Melanoma is a form of skin cancer in which abnormal skin cells grow out of control. It helps to learn about this condition and what can be done about it.
It is very important for you to take good care of your skin so that you don't get melanoma. If you've had melanoma, protect your skin from the sun to lower your risk of getting it again. And if you've had treatment for melanoma, you will need regular checkups with your doctor to make sure it hasn't come back.
Melanoma shows up mostly on skin that is not regularly covered up. But it can show up anywhere on the body. It is most often found early, when it can be cured. The most common treatment is surgery to remove it. Sometimes lymph nodes near the cancer also are removed. Other treatments for melanoma may include medicines that target cancer cells (targeted therapy) and medicines that help your immune system fight cancer (immunotherapy). In some cases, radiation therapy or chemotherapy may be used.
Melanoma is the most serious type of skin cancer. It starts when the pigment-producing cells in your skin (melanocytes) become abnormal and grow out of control.
Melanoma usually looks like a flat, brown or black mole that has irregular, uneven borders. Most melanomas show up as a new spot or skin growth. But they can form in an existing mole or other mark on the skin. Less often, melanoma begins in other places, such as under the nails, in the eye, or in the intestines.
Treatment works best when melanoma is found early.
Melanoma begins in the cells (melanocytes) that make the pigment that colors your skin. It is a serious form of skin cancer that usually starts in unmarked, normal skin. But it can start in a mole or birthmark.
When melanocytes grow out of control, they can spread from the epidermis, which is the upper layer of skin, down into the dermis. Melanoma can spread rapidly to other parts of the body. Early diagnosis is important, since treatment works best when melanoma is found early.
You may not have any symptoms in the early stages of melanoma. Or a melanoma may be sore, or it may itch or bleed. Most melanomas start as a new skin growth. But any change in the shape, size, or color of a mole may be a sign of melanoma.
Treatment for melanoma is based on the stage of the cancer and other things, such as your overall health. The main treatment is surgery to remove the cancer. Other treatment options may include immunotherapy and targeted therapy.
If melanoma has spread beyond the skin (metastatic cancer), you may have surgery. You'll probably need other treatments too. These may include immunotherapy or targeted therapy. In some cases, radiation therapy or chemotherapy may be used.
Your doctor will talk with you about your options and then make a treatment plan.
The doctor removes the cancer and a border of normal skin (margin) around it. If you have early-stage cancer, the doctor may be able to remove all of it. You may not need more treatment.
If a large melanoma is removed, you may need a skin graft or other repair surgery.
In some cases, one or more lymph nodes may be removed.
After surgery, you may have only regular checkups. Or you may also have other treatments to help prevent a return (recurrence) of the cancer.
Medicines used to treat melanoma include:
Melanoma that has spread to other parts of the body (metastatic cancer) may cause tumors. These can sometimes be removed with surgery. But metastatic melanoma often needs other treatments too. Examples include immunotherapy, targeted therapy, and chemotherapy. These treatments and others may also be used for melanoma that has come back after treatment (recurrent cancer).
Radiation therapy may help relieve symptoms caused by melanoma that has spread to the bones or other organs. Radiation therapy uses high-dose X-rays to destroy cancer cells and shrink tumors.
Clinical trials are research studies that test new treatments to find out how well they work. Your medical team can tell you if there's a clinical trial that might be right for you.
The best way to lower your risk for melanoma is to protect your skin whenever you are out in the sun. For example, stay out of the sun during midday hours. Wear sun-protective clothes. Use sunscreen with an SPF of at least 30 every day. Avoid sunbathing and tanning salons.
Your doctor will check your skin for melanoma. If your doctor suspects melanoma, a sample of tissue (biopsy) will be removed and tested. If your biopsy shows melanoma, you may have more tests to find out if it has spread to your lymph nodes or other places.
What exactly causes melanoma isn't known. But some things, like too much UV radiation from sun exposure, can damage DNA. This can cause normal skin cells to become abnormal. These abnormal cells can quickly grow out of control.
Any of these things can put you at higher risk for this disease:
Melanoma is the most serious kind of skin cancer because it can quickly spread to other parts of the body. Most melanomas show up as a new spot or skin growth. But they can also form in an existing mole. Less often, melanoma begins in other places, such as the eye or the intestines.
