Melanoma is one of the most deadly forms of skin cancer. It can be caused by prolonged exposure to ultraviolet radiation from the sun, tanning beds, and other sources. Early detection and treatment are critical for survival.
Here, we will provide an introduction to melanoma, including its causes, risk factors, signs and symptoms, diagnosis, and treatments. We’ll also discuss ways for people to reduce their risk of developing this serious form of skin cancer. With this information at hand, you can take steps to protect yourself or a loved one against melanoma.
History and Definition
Melanoma is a type of skin cancer that originates from melanocytes, the cells that produce the pigment melanin. It is a potentially life-threatening form of cancer that can spread to other parts of the body if not treated early.
The first recognition of melanoma as a distinct disease separate from other skin conditions can be traced back to 1804 when French physician Rene Laennec described it as melanose. In 1820, British physician William Norris observed the heterogeneous nature of some melanoma tumors. The term “melanoma” was officially introduced in 1838 by Sir Robert Carswell. Early detection and treatment are crucial for a positive outcome, so regular skin checks and monitoring of any changes in existing moles are important.
Symptoms
Melanoma symptoms may include:
- A change in the appearance of a mole, such as an increase in size, change in color, or irregular shape
- The development of a new mole
- Itching, tenderness, or pain in a mole
- A mole that bleeds or oozes
- A dark streak under a fingernail or toenail
- A patch of skin that is discolored and/or multi-dimensional
- A skin lesion with an irregular border
It is important to remember that not all melanomas have the same symptoms, and some may not have any symptoms at all. If you have concerns about a mole or spot on your skin, it is important to see a doctor. Early detection and treatment of melanoma greatly improve the chances of a successful outcome.
Causes
The exact cause of melanoma is not known, but several risk factors have been identified:
- Sun exposure: Prolonged exposure to ultraviolet (UV) radiation from the sun increases the risk of developing melanoma.
- Skin type: People with fair skin, light hair and eyes, and those who freckle easily are at higher risk.
- Family history: A family history of melanoma increases the risk of developing the disease.
- Moles: Having many moles or atypical moles can increase the risk of developing melanoma.
- Previous melanoma: Individuals who have had melanoma in the past are at an increased risk of developing another melanoma.
- Weak immune system: People with weakened immune systems are more susceptible to developing melanoma.
- UV light exposure: The use of tanning beds, which emit UV radiation, increases the risk of developing melanoma.
It is important to note that having one or more of these risk factors does not necessarily mean that a person will develop melanoma. The presence of these factors simply indicates an increased likelihood of developing the disease.
Diagnosis
Diagnosis of melanoma typically involves a skin examination and biopsy. The following steps are usually involved in the diagnosis process:
- Physical examination: A doctor will visually inspect the skin for any unusual moles or growths and check for changes in size, shape, color, or texture.
- Biopsy: If a suspicious mole or lesion is identified, a biopsy will be performed to remove a small sample of tissue for examination under a microscope. This is the only way to definitively diagnose melanoma.
- Pathologic analysis: The tissue sample is examined by a pathologist to determine whether the cells are cancerous and, if so, the type and severity of cancer.
In some cases, additional tests may be needed, such as a blood test to check for elevated levels of a protein produced by melanoma cells, or imaging tests, such as an MRI or CT scan, to check if cancer has spread to other parts of the body.
It is important to seek medical attention if you have concerns about a mole or spot on your skin, as early detection and treatment of melanoma can greatly improve the chances of a positive outcome.
Treatment
The treatments for melanoma include:
- Surgical excision: The most common treatment for melanoma is to surgically remove the tumor and some surrounding healthy tissue, this is called a wide local excision. If the melanoma is more advanced, a lymph node dissection may be performed.
- Immunotherapy: This treatment helps the body’s immune system fight cancer. There are different types of immunotherapy, including checkpoint inhibitors and vaccines.
- Radiation therapy: This uses high-energy beams to destroy cancer cells and shrink tumors. It may be used after surgery to reduce the risk of cancer returning.
- Chemotherapy: This treatment uses drugs to kill cancer cells. It may be used if the melanoma has spread to other parts of the body.
- Targeted therapy: This treatment uses drugs that target specific proteins or genetic changes in the cancer cells to slow or stop their growth.
What to expect after treatment for melanoma varies from person to person, depending on the type and extent of the treatment received. Side effects of treatment may include fatigue, pain, scarring, and skin changes. Close follow-up with a healthcare provider is necessary to monitor for recurrence and detect any new skin cancers early.
It is important to discuss the risks and benefits of each treatment option with a healthcare provider to make an informed decision. Early detection and prompt treatment are crucial for the best outcome in melanoma.
Risk Factors
There are several risk factors that can increase the likelihood of developing melanoma, including:
- Sun exposure: Prolonged exposure to ultraviolet (UV) radiation from the sun or tanning beds increases the risk of melanoma.
- Skin type: People with fair skin, light hair and eye color, and freckles are at higher risk for melanoma.
- Moles: Having a large number of moles, or moles that are irregular in shape or color, increases the risk of melanoma.
- Family history: People with a family history of melanoma have a higher risk of developing the disease.
- Previous melanoma: If someone has had melanoma in the past, they have an increased risk of developing it again.
- Suppressed immune system: People with weakened immune systems, such as those with HIV/AIDS or receiving immunosuppressive therapy, are at higher risk for melanoma.
- Sunburns: A history of severe or frequent sunburns, especially during childhood, increases the risk of melanoma.
It is important to protect the skin from UV radiation, perform regular self-exams to check for changes in moles and skin spots, and see a doctor if any changes are noticed. Early detection is crucial for the best outcome in melanoma.
Complications
Melanoma, if not detected and treated early, can lead to several complications, including:
- Spread to other parts of the body (metastasis): Melanoma can spread to other organs such as the lungs, liver, brain, and bones, making treatment more difficult and potentially reducing the chances of a cure.
- Lymph node involvement: Melanoma can spread to the lymph nodes, making them swollen and painful. This can also make it harder to treat melanoma effectively.
- Scarring: Surgical treatment for melanoma can result in scarring, especially if the cancer is located in a visible area such as the face or arms.
- Disfigurement: Some treatments for melanoma, such as surgery or radiation therapy, can result in disfigurements, such as changes in skin color or texture.
- Emotional impact: A diagnosis of melanoma can cause significant stress and anxiety, and can impact a person’s quality of life.
- Recurrence: Despite treatment, melanoma can sometimes recur, requiring additional treatment and follow-up.
It is important to work closely with a healthcare provider to manage any complications of melanoma and to monitor for recurrence. Prompt treatment and early detection can help reduce the risk of these complications and improve the chances of a cure.
When to See a Doctor
It is important to see a doctor if you notice any changes in your skin, including the appearance of a new mole or a change in the size, shape, color, or texture of an existing mole. It is especially important to seek medical attention if you notice the following ABCDE warning signs of melanoma:
- Asymmetry: One half of the mole does not match the other.
- Border: The edges of the mole are irregular or not well-defined.
- Color: The color of the mole is not uniform and may contain shades of black, brown, or multiple colors.
- Diameter: The mole is larger than 6 millimeters (about the size of a pencil eraser) or growing in size.
- Evolution: The mole has changed in appearance over time.
It is also important to see a doctor if you experience any symptoms such as itching, bleeding, or pain in or around a mole. Early detection and prompt treatment are crucial for the best outcome in melanoma.
