What are the symptoms before death from advanced skin cancer?

With the progress of the times, people's living standards are getting higher and higher. While you are enjoying life with your family, have you ever thought about paying attention to some cancers? Although modern technology is advanced, due to the hidden nature of skin cancer, the symptoms of early cancer patients are extremely subtle. Clinically, it is found that most skin cancer patients have already reached the middle and late stages when they show obvious symptoms. Here, we remind our friends that even if you are not sick, you should pay attention to it. Even if you don't consider yourself, you should consider your family. The health of your family is your own health.

Symptoms of advanced skin cancer

Squamous cell carcinoma

It accounts for about 90% of skin cancer. It is common in the age of 30 to 50 years old. The tax accountant's office was originally transformed from keratosis, mucosal leukoplakia and other precancerous diseases. The most common sites are the eyelids, nose, lips, temporal, cheeks, forehead, limbs, and foreskin, glans penis, and trunk. At first, it is dark red, hard, and higher than the skin surface. The stratum corneum on the surface will fall off and a red erosion surface will appear, accompanied by bleeding and exudate, and the lesion will gradually expand. It grows faster and ulcers will form in the early stage. Squamous cell carcinoma is often accompanied by purulent infection, accompanied by odor and pain. Regional lymph node metastasis is common, and giant squamous cell carcinoma has an incomparable odor, more purulent secretions, and is easy to bleed; when cervical lymph node metastasis occurs, the site of the disease is the mucosal skin junction. Squamous cell carcinoma develops fastest, and patients with heater mucosa are more likely to metastasize. Lower limb skin cancer metastasis occurs more frequently, followed by the back of the hand and the face and neck. Hematogenous metastasis is rare, and the lungs are the most common metastatic organs.

Generally divided into 4 types, the most common is nodular ulcerative type

1. Nodular ulcer type: Yunnan travel begins with a waxy nodule of millet to pea size on the epidermis, with a hard texture and a few dilated capillaries on the surface, slightly higher than the skin surface, or just like erythema but not raised, or slightly nodular, with the surface skin slightly sunken. The nodule may gradually expand or new skin lesions may appear, merging with each other to form a disc-shaped plaque with a waxy luster, with a brown, yellowish brown or dark gray scar in the center, followed by ulcers under the scab, which gradually expand to form round, oval or irregular ulcers. The size of skin cancer varies from a ring to a copper coin. The edge of the ulcer is firm and rolled up, often translucent and uneven, with no inflammation on the surrounding skin, and the bottom has a pearly or waxy appearance. Sometimes the surface of the lesion is completely covered by scabs. The ulcer slowly expands to the surrounding and deep parts, like a rat bite, forming a typical clinical form of basal cell carcinoma, so it is called erosive ulcer. The ulcer can partially heal and cause scarring, and can also extend to the subcutaneous tissue and even cartilage and bone. Various tissues can be destroyed and form deep pits. If it occurs on the face, it can destroy the cartilage and bone tissue of the nose, ears, orbits, maxillary sinus, etc., causing bleeding or intracranial invasion or disfigurement.

2. Pigment type: The nodules are relatively flat and shallow, and the lesions are the same as those of the nodular ulcer type. Because it contains more pigments, the edges of the lesions have a pearly luster, as well as dark brown or black-brown pigment spots in the form of dots or reticular patterns, and pigmentation can also be seen in the central part. The locker is prone to bleeding when the scab is removed, and dark brown or even carbon black particles may appear under the scab, which is similar to malignant melanoma and is easily misdiagnosed.

3. Morphosis or fibrotic type: commonly seen on the head and neck, appearing as hard, light yellow or yellowish-white plaques, slightly raised, with unclear boundaries, similar to morbidity, which can remain intact for a long time and finally rupture.

4. Superficial type: The lesions are superficial, mostly occurring on the trunk, presenting as one or several infiltrative erythema, with desquamation or crusting on the surface, and the edges or the entire lesion are slightly raised, with at least a portion of the edges presenting small pearl-like or linear embankments. This type may eventually become fibrotic. The online store system is similar to psoriasis, eczema or seborrheic dermatitis. Basal cell carcinoma lesions develop slowly, and generally rarely metastasize to regional lymph nodes, and there is no distant metastasis.

Basal cell carcinoma

It is common in people over 50 years old. The most common sites are epidermal sebaceous glands and exposed parts that are often exposed to sunlight, such as the nose, eyelids, upper and lower lips, forehead, chin, etc. It is rare in the front of the ears, neck and back of the hands. About 10% of cases occur on the trunk. Basal cell carcinoma grows slowly. It starts as a small nodule slightly higher than the skin surface in light yellow or pink. It often presents as a pearly nodule with obvious capillary dilation, hard texture, often without pain or tenderness, and slowly infiltrates to the surrounding area. There may be superficial ulcers in the middle of larger lesions. The edges of the ulcers are jagged and worm-eaten. They do not heal for a long time, but the pearly characteristics are still maintained at the edge of the tumor. Some lesions have scaly desquamation. Some basal cell carcinomas are accompanied by melanin deposition. The melanin spreads in the lesions and merges into black or brown, which is called pigmented basal cell carcinoma, which is easily misdiagnosed as malignant melanoma. Basal cell carcinoma mainly grows in a local infiltrative manner. Basal cell carcinoma of the nose wing and auricle can destroy cartilage. Basal cell carcinoma occurring in the scalp can infiltrate the skull and dura mater. Generally, there is no regional lymph node metastasis.

Malignant melanoma

A tumor produced by melanocytes in the skin and other organs. Primary melanomas are all caused by the proliferation of melanocytes in the epidermis, which manifest as densely pigmented nodules that gradually increase in size and may be surrounded by a red halo. Its incidence is relatively low, but it is highly malignant, metastases occur early, and has a high mortality rate. Malignant melanomas mostly occur in adulthood. It starts as a pigmented spot, ranging from brown to black, and the color is often uneven, with different depths and irregular edges. Later, it may gradually expand and bulge into plaques, nodules or lumps, and even ulcerate, bleed, and finally metastasize. According to clinical manifestations, malignant melanoma can be divided into the following 4 types: melanoma in situ, superficial disseminated melanoma, nodular melanoma, and malignant lentigo melanoma. Once diagnosed, surgical resection should be performed in a timely manner. For cases suspected of metastasis, chemotherapy should also be combined with surgery.

The symptoms of skin cancer can be distinguished into three types of skin cancer. Basal cell carcinoma is the most common, followed by squamous cell carcinoma, and finally malignant melanoma. 80% of skin cancer deaths are caused by malignant melanoma. Basal cell carcinoma and squamous cell carcinoma are curable. Early diagnosis is the key to successful treatment of skin cancer.

The above is a brief introduction to "What are the symptoms before death from late-stage skin cancer?" For people who are related to the pathogenic factors of skin cancer, it is recommended to take preventive measures for skin cancer and follow the doctor's instructions and then receive specific treatment. I hope that patients can recover soon! If you have other questions about skin cancer, please consult our experts online or call for consultation.
