Many people regularly check their skin for changes, which can be oncology. But not all moles, spots or rashes are skin cancer. In this article we will discuss the differences between seborrheic keratosis and skin cancer.
Seborrheic keratoses - this is not a cancer but it can strongly resemble melanoma. In the US alone, about 83 million people have a seborrheic keratosis.
About 5 percent of all new cancer cases in the United States are melanoma, a potentially fatal form of skin cancer . The surgical treatment of melanoma more than 91% of patients survive 5 years or more after the initial diagnosis of melanoma in Israel .
Seborrheic keratosis or melanoma
Seborrheic keratoses may look like melanoma, but is not a skin cancer.
Seborrheic keratoses - a harmless growths / inflammation of the skin that often appear with age. Some people have only one, but as a rule, several such places are formed on the body. Seborrheic keratosis is not a risk factor for developing skin cancer or precancerous lesions form.
Seborrheic keratoses are often brown and spotted, and can appear anywhere on the body. Growths may look waxy, as if they were painted on the body. Some people initially take them to the unusually-looking scabs.
Seborrheic keratoses usually do not cause symptoms, but some people do not like the way they look.
Sometimes they become inflamed or irritated, causing pain and itching. Damage seborrheic keratosis can cause infection.
Melanoma - a type of skin cancer that can start as a birthmark or wart. It kills more people than any other form of skin cancer and can spread to other areas of the body (metastasize).
In some people, melanoma can look like seborrheic keratoses. People with a history of seborrheic keratosis may not notice a melanoma in its early stages, when they are used to unusual skin spots.
Melanoma and seborrheic keratoses is not easy to distinguish, but a dermatologist can determine the difference based on the physical examination. In some cases, however, it is necessary to conduct a biopsy to check the cancer under the microscope.
The causes of seborrheic keratosis
Doctors do not know what causes seborrheic keratoses, and can reduce the risk of these skin growths. They are not contagious and does not spread from contact. Some people notice that the build-up, as a general rule, apply to the skin over time.
The primary risk factor is age. Some studies show that exposure to sunlight may increase the chances of developing seborrheic keratoses.
Other risk factors include:
- skin irritation and friction, for example, in skin folds, especially in people who already have a seborrheic keratosis;
- viruses, such as human papillomavirus (HPV);
- genetic mutations;
- family history of seborrheic keratosis;
- Some drugs, such as inhibitors of the epidermal growth factor receptor.
Causes of melanoma
The presence of light skin and hair is a factor in the risk of melanoma.
Over time, the ultraviolet (UV) radiation from the sun or tanning beds can change the behavior of the skin. This can lead to skin cancer, including melanoma.
Although exposure to the sun is one of the most important risk factors for melanoma, other factors also play a role.
Risk factors for melanoma include:
- multiple moles, especially if the moles are unusual;
- possession of fair skin, light eyes and blond hair;
- own history of melanoma or other skin cancers;
- a weak immune system due to HIV or AIDS, chemotherapy, certain medications, and some diseases;
- family history of melanoma;
- genetic mutation that increases the risk of melanoma;
- birthmarks, izmenyayuviesya over time.
Diagnosis of melanoma in Israel
Often the specialist can distinguish melanoma from seborrheic keratoses by visual inspection. When the doctor is not sure of the diagnosis, or if a person has a number of risk factors for melanoma, a biopsy may be required.
Seborrheic keratoses are usually:
Melanoma tends to change and grow over time, so anyone who has a spot or wart-like seborrheic keratoses, but that changes in the shape or color should refer to a specialist.

- Symmetry: spot or mole vygladyaschie differently on both sides;
- Outlines: irregular border or the border with jagged edges;

If seborrheic keratosis is damaged or infected, it may be necessary to remove.
Doctors can remove seborrheic keratoses, using one of a number of minor surgical procedures. The most popular method - to freeze the wart. The physician may decide to cut outgrowth of skin or use a process called elektrodiskkatsiey which involves the use of electrical current to remove the growth.
Melanoma Treatment in Israel

However, therapy is almost always requires the removal of the cancer, as well as any lymph nodes to which it has spread.

- immunotherapy - the type of therapy that uses the body's immune system to fight cancer;
- targeted therapy.

The doctor or dermatologist should be able to identify a seborrheic keratosis of the visual inspection.
Seborrheic keratosis and melanoma can appear in many forms. People concerned about the growth of the skin, should not try to self-diagnose their condition and should not be assumed that the new skin growth is benign.
You need to see a specialist, if you are developing new skin growths, especially if over time there is a change or have a family history of skin cancer.
People with seborrheic keratosis should undergo regular skin checks. This reduces the likelihood of errors when melanoma is taken as seborrheic keratosis. Watching a specialist once a year to check the skin and moles, you reduce the risk of developing advanced forms of skin cancer.
