What are the symptoms of skin cancer

Nowadays, more and more people suffer from skin diseases. There are many manifestations of early skin cancer. Skin cancer patients can only have a good control after active treatment in the early stage. Regarding some treatments for skin cancer, you should pay attention to understanding in life. What are the symptoms of skin cancer?

1. Squamous cell carcinoma is often transformed from keratosis, leukoplakia and other precancerous diseases. It grows rapidly and forms ulcers in the early stage. Some are nodular or cauliflower-shaped, with less invasion into the deep part and a movable base; some are butterfly-shaped, with more obvious infiltration into the deep part and great destructiveness, often involving bones.

Squamous cell carcinoma is often accompanied by purulent infection, with foul odor and pain. Regional lymph node metastasis is common. Patients with huge squamous cell carcinoma on the head have an extremely foul odor, more purulent secretions, and are prone to bleeding. When cervical lymph node metastasis occurs, the site of the disease is the mucosal skin junction. Squamous cell carcinoma develops fastest, and mucosal disease is more likely to metastasize.

2. Basal cell carcinoma is often asymptomatic at the onset. In the early stage, it is mostly plaque-like papules with hard bases, and some are wart-like protrusions, which then break down into ulcers. They are irregular, with raised edges, like craters, and uneven bottoms, and grow slowly. Metastasis is rare, and the ulcers are shallowly ulcerated with translucent nodules on the edges, which then gradually expand and can erode surrounding tissues and organs, becoming erosive ulcers.

3. Squamous cell carcinoma is more common in people aged 30 to 50, while basal cell carcinoma is more common in people over 50. The former develops quickly and often grows rapidly in a short period of time; the latter develops slowly. Squamous cell carcinoma is more common in the lower lip, tongue, nose, vulva, and at the junction of the skin and mucous membrane. The ulcer has a high edge, is red and hard, and is ring-shaped and cauliflower-like in appearance. The surrounding inflammatory reaction is significant, and there are often regional lymphadenopathy.

Basal cell carcinoma often occurs in the eye sockets, inner canthus, nose, cheeks, forehead, and back of hands; the edges of the ulcers are waxy, nodular, and rolled up, and some are black. The inflammatory reaction is mild or absent, and metastasis is very rare. It mainly infiltrates into deep tissues.
