapy regimens. Chemotherapy becomes a highly effective weapon for identifying and destroying rapidly dividing tumor cells throughout the body. In many patients, blood marker levels return completely to normal after this treatment. However, in some cases, the masses in the retroperitoneal lymph nodes resist these drugs and do not shrink. The main reason is the presence of a different tissue type called teratoma, which is structurally resistant to chemotherapy.
Teratomas generally grow slowly, but over time they may gradually adhere to and integrate with vital organs, the aorta, and the kidneys. Leaving these masses inside the body is highly dangerous because they may continue to enlarge over the years, impair organ function, or transform back into aggressive cancer cells. Removing these masses from the major blood vessels in tissue altered by chemotherapy and hardened almost like cement represents one of the greatest technical challenges in surgery. Sometimes the mass surrounds the vessel so extensively that cooperation with cardiovascular surgeons becomes necessary to remove part of the vessel and replace it with a vascular graft.
Why Is a Multidisciplinary Specialist Team Needed in the Management of Testicular Cancer?
By its very nature, cancer management is far too complex and detailed to fit within the expertise of a single physician or a single medical specialty. Every stage of the disease varies according to the microscopic characteristics of the tumor, the patient’s blood test results, imaging findings, and overall health status. Therefore, in advanced referral centers, patient cases are discussed collectively in multidisciplinary tumor boards where physicians from different specialties evaluate each case together.
While urologists plan the surgical options, medical oncologists determine the timing of systemic drug therapies. When necessary, radiation oncologists design targeted radiotherapy treatments. Pathologists analyze the genetic and cellular characteristics of the diseased tissue, while radiologists and nuclear medicine specialists identify even the smallest risks of spread. Any side effects that may arise throughout the treatment journey are addressed through the combined experience of this multidisciplinary team. This fully integrated system provides the greatest assurance for helping the patient recover from the disease and return to a healthy life.
The main departments involved in the successful management of the process include:
- Urology
- Medical oncology
- Pathology
- Radiology
- Radiation oncology
- Nuclear medicine
