癌症實況. 預防. 癌症診斷. 癌症治療. 病人支援. 皮膚癌是香港常見的癌症之一，當中非黑色素瘤皮膚癌佔皮膚癌總數的約90%。 在2021年，非黑色素瘤皮膚癌新症共有1 094宗，佔本港癌症新症總數的2.8%。 按粗發病率計算，每十萬香港人口中即有約15宗新增個案。 雖然皮膚癌於香港的發病率遠較西方低，不過本地的新症數目由2011年至2021年間亦錄得41%的顯著增幅。 雖然皮膚癌的發病率高，幸好死亡率不算很高，因為皮膚是最易觀察到的器官，出現癌變時也較易注意到。 若發現皮膚上有任何不尋常的異變，應及早求醫，即使不幸確診，亦可增加治癒的機會。 皮膚癌是甚麼？ 甚麼人較易患上皮膚癌？ 皮膚癌有甚麼徵狀？ 癌症網上資源中心.

Skin cancer — the abnormal growth of skin cells — most often develops on skin exposed to the sun. But this common form of cancer can also occur on areas of your skin not ordinarily exposed to sunlight. There are three major types of skin cancer — basal cell carcinoma, squamous cell carcinoma and melanoma. You can reduce your risk of skin cancer by ...
Where skin cancer develops
Skin cancer develops primarily on areas of sun-exposed skin, including the scalp, face, lips, ears, neck, chest, arms and hands, and on the legs in women. But it can also form on areas that rarely see the light of day — your palms, beneath your fingernails or toenails, and your genital area. Skin cancer affects people of all skin tones, including those with darker complexions. When melanoma occurs in people with dark skin tones, it's more likely to occur in areas not normally exposed to the s...
Basal cell carcinoma signs and symptoms
Basal cell carcinoma usually occurs in sun-exposed areas of your body, such as your neck or face. Basal cell carcinoma may appear as: 1. A pearly or waxy bump 2. A flat, flesh-colored or brown scar-like lesion 3. A bleeding or scabbing sore that heals and returns
Squamous cell carcinoma signs and symptoms
Most often, squamous cell carcinoma occurs on sun-exposed areas of your body, such as your face, ears and hands. People with darker skin are more likely to develop squamous cell carcinoma on areas that aren't often exposed to the sun. Squamous cell carcinoma may appear as: 1. A firm, red nodule 2. A flat lesion with a scaly, crusted surface
Skin cancer occurs when errors (mutations) occur in the DNA of skin cells. The mutations cause the cells to grow out of control and form a mass of cancer cells.
Factors that may increase your risk of skin cancer include: 1. Fair skin.Anyone, regardless of skin color, can get skin cancer. However, having less pigment (melanin) in your skin provides less protection from damaging UV radiation. If you have blond or red hair and light-colored eyes, and you freckle or sunburn easily, you're much more likely to d...
Most skin cancers are preventable. To protect yourself, follow these skin cancer prevention tips: 1. Avoid the sun during the middle of the day. For many people in North America, the sun's rays are strongest between about 10 a.m. and 4 p.m. Schedule outdoor activities for other times of the day, even in winter or when the sky is cloudy.You absorb U...
皮膚癌成因. 近年不少醫學研究指出，陽光中的紫外線——UVA及UVB是導致皮膚癌的主要元兇，由於UVA及UVB的波長能夠深入真皮層，因此有可能傷害皮膚組織，長遠會增加患皮膚癌的風險。. 紫外線一共有三種波長，分別是UVA、UVB及UVC，UVA及UVB的波長分別為310-400nm和 ...
黑色素瘤 (Melanoma) 黑色素瘤是最嚴重，也是最少見的皮膚癌。 約佔5%比率。 如果及早發現，治療成功的可能性很高。 症狀通常是出現一個新的斑點，或者痣、胎記、雀斑產生變化，這些變化可能是大小、形狀和顏色的改變。 通常會持續幾個星期、幾個月。 皮膚癌在香港普遍嗎？ 請 按此 瀏覽最新癌症統計資料. 成因和症狀. 甚麼引致皮膚癌？ 陽光中的紫外線是導致皮膚癌最主要的原因。
2021年5月7日 · 皮膚惡性黑色素瘤（Melanoma） 約佔皮膚癌的2%。 症狀包括︰ 皮膚冒出新的黑斑，或原有的膚斑或痣變大、變形或變色。 變異的過程可長達數星期甚至數月。 症狀包括︰ 病變的膚斑或痣形狀不規則，或表面凹凸不平，看似污跡，甚至出現流血或痕癢。 顏色不定，褐、黑、藍、紅、白、 淺灰色皆有可能。 由於基底細胞癌和鱗狀細胞癌共佔皮膚癌的98%，故醫學上統稱為「非黑色素瘤」（Non-Melanoma Skin Cancer）。 皮膚癌見於身體表面，比一般癌症容易發現和診治，尤其是增長較慢的非黑色素瘤，只要及早治理，通常可治癒。 如想知更多皮膚癌的資訊，請 按此 閱讀香港癌症基金會癌症小册子了解更多。
Skin cancer is a common cancer in Hong Kong, with non-melanoma skin cancers accounting for 90% of all skin cancers. In 2021, there were 1 094 new cases of non-melanoma skin cancer, accounting for 2.8% of all new cancer cases in Hong Kong. The crude annual incidence rate of non-melanoma skin cancer per 100 000 Hong Kong population was 15.
Skin cancer is the out-of-control growth of abnormal cells in the epidermis, the outermost skin layer, caused by unrepaired DNA damage that triggers mutations. These mutations lead the skin cells to multiply rapidly and form malignant tumors. The main types of skin cancer are basal cell carcinoma (BCC), squamous cell carcinoma (SCC), melanoma ...
