The Basis of successful treatment of the disease — timely diagnosis. Especially this statement is justified in tumor pathologies, when literally every second counts. One of such problems is melanoma. Every year is cancer only younger. The earlier a doctor will be able to identify it, the higher the chances of a favorable prognosis. In today's article a closer look at the main methods of melanoma diagnosis, as well as tell you about options for her treatment.

Medical reference

Melanoma is the malignant nature of the neoplasm that develops in the skin tissue fragments. It is formed from melanocytes-cells responsible for the secretion of pigment by reproduction of the item. The most vulnerable are those areas of the body that are difficult to protect from ultraviolet radiation. We are talking about the face, torso and limbs. Melanoma can form at the site of a previously existing nevus or spread on a perfectly healthy epithelial fragments.diagnosis of melanoma

An Important feature of the pathological process is the almost complete absence of an immune response. Therefore, the tumor rapidly develops and increases in size. Every year it is diagnosed in approximately 100 thousand people. In our country there is a tendency to growth of diseases. While melanoma most often affects people aged 75 to 85 years. It significantly reduces life expectancy and can lead to death.

According to medical statistics, approximately 75% of cases it is possible to detect this disease at an early stage of development. It is possible not only because of the severe clinical picture. A role in the process of identification belongs to the early diagnosis of melanoma. To distinguish it from other types of skin cancers can be visually. However, for drawing up treatment programs need to know about the tumor the maximum amount of information. Diagnostics allows to determine the degree and stage of pathological process, predict, find, metastases, etc. Further detail will focus on main options.

History

History — is the primary phase diagnosis of almost all pathologies. It refers to the study of the history of the patient and the collection of information. According to the results of the original survey specialist will be able to make the preliminary diagnosis and the taking into account of the conclusion to appoint further examination.

Deals with a Melanoma oncologist. At the first appointment he's definitely questioning the patient about his disturbing symptoms. To clarify the clinical picture, the oncologist may ask a number of clarifying questions: when were the focus of inflammation, which factors preceded his development, etc.

Diagnosis of melanomas also involves the study of genetic predisposition. Doctor it is important to know whether cases of this disease in other family members. The fact is that most of cancer has a hereditary character.diagnosis of melanoma

Physical examination

In the course of a detailed study of the clinical manifestations of the tumor, the specialist will provide a qualitative assessment of its basic parameters:

  • Size;
  • Structural content;
  • Bounds;
  • Color pigment;
  • Surface textures.

Also, the doctor performs palpation of inguinal, axillary and cervical lymph nodes. If melanoma metastasizes, it is the pathological lesions primarily spread to adjacent lymph nodes. Increase in size — a clear symptom of cancer.

If you suspect a malignant cancer diagnosis the obligatory condition is the study and examination of other parts of the body where you may have the same items. About their availability, many patients are not even aware. As a secondary neoplasm, the seal may not manifest certain symptoms or do not disturb. Multiple pathological foci — the specific feature of this form of cancer.diagnosis of melanoma

Dermatoscopy

This is another non-invasive method for the diagnosis of melanoma. It is absolutely painless, so afraid of medical procedures is not necessary.

During the procedure, the doctor gets information on the thickness of the tumor, determine its size with a special tool — a micrometer. Research exposed of even a small education, the value of which is not more than 1 mm.

Analysis of venous and capillary blood

Blood can learn a lot about the state of the body. All cancer cells produce specific proteins. This so-called tumor markers. In a healthy person they do not exist.

In the case of melanoma in the laboratory determine the sensitivity to a protein tumor marker S-100. Its high concentration in the blood indicates not only correct preliminary diagnosis, but the progression of the pathological process. We are talking about the presence in the body of the metastases, lesions of other internal organs. At the treatment stage with the help of this analysis, the doctor checks the correctnessthe chosen tactics of treatment, the degree of its effectiveness.

In our country the diagnosis of melanoma by determining the blood concentration of tumor markers is carried out only for a fee. The cost of inspection is high enough, which is justified by the almost 100 % accurate result. diagnosis of melanoma reviews

Use of radioactive phosphorus

Differential diagnosis of melanoma is carried out using a reactive phosphorus. It is based on the exposure to the pathological focus dwuzameshchenny sodium phosphate, marked with radioactive phosphorus component. Patient doctor suggests to drink in the morning and always on an empty stomach. Then through the contact radiometry is determined by the concentration of isotopes in the area of localization of the seal. Level "criterion of malignancy” for melanoma is considered a threefold excess accumulation of the isotope over the tumor, if to compare this figure with the area of healthy skin.

Microscopy, confocal

This option is a non-invasive diagnosis of melanoma enables you to identify the problem at an early stage of its development. Is performed using confocal microscopic apparatus with a small concentration of the infrared radiation flow. Used the radiation dose is negligible, so it can not harm the human body. The microscope investigates the external and internal epithelial layers, and is even considered an improved version of the virtual biopsy.

CT and MRI

An Important step in the fight against any cancer is early detection of metastases. The fact is that the distribution of lesions throughout the body often increases the likelihood of recurrence and eliminates the forecast on a speedy recovery. With this purpose, the currently used MRI and CT scan.

Magnetic resonance imaging is based on the use of strong magnets and radioactive wave flows. Through this it is possible to obtain the image in the longitudinal and transverse position. Computed tomography can also reveal the presence of metastasis. However, to her aid is usually resorted to at the stage of assumptions when the fact of dissemination of lesions throughout the body is not yet confirmed.melanoma in the clinic diagnosis treatment

Biopsy

At an early stage melanoma is difficult to recognize visually. The biopsy enables study of the elements of the neoplasm and to determine the degree of malignancy. During the procedure, the doctor extracts the tumor cells and then examines them under a microscope. It is sometimes necessary to remove a suspicious area of skin completely.

If malignancy is confirmed, will be removed not only melanoma, but also a nearby tissue. When its thickness exceeds 1 mm, be sure to carry out excision of the patrol nodes. Such formations have a tendency to metastasize. The pathological process begins in sentry nodes. They also undergo study under the microscope. If the cancer specialist items they do not find the diagnostics of the lymphatic system is concerned. Otherwise, appoint additional methods of treatment (e.g. chemotherapy).differential diagnosis of melanoma

Self-recognition of disease

Method of self-diagnosis of skin melanoma cannot be considered a reliable way of detecting the disease. On the other hand, do not take note of it and not worth it. Continuous monitoring of health status increases the probability of timely detection of problems.

Recognize cancer the following symptoms:

  1. The Appearance of new pigment spots or moles on your body.
  2. Change the colour of the nevus, itching.
  3. The Discoloration of pigment — a characteristic feature of cell mutation.
  4. To change the borders of the mole. They can lose its former clarity, and become blurry and uneven.

Early diagnosis of melanoma is the key to successful treatment. Therefore, if you receive one or more of the symptoms listed above should immediately seek assistance from a dermatologist. If the family has already been diagnosed cases of the disease, it is necessary with special attention to the condition of the skin.

Patients

Talking to real patients about the diagnosis of melanoma? Reviews about this procedure there are different. In our article lists only the most common methods of detecting pathology. The choice of the particular survey is always the doctor.

Positive feedback associated with non-invasive techniques. Patients do not feel discomfort, and the procedure is absolutely painless. However, they are informative only at the initial stage of pathology development.

Negative opinions usually occur after a biopsy. Indeed, this is a unpleasant procedure, performed under anesthesia. On the other hand, it is possible to reliably determine the degree of malignancy.

Recommended treatment

Diagnosis and treatment of melanoma should not be ignored. After confirmation of the neoplasm is necessary to immediately begin treatment. Tactics of treatment depends onstage of the pathological process. For example, early surgery performed. During surgery, the doctor removes the melanoma, the surrounding at a distance of 1-3 cm of tissue and subcutaneous fat. The method of cryoablation in this condition is not applicable.

If you have been identified metastases after treatment in the clinic to diagnose melanoma, treatment is to carry out irradiation and chemotherapeutic agents (“Home”, “Carmustin”). It is toxic enough money, but without using them is not enough. Parallel to compulsory immunotherapy. diagnosis and treatment of melanoma

How to prevent disease?

Prevention of any cancer lies in its timely detection. International day of diagnosis of melanoma annually on 23 may. On the territory of our country in most cities, he pays a lot of attention. For example, in this day you can take a free checkup of moles and nevi on the body, to know the degree of malignancy. In addition, in many specialized medical centers, meetings with doctors and specialists who talk about this disease and answer questions from the audience.

Independently prevent the development of melanoma is not easy. The doctors call in the summer, use of protective agents for the skin, which prevent the penetration of UV rays. From sunbathing should be abandoned in the period from 12 to 16 hours. Must be attentive to yourself. Quite easy to periodically examine the body, identify new lesions on the skin and monitor the status of existing moles.

If you are in doubt it is better to visit an oncologist or dermatologist. Also do not forget that on may 23-the day of diagnosis of melanoma, when we can all get a free screening. According to the results only when necessary our specialist will always be sent for further examination.
