What You Can Do
Check yourself: No matter your risk, examine your skin;head-to-toe once a month to identify potential skin cancers early. Take note of existing moles or lesions that grow or change. Learn how to check your skin here.
When in doubt, check it out. Because melanoma can be so dangerous once it advances, follow your instincts and visit your doctor if you see a spot that just doesnt seem right.
Keep in mind that while important, monthly self-exams are not enough. See your dermatologist at least once a year;for a professional skin exam.
If youve had a melanoma, follow up regularly with your doctor once treatment is complete. Stick to the schedule your doctor recommends so that you will find any recurrence as early as possible.
How Is Skin Cancer Diagnosed
Your doctor or dermatologist will first conduct a physical examination by looking at your skin to identify any suspicious spots using a dermatoscope .
Its not always possible to tell from looking at it whether a spot or lump is cancerous or not. So your doctor or dermatologist may take a skin biopsy. This is where part of, or all of, your spot is removed and sent for further study under a microscope.
Some smartphone apps allow you to photograph your skin and compare photos over time. While they can be a good reminder to check your skin and record details, they shouldnt replace a visit to the doctor. See a doctor if youre concerned about any spots or moles on your skin.

Does Your Risk Of Melanoma Increase If You Have Been Diagnosed With It In The Past
If you’ve had one type of skin cancer or melanoma, you are much more likely to develop it again in your lifetime. Dr. Whitman said your chances depend on your initial diagnosis, your age and your family health history. In fact, if you have a parent or sibling who developed melanoma, it doubles your risk of developing the condition.
Skin Cancer Of The Head And Neck Treatment
Many early-stage small basal cell cancers or squamous cell cancers can be removed by Mohs surgery, a technique that spares normal tissue through repeated intraoperative margin testing, removing only the cancer and leaving adjacent normal tissue. Tumors with nerve involvement, lymph node involvement or of a large size are not suitable for Mohs surgery. They require a multimodality approach to treatment, with formal surgical resection and adjuvant radiation or chemotherapy.
Melanoma is more likely to spread, and aggressive surgical resection with wide margins is required, in addition to radiation and/or chemotherapy.

When To Contact A Doctor
Early detection of melanoma increases the number of treatment options available and the likelihood of recovery. If a person notices any new or unusual marks on their skin, it is important for them to contact a doctor.
Performing regular self-checks and knowing which symptoms to look out for can help them detect skin cancer early.
Use the ABCDE rules as a guide, but remember that some marks may not match these descriptions.
Treatment Options For Metastatic Melanoma
Surgery is generally not effective in curing melanoma that is known to have spread to other parts of the body such as the lungs or the brain . However, surgery may still be done to help control the spread of the cancer, lessen symptoms, and improve survival. In such cases, doctors may use other methods of treatment, such as:
- Immunotherapy: Drugs that stimulate the immune system to fight the cancer.
- Targeted drug treatment: Drugs that act on specific molecules that are needed by the cancer cells.
- Chemotherapy: Drugs that interfere with cancer cell growth or reproduction.
- Radiation therapy: Using external radiation to kill cancer cells.
- A combination of any of these methods
When therapy is given after surgery to remove all cancerous tissue, the treatment is called adjuvant therapy. The goal of adjuvant therapy is to kill any undetected cancer cells that may remain in the body.
Immunotherapy is a newer form of treatment that uses the body’s immune system to fight the melanoma. The immune checkpoint inhibitors are used in melanoma; sometimes they are used in combination. Immune checkpoint inhibitors include:
Keytruda and Opdivo are PD-1 inhibitors and Yervoy is known as a CTLA-4 inhibitor, and they help to strengthen the immune response to cancer.
More recent approvals include:

Can Changing My Diet Help Prevent Melanoma
The American Cancer Society advocates eating a plant-based diet over an animal-based diet as part of a healthy plan to avoid all cancers. Growing evidence suggests that plants pack a powerful punch in any fight against cancer because they’re nutritious, cholesterol-free and fiber-rich.
Theres no doubt that a healthy diet can protect your immune system. Having a strong immune system is important to help your body fight disease. Some research has shown that a Mediterranean diet is a healthy choice that may help prevent the development of cancer. Talk to your healthcare provider about the role food plays in lowering your cancer risks.
Some skin and immune-system healthy foods to consider include:
- Daily tea drinking: The polyphenols in tea help strengthen your immune system. Green tea contains more polyphenols than black tea.
- High vegetable consumption: Eating carrots, cruciferous and leafy vegetables is linked to the prevention of cutaneous melanoma.
- Weekly fish intake: Study participants who ate fish weekly seemed to avoid developing the disease when compared to those who did not eat fish weekly.
What Are The Symptoms Of Melanoma That Has Spread
Melanoma that has spread from the skin to other areas of the body is known as metastatic melanoma. However, since melanoma often first presents itself as an abnormal mole, many people with this malignancy can receive a diagnosis before the cancer has spread. This mole may be asymmetrical, have an uneven border, have an inconsistent color, be large or change over time. A melanoma may also appear as a sore or itchy bump, a tender nodule or a patch of skin that is scaly or bleeding. In some cases, early signs of melanoma are not present. For example, if the cancer starts in a mucous membrane rather than on the skin, a mole may not be present.

Squamous Cell Carcinoma Signs And Symptoms
Like basal cell carcinoma, squamous cell carcinoma usually occurs because of repeated sun exposure over time. This skin cancer is a slow-developing skin cancer that can spread to other areas of the skin, although it is still considered uncommon to spread widely.
Squamous cell carcinoma normally takes the form of:
- wart-like bumps that often have crusted surfaces
- rough, scaly patches that may bleed
- an open sore that bleeds or develops a crust
- red, dome-like nodules
Bowens disease, also known as squamous cell carcinoma in situ, is an early form of squamous cell carcinoma. It usually appears as a red, itchy scaly patch that can often be confused for psoriasis or eczema. It is easily treated, but if left undiagnosed, it can pose a risk.
What Are The Survival Rates For Metastatic Melanoma
Survival rates for melanoma, especially for metastatic melanoma, vary widely according to many factors, including the patient’s age, overall health, location of the tumor, particular findings on the examination of the biopsy, and of course the depth and stage of the tumor. Survival statistics are generally based on 5-year survival rates rather than raw cure rates. Much of the success reported for the targeted therapies focuses on disease-free time because in many cases the actual 5-year survival is not affected. It is hoped that combination therapy discussed above will change that.
- For stage 1 , 5-year survival is â¥ 90%.
- For stage 2 , 5-year survival is 80%-90%.
- For stage 3 , 5-year survival is around 50%.
- For stage 4 , 5-year survival is 10%-25% depending upon sex and other demographic factors.

When To See A Healthcare Provider
If you notice any of the signs or symptoms of skin cancer mentioned above, make an appointment to see your healthcare provider. A dermatologist can examine your skin;and determine if a biopsy is needed. This is true no matter your skin color.
Skin cancer can more difficult to see;or may look different on darker skin, and even healthcare providers can overlook melanomas in people of color. If you are concerned, but do not feel that your concern is being addressed, be your own advocate and continue to ask questions or get a second opinion.

Melanoma Signs And Symptoms
Melanoma is often considered to be the most dangerous type of skin cancer. It can develop on any part of the body but is more prevalent on exposed parts like the arms and face. There are some signs that are more obvious than others, and checking for these;signs first is advised.
These symptoms can be detected using the ABCDEs of Melanoma:
- Asymmetrical spots
- Diameter increases
- Evolving in size, shape, or color
Its important to note that sometimes, a mole is just a mole. But if a mole that was the size of a pinhead has suddenly doubled and become bumpy, this is a strong indicator of melanoma

What Is Melanoma Cancer
Melanoma is a serious type of skin cancer. Most melanoma is treated surgically, and in many cases this surgery is curative. Through numerous clinical trials, the surgery that is required to treat melanoma has become less invasive. A number of these less radical procedures were pioneered at the Saint Johns Cancer Institute Melanoma Program.
100,350people in the U.S. will be diagnosed with melanoma in 2020 and the American Cancer Society estimates that number will continue to increase year after year.

Merkel cell carcinoma is a rare type of skin cancer that usually appears as a flesh-colored or bluish-red nodule, often on your face, head or neck. It is an aggressive, fast-growing type of skin cancer. Merkel cell carcinoma most frequently develops in older people. Long-term sun exposure or a weak immune system may increase your risk of developing Merkel cell carcinoma.
Treatment options for Merkel cell carcinoma often depend on whether the cancer has spread beyond the skin. Bavencio , a PD-L1 blocking antibody, and pembrolizumab , a PD-1 inhibitor, are recently approved immunotherapies for treatment of Merkel cell carcinoma.

The Abcde’s Of Melanoma: Signs To Look For
Melanoma has an easy-to-remember list of signs: the ABCDE’s. These letters identify the characteristics of moles that are most likely to form melanoma.
You and your doctor can look at your moles, taking note of the following:
- A = Asymmetry sides of the mole or lesion do not match.
- B = Border melanomas tend to have uneven borders.
- C = Color melanomas tend to have a variety of colors in a single lesion.
- D = Diameter melanomas tend to be larger than benign moles.
- E = Evolution melanomas evolve or change over time.
Melanomas That Could Be Mistaken For A Common Skin Problem
Melanoma that looks like a bruise
Melanoma can develop anywhere on the skin, including the bottom of the foot, where it can look like a bruise as shown here.
Melanoma that looks like a cyst
This reddish nodule looks a lot like a cyst, but testing proved that it was a melanoma.
In people of African descent, melanoma tends to develop on the palm, bottom of the foot, or under or around a nail.
Did you spot the asymmetry, uneven border, varied color, and diameter larger than that of a pencil eraser?
Dark line beneath a nail
Melanoma can develop under a fingernail or toenail, looking like a brown line as shown here.
While this line is thin, some are much thicker. The lines can also be much darker.

A Sore That Doesn’t Heal
Many skin cancers are first dismissed as being due to a bug bite, minor injury, or irritation, but become more obvious when they don’t go away over time. If you notice a sore on your skin that refuses to heal, even if it seems to be healing but then reappears, talk to your healthcare provider. In general, any skin change that hasn’t resolved on its own over a period of two weeks should be evaluated.;
What Treatments Are Used For Actinic Keratosis
Actinic keratoses have a variety of treatment options based upon the extent of lesions:
- Freezing with liquid nitrogen is most commonly used to treat actinic keratoses. This takes only a few minutes. The area sloughs off, allowing new skin growth. Side effects may include blisters, skin redness, and changes in skin texture or color at the site of treatment. These spots usually clear up in a week or two.
- Electrodesiccation and curettage : after numbing, the precancerous area is surgically scraped with a spoon-shaped tool and then treated with an electric current to control bleeding. A white scar may occur.
- Topical creams may also be used, especially if there are several areas to treat. Redness, peeling or a slight burning sensation may occur for a few weeks. Scarring is uncommon.
- involves the application of a chemical solution and exposure of the area to artificial light to destroy the damaged skin cells. Side effects may include redness, peeling, swelling, scarring or a burning sensation during therapy.

Melanoma And Skin Cancer Risk Factors
Risk factors increase the chance a person might get skin cancer. In some cases, people can change their habits or job to reduce or eliminate skin cancer risk factors.
The main risk factor for melanoma and other skin cancers is unprotected exposure to ultraviolet radiation. This can be in the form of either sunlight or tanning bed beams.
Other factors that can increase your risk for skin cancer are:
- A large number of moles or atypical moles.
- Fair skin, eyes, or hair.
- Prior skin cancer diagnosis.
- Weakened immune system from chemotherapy, HIV/AIDS, or anti-rejection drugs after an organ transplant.
What Are The Treatments For Metastatic Melanoma
Historically, metastatic and recurrent melanoma have been poorly responsive to chemotherapy. Immunotherapy, in which the body’s own immune system is energized to fight the tumor, has been a focus of research for decades. A variety of newer medications target different points in the pathways of melanoma cell growth and spread. While the most appropriate use of these medications is still being defined, the best treatment for melanoma remains complete surgical excision while it is still small, thin, and has not yet had a chance to spread.

What Are The Signs And Symptoms Of Melanoma
Melanoma is a skin cancer that can show up on the skin in many ways. It can look like a:
Spot that looks like a new mole, freckle, or age spot, but it looks different from the others on your skin
Spot that has a jagged border, more than one color, and is growing
Dome-shaped growth that feels firm and may look like a sore, which may bleed
Dark-brown or black vertical line beneath a fingernail or toenail
Band of darker skin around a fingernail or toenail
Slowly growing patch of thick skin that looks like a scar
This early melanoma could be mistaken for a mole, so its important to look carefully at the spots on your skin.
Look Out For An Ugly Duckling
The Ugly Duckling is another warning sign of melanoma. This recognition strategy is based on the concept that most normal moles on your body resemble one another, while melanomas stand out like ugly ducklings in comparison. This highlights the importance of not just checking for irregularities, but also comparing any suspicious spot to surrounding moles to determine whether it looks different from its neighbors. These ugly duckling lesions or outlier lesions can be larger, smaller, lighter or darker, compared to surrounding moles. Also, isolated lesions without any surrounding moles for comparison are considered ugly ducklings.

Diagnosis Of Skin Cancer
Doctors should check the skin during a routine physical exam, and dermatologists are specially trained to do this check. People who have already had skin cancer, or are at high risk, should be sure to have regular exams. When an area of skin does not look normal, the doctor may remove all or part of the growth using a local anesthetic so it is not painful. This is procedure is called a biopsy. The tissue is examined to check for cancer cells.
- Nonmelanoma skin cancer: Because basal cell carcinomas and squamous cell carcinomas rarely spread beyond the skin, a biopsy and microscopic examination often is the only test needed.
- Melanoma: If your doctor suspects you have melanoma, you may have additional biopsies or imaging tests. The entire area will be removed if possible. The doctors may categorize the cancer using Stages I to IV based upon whether the cancer has spread to other parts of the body. Knowing the stage of a skin cancer helps to determine the best treatment plan. The nearby lymph nodes in the area may be checked, and may need to be removed.
The cure rate for skin cancer is very high if detected early. It is important to examine the skin regularly to check for new growths or other changes in the skin. Any new, colored growths or any changes in growths that are already present should be reported to a doctor without delay.
