Signs and symptoms of skin cancer
Human skin is probably one of the most important of its values. I want to keep her pristine, smooth, beautiful. But sometimes the skin form malignant tumors. The diagnosis of skin cancer scares everyone, because it seems that the way out of this situation no. However, early treatment can give people many years of life. Therefore, it is important to detect skin cancer. About the reasons of development of disease signs and symptoms will be discussed in our material.
Causes of skin cancer
Skin cancer is a fairly common name that unites common malignant disease. They are divided into two groups: non-melanoma skin cancer and melanoma. The most common is the first type. Is squamous cell carcinoma, which develops the degeneration of cells of the upper layer of the epithelium, and basal cell carcinoma, which is formed from the basal cells of the epidermis, located in the lower part. About 80 percent of malignant skin lesions are referred to this species.
The main cause of skin cancer is damage to DNA of skin cells by ultraviolet radiation. Including crucial sunlight. In this issue of importance the following factors:
- Held in the sun time;
- Skin color — fair-skinned people are prone to tumors is most;
- The use of sunscreens.
Additional causes of skin cancer include the following factors:
- Gender (more common in women);
- Age (chance increases in older age);
- A visit to the Solarium;
- A weakened immune system;
- Infection with human papillomavirus;
- The presence of non-melanoma types of skin cancer.
Highlights five stages of skin cancer:
1. Initial (zero). The tumor is clearly delineated, not grow into the surrounding tissue.
2. The first stage. The tumor exceeds 2 centimeters in diameter, a metastasis there.
3. The second stage. Tumor more than two centimeters, there are 2 or more adverse symptom, no metastasis.
4. The third stage. The tumor grew into the surrounding bone tissue, but no metastases. Can be of different sizes, with any number of adverse symptoms.
5. The fourth stage. Diagnosed in different cases: when the size of the lymph node located on the same side where the tumor with metastases is more than three centimeters, or the cancer has spread to several lymph nodes, or the tumor has invaded the bone, or there are metastases in other organs.
Skin cancer is a fairly common cancer. Susceptibility to this disease can be found in almost any person. Interestingly, the majority of tumors occur on the scalp. Only 10 percent for the rest of the body.
Signs and symptoms of skin cancer
Signs and symptoms of skin cancer include a lot of different manifestations. One of the main people consider moles. But they themselves can’t speak about the presence of skin cancer. After all, they have many people, as a rule, they are perfectly safe. But if the surface skin is formed more and more moles with a diameter greater than six millimeters, there is cause for concern. Melanoma is very similar to a normal mole, so the growth may indicate cancer and requires treatment by the doctors.
In addition, must pay attention to the shape of the mole. Benign tumors have clear borders and symmetrical form. However, it is impossible to reliably assert that this is the exact symptom, because in any case requires medical examination and submission of appropriate tests.
No less important as a sign of skin cancer is color moles. Nevus (ie, mole dark) has a brown tint. The overflow of the pigment it becomes red, angiom. If the tumor has changed color, has a black, white or red, the call to the oncologist is necessary. The signs of skin cancer can be attributed to the homogeneity of the moles. Benign, usually solid, but cancer education have a significant differentiation in color. Here it is important to monitor any changes.
If the mole hurts, that is a consequence of the injury. It mostly happens when they are torn. But it should be temporary. If the mole does not heal, does not cease to be ill, it is better to consult a specialist. In the case of moles, if you have them, you need to follow the changes. Various changes can be for the worse, even if the moles never showed itself. Warning signs can be changes in color, shape, uniformity.
Also a symptom of skin cancer can be acne. Themselves acne are not the most obvious symptom, because they are practically at each person. At the worst scenario they go for the week. But if the same pimple that bothers you for more than a month, it’s a reason to go to the doctor.
Basal cell carcinoma there are other symptoms. These include bleeding and oozing sores that do not heal for several weeks, thickened reddened patch of skin that itches, crusts, maybe even hurt. Also produce bright red, red, pearly white bumps, colorless formation, similar to a blister, crambidae, white, yellowish or waxy skin, frequently having an uneven and unexpressed region.
Have squamous cell skin cancer other signs. For example, warts, open sores, bumps with a rough surface and hollow in the middle.
Also for skin cancer the following symptoms: itching, pain, numbness, burning, or tingling under the skin. Sometimes no symptoms may not be at all. All purely individual.
The most important thing in the treatment of skin cancer like any other disease — time to detect it. Successful therapy depends on the stage at which the cancer is found. About 85 percent success in the initial stages. Therefore, you should be more attentive to your body and any changes.
