Melanoma or skin cancer, symptoms

If we consider the statistics of development of cancerousillness, you can see that skin cancer is a common form of it and takes the third place in the number of cancer diseases. Most often, this disease affects people who have fair skin and hair, regardless of their sex. In this case, skin cancer, the symptoms of which appear in the pigmented lesions on the skin, includes three types of malignant tumors, the most common of which is melanoma.

Melanoma is one of the varieties of cancer, and is due to the non-stop division of skin cells that produce melanin.

It can be said that the first signs of skin cancerare manifested in the formation of new moles or in changing the size, color and shape of the existing ones. When these characteristics are detected, it is necessary to pay attention to such factors:

- asymmetry of the nevus;

- increase in the size of a birthmark;

- uneven edges of the pigmented spot;

- modification of the mole in the last few weeks;

- the appearance of new nevuses;

- the appearance of wounds that do not heal a long period.

Thus, skin cancer symptoms are pronounced, so it is easy to diagnose, which increases the success of timely treatment.

There are several diseases that are acceptedconsidered precancerous. This includes atrophy of the skin, keratomas and keratoacanthomas, posttraumatic scars, trophic and lupus ulcers, diseases of Paget and Bowen, pigment xeroderma and melanosis of Dubreia.

Causes of a disease such as cancerskin, to date have not been studied sufficiently. Certainly, there are some factors that provoke the formation of tumors, but what exactly causes cancer is unknown. One of the common causes of skin cancer is considered to be solar radiation or ultraviolet radiation. Therefore, melanoma is most affected by people who are in the sun for a long time.
So, skin cancer symptoms are as follows:

1. A sharp decrease in weight. This symptom can accompany a cancer disease regardless of its variety and form.

2. Increase body temperature. Most often observed when the spread of metastases.

3. The appearance of pain. Pain is a symptom of the spread of cancerous tumors throughout the body.

4. Changes in the skin. There are tumors on the skin, while the skin can change color or peel.

5. The appearance of non-healing wounds or ulcers on the skin. It can be a sign of the formation of a cancerous tumor that can bleed.

6. Change of the nevus. A mole can change color, shape, size and boundaries.

So, skin cancer, the symptoms of which are indicated above, withtime destroys the tissues, forming numerous ulcers on the skin. In frequent cases, melanoma spreads metastases to the skin, lungs, liver, bones and brain, this process depends on the severity of the disease and the thickness of the cancerous tumor. In the human skin spreads metastases of lung cancer and breast cancer.

It should be known that earlier detection of a tumortreatment makes effective, since the cancer disease has not yet metastasized into other organs and parts of the body. Conducting operations in this case is inevitable, which increases the likelihood of complete recovery.

It should be remembered that skin cancer symptoms canmanifest general, for example, in the form of rapid fatigue or an increase in body temperature. This is due to the fact that cancer cells secrete special substances that affect the metabolism in the human body.

Thus, it is necessary to carefully treat any changes or lesions on the skin, as this may indicate the development of such a terrible disease as cancer.
