About cutaneous malignant melanoma, hereditary
What is cutaneous malignant melanoma, hereditary?
Atypical mole syndrome, also called dysplastic nevus syndrome, is a disorder of the skin characterized by the presence of many mole-like tumors (nevi). Most people have 10-20 moles over their bodies. People with this syndrome often have more than 100 moles, at least some of which are unusual (atypical) in size and structure. These moles vary in size, location, and coloring. They are usually larger than normal moles (5mm or more in diameter) and have irregular borders. Changes in the appearance of these moles must be taken seriously by patients since such changes may foreshadow the onset of cancerous disease.
Individuals with atypical mole syndrome are at greater than others for developing cancer of the skin in the form of malignant melanoma. Atypical mole syndrome is thought by some clinicians to be a precursor or forerunner of malignant melanoma. This type of cancer may spread to adjacent parts of the skin or, through the blood and lymph circulation, to other organs.
What are the symptoms for cutaneous malignant melanoma, hereditary?
Moles are usually harmless. They may contain hairs or become raised or wrinkled. Talk to your doctor about any change in the color or size of a mole or if itching, pain, bleeding or Inflammation develops.
The first sign of melanoma is often a mole that changes size, shape or color. This melanoma shows color variations and an irregular border, both of which are melanoma warning signs.
Melanomas can develop anywhere on your body. They most often develop in areas that have had exposure to the sun, such as your back, legs, arms and face.
Melanomas can also occur in areas that don't receive much sun exposure, such as the soles of your feet, palms of your hands and fingernail beds. These hidden melanomas are more common in people with darker skin.
The first melanoma signs and symptoms often are:
- A change in an existing mole
- The development of a new pigmented or unusual-looking growth on your skin
Melanoma doesn't always begin as a mole. It can also occur on otherwise normal-appearing skin.
Normal Moles are generally a uniform color — such as tan, brown or — with a distinct border separating the mole from your surrounding skin. They're oval or round and usually smaller than 1/4 inch (about 6 millimeters) in diameter — the size of a pencil eraser.
Most Moles begin appearing in childhood and new Moles may form until about age 40. By the time they are adults, most people have between 10 and 40 moles. Moles may change in appearance over time and some may even disappear with age.
Unusual Moles that may indicate melanoma
To help you identify characteristics of unusual Moles that may indicate melanomas or other skin cancers, think of the letters ABCDE:
- A is for asymmetrical shape. Look for Moles with irregular shapes, such as two very different-looking halves.
- B is for irregular border. Look for Moles with irregular, notched or scalloped borders — characteristics of melanomas.
- C is for changes in color. Look for growths that have many colors or an uneven distribution of color.
- D is for diameter. Look for new growth in a mole larger than 1/4 inch (about 6 millimeters).
- E is for evolving. Look for changes over time, such as a mole that grows in size or that changes color or shape. Moles may also evolve to develop new signs and symptoms, such as new itchiness or bleeding.
Cancerous (malignant) Moles vary greatly in appearance. Some may show all of the changes listed above, while others may have only one or two unusual characteristics.
Melanomas can also develop in areas of your body that have little or no exposure to the sun, such as the spaces between your toes and on your palms, soles, scalp or genitals. These are sometimes referred to as hidden melanomas because they occur in places most people wouldn't think to check. When melanoma occurs in people with darker skin, it's more likely to occur in a hidden area.
Hidden melanomas include:
- Melanoma under a nail. Acral-lentiginous melanoma is a rare form of melanoma that can occur under a fingernail or toenail. It can also be found on the palms of the hands or the soles of the feet. It's more common in people of Asian descent, people and in others with dark skin pigment.
- Melanoma in the mouth, digestive tract, urinary tract or vagina. Mucosal melanoma develops in the mucous membrane that lines the nose, mouth, esophagus, anus, urinary tract and vagina. Mucosal melanomas are especially difficult to detect because they can easily be mistaken for other far more common conditions.
- Melanoma in the eye. Eye melanoma, also called ocular melanoma, most often occurs in the uvea — the layer beneath the white of the eye (sclera). An eye melanoma may cause vision changes and may be diagnosed during an eye exam.
What are the causes for cutaneous malignant melanoma, hereditary?
Where skin cancer develops
Skin cancer begins in the cells that make up the outer layer (epidermis) of your skin. One type of skin cancer called basal cell carcinoma begins in the basal cells, which make skin cells that continuously push older cells toward the surface. As new cells move upward, they become flattened squamous cells, where a skin cancer called squamous cell carcinoma can occur. Melanoma, another type of skin cancer, arises in the pigment cells (melanocytes).
Melanoma occurs when something goes wrong in the melanin-producing cells (melanocytes) that give color to your skin.
Normally, skin cells develop in a controlled and orderly way — healthy new cells push older cells toward your skin's surface, where they die and eventually fall off. But when some cells develop DNA damage, new cells may begin to grow out of control and can eventually form a mass of cancerous cells.
Just what damages DNA in skin cells and how this leads to melanoma isn't clear. It's likely that a combination of factors, including environmental and genetic factors, causes melanoma. Still, doctors believe exposure to ultraviolet (UV) radiation from the sun and from tanning lamps and beds is the leading cause of melanoma.
UV light doesn't cause all melanomas, especially those that occur in places on your body that don't receive exposure to sunlight. This indicates that other factors may contribute to your risk of melanoma.
What are the treatments for cutaneous malignant melanoma, hereditary?
The best treatment for your melanoma depends on the size and stage of cancer, your overall health, and your personal preferences.
Treatment for small melanomas
Treatment for early-stage melanomas usually includes surgery to remove the melanoma. A very thin melanoma may be removed entirely during the biopsy and require no further treatment. Otherwise, your surgeon will remove the cancer as well as a border of normal skin and a layer of tissue beneath the skin. For people with early-stage melanomas, this may be the only treatment needed.
Treating melanomas that have spread beyond the skin
If melanoma has spread beyond the skin, treatment options may include:
- Surgery to remove affected lymph nodes. If melanoma has spread to nearby lymph nodes, your surgeon may remove the affected nodes. Additional treatments before or after surgery also may be recommended.
Immunotherapy. Immunotherapy is a drug treatment that helps your immune system to fight cancer. Your body's disease-fighting immune system might not attack cancer because the cancer cells produce proteins that help them hide from the immune system cells. Immunotherapy works by interfering with that process.
Immunotherapy is often recommended after surgery for melanoma that has spread to the lymph nodes or to other areas of the body. When melanoma can't be removed completely with surgery, immunotherapy treatments might be injected directly into the melanoma.
Targeted therapy. Targeted drug treatments focus on specific weaknesses present within cancer cells. By targeting these weaknesses, targeted drug treatments can cause cancer cells to die. Cells from your melanoma may be tested to see if targeted therapy is likely to be effective against your cancer.
For melanoma, targeted therapy might be recommended if the cancer has spread to your lymph nodes or to other areas of your body.
Radiation therapy. This treatment uses high-powered energy beams, such as X-rays and protons, to kill cancer cells. Radiation therapy may be directed to the lymph nodes if the melanoma has spread there. Radiation therapy can also be used to treat melanomas that can't be removed completely with surgery.
For melanoma that spreads to other areas of the body, radiation therapy can help relieve symptoms.
Chemotherapy. Chemotherapy uses drugs to kill cancer cells. Chemotherapy can be given intravenously, in pill form or both so that it travels throughout your body.
Chemotherapy can also be given in a vein in your arm or leg in a procedure called isolated limb perfusion. During this procedure, blood in your arm or leg isn't allowed to travel to other areas of your body for a short time so that the chemotherapy drugs travel directly to the area around the melanoma and don't affect other parts of your body.
What are the risk factors for cutaneous malignant melanoma, hereditary?
Factors that may increase your risk of melanoma include:
- Fair skin. Having less pigment (melanin) in your skin means you have less protection from damaging UV radiation. If you have blond or red hair, light-colored eyes, and freckle or sunburn easily, you're more likely to develop melanoma than is someone with a darker complexion. But melanoma can develop in people with darker complexions, including Hispanic people and people.
- A history of sunburn. One or more severe, blistering sunburns can increase your risk of melanoma.
- Excessive ultraviolet (UV) light exposure. Exposure to UV radiation, which comes from the sun and from tanning lights and beds, can increase the risk of skin cancer, including melanoma.
- Living closer to the equator or at a higher elevation. People living closer to the earth's equator, where the sun's rays are more direct, experience higher amounts of UV radiation than do those living farther north or south. In addition, if you live at a high elevation, you're exposed to more UV radiation.
- Having many moles or unusual moles. Having more than 50 ordinary moles on your body indicates an increased risk of melanoma. Also, having an unusual type of mole increases the risk of melanoma. Known medically as dysplastic nevi, these tend to be larger than normal moles and have irregular borders and a mixture of colors.
- A family history of melanoma. If a close relative — such as a parent, child or sibling — has had melanoma, you have a greater chance of developing a melanoma, too.
- Weakened immune system. People with weakened immune systems have an increased risk of melanoma and other skin cancers. Your immune system may be impaired if you take medicine to suppress the immune system, such as after an organ transplant, or if you have a disease that impairs the immune system, such as AIDS.
Is there a cure/medications for cutaneous malignant melanoma, hereditary?
Cutaneous Malignant Melanoma, hereditary, is also named dysplastic nevus syndrome. It is atypical mole syndrome. It is a skin disorder. There appears to be the presence of mole-like tumors on the skin, near about more than 100 moles over the body, which are atypical in size and structure. There can be any size, color or location of the moles.
The normal moles are of the size of 5mm or more in diameter, but if there appear to be any changes in this, then it should be taken seriously and should consult a doctor immediately because it may be a cancerous disease. Melanoma develops anywhere on the body, such as the back, legs, arms, face, soles of feet, palms of hands, and fingernail beds. There is also hidden melanoma under a nail, in the mouth, digestive tract, urinary tract, vagina, and eye. People who are at risk are those who have a history of sunburn, excessive ultraviolet light exposure, having many moles, a family history of melanoma, weakened immune system etc.
Cure/medications for cutaneous malignant melanoma, hereditary:
1. Generally, treatment may depend on the size and stage of cancer. Surgery is done to remove the thin melanoma.
2. If surgery cannot remove it, then Immunotherapy works. It helps the immune system to fight cancer.
3. Targeted therapy can be done if cancer has spread to lymph nodes or to other areas of the body.
4. Radiation therapy helps in removing melanomas completely. Chemotherapy is also done to kill cancer cells. Antiviral drugs are prescribed to reduce the virus's ability to replicate.
