Screening is the checking of your body for cancer when you do not have any symptoms. If you are regularly screened for cancer, it helps you to detect cancer early when it is easier to treat. Being proactive will help you detect to protect your health and well-being.
There are well established screening tests which can be used to detect some of the common cancers found in Malaysia. Do speak to your doctor to determine what is suitable for you based on your risk for cancer.
Mammograms are useful in breast cancer screening to detect the presence of tumour before the lump is big enough to be felt or for symptoms to show.
This digital mammography system uses low dose X-rays to produce internal images of the breast tissues. Patient’s exposure time to radiation dose is minimised. Unique features are also in place to help calm and reassure women throughout the entire mammography procedure.
Who should go for mammography?
- Women aged 40 to 49 years: Speak to your doctor about when to start and how often to get a mammogram.
- Women aged 50 to 74 years old and are at average risk for breast cancer: Get a mammogram every two years.

Pap test helps detect abnormal cells in the cervix before they become cancerous. Learn more about pap test.
The HPV test looks for the human papilloma virus which can cause cell changes. The test does not tell you if you have cancer, but the detection of the presence of HPV increases your risk of cervical cancer.
An HPV test is usually done at the same time as a Pap test. Your doctor will insert a speculum to push apart your vaginal wall, followed by a spatula to collect cells from your cervix. These cells will then be sent to the laboratory for testing.
Who should go for Pap test and HPV test?
Women aged 21 to 29 years: Start getting Pap tests at age 21 or after 3 years of vaginal intercourse. It should be done yearly till the age of 30, and women whose pap smear results show no abnormalities for 2 consecutive years can be tested every three years.

Your doctor inserts a short, lighted tube into your rectum and checks for polyps or cancer in your rectum and lower colon.
X-rays and computers are used to produce images of your entire colon for your doctor to check.
Each test has its advantages and disadvantages. Please speak to your doctor to determine which is suitable for you.

Low-dose computed tomography (LDCT)
This procedure uses a computer linked to an X-ray machine that gives off low doses of radiation. During a scan, you will be asked to lie down on a table and the machine will produce a series of detailed images of your lung for your doctor to examine.
Who should go for yearly lung cancer screening with LDCT?
- Have a 20 pack-year* or more smoking history, and
- Smoke now or have quit within the past 15 years, and
- Are between 50 and 80 years old.
*A pack-year is smoking an average of one pack of cigarettes per day for one year. A person could have a 20 pack-year history by smoking one pack a day for 20 years or two packs a day for 10 years.

Diagnosis is made based on various investigations. Your doctor would first question you about your general health and symptoms. Then, your doctor may employ one or more of the following approaches.
During a physical examination, your doctor examines your body for any unusual physical changes. Your doctor may look for lumps or abnormalities such as changes in skin colour. If breast cancer is suspected, your doctor may check for lumps in your breasts. An examination of the skin that reveals a yellowish tinge could be indicative of liver cancer.
Unusual levels of certain substances in your body that are not within the normal range can be a sign of cancer.
Laboratory tests can be conducted to help your doctor to identify abnormal changes that may be caused by cancer. These tests include urine test, blood test, and tumour marker test.
Tumour markers are substances which are often proteins found in blood, urine, or body tissues. They are produced by cancer cells or by other cells in response to cancer and may be used to support a diagnosis of cancer. Common tumour markers are:
- Carcinoembryonic antigen (CEA): To detect colorectal (colon) cancer
- Prostate-specific antigen (PSA): To detect prostate cancer
- AFP (Alpha-fetoprotein): To detect liver cancer, ovarian cancer, testicular cancer
- CA 125 (cancer antigen 125): To detect ovarian cancer (an elevated CA 125 is the most common indicator for ovarian cancer), uterine cancer, cervical cancer, pancreatic cancer, liver cancer, breast cancer, lung cancer
- CA 19-9 (cancer antigen 19-9): To detect colon cancer, stomach cancer, bile duct cancer
- CA 15-3, CA 27-29 (cancer antigens 15-3 and 27-29): Most commonly used in women with advanced breast cancer
A biopsy is usually the definitive way to diagnose cancer. During a biopsy, the doctor collects a sample of cells. These cells are then examined under a microscope in the laboratory and some tests may also be carried out.
A biopsy may be carried out in several ways:
- Needle: A needle is used to obtain a sample of tissue or fluid. This may be used to obtain prostate or liver biopsies.
- Endoscopy: A thin, lighted tube (endoscope) is inserted through body openings such as your mouth or anus and the abnormal tissue and some surrounding normal tissue is removed through the endoscope. For example, a colonoscopy is an endoscopic examination of the colon and rectum, whereas a bronchoscopy examines the trachea, bronchi, and lungs.
- Surgery: An area of abnormal cells is removed by a surgeon during surgery. A surgical biopsy may be carried out to remove a breast lump for breast cancer diagnosis or lymph nodes for a lymphoma diagnosis.
Imaging tests allow your doctor to ‘look’ inside your body non-invasively to determine whether there is a tumour present. Some of the imaging tests used in diagnosing cancer are X-ray, ultrasound, Computerised Tomography (CT) scan, Positron Emission Tomography (PET) scan, Magnetic Resonance Imaging (MRI).
