What are the early symptoms of skin cancer

Due to the current living or working environment, the number of patients with skin cancer is increasing. However, there are still many patients who do not understand the symptoms of this disease. In fact, this is not conducive to the timely detection of this disease. The following will introduce the early 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, while others 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, accompanied by foul odor and pain.
2. Basal cell carcinoma is often asymptomatic at the onset. In the early stages, it is mostly plaque-like papules with a hard base, some of which are wart-like protrusions, and then break down into ulcers. They are irregular, with raised edges, like craters, and uneven bottoms, and grow slowly.
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, while 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 membranes. The ulcer has a raised 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 is more common in the eye socket, inner canthus, nose, cheek, forehead, and back of the hand. The ulcer has a waxy, nodular, and rolled edge, and some are black. The inflammatory reaction is mild or absent, and metastasis is very rare. It mainly infiltrates into deep tissues.
