Symptoms of bone metastasis from skin cancer

If we do not understand the true face of skin cancer, or even do not know that we have skin cancer, it is easy to miss the opportunity to treat skin cancer and let skin cancer develop to the late stage. Therefore, experts point out that when skin cancer develops to the late stage, patients should pay more attention to the characteristics of their disease so that they can better treat skin cancer.

1. Squamous cell carcinoma is often transformed from keratosis, leukoplakia and other precancerous diseases. It grows fast 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, great destructiveness, and often involving bones. Squamous cell carcinoma is often accompanied by purulent infection, accompanied by malodor and pain. Regional lymph node metastasis is common. The author encountered a huge squamous cell carcinoma in the head, which had an extremely bad odor, more purulent secretions, and easy bleeding; cervical lymph node metastasis occurred. The site of the disease is the junction of the mucosa and skin. Squamous cell carcinoma develops fastest, and those with mucosal disease are more likely to metastasize.

2. Basal cell carcinoma is often asymptomatic at the onset. In the early stage, it is mostly plaque papules with hard bases, some of which are wart-like protrusions, and then break into ulcers, which are irregular, with raised edges, like craters, and uneven bottoms, and grow slowly. Metastasis is very rare, and first occurs as a shallow ulcer with translucent nodules on the edges, and then gradually expands, which can erode surrounding tissues and organs and become 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 is slow. 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 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 is more common in the eye socket, inner canthus, nose, cheek, forehead, and back of the hand; the ulcer edge is 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.

Experts remind: Some people often do not go out, so the melanin in their skin gradually decreases. If you suddenly go out at noon without an umbrella, the ultraviolet rays can easily damage our skin and cause us to have symptoms of "sun spots". If you do not pay attention to body care at this time, skin cancer can easily occur.
