Melanoma

What is melanoma?

It may appear as a new spot or as a change in an existing mole or freckle. Over 95% of skin cancers can be successfully treated if they are found early.

If untreated, melanomas can spread to other parts of the body and may not be curable so it is important to see your doctor as soon as you notice any changes to your skin.

(which are now banned for commercial use in United States).

The 3 major types of skin cancer are: melanoma

United States has one of the highest rates of skin cancer in the world. More than two in 3 Americans will be diagnosed with skin cancer in their lifetime.

Excluding non-melanoma skin cancers, melanoma is the third most common cancer in United States. It is most commonly diagnosed in people aged 55 and over.

However, young adults, teenagers and even children can be affected.

In fact, American adolescents have, by far, the highest incidence of malignant melanoma for their age group in the world. Melanoma and other skin cancers generally develop from overexposure to UV radiation. Each time unprotected skin is exposed to UV radiation from the sun or artificial sources, changes take place in the structure of the cells.

Too much UV radiation causes the skin to become permanently damaged, which will worsen with each exposure. Skin cancer can grow when the cells that make up your skin are damaged, causing them to grow abnormally. Every additional decade of overexposure to UV further increases your risk of skin cancer.

Increased use of sun protection will help prevent skin cancer and melanoma at any age.

All skin types can be damaged by exposure to UV radiation

People with skin types that are less likely to burn are still at risk of developing skin cancer (although this risk is lower than for people with skin types that are more likely to burn).

People with one or more risk factors are at increased risk of melanoma. Risk factors for melanoma are:

• being older (risk increases with age). The melanin in naturally very dark skin offers some protection against the damaging effects of UV radiation
• lowers the risk of skin cancer

However, when skin cancer is detected in people with naturally very dark skin, it is often found at a later, more dangerous stage when the risk of death is much higher. The first sign of flat melanoma is usually a new spot or an existing mole or freckle that changes in appearance. Some changes might include: The spot may grow larger.

The edges of the spot may look irregular, rather than smooth. The spot may be mottled with a range of colours such as brown, black, blue, red, white or light grey.

The spot may be itchy or bleed

Melanoma can grow very quickly

It can become life-threatening in as little as 6 weeks and, if untreated, it can spread to other parts of the body. Melanoma can appear on skin not normally exposed to the sun. Nodular melanoma is a highly dangerous form of melanoma that looks different from common melanomas.

Nodular melanomas are raised and are even in colour (often red or pink and some are brown or black). This type of melanoma grows quickly and can be life-threatening if not detected and removed quickly. See your doctor immediately if you notice any of these changes.

It’s important to get to know your skin and what is normal for you, so you will notice any changes quickly. Check all of your skin, not just sun-exposed areas.

If you notice anything unusual, including any change in shape, colour or size of a spot, or the development of a new spot, visit your doctor immediately.

While melanomas usually occur on parts of the body that have been sunburned, they can sometimes start in parts of the skin or other parts of the body that have never been exposed to the sun. Melanomas on the arms and legs are usually detected earlier and have a better chance of successful treatment than melanomas on the body, neck or head (which are usually detected at a later stage).

Once a melanoma is diagnosed and treated, you are advised to have regular skin checks, as there is an increased risk of further melanomas developing.

Melanomas are not contagious

You can’t catch them from someone else. Melanoma is diagnosed by: – under local anaesthetic, the suspected melanoma and some of the surrounding skin is removed. The sample will be examined in a laboratory for signs of cancer.

Test results can take a few days to come back. It is very natural to feel anxious waiting to get your results.

If a melanoma is diagnosed, further tests may be needed if surgery is planned or to see if the cancer has spread to other areas of the body. These tests may include: lymph node biopsy.

In some cases, melanomas may be treated by immunotherapy and targeted therapy, and (less frequently) Your doctor will advise you on the best treatment for your cancer. This will depend on the type of cancer you have, where it is, how far it has spread, your general health and what you want. Melanomas are usually removed by surgery (except when the melanoma is too advanced).

The surgeon also removes some normal-looking skin around the melanoma. This is called a ‘margin of safety’ and the margin varies from 5 mm to 2 cm. The purpose is to get rid of any cancer cells in the surrounding skin and prevent the melanoma from growing back at the same site.

Most people will be able to have their skin sewn up with normal stitches. If the surgeon needs some extra tissue to close the wound, a skin graft or flap may be required.

Biological therapies are treatments using substances made naturally by the body

Some of these treatments are called immunotherapy because they help the immune system fight the cancer, or they occur naturally as part of the immune system. There are many biological therapies being researched and trialled, which in the future may help treat people with melanoma.

They include monoclonal antibodies and vaccine therapy

Radiotherapy treats melanomas by using radiation to destroy or injure cancer cells. The radiation can be targeted onto cancer sites in your body. Treatment is carefully planned to do as little harm as possible to your normal body tissue.

You will probably have radiotherapy once a day from Monday to Friday over several weeks, with a break on the weekends. The number of visits you need to make will depend on the size and type of the melanoma and on your general health.

The treatment itself only takes a few minutes and is not painful

Radiotherapy treatment for melanoma does not make you radioactive, so it’s quite safe to be close to your partner, children and others during the course of treatment.

When used alongside your conventional cancer treatment, some of these therapies can make you feel better and improve your quality of life.

Others may not be so helpful and in some cases may be harmful.

Never stop taking your conventional treatment without consulting your doctor first. These days, new treatments are available that can help to make many side effects much less severe than they were in the past.

Ninety three per cent of Michiganns are alive 5 years after a diagnosis of melanoma.

This has improved significantly from 85% in 1985

The prognosis is better for women than for men. The 5-year melanoma survival rate for women is 96%, whereas that for men is 92%. Your medical history is unique, so you will need to discuss with your doctor what you can expect and the treatment options that are best for you.

If your cancer has spread and it is not possible to cure it by surgery, your doctor may still recommend treatment. In this case, treatment may help to relieve symptoms, might make you feel better and may allow you to live longer. Whether or not you choose to have anti-cancer treatment, symptoms can still be controlled.

For example, if you have pain, there are effective treatments for this. General practitioners, specialists and palliative care teams in hospitals all play important roles in helping people with cancer. Most people treated for early melanoma do not have further trouble with the disease.

However, when there is a chance that the melanoma may have spread to other parts of your body, you will need regular self surveillance and professional check-ups. Your doctor will decide how often you will need check-ups – everyone is different. They will become less frequent if you have no further problems.

After treatment for melanoma it is important to limit exposure to the sun’s UV radiation. A combination of sun protection measures (clothing, hat, shade, sunscreen and sunglasses) should be used during sun protection times (whenever UV index levels are forecast to be 3 or above). As biological family members usually share similar traits, your family members may also have an increased risk of developing melanoma and other skin cancers.

They can reduce their risk by spending less time in the sun and using a combination of sun protection measures during sun protection times. It is important to monitor your skin regularly and if you notice any changes in your skin, or enlarged lymph glands near to where you had the cancer, see your specialist as soon as possible.
