What are the mid-stage symptoms of skin cancer

What are the symptoms of skin cancer in the middle stage? Skin cancer is a common malignant tumor. With the rapid development of society, the quality of the environment has been declining, resulting in stronger ultraviolet rays, holes in the ozone layer, and radiation from various electronic products, etc., all of which may lead to skin cancer. So what are the symptoms of skin cancer in the middle stage?

1. Basal cell carcinoma is a very slow-growing cancer. It is more common in the elderly and is prone to occur in the forehead, eye sockets, eyelids, nose, and around the ears. It is less malignant and grows very slowly. At the beginning, it is mostly a small thickened mass that gradually bulges and infiltrates around it, and rarely metastasizes.
2. Squamous cell carcinoma Squamous cell carcinoma is highly malignant and often occurs in the skin, mucous membranes and the junction of the skin and mucous membranes of the head, neck, limbs, trunk and other parts. Early squamous cell carcinoma appears as wart-like spots or small light red or light yellow nodules with keratinized apical spines. It continues to grow, ulcerates in the center, and has raised and congested edges. It grows in an invasive manner and is often accompanied by purulent infection and lymph node metastasis when it invades deep tissues.
3. Malignant melanoma is more common in white people between the ages of 30 and 60. About one-third of melanoma cases grow from normal moles. Changes in pigmented skin lesions often indicate the possibility of early malignant melanoma: for example, most malignant melanomas are unevenly mixed with brown, black, red, white or blue. When a mole changes color, you should be particularly vigilant; it is often jagged and jagged; the surface is not smooth, often rough and accompanied by scaly or flaky desquamation; the skin around the lesion becomes edematous or loses its original skin luster or turns white or gray; it is often itchy, burning or tender to the local area.
