What Is Cancer, The Top Cause Of Death In Singapore?
Cancer in Singapore – Cancer is a group of diseases characterised by the uncontrolled growth and spread of abnormal cells in the body. These abnormal cells can form a mass of tissue called a tumour, which can be benign (not cancerous) or malignant (cancerous). Malignant tumours have the potential to invade nearby tissues and organs, as well as to spread to other parts of the body through a process called metastasis.
Cancer can develop in virtually any part of the body, and there are more than 100 different types of cancer, each with its own unique characteristics and behaviour.
Cancer In Singapore
Cancer is the #1 cause of death in Singapore, accounting for 28.2% of all deaths from 2017-2021.
There were 84,002 new cancer cases reported, with 49% of those being for males and 51% for females.
The median age of cancer diagnosis among males was 68, whereas for females it was 64. However, a significantly larger proportion of female cancer patients were aged 59 and below (41%) compared to male patients (24%).
1 out of 4 people in Singapore may develop cancer in their lifetime
What Causes Cancer?
Cancer is a result of a combination of factors. Some of the key factors that can contribute to the development of cancer are genetic mutations, environmental factors such as UV, radiation, and chemical exposure as well as lifestyle factors such as diet, alcohol consumption, and tobacco use.
What Are The Symptoms Of Cancer
Some of the common signs and symptoms of cancer includes:
- Fatigue
- Unexplained weight loss
- Ongoing pain
- Changes in the skin
- Changes in bowel or urinary habits
- Persistent cough
- Lumps or swelling
- Difficulty swallowing
- Breathing problems
- Bleeding
The top 5 cancers for males by incidence were prostate cancer, colorectal cancer, lung cancer, lymphoid neoplasms (cancers of the lymphatic system), and liver cancer. In terms of cause of death, the top 5 cancers for males were lung cancer, colorectal cancer, liver cancer, pancreatic cancer, and prostate cancer.
On the other hand, the top 5 cancers for females by incidence were breast cancer, colorectal cancer, lung cancer, uterus cancer, and lymphoid neoplasms. In terms of cause of death, the top 5 female cancers were breast cancer, colorectal cancer, lung cancer, pancreatic cancer, and liver cancer.

Is Cancer Preventable?
While cancer may not always be entirely preventable, many cases of cancer are linked to known risk factors. Doing regular screenings and adopting a healthy lifestyle may significantly lower your risk.
Importance Of Cancer Screening
Many cancers often do not present any symptoms until they have become advanced. What we can do to protect ourselves against the risk of getting cancer is to go for regular cancer screenings. Cancer screening are carried out on people who are asymptomatic (i.e. not experiencing any symptoms of cancer) with the objective of detecting cancer while it is still in the early stages and is more easily treatable.
Top Silent Killer Cancers
Cancer may have little or no symptoms in the early stages, or have symptoms that are very similar to other conditions. Cancers that are often considered “silent killer” include:
- Pancreatic cancer (among top 5 leading cancer deaths in males and females)
- Colorectal cancer (among top 5 leading cancer deaths in males and females)
- Liver cancer (among top 5 leading cancer deaths in males and females)
- Lung cancer (among top 5 leading cancer deaths in males and females)
- Prostate cancer (among top 5 leading cancer deaths in males)
- Cervical cancer
- Ovarian cancer
Survival Rate For Cancer In Singapore
According to the Singapore Cancer Registry, the five-year Age Standardised Relative Survival for cancers diagnosed at Stages I, II, III and IV were 91.7%, 81.4%, 56.0% and 18.6% respectively. The ten-year ASRS for cancers diagnosed at Stages I, II, III and IV were 87.6%, 76.1%, 47.4% and 13.7% respectively.
Based on the figures, Stage I cancers have the highest survival rate, 91.7% for five-year ASRS and 87.6% for ten-year ASRS. This highlights the importance of regular cancer screening to detect cancer at its early stages when it is more treatable.
Case Study: Comparison Between Cancer Screening In South Korea Vs Singapore
Data from World Cancer Research Fund International shows that the age-standardised rate for South Korea was at least 75.3 per 100,000 in comparison to Singapore with 111.3 per 100,000. This may be attributed to a combination of factors including comprehensive public health infrastructure, technological advancements, multidisciplinary treatment approach, and patient education initiatives. Aside from these, early detection and screening efforts also play a crucial role in South Korea’s initiative.
It can also be noted that South Korea’s national recommendation for cancer screening is more comprehensive in comparison to Singapore which includes stomach and liver cancer screening aside from colorectal, breast, and cervical cancer which are among Singapore’s recommended cancer screenings.

Diagnosis
Cancer diagnosis typically follows cancer screening. If a screening test indicates a potential problem, further diagnostic tests may be ordered by healthcare professionals to confirm whether cancer is present. Some of the common diagnostic tests are:
- Biopsy – During a biopsy, a small sample of tissue is extracted from the suspected area for examination under a microscope.
- Imaging Tests – Imaging techniques like X-rays, CT scans, MRIs, and PET scans are used to visualise internal structures and detect tumours.
- Blood Tests – Blood tests, such as tumour markers and complete blood counts, can reveal abnormalities indicative of cancer. There are also biomarker blood tests that detect biomaterials associated with cancer cells. An example is GASTROClear™ by MiRXES, which has high accuracy for stomach (gastric) cancer testing.
- Endoscopy – Involves using a flexible tube with a camera to examine the inside of organs. Some common types are gastroscopy and colonoscopy.
- Genetic Testing – Identifies specific gene mutations linked to an increased risk of cancer.
Treatment
There are many cancer treatments available. The choice of treatment methods depends on several factors, including the type and stage of cancer, the patient’s overall health, and preferences. Some of the common cancer treatments are:
- Chemotherapy – Involves the use of drugs (chemotherapeutic agents) to kill or inhibit the growth of cancer cells. It is typically administered through the bloodstream and can reach cancer cells throughout the body.
- Radiation Therapy – Uses high-energy beams, such as X-rays or protons, to target and destroy cancer cells.
- Surgery – Involves the physical removal of cancerous tumours or affected tissues from the body.
- Immunotherapy – A treatment approach that harnesses the body’s immune system to identify and attack cancer cells.
- Targeted Therapy – Uses drugs that specifically target the molecular abnormalities or specific proteins involved in cancer growth.
- Hormone Therapy – Works by blocking or reducing the production of hormones that fuel cancer growth.
- Stem Cell Transplant – Also known as a bone marrow transplant. It is used to treat certain blood cancers and disorders affecting the bone marrow.
Types Of Oncologists
Cancer is a complex disease that requires treatment by specialised medical professionals called oncologists. These medical professionals are trained to diagnose, treat, and manage different types of cancer.
