There are three kinds of common skin cancers: basal cell carcinoma, squamous cell carcinoma and malignant melanoma, which have different symptoms on the skin:
1. basal cell carcinoma
The most common skin malignant tumor, mainly occurs in the elderly, mostly in the exposed parts of the face, back of hands and forearms. Almost no metastasis, and the success rate of surgical treatment is very high.
It may be a single or several red, flesh colored or black tumors, and will gradually grow.
Sometimes ulcers and bleeding occur.
Microvascular dilation can be seen around the tumor.
A pink, translucent, glossy pearlescent projection.
2. squamous cell carcinoma
The second most common skin malignancy, also occurs in the elderly, is most common in the sun, especially in the face. There is a low probability of internal organ metastasis. If found early, the success rate of surgical treatment is very high.
It may be a single or several tumor or ulcer with red or fleshy appearance and gradually growing up.
The appearance of the tumor is sometimes covered with a layer of scaly dander.
3. malignant melanoma
The most malignant skin cancer is characterized by pigmented nevus, which may occur in any part of the body, and is very easy to metastasize to local lymph nodes and other internal organs, including liver, lung, brain and bone, with high mortality. It may occur in all age groups, especially in the middle-aged and elderly.
