A major component of health screening involves cancer screening. Cancer remains a leading cause of morbidity and mortality in Singapore, accounting for 29.7% of deaths in 2015 according to the National Registry of Disease Office of Singapore.

The thought of screening for cancer can be distressing. One may even argue that by identifying cancer, it will be life-changing, life-defining, even death-sentenced without a cure to the problem. On the flipped side, even without curative treatment to the disease, early detection promises a better disease prognosis and a better quality of life with current modern medicine in comparison to cancer cases that are detected at late stages.

In certain cancers, early screening can in fact be life-saving. This is where health screening comes in place. Screening has been shown to be effective in early detection of colon cancer, breast cancers and cervical cancer. This article is written in the hope to give certain guidance and recommendation to people on choosing cancer screening packages.

Colonoscopy, though not completely risk-free, is not overtly scary. Colonoscopy is a planned procedure arranged between you and your endoscopist. Prior to the procedure, you are advised to drink a medicine liquid 1 to 2 days prior procedure to clear out your bowels. You will be given sedation throughout the procedure to ease your discomfort. The procedure itself takes about 15 to 30 minutes, allowing your doctor to visualize your colon intestinal walls, and take sample biopsies or remove small polyps during the procedure.

Breast cancer

Cervical Cancer

You are recommended cervical cancer screening from the age of 25 onwards if you have ever had sexual contact. You are recommended for pap smear test at least once every 3 years. You are also advised for HPV test every 5 years if you are sexually active and over the age of 30.

While pap smear and HPV tests can be uncomfortable, early treatment is curative. Early treatment of cervical cancer is particularly important to women during their reproduction years for future conceive and childbearing.

What cancer symptoms or warning signs I should be aware of?
