How Do Doctors Determine The Staging And Prognosis Of A Melanoma
The most useful criterion for determining prognosis is tumor thickness. Tumor thickness is measured in fractions of millimeters and is called the Breslow’s depth. The thinner the melanoma, the better the prognosis. Any spread to lymph nodes or other body locations dramatically worsens the prognosis. Thin melanomas, those measuring less than 0.75 millimeters when examined microscopically, have excellent cure rates, generally with local surgery alone. For thicker melanomas, the prognosis is guarded.
Melanoma is staged according to thickness, ulceration, lymph node involvement, and the presence of distant metastasis. The staging of a cancer refers to the extent to which it has spread at the time of diagnosis, and staging is used to determine the appropriate treatment. Stages 1 and 2 are confined to the skin only and are treated with surgical removal with the size of margins of normal skin to be removed determined by the thickness of the melanoma. Stage 3 refers to a melanoma that has spread locally or through the usual lymphatic drainage. Stage 4 refers to distant metastases to other organs, generally by spread through the bloodstream.
Articles On Skin Cancer
Skin cancer — abnormal cell changes in the outer layer of skin — is by far the most common cancer in the world. It can usually be cured, but the disease is a major health concern because it affects so many people. About half of fair-skinned people who live to age 65 will have at least one skin cancer. Most can be prevented by protecting your skin from the sun and ultraviolet rays.
Every malignant skin tumor will, over time, show up on the skin‘s surface. That makes this the only type of cancer that is almost always found in its early, curable stages.
Signs And Symptoms Of Melanoma
The most common sign of melanoma is the appearance of a new mole or a change in an existing mole.
This can happen anywhere on the body, but the most commonly affected areas are the back in men and the legs in women.
Melanomas are uncommon in areas that are protected from sun exposure, such as the buttocks and the scalp.
In most cases, melanomas have an irregular shape and are more than 1 colour.
The mole may also be larger than normal and can sometimes be itchy or bleed.
Look out for a mole that gradually changes shape, size or colour.
Superficial spreading melanoma are the most common type of melanoma in the UK.
They’re more common in people with pale skin and freckles, and much less common in people with darker skin.
They initially tend to grow outwards rather than downwards, so they do not pose a problem.
But if they grow downwards into the deeper layers of skin, they can spread to other parts of the body.
You should see a GP if you have a mole that’s getting bigger, particularly if it has an irregular edge.

Melanoma Most Lethal Of Skin Cancers
According to doctors regular skin examinations is of vital importance, because eventhis very dangerous cancer can be cured if it is discovered early.
People should get checked once a year “particularly if they havespent a lot of time in the sun,” advised Dr. Charles McDonald of Brown University, past president of the American Cancer Society.
Too often, melanoma is not caught early. Worse, it is very aggressive -tumours can double in size every month – and it can spread through the body quickly. Only 20-30 percent of people withadvanced melanoma live five years.
There are several types of skin cancer. Some, such as basal cell carcinoma, aren’t very aggressive and are usually curable.
Melanoma is the worst type. But catch it early, before the tumour grows too deep into the skin or spreads, and doctors can cut it out.
Indeed, surgery is melanoma’s main treatment, because unlike most other cancers, it doesn’t respond well to chemotherapy and radiation. “That’s what makes it so devastating,” McDonald said.
People who have survived one bout with melanoma are forever at high risk of getting it again. It can recur at the same spot – when that happens, the prognosis is very grim – or a totally new tumour can pop up somewhere else.
What causes melanoma?
The more sunburns, particularly early in life, the higher your risk. Fair-skinned people, consequently, are at highest risk.
Also at high risk are people with more than 20 moles scatteredaround their body, McDonald said.
A Dangerous Skin Cancer
Melanoma is a serious form of skin cancer that begins in cells known as melanocytes. While it is less common than basal cell carcinoma and squamous cell carcinoma , melanoma is more dangerous because of its ability to spread to other organs more rapidly if it is not treated at an early stage.
Only 20-30% of melanomas are found in existing moles.
While 70-80% arise on normal-looking skin.

What Is Most Dangerous Skin Cancer
1. Nodular melanoma
An most dangerous form of melanoma that looks various from common melanomas they are raised from the start and have an even coloring . This kind of melanoma grows really rapidly and needs to be dealt with as quickly as possible.
2. Basal cell carcinoma
This is the most typical but least dangerous kind of skin cancer. It grows slowly, generally on the head, neck and upper torso. It may look like a lump or dry, scaly area. It can be red, pale or pearly in color. As it grows, it may ulcerate or resemble a sore that does not recover correctly.
3. Squamous cell carcinoma
This type of skin cancer is not as dangerous as melanoma but may infect other parts of the body if not treated. It grows over some months and appears on skin most often exposed to the sun. It can be a thickened, red, flaky spot that may bleed quickly, crust or ulcerate.
Basal Cell And Squamous Cell Survival Rates
Because basal cell and squamous cell carcinomas are lower-risk skin cancers, theres little information on survival rates based on stage.
Both types of cancer have a very high cure rate. According to the Canadian Cancer Society, the five-year survival rate for basal cell carcinoma is 100 percent. The five-year survival rate for squamous cell carcinoma is 95 percent.

Major Types Of Treatments
Although surgical modalities remain the mainstay of treatment, new research and fresh innovation are still required to reduce morbidity and mortality . There has been innovation in skin cancer treatment in the last few years than in the previous 30 years . Here, we are not discussing treatment methodology in details but just an outline of currently applicable standard treatments for skin cancer is given .
Surgery: Most basal cell and squamous cell skin cancers can be successfully treated with surgery and early-stage melanomas are also cured. Thin layers are removed until no more cancer cells are seen.
Radiation Therapy: Radiation therapy uses high-energy rays or particles to kill cancer cells or prevent them from growing. It is used when cancer is widely spread, recurred and surgery is not possible.
Chemotherapy: Chemotherapeutic drugs are usually given as injection or taken by mouth as a pill. They travel through the bloodstream to all parts of the body and attack cancer cells and stop their growth by killing them or by stopping them from dividing.
Immunotherapy: Immunotherapy is the emerging new type of treatment that stimulates a persons own immune system to recognize and destroy cancer cells more effectively.
Targeted therapy: Targeted therapy is a type of treatment that uses drugs or other substances to attack cancer cells. Targeted therapies usually cause less harm to normal cells than chemotherapy or radiation therapy do.
What Causes Skin Cancer
Almost all skin cancers in Australia are caused by too much exposure to UV radiation. This is the part of sunlight that causes tanning, sunburn and skin damage over time. UV radiation also comes from non-natural sources such as sun beds .
While anyone can get skin cancer, it is more common if you are older. The risk is also higher if you have:
- previously had skin cancer or have family history of skin cancer
- fair or freckled skin, particularly if it burns easily or doesnt tan
- red or fair hair and light-coloured eyes
- a weakened immune system
- sunspots or irregular moles on your body
- worked, played sport or spent leisure time in the sun
- actively tan or use sun beds
If you have olive or dark skin, your skin produces more melanin, which protects against UV radiation. However, its still possible for you to develop skin cancer.

Diagnosis Of Skin Cancer
It is important to check your skin regularly and check with your doctor if you notice any changes.
In the majority of cases, your GP will examine you, paying attention to any spots that may look suspicious. Your GP may perform a biopsy . In some cases your GP may refer you to a specialist, such as a dermatologist, if necessary.
Stop Tumors In Their Tracks
Every melanoma has the potential to become deadly, but the difference between an in situ melanoma and one that has begun to metastasize cannot be overstated. There is a drastic change in the survival rate for the various stages of tumors, highlighting the importance of detecting and treating melanomas before they have a chance to progress. Its impossible to predict exactly how fast a melanoma will move from stage to stage, so you should be taking action as soon as possible.
To be sure youre spotting any potential skin cancers early, The Skin Cancer Foundation recommends monthly skin checks, and scheduling an annual total-body skin-exam with a dermatologist. These skin exams can help you take note of any new or changing lesions that have the potential to be cancerous, and have them biopsied and taken care of before they can escalate.
Trust your instincts and dont take no for an answer, Leland says. Insist that a doctor biopsy anything you believe is suspicious.

Who Gets Skin Cancer
Skin cancer tends to affect people of light skin color because they’re born with the least amount of protective melanin in their skin. The odds are highest if you’re:
- A blue-eyed blonde
- Someone with a pigment disorder, such as albinism
People with many freckles or moles, particularly odd-looking ones, may be vulnerable to melanoma. It’s possible for dark-skinned people to get skin cancer, but it’s rare and usually on lighter areas of their body, such as the soles of the feet or under fingernails or toenails.
Where you live also plays a role. Places with intense sunshine, such as Arizona and Hawaii, have a larger share of people with skin cancer. It’s more common in places where fair-skinned people moved from less sunny areas, like Australia, which was settled largely by fair-skinned people of Irish and English descent.
About 3 times more men than women get skin cancer. It’s more likely when you’re older. Most people diagnosed are between ages 45 and 54, although more younger people are now being affected. If you or any close relatives have had skin cancer, your chances go up.
Red Flag #: Swollen Lymph Nodes
If melanoma spreads, it often goes to the lymph nodes first, says Melinda L. Yushak, M.D., assistant professor of hematology and medical oncology at Emory University School of Medicine in Atlanta. The cancer cells will first travel to the nodes closest to the original tumor, she says. Lymph nodes are located throughout your entire body, but large clusters are found in the neck, underarms, chest, abdomen, and groin. If the cancer has made its way to the lymph nodes, it usually wont be painful, but theyll feel swollen or even hard to the touch, Dr. Zaba says.
