3. Sun and UV Exposure

Although people associate a tanned complexion with good health, frequent direct exposure to ultraviolet (UV) radiation – either by being out in the sun or from artificial sources like a tanning bed – can damage your skin and increase your risk of getting skin cancer.

A sunburn is your skin's response to excessive UV exposure. If you are fair-skinned, you are at a higher risk of skin cancer than someone with a darker skin tone. This is because fair skin has less melanin, a pigment that protects the skin from UV rays.

Singapore has one of the world's highest UV exposure rates. On days with little cloud cover, it is common for UV radiation in Singapore to reach very high to extreme levels between 11.00am and 3.00pm.

What can you do?

Prevent sunburns and avoid excessive sun exposure. Stay in the shade if possible. When out and about under the sun, use sunscreen with a sun protection factor (SPF) of at least 15 on exposed parts of your body. Wear a wide-brimmed hat and sunglasses that provide UV protection. If you're exposed to artificial sources of UV radiation at work, always follow the safety regulations.

4. Radiation Exposure

Every day, we are exposed to both natural and man-made forms of radiation. Radiation can also come from medical imaging procedures used for X-rays and CT scans. Excessive exposure to radiation can potentially cause cells in the body to undergo changes. This may increase your likelihood of developing cancer.

Sometimes, an X-ray or CT scan is needed to help your doctor diagnose your medical condition. Radiation exposure from different sources can accumulate over time, but a one-off test is unlikely to increase your risk of cancer.

What can you do?

During these imaging tests, you can protect yourself from unnecessary radiation exposure by following safety measures such as using a lead apron. Share your concerns with your doctor.

5. Previous Cancer Treatments

Advances in cancer treatments like chemotherapy and radiotherapy have helped many people with cancer live longer. But they may also possibly increase your risk of another cancer in the future.

However, this is rare and should not affect your decision to seek appropriate treatment. It is important to first treat the cancer you have. For some cancers, radiotherapy and chemotherapy may be the best treatment option.

What can you do?

Share your concerns with your doctor. If you have completed cancer treatment, follow-up care and rehabilitation is important.
