Doctors
Dr. Daniel Keizman is a medical oncologist and Head of the Urologic Oncology Unit at the Ichilov–Sourasky Medical Center in Tel Aviv, Israel.
His clinical work focuses primarily on cancers of the genitourinary system — particularly prostate cancer, kidney cancer, and bladder cancer.
Patients come for consultation at very different stages of the disease.
Some are facing a new diagnosis and are trying to understand what the next step should be.
Others seek a second opinion after treatment has already been recommended.
Dr. Keizman is also involved in clinical research in the field of urologic oncology, including studies exploring modern systemic treatments such as targeted therapy and immunotherapy.
This combination of clinical and research experience allows each case to be evaluated not only according to current treatment guidelines, but also in light of emerging therapies.
Clinical Focus
Genitourinary cancers include several different diseases. Although they affect the same anatomical system, their biology and progression can vary significantly.
During consultation, Dr. Keizman evaluates conditions such as:
- Prostate cancer
• Kidney cancer
• Bladder cancer
• Rare tumors of the urinary tract
Treatment decisions depend on multiple factors, including the stage of the disease, tumor biology, overall health, and previous treatments.
In some situations, treatment should begin promptly.
In others, careful monitoring may be the most appropriate approach.
Clinical Experience
Dr. Keizman specializes in the management of genitourinary cancers, particularly prostate, kidney, and bladder malignancies.
He consults with patients at different stages of the disease.
Some seek guidance after receiving a new diagnosis.
Others come for a second opinion when treatment options need to be reconsidered.
In addition to his work at the Ichilov Medical Center, Dr. Keizman provides private consultations at Tel Aviv Medical Clinic.
Medical Approach
One of the most complex questions in oncology is not only what treatment exists, but also when it should be used.
In some cases treatment needs to begin immediately.
In others, monitoring the disease for a period of time may be appropriate.
Sometimes the best strategy involves combining several treatment approaches.
For that reason, consultation is always based on a careful review of the patient’s medical data, including:
- imaging studies
• laboratory tests
• pathology reports
• the progression of the disease over time
Only after understanding the full clinical picture can treatment options be discussed.
Education and Medical Training
- Dr. Daniel Keizman received his medical degree from the Hebrew University of Jerusalem.
- He completed his specialization in medical oncology at the Sheba Medical Center (Tel HaShomer), where he worked with patients diagnosed with a wide range of oncologic conditions.
Over time, his clinical focus became centered on cancers of the genitourinary system, including prostate, kidney, and bladder malignancies.
Dr. Keizman also participates in clinical research exploring new treatment approaches for these diseases.

Frequently Asked Questions
1. I noticed blood in my urine or problems with urination. Could this be cancer?
Patients sometimes come to my clinic with exactly these symptoms, and naturally many of them are worried.
However, symptoms like these do not necessarily mean cancer. They may also be caused by inflammation, kidney stones, or benign prostate enlargement.
In situations like this, the first step is to carefully review the patient’s tests and imaging studies. Sometimes additional examinations are needed, but in many cases the explanation turns out to be less serious than people initially feared.
The most important thing is not to draw conclusions on your own, but to evaluate the situation properly with a physician.
2. My PSA level is elevated. Does this mean I have prostate cancer?
This is one of the most common questions I hear from patients.
An elevated PSA does not automatically mean prostate cancer. In many cases it may be related to inflammation of the prostate or benign enlargement.
When a patient comes with an elevated PSA, we look at more than just a single number. We evaluate the trend of the PSA level over time, imaging studies such as MRI, and the overall clinical context.
Sometimes the evaluation shows there is no cancer. In other situations, further testing may be necessary.
3. I’m afraid to see an oncologist. What usually happens during the first consultation?
This fear is very understandable.
Many patients tell me during the first meeting: “Doctor, I’m afraid to even hear the diagnosis.”
The first consultation is usually focused on understanding the situation. We review the patient’s medical history, test results, and imaging studies together.
Sometimes the situation is less alarming than the patient expected. And even when cancer is confirmed, there are often several treatment options to consider.
The goal is to explain these possibilities calmly and clearly.
4. I have already been diagnosed with prostate cancer. What treatment options exist?
One important thing I always explain is that the same diagnosis can be treated in different ways.
Some forms of prostate cancer grow very slowly. In those cases, active surveillance may be the most appropriate approach.
In other situations, surgery, radiation therapy, or systemic treatment may be recommended.
Modern therapies may include hormonal therapy, targeted treatment, or other medical approaches.
The right decision depends on many individual factors, which is why treatment choices should never be made without a proper medical evaluation.
5. Are there new treatment options for kidney or bladder cancer?
Yes, oncology has changed significantly in recent years.
New medications — including immunotherapy and targeted therapies — have expanded the range of treatment possibilities for many patients.
In addition, clinical trials are constantly exploring new therapeutic approaches. Participation in such studies may sometimes provide access to innovative treatments.
Even in complex situations, it is important to review all possible options.
6. If cancer has already been diagnosed, is there still hope for effective treatment?
This is probably the question patients ask most often.
The answer depends on many factors, including the stage of the disease and the biology of the tumor. However, treatment outcomes in oncology today are significantly better than they were even 10–15 years ago.
Many patients can be successfully treated. In other cases the disease can be controlled for many years.
New treatments and clinical research continue to expand the options available. That is why it is always important to discuss the situation with a specialist before drawing conclusions.
