Uv radiation remains the most significant and modifiable risk factor for skin cancer. This may include cumulative exposure to UV light, or sudden exposure to high levels of UV light three or four times. Uv radiation can cause DNA damage in the skin, which can lead to skin cancer. This is why skin cancer occurs in areas that are easily exposed to the sun, such as the nose, around the eyes, the forehead, and exposed arms. Between 2016 and 2018, about 45 percent of all skin cancer cases treated at National University Hospital with "MOE microsurgery" were skin cancers of the nose. Other risk factors include fair skin, a history of skin cancer, and a history of immunosuppression or radiation therapy.
Skin cancer can be divided into "non-melanoma skin cancer" (NMSC) and "melanoma skin cancer". The former consists of basal cell carcinoma and squamous cell carcinoma. The latter is more likely to be fatal, and risk factors include a family history and many or abnormal moles. Fortunately, the most common local cases of skin cancer are "non-melanoma skin cancers."

Skin cancer varies in appearance. Be careful if there are abnormal spots, bumps, or bumps on the skin. Skin cancer sometimes has no obvious symptoms. Other times it may be painful, itchy, bleeding, or even a wound that is difficult to heal. If a rash develops on an area of the body that does not respond to treatment, or a mole that is deformed and discolored, this may also be skin cancer.
The most common skin cancer in Singapore is basal cell carcinoma. This type of skin cancer occurs in Asian people, most of whom develop pigmented lesions. Because this type of skin cancer can exist innocently for a long time, patients often don't find it easily, or they don't care, and only seek medical attention when it gets bigger or begins to ulcerate bleeding. Squamous cell carcinoma is the second most common form of skin cancer, but it grows quickly and forms thick, hard nodules or bumps on the skin that cause pain, sores or bleeding, or form wounds that don't heal. This type of skin cancer is much more serious than basal cell carcinoma.
As for melanoma skin cancer, we often start from the mole deformation, for example, become asymmetric information, the edge is uneven, the presentation of a variety of methods of different product colors, the area continues to expand to more than 6 mm; Or a new mole that starts to feel painful, itchy, bleeding, thickened, and irregularly shaped. These cancerous moles may not appear on any part of a person's body, including the palms and soles of the feet.
In cases of suspected skin cancer, doctors will first arrange for the patient to undergo a skin biopsy to confirm the diagnosis, and then conduct further tests based on the test results.
