Melanoma is one of the most common and dangerous types of skin cancer; it may be fatal if not treated at an early stage. Melanomas are usually similar to moles, and sometimes are caused by moles. Even though they are mostly black and brown, they can sometimes be pink, red, purple, blue or even white. Although it can develop anywhere on the skin, it is seen more intensely in the chest and back in males and in the legs in females. They may also develop in the neck, face, eye, mouth, genital area or even in the anal region. Factors such as exposure to harmful rays of the sun, solarium and light skin color, although mostly genetic, also trigger melanoma. Symptoms are asymmetric, unclear, pink, blue, moles or lesions that can be of different colors. In the treatment of early melanoma, surgical intervention is generally used and tumor tissues are removed; the success rate is very high.

What is melanoma?

Melanoma is dangerous types of skin cancer and easily spread to other organs. It usually starts in a skin cell and the most common cause of death, even if it is not common among skin cancers. Melanoma, also called malignant melanoma or cutaneous melanoma, begins in melanocytes. Melanocytes are the cells producing melanin, which can be turned into melanoma in the following process and gives color to the skin, is the cells that make brown pigments. Melanocytes are located in the epidermis, the upper layer of the skin.

In addition to giving the skin its brown color, the melanin protect the lower layers of the skin against harmful effects of the sun. When skin is exposed to sun for a long time, melanocytes produce more amounts of melanin and skin becomes tanned and darkened.

Since melanoma cells continue to produce melanin, melanoma tumors are brown or black in many patients. In cancer patients whose melanin production stopped, tumors may be pink, brown or even white.

Causes of melanoma

  • The main cause of melanoma is abnormal melanocyte skin cells
  • Malignant melanoma usually develops from moles (nevus).
  • Long-term exposure to UVA and UVB rays during sunbathing or solarium
  • Non-normal (atypical) moles found in the skin
  • Having fair eye and skin color and a sensitive skin type
  • Have previously had melanoma
  • The weakening of the immune system due to organ transplants, chemotherapy, AIDS, lymphoma
  • Having a melanoma in a family history

Symptoms of melanoma

  • Asymmetry: The moles in the skin are asymmetric and they are not alike.
  • Boundary: The boundaries of the moles are unclear, the edges are scalloped and notched.
  • Color: Melanoma can be red, white, pink, black, skin color or brown.
  • Diameter: Size of moles, diameter is large. It is usually more than 6 mm (as much as chickpea).
  • Expansion: Cancerous moles expand and grow.

The moles in the skin are usually harmless. Symptoms are usually seen in one or two moles in the early stages, quite different from the other ones. To distinguish these symptoms ABCDE (Asymmetry, Border, Color, Diameter and Evolving) rule is used.

When there is enlargement, size, shape, discoloration, bleeding, itching, crusting, consult a doctor immediately.

Melanoma types

Melanoma is divided into different groups according to the shape and characteristics of the moles.

Melanoma spreading on the surface

It is more common in people with freckled and pale skin. The moles usually grow outward and their borders are irregular. When they go down to the deeper layers of the body, they have the risk of spreading to other organs.

Nodular melanoma

They grow very quickly and can even go down to the lowest layers of the skin. Melanomas, which may be red, grow on normal skin. They are mostly seen in the head, neck, back and chest. They are evident by bleeding and leakage.

Lentigo malignant melanoma

It is one of 10 cases of melanoma. It is mostly seen in the elderly who are very exposed to the sun. They are larger and darker than the freckles. At first, the flat moles can gradually grow and change over time. Over the years, they can form the nodules by growing down to the lower layer of the skin.

Acral lentigous melanoma

A rare form of melanoma seen on the hands and feet. Sometimes they can develop around the nail. Although it is more common in dark-skinned people, it can also be seen in fair skinned or haired people.

Amelanotic melanoma

In this rare melanoma, moles may be pink, red, gray, brown, sometimes colorless.

Melanoma cancer stages

The stage of a cancer expresses how far the cancer has spread. Doctors plan the treatment process according to the stage of cancer. The stages of melanoma are between 0-4.

  • In stage 0, cancer is only in the outermost layer of the skin and is generally non-hazardous.
  • In stage 1, the tumor is thinner than 2 mm, and may be ulcerated or non-ulcerated.
  • Although cancer cells that may be ulcerated or non-ulcerated in stage 2 may be thicker than 4 mm, they have not yet spread to surrounding tissues.
  • In Stage 3, the cancer that spreads to the surrounding tissues does not spread to distant tissues and organs.
  • In the 4th most dangerous phase, the cancer spread to nearby lymph nodes and spread to very important distant organs such as the lung, liver and brain.

Diagnosis of melanoma cancer

For diagnosis of melanoma, firstly, you are asked about your medical history and moles in your skin are examined. If there is a suspicious condition, a biopsy is performed. The mole removed by a surgical intervention, and is examined closely to find whether it is melanoma. In addition, it can be checked whether the melanoma is spread to nearby tissues by the Sentinal node biopsy.

Skin examine is important for diagnosis of melanoma

Shave (tangential) biopsy, punch biopsy, Incisional and excisional biopsies reflectance confocal microscopy, sentinel lymph node biopsy are among the types of biopsies frequently used in the diagnosis of melanoma.

Treatment of malignant melanoma cancer

Treatment of the disease usually depends on the stage of the melanoma. In cases where melanoma is diagnosed early, fatal consequences that caused by cancer can be prevented. Surgical intervention is usually preferred in the treatment of early cancer. In advanced stages, drugs that inhibit the spread of cancer cells, such as BRAF inhibitors, can be prescribed.

Malignant melanoma surgery

In most cases, thin melanomas are removed under local anesthesia. Postoperative small scars will heal spontaneously over time. The surgical excision is used to treat all skin cancer types. Although the wounds usually heal 1-2 weeks after the procedure, this period depends on the patient completing the wound care completely.

Microscopic surgery

Recently, as an alternative to excision, microscopic surgery is a preferred method. With this method, a thin tissue is removed from the melanoma and cancer cells are examined under a microscope. The removal of the tissues continues until all cancerous cells are completely removed. The method is different from other surgical methods because it shows how deep the cancer cells are.

Immunotherapy

Immunotherapy can be used in the 3rd and 4th stages of melanoma cancer, in which cancer cells progress deeply or spread to distant organs. Drugs injected intravenously into the patient can significantly extend the patient’s life expectancy.

Targeted treatments

With targeted therapies, certain cancer cells in stage 3 and 4 are identified and these cells that are effective in the spread of cancer are blocked.

Chemotherapy

Today, although targeted therapy and immunotherapy are more used in the treatment of melanoma, chemotherapy may also be used in the treatment of the 3rd and 4th stage melanoma in addition to these therapies.

Radiation therapy

As with other types of skin cancer, radiation therapy may be necessary in addition to chemotherapy drugs for advanced melanoma treatment. High-energy X-rays with external beam radiation therapy focus on tumors in the epidermis layer of the body. With radiation therapy used in the treatment of the 3rd and 4th stage melanoma, the spread of melanoma to the brain and the growth of the tumor can be stopped.

Early stage melanoma, which has not reached the 3rd and 4th stages, can often be treated. However, risk of death is high in patients with 3th and 4th advanced melanoma.

Although life expectancy of the 4th stage patients is extended by non-surgical methods for a few months and sometimes for a few years, it is unfortunately not possible to get rid of the disease completely. Therefore, early diagnosis of the disease is extremely important.

Herbal treatment of melanoma

Some plants can be used to prevent the spread of cancer cells or to prevent cancer in the early stage of skin cancer. These treatments, however, cannot replace surgical treatment or medication in any way. Always consult your doctor before you try herbal treatment methods.

Red beet

You can fight melanoma by adding red beet to your nutrition program which contains substances that prevent the spread of cancer in its components. Red beet can be consumed by raw or squeezing water.

Green leafy vegetables

You can reduce your risk of getting melanoma by eating lycopene-containing foods frequently such as tomato, as well as green leafy vegetables such as spinach, leek, which help the body to fight the cancer cells by strengthening the immune system, which also significantly increase the body’s beta-carotene needs.

Skin cancer and melanoma protection methods

  • Periodically check the moles in your skin.
  • Be careful not to go out between hours 10:00-16:00, especially when the UV rays are the most harmful in summer months.
  • Make sure that the sun protection creams you use protect against UVB and UVA rays.
  • If you have a light skin color, blond hair, red hair and you are freckled; use sun protection creams with a protection factor of at least 30%.
  • Apply sun protection cream to your skin at least 30 minutes before you go out.
  • Use sun protection cream even when you are in your home, in car or at shade. Note that UVB rays may even penetrate through the windows.
  • Apply sun protection creams in every two hours.
  • Avoid sunbathing on deckchairs, especially if you have a skin that is pale, thin and skin has too much moles

Melanoma in childhood

Although the likelihood of melanoma in children is extremely low, it is not impossible. Melanoma is the second most common cause of skin cancer in children. Children with sunburn, especially on skin, are at risk.

Precautions we can take to protect children:

  • Apply sun protection creams having +15 more protection percentage to children before sun exposure.
  • Do not expose babies between 0-6 months to direct sunlight.
  • Cover car windows with UV films
  • Use a stroller with sun protection.
  • Do not take your baby out between 10 am and 4 pm.
