Early detection is one of the best weapons we have against cancer.  For this reason, cancer screening is recommended for all individuals, even those without any symptoms.  Beyond the possibility of avoiding death, screening may reduce cancer morbidity as it increases the chances of detecting cancers at their early stages.

Overview of Early Cancer Detection

Some Common Cancer Screening Tests

 


 
“The chance of successful treatment and cure is better when the cancer is treated in the early stages.  This can only be achieved through early cancer screening, provided early, effective screening methods are available” says Dr Benjamin Ng, an Occupational Physician at Raffles HealthScreeners.  Dr Ng adds that many cancers do not display obvious symptoms until the advanced stages.  These include lung cancer, brain cancer, stomach and colon cancer, prostate cancer, and liver cancer.
 
It is important to note that none of us is immune to the risk of cancer even if we do not have any family history or if we are meticulous in our lifestyle. That said, we can gain an edge against the illness through health screenings. Detecting cancer at an early stage improves our chance of survival and cure.  However, many people remain hesitant about going for screening. “
 
There will always be a few patients who are fearful of being diagnosed with cancer because they feel that it is the end for them.  They sometimes fear that they will be a burden to their closed ones and think that there is no hope.  Sometimes they are in denial and hence delay seeing a doctor. Some of them, especially the elderly, are ignorant,” shares Dr Hoo Kai Meng, a Family Physician at Raffles Cancer Centre.
 
A substantial number of people also have a fear of the treatments (e.g. surgery and chemotherapy) that may be required.  For some, the possible costs of investigations and treatments weigh upon them and stop them from seeking a doctor’s opinion even when they exhibit symptoms that may be related to cancer.
 
Currently, there are many advances in cancer treatment which improve the survival rate of patients with cancer and they do not cause too many severe side effects.  Indeed, advances in cancer treatment such as newer chemotherapy regimens, monoclonal antibodies, targeted therapy and hormonal therapy are in place to offer patients options that were previously unavailable.”
 
Said Dr Hoo. “Early screening is important if you have a higher than average risk of getting cancer, such as having a strong family history of breast cancer or colon cancer.  Screening is also important if your occupation exposes you to radiation or cancer causing chemicals,” said Dr Hoo. Healthy individuals may put off going for screening, as they may not see a need for it.  However, the choice should be clear as finding cancer at an early manageable stage improves survival rates.

Are you unsure of what the various screening tests are about?  Here is what you can expect from some of the common screening tests.
 
Colonoscopy

What to expect:  The doctor inserts a colonoscope (a long, thin, flexible tube) into the anus.  Pain medication and a sedative (medication that causes drowsiness) are given to help reduce discomfort.
 
Preparation guidelines:

As your colon must be empty, you will need to be on a diet of clear liquids for one to three days before the procedure.

In addition to the liquid diet, you will need to take a laxative or give yourself an enema the day or night before the colonoscopy.

 

Digital rectal examination

What to expect:  In this test, a doctor inserts a gloved finger into the rectum to feel for anything abnormal.  This takes only a few minutes to complete and is performed without sedation.
 
Preparation guidelines:  No advance preparation required.
 
Mammography

What to expect: This is basically an x-ray of the breast. Generally, mammography is uncomfortable but rarely painful.  Some women do find the procedure painful, as the x-ray plates are compressed firmly.
 
Preparation guidelines:

On the day of your mammogram, do not use deodorant, anti-perspirant, powder, lotion, or perfume on your breasts or under your arms.  Avoiding caffeine for a week prior to the examination and taking an over-the-counter pain medication the day of the examination may also reduce breast sensitivity and make the examination more comfortable.
 
Pap smear

What to expect:  Cells are gently scraped from the outside of a woman’s cervix and vagina and examined.  This only takes a few minutes.  The test can be uncomfortable, but it is not usually painful.
 
Preparation guidelines:

To ensure that the Pap test results are as clear as possible, do not have sexual intercourse for two to three days before the test.

Do not use tampons, birth-control foams, vaginal medicines, douches, or vaginal creams or powders for two to three days before the test.  These products may wash away abnormal cells.
