If we consider the statistics of the development of cancer, we can see that skin cancer is a common form of it and ranks third among oncological diseases. Most often, this disease affects people who have fair skin and hair, regardless of their gender. At the same time , skin cancer, the symptoms of which are manifested in 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 occurs as a result of non-stop division of skin cells that produce melanin.
We can say that the first signs of skin cancer are manifested in the formation of new moles or in the change in the size, color and shape of existing ones. When these signs are detected, it is necessary to pay attention to such factors:
- asymmetry of the nevus;
- an increase in the size of a mole;
- uneven edges of the pigment spot;
- Modification of a mole in the last few weeks;
- the emergence of new nevi;
- the appearance of wounds that do not heal for a long period.
Thus, skin cancer has pronounced signs, so it is not difficult to diagnose, which increases the success of timely treatment.
There are several diseases that are considered precancerous. These include skin atrophy , keratomas and keratoacanthomas, post-traumatic scars, trophic and lupus ulcers, Paget and Bowen diseases , xeroderma pigmentosa and Dubreus melanosis.
The causes of the appearance of a disease such as skin cancer have not been adequately studied to date. Of course, there are some factors that provoke the formation of tumors, however, what exactly causes cancer is unknown. One of the common causes of skin cancer is solar radiation or ultraviolet radiation. Therefore, melanoma is most affected by people who have been in the sun for a long time.
So, skin cancer symptoms are as follows:
1. Dramatic weight loss. This symptom can accompany cancer, regardless of its variety and form.
2. An increase in body temperature. Most often observed with 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. Tumors occur on the skin, while the skin can change color or peel off.
5. The appearance of non-healing wounds or ulcers on the skin. May be a sign of cancer that may bleed.
6. Change in nevus. A mole can change color, shape, size, and border.
So, skin cancer, the symptoms of which are indicated above, eventually destroys 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. Lung cancer and breast cancer spread metastases to human skin.
You should be aware that earlier detection of a tumor makes the treatment effective, since the cancer has not yet metastasized to other organs and parts of the body. Operations in this case are inevitable, which increases the likelihood of a full recovery.
It must be remembered that skin cancer symptoms may manifest common, 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 be attentive to any changes or neoplasms on the skin, as this may indicate the development of such a terrible disease as cancer.
