I am grateful to all the ICS nurses and Dr Ooi for the care throughout my chemo journey. It was the worst 5 months of my life because of the cancer but ICS made it better...First thank you for Dr Ooi for being there throughout the journey esp when I had a fever for almost one month due to Taxol induced Pneumonitis, and for the timely intervention to send me for the necessary heart checks, CT scan, etc, to get to the root of the problem and changing me from Paclitaxel to Abraxane. He did not waste a single day to troubleshoot the problem.I also want to thank the nurses who attended to me. Special mention to Kartini who is very gentle and is incredibly skilled in putting in the IV plug and drawing my blood. Seriously if she poke you its as unpainful as it gets already. I also want to thank Alina and Pushpa for diluting my meds and administering them without hiccups too. I hear stories of chemo leaking into tissues but I never had such experience at ICS because the nurses are very experienced. Plus the part-time nurse (so sorry I forgot your name but remember your warm words) for always making sure I'm comfortable with blankets drinks and such. And Susie for the warm greeting every time I come in.Only issue I have is because they are sooo popular and due to covid measures only 4 patients allowed at one time (I think) so scheduling is a headache. The nurses (esp Alina) try their best to schedule everyone. :)And BTW you can watch Netflix and Viu in the clinic (if the TV is available that day) if you have your own account because they have smart TV. This is very important when you are in discomfort during chemo, any distraction helps. The air is very clean because they have air purifiers in every room. Here are some pics. Cheers.

I'm really grateful to Dr Ooi Wei Seong and the staff of ICS for making my weeks at ICS so bearable. They're an excellent team of healthcare professionals who really care for their patients. During my treatment sessions, they always made sure I was comfortable and checked on me frequently.Dr Ooi is an experienced professional who's deeply knowledgeable in his field, but he also has a very warm, approachable and jovial manner that puts one at ease. All of the clinic staff - the nurses (Pearl, Alena, Pushpa, Kartini and Nerina), the clinic administrator (Susie) and the lady who gives me barley water every week - are a warm and wonderful team and never fail to make me smile during every visit.Thank you to the team at ICS for your compassion and support during this challenging time.
I consider myself lucky to be treated by this medical team. Dr Ooi, as always, has been very friendly and patient. He will try his best to give advice to me, other than providing medication, to make me feel better especially during my chemo treatments. The girls are helpful and caring, making sure I am comfortable during the treatments. At times they do brightens up my day considering this is my lowest point of my life. Thank you all of you. I will miss you all.

From Day One, Dr Ooi has put me at ease. With his positive and cheerful behaviour. When my tumours returned shortly after surgery, he was still edging me not to give up. Best of all, he was responsive even if you have concerns outside his clinic hours and wanted to talk to him about it.Thank you for making me feel like I was getting the best care. Thank you to all the nurses (past and present- Hangqi, Pearl, Alìna, Kartini, Pushpa) for making me feel safe, as pain free as possible and cared for. I know I haven’t been an easy patient when the needles come out. But the nurses & staff were extremely patient. Thanks to Susie as well.Great job to all!

We Make A Difference Together

We never forget that we are caring for a patient, not just fighting cancer. Every patient has his or her fears, worries, and concerns such as treatment costs and outcomes after being diagnosed with cancer. At International Cancer Specialists (ICS), we understand that these stresses can make an already traumatic experience even worse. This is why we take the time and effort to understand and offer solutions where we can, based on our experience caring for thousands of patients from Singapore and over 20 countries around the world.

We believe that every patient is an individual and no two are the same. Therefore, every patient who visits our centre deserves to be treated with a unique approach that will result in the best possible results. At ICS, we remember your name. For we see you as a person first, not just a statistic.

Cancer Specialist and Research.

One of our greatest strengths is our ability to translate today’s most promising research findings into tomorrow’s new, more effective treatments with fewer side effects. In other words, more targeted and personalised treatments as no two cancers are the same. Our patients benefit from that quest by receiving not only sound advice upon their diagnosis but also the best treatments to minimise or eliminate their cancer to attain a high quality of life before, during and after treatment.

Why Choose Us

Every patient is a human-being first and foremost.

It’s never easy to journey through life with cancer. The toll on one’s emotional and physical well-being, coupled with the stress of financial decisions, can be rather overwhelming.

International Cancer Specialists (ICS) was founded in 2008 with the purpose of addressing these concerns. We treat every patient as a human being first and foremost, worthy and deserving of the dignity, care and support we would give to a close friend or family member.

Our Insurance Partners

Local & International Insurance Partners


As a cancer treatment and management centre in Singapore, we provide various services including medical oncology, haematology, cancer-focused health screenings, and a valuable second opinion.

For foreign patients, we also provide advice on travelling to get treatment in Singapore, and face-to-face teleconsultations at your convenience.

ICS offers Cancer-Focused Health Screenings that are focused on detecting cancer early before the appearance of any symptoms. All of your results will be evaluated by our Senior Medical Oncologist with over 15 years of practicing experience.

As Lung Cancer is one of the most common cancers in the world, ICS offers a Lung Cancer-Focused Screening Package. It uses Low-Dose CT scans that contains over 5 times less radiation than Traditional CT Scans and is recommended for individuals at risk of Lung Cancer, i.e individuals exposed to secondhand smoke.

Our treatment plans feature a patient-involved process with our specialists, while taking into account your insurance coverage, in order to create a personalised treatment plan.

The frequency, duration of the treatments, and the required dose for each session are then communicated to the patient.

After the first consultation, the number of treatment sessions we would recommend you to attend will differ based on your individual case and needs. We would assess your current condition during the treatment and compare it to the last time you visited us.

If you are recovering, the appointment sessions may be more staggered. However, should an unexpected turn happen during the period between the two appointments, we may increase the frequency of the appointments.

A second opinion for a cancer diagnosis can help you understand your different treatment options. This is especially crucial if you have a rare type of cancer, or if treatment options are limited in your country.

Even if standard treatment protocols exist for a particular type of cancer at a specific stage, there can be a variation in treatment, depending on the individual and their medical history.

Different doctors will likely have their own set of approaches to treating cancer, such as the type of treatment, the treatment schedule, or the supportive therapies provided.

Going through cancer diagnosis and treatment at a cancer treatment centre can be an emotional journey. Fear, anxiety, and depression can happen while the patient is coping with the treatment, such as those experiencing side effects during chemotherapy. That is why we believe it’s crucial to address how the patient is coping.

ICS also offers counselling and dietary consultations for our patients to assist with the coping of side effects and to provide any emotional support needed.

Unknown to many, private cancer treatment may actually be within reach for many of us. Over the past 15 years, International Cancer Specialists has been helping our patients process their treatment claims from multiple insurance companies in Singapore and around the world. As such, our patients from all walks of life have been able to comfortably finance their treatments.

Be at ease as at ICS you never walk alone, let us plan for financing together. Upon your visit to ICS for treatment, we provide free financial counselling to assist you to make an informed choice on finance matters. Our team of nurses with years of experience in handling international, local, and corporate insurance stand ready to assist with any issues with the financing of your treatment that you may have.
