The main symptoms of the disease
Effective treatment may depend on the reasons forwhich formed lesions of the skin. Of course, there is definitely no exact reason. But many factors increase the risk of oncological disorders in the human body. First of all, it is excessive insolation, exposure to carcinogens, ionizing radiation and others. The most common carcinogen is considered to be tobacco smoke, so more often cancer affects people who have a long enough habit of bad habits. Also, signs may worsen and manifest against a background of weak immunity. The protective function of the body decreases after various diseases. Of course, the appearance of the skin lesion depends on the form of cancer. Most often it looks like plaques, single nodes, surface erosion. Not all cases of a person noticing symptoms, so treatment begins already at a neglected stage, which significantly reduces its effectiveness. The main signs of skin cancer are bleeding, the formation of sores and painful sensations when you touch your face. Also a sign that the skin is affected by cancer, can be a thickening of the existing moles, a change in their shape, size. As a rule, a normal nevus has a regular and symmetrical shape, there should be no changes in the structure. Any changes in shape, color or size - this is an occasion to apply to a specialist in the field of oncology, since this can often become a sign of melanoma in the body. The changed birthmark starts to itch, itch, there is a burning sensation, the structure becomes more friable, it can bleed. Carcinoma (the medical name of a malignant tumor of the epithelium) is one of the varieties of skin cancer. It is the formation of cones or plaques with a shiny surface, inside of which a sore can form. Untimely treatment leads to various complications that affect other body systems. Harmful metastases spread to the lymph nodes, the disease begins to dramatically progress. Therefore, it is advisable to begin treatment at the first suspicion of the disease. As a rule, it is better to be safe and visit an experienced dermatologist who will examine the patient and take the necessary tests for diagnosis. As a rule, the study of suspicious areas on the face is accompanied by a histological study of the material. To determine the presence or absence of metastases, other additional examinations can be used. 
Effective cancer treatment
One of the most common waysremoval of cancer lesions is a surgical intervention. Surgical removal includes various methods: excision of the tumor in a classical way, electric current (electrocoagulation), cold nitrogen (cryodestruction). In any case, radiotherapy is additionally prescribed, which fixes the result obtained and does not re-form harmful cells in the body. It is much easier and more expedient to prevent the appearance of the disease than to further expose the body to sufficiently strong drugs that, together with harmful cells, destroy useful ones. Removal of skin lesions, which includes effective treatment, leaves behind scars. Therefore, further additional cosmetic procedures are required that hide the external defects on the face and restore the even surface of the skin. A modern and effective method of treating oncology is the use of a laser. After the first session, the cancer cells begin to die. The number of procedures largely depends on the severity and form of the disease. As a rule, after using the laser, a relatively small scar remains on the skin, which gradually decreases in size. The use of medications is necessary to improve the end result, but is not an independent method of treatment. One group of drugs is prescribed before the operation, the other - during the rehabilitation and recovery of the body. Of course, at all stages of recovery, you must adhere to a balanced diet and lead a healthy lifestyle. Correctly selected foods enrich the body with nutrients, vitamins, essential trace elements, which favorably affect the regeneration of epithelial cells. This allows for a relatively short period of time to restore a flat surface and normalize the internal processes of the skin. But even after successful treatment it is advisable to visit the oncologist regularly to prevent the re-emergence of malignant processes. Especially it concerns those persons who are predisposed to cancer diseases (including skin cancer).
