Skin cancer
This list is provided by the popular medical science project the platform of the National Health and Medical Commission / the Medical
Encyclopedia Network.
Skin cancer is a malignant tumor of the skin. It has different
names All Cancers according to the origin of the cancer cells, including the epidermis, the epidermis, the soft skin tissue, the peripheral nerves, melanocytes reticulum,
lymph nodes, skin, and hematopoietic tissue. Another part is metastatic tumors
that spread to the skin.
Basic information
The English name, consultation, skin cancer, skin, cancer, the common cause of ultraviolet radiation, carcinogens, chronic inflammatory
chemicals, and other common symptoms, bleeding, ulcers, infection combined with
foul-smelling pus. No infection
Causes of disease
The cause of this disease is not clear, and its occurrence maybe
related to the following factors: exposure, daily exposure, and ultraviolet
radiation ② long-term stimulation of chemical
carcinogens such as asphalt, benzene derivatives, copy screening Chronic
radiation And inflammation such as chronic wounds, lasting fistula, discoid
lupus, radiation dermatitis, etc; ⑤ Other: such as
immune phase, a carcinogen, virus, etc.
Typing
Skin cancer, including squamous cell carcinoma, basal cell
carcinoma, skin cancer, idiopathic lymphoma, idiopathic erythroid cancer, sweat
gland cancer, sweating adenocarcinoma, and angiosarcoma. Skin cancer includes
the disease. Primary cancers and secondary cancers that have spread to the skin
from other websites. Primary skin cancers include basal cell carcinoma,
squamous cell carcinoma. The origin of diseases (Bowin), cancer cell, squamous,
like cancer, eczema and skin cancer.
Clinical symptoms
Skin cancer with bleeding is relatively easy and common is base
cell cancer and squamous cell carcinoma.
Squamous cell carcinoma
It can be changed by keratosis, leukoplakia and other cancers. It
grows quickly and wounds in early forms. Some forms are lumpy, milky or
cauliflower, with less invasion and the base can be moved, and some Leukemia cancer are
butterfly-shaped that have a deeper penetration into the deeper, more
destructive, and often involving the bones. Squamous cell carcinoma is
complicated by infections that are sticky, foul, painless and painful. Squamous
cell carcinoma has a high level of malignancy and is more likely to spread to
lymph nodes in the general spread region.
Basic cancer cells
The attacks are usually asymptomatic. Most of the initial stages
are papules, a plaque with a heavier base, some with warts-like bulges, and
then the blisters that change in the wounds, abnormal bulges on the floor
edges, uneven growth. Slowly and so on. It occurs on the cheeks, bridge of the
nose and on both sides of the nose. Tumors are often unconscious. Although
basal cell carcinoma is malignant, there is very little spread. At the first
light of the development of superficial wounds, and then gradually expand and
penetrate. The surrounding tissues and organs became aggressive. Depending on
their morphological and pathological changes, basal cell carcinoma can be
divided into 4 types: round blister type, pigment type, heavy scar type or
fibrotic type and superficial.
3. Serious skin cancer
It is a skin cancer that is cancerous and spread quickly. Chinese
people have more pigmentation on the skin and have better protection from
ultraviolet rays. At the same time, it's important to protect the skin from the
sun, so skin cancer is quite rare in China. Because melanoma is black, it's
easy to find, so if you find dark spots on your nails, bed, nails, soles, feet,
palms, or other parts of their body. It will expand in the near future and
break easily or half of the nails become black. Hospital examination
4. Cancer like eczema
Often occurs in women who have one breast. The symptoms are
similar to eczema, the skin is red or dark red, and the surface is likely to be
excreted or bleeding, mainly in the unilateral areola area. At first, symptoms
develop slowly and some nipples may have. Fudge Easily misdiagnosed like eczema
Unilateral breast eczema in middle-aged women and long-term treatment should go
to the hospital for examination in time.
Checking
A biopsy is extremely important for the classification of skin
cancer and the selection of treatment methods.
Diagnosis
Diagnosis can be confirmed according to the clinical features and
pathological examination.
The therapeutic effect of skin cancer is closely related to early
diagnosis. Should pay attention to the highly suspected signs of early cancer: ①
skin ulcers that are sometimes not treated or have blood. Slightly out ②
bleeding and ulcer from solar keratosis or nodular protruding protrusion
symptoms; Skin or blisters that have been exposed to radiation in the past,
blisters or nodular protrusion of the sinus ④ A red skin the scar that does not fade for a long time The possibility of cancer in origin
Differential diagnosis
It should be different from chronic granulomas, specific and
non-specific lesions and photokeratitis
Treatment
Skin cancer tumors are superficial and have many methods of
treatment such as surgery, surgery, radiotherapy, light therapy, laser
treatment, physical erosion treatment of local drugs and chemotherapy.
Chemotherapy is a combination of adjuvant therapy and advanced palliative
therapy that is suitable for use in combination with other treatments. The
application can be chosen based on the location, size of cancer, the overall
condition of the patient and the level of cancer. The principle of treatment is
to remove the tumor, increase retention, maximum function and reduce the
appearance damage.
Surgical treatment
Can be used with all stages of skin cancer, surgery can be used to
remove all tumors
