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.
Difference Between Carcinoma And Adenocarcinoma

Carcinoma vs Adenocarcinoma
The word cancer is one thing that most patients are afraid to hear from their doctors. I am not talking about a constellation here, but rather, a disease condition. It is a word that could strike fear to the hearts of those who hear it or something to that effect. True enough, most individuals who have been diagnosed with cancer are faced with a humongous task of fighting that disease, a seemingly insurmountable mountain to climb. This is because there has never been a discovered cure for cancer, and the most that physicians can do is to use a combination of therapies to kill the cancer cells before they has a time to spread elsewhere in the body.
Actually, what then is cancer? The simplest explanation would be this. It is a common word used to denote an irreversible mutation of normal cells in some parts of our body. This indicates that a seemingly normal and healthy cell can just turn into a mutated and dangerous form due to a number of causes. What makes it dangerous is that rather than die out when it has served its purpose, the cell becomes aggressive and lives on. It can affect the other cells, cause damage to the surrounding areas, and can even penetrate tissues around it. This is the nature of a cancer cell.
That is the difference between the two terms. You can read further into this topic since basic details are only provided here.

What Is A Skin Doctor
A skin doctor is a qualified and experienced doctor, who has specific expertise in treating skin.
In addition to their medical degrees, they have particular specialist qualifications in the diagnosis and treatment of skin conditions. The clinical conditions a skin doctor can treat range from skin cancer checks to acne, dermatitis , hyperhidrosis , hyperpigmentation and rosacea.
In some cases, prescriptions are needed for patients to access stronger medicines and medical-grade skin treatments. A skin doctor has the capacity to prescribe stronger and more effective treatments when needed.
Skin doctors are also members of medical organisations, are bound by strict rules of practice, and are often involved in the latest research.

What Is Skin Cancer
Basal cell carcinoma begins in the basal cell layer of the skin. Squamous cell carcinoma begins in the squamous layer of the skin. Melanoma begins in the melanocytes, which are the cells that make melanin, the pigment that gives skin its color.
Basal cell carcinoma begins in the basal cell layer of the skin. Squamous cell carcinoma begins in the squamous layer of the skin. Melanoma begins in the melanocytes, which are the cells that make melanin, the pigment that gives skin its color.
The skin is the bodys largest organ. Skin has several layers, but the two main layers are the epidermis and the dermis . Skin cancer begins in the epidermis, which is made up of three kinds of cells
- Squamous cells: Thin, flat cells that form the top layer of the epidermis.
- Basal cells: Round cells under the squamous cells.
- Melanocytes: Cells that make melanin and are found in the lower part of the epidermis. Melanin is the pigment that gives skin its color. When skin is exposed to the sun, melanocytes make more pigment and cause the skin to darken.
Basal and squamous cell carcinomas are the two most common types of skin cancer. They begin in the basal and squamous layers of the skin, respectively. Both can usually be cured, but they can be disfiguring and expensive to treat.
Recurrent Basal Cell Carcinoma
Basal cell carcinomas are the most common type of skin cancer, according to the American Cancer Society. These cancers develop within the basal cell layer of the skin, in the lowest part of the epidermis.
Patients who have had basal cell carcinoma once have an increased risk of developing a recurrent basal cell cancer. Basal cell cancers may recur in the same location that the original cancer was found or elsewhere in the body. As many as 50 percent of cancer patients are estimated to experience basal cell carcinoma recurrence within five years of the first diagnosis.
Basal cell carcinomas typically grow slowly, and it is rare for them to metastasize or spread to nearby lymph nodes or other parts of the body. But early detection and treatment are important.
After completing treatment for basal cell carcinoma, it is important to perform regular self-examinations of the skin to look for new symptoms, such as unusual growths or changes in the size, shape or color of an existing spot. Skin cancers typically develop in areas of the body that are exposed to the sun, but they may also develop in areas with no sun exposure. Tell your oncologist or dermatologist about any new symptoms or suspicious changes you may have noticed.
- Have a history of eczema or dry skin
- Have been exposed to high doses of UV light
- Had original carcinomas several layers deep in the skin
- Had original carcinomas larger than 2 centimeters

Melanoma Vs Sarcoma: Identifying The Difference
Finding a lump or a new spot on your skin can be scary. Youre not sure what exactly it means or if its dangerous. The best thing you can do if you notice a lump or changing spot is to see a dermatologist as soon as possible. While youre waiting to see your doctor, its good to do some research on your own so that you have a better understanding about what you are experiencing.
If youre worried about melanoma or sarcoma, were going to help you discover the differences between the two by describing what each looks like and some common symptoms.
What Are The Symptoms Of Skin Cancer
Skin cancers first appear as a spot, lump or scaly area on the skin, or a mole that changes colour, size or shape over several weeks or months. These changes can appear anywhere on the body, particularly areas frequently exposed to the sun. Skin cancers may bleed and become inflamed, and can be tender to the touch.
There are certain characteristics to look for in spots and moles. Remember the ‘ABCDE’ of skin cancer when checking your skin:
- Asymmetry does each side of the spot or mole look different to the other?
- Border is it irregular, jagged or spreading?
- Colours are there several, or is the colour uneven or blotchy?
- Diameter look for spots that are getting bigger
- Evolution is the spot or mole changing or growing over time?
Changes may include an area that is scaly, shiny, pale or bright pink in colour, or a spot or lump that grows quickly and is thick, red, scaly or crusted.
See your doctor if you notice any new spots or an existing spot that changes size, shape or colour over several weeks or months. Your doctor can help you distinguish between a harmless spot such as a mole, and a sunspot or irregular mole that could develop later into skin cancer.

Squamous Cell Carcinoma: Common In Sun
Squamous cell carcinoma, also called squamous cell cancer, is the second most common type of skin cancer. It accounts for about 20 percent of cases.
This type of cancer starts in flat cells in the outer part of the epidermis. It commonly crops up on sun-exposed areas, such as the face, ears, neck, lips, and hands. It can also develop on scars or chronic sores.
Squamous cell carcinomas may develop from precancerous skin spots, known as actinic keratosis .
These cancers might look like:
- A firm, red bump
- A flat lesion with a scaly, crusted surface
- A sore that heals and then reopens
People with lighter skin are more at risk for developing squamous cell carcinoma, but the skin cancer can also affect those with darker skin.
Other risk factors include:
- Having light eyes, blond or red hair, or freckles
- Being exposed to the sun or tanning beds
- Having a history of skin cancer
- Having a history of sunburns
- Having a weakened immune system
- Having the genetic disorder xeroderma pigmentosum

From The Harvard Health Letter May 2006
Summers the season for fun in the sunbut also for skin cancer. Of the three main types of skin cancer, melanoma is most deadly, and basal cell, most common. Squamous cell cancer falls in between. Its three times as common as melanoma . Though not as common as basal cell , squamous cell is more serious because it is likely to spread . Treated early, the cure rate is over 90%, but metastases occur in 1%5% of cases. After it has metastasized, its very difficult to treat.

What Is A Melanocyte
Melanocytes are skin cells found in the upper layer of skin. They produce a pigment known as melanin, which gives skin its color. There are two types of melanin: eumelanin and pheomelanin. When skin is exposed to ultraviolet radiation from the sun or tanning beds, it causes skin damage that triggers the melanocytes to produce more melanin, but only the eumelanin pigment attempts to protect the skin by causing the skin to darken or tan. Melanoma occurs when DNA damage from burning or tanning due to UV radiation triggers changes in the melanocytes, resulting in uncontrolled cellular growth.
About Melanin
Naturally darker-skinned people have more eumelanin and naturally fair-skinned people have more pheomelanin. While eumelanin has the ability to protect the skin from sun damage, pheomelanin does not. Thats why people with darker skin are at lower risk for developing melanoma than fair-skinned people who, due to lack of eumelanin, are more susceptible to sun damage, burning and skin cancer.
Surgery For Skin Cancer
Small skin cancer lesions may be removed through a variety of techniques, including simple excision , electrodesiccation and curettage , and cryosurgery .
Larger tumors, lesions in high-risk locations, recurrent tumors, and lesions in cosmetically sensitive areas are removed by a technique called Mohs micrographic surgery. For this technique, the surgeon carefully removes tissue, layer by layer, until cancer-free tissue is reached.
Malignant melanoma is treated more aggressively than just surgical removal. To ensure the complete removal of this dangerous malignancy, 1-2 cm of normal-appearing skin surrounding the tumor is also removed. Depending on the thickness of the melanoma, neighboring lymph nodes may also be removed and tested for cancer. The sentinel lymph node biopsy method uses a mildly radioactive substance to identify which lymph nodes are most likely to be affected.

Whats The Difference Between Melanoma And Non

With the skin as the largest organ of the body, it is understandable skin cancer is the most common type of human cancer. The American Cancer Society estimates there will be approximately 73,000 new cases of melanoma diagnosed in 2015 and 3.5 million cases of basal and squamous cell skin cancer. In its basic form, cancer occurs when a previously normal cell undergoes a transformation and begins to grow abnormally and multiply. As the abnormal cells multiply they form a mass or tumor. If the tumor is malignant it will begin to invade neighboring tissues, restricting oxygen and vital nutrients needed for the surrounding tissues to survive. Malignant tumors may also metastasize or travel via the blood stream to other organs.
Many people consider skin cancer and melanoma to be synonymous when in fact melanoma is only one form of skin cancer. Melanoma is by far the most aggressive and deadly, and perhaps the most universally known. Melanoma begins in the cells found in the lowest layer of the epidermis referred to as the melanocytes. These cells are responsible for pigment within the skin giving it a brown color. Melanoma most often is found on the skin, even on areas normally not exposed to the sun, and can also start in other parts of the body such as the eyes or mouth. The risk of melanoma increases as people age.

What Are The Treatment Options For Melanoma
Surgery performed to remove the melanoma while leaving as much nearby skin intact as possible. The surgeon may also remove one or more nearby lymph nodes to look for signs that the cancer has spread.
Targeted therapy uses drugs directed at specific abnormal proteins in cancer cells. Patients whose melanoma carries a mutation in the BRAF gene may be treated with drugs that target the altered BRAF protein or the associated MEK proteins. Three drug combinations have been FDA-approved for metastatic and high-risk melanoma with a BRAF mutation: dabrafenib and trametinib encorafenib and binimetinib and vemurafenib and cobimetinib
Immunotherapy uses the bodys immune system to fight cancer cells. Dana-Farber scientists have led clinical trials of the drug ipilimumab, one of a class of immunotherapy drugs that are helping some patients with advanced melanoma survive 10 years or longer. In other Dana-Farber-led trials, the immunotherapy agent nivolumab achieved three-year survival rates of more than 40% in patients with metastatic melanoma. Dana-Farber investigators have also found that initially treating advanced melanoma patients a combination of nivolumab and ipilimumab results in a much higher response rate than treatment with ipilimumab alone. A range of other clinical trials testing various immunotherapies is also under way for patients with advanced melanoma.

Difference Between Skin Cancer And Melanoma
Skin Cancer vs Melanoma
Melanoma is a type of highly invasive skin cancer. It is the most dangerous and most frequently heard of cancer of the skin. However, there are many other types of skin cancers, as well. This article will outline the causes, clinical features, symptoms, investigation and diagnosis, prognosis, and treatment of skin cancers, especially of melanoma.
Melanoma
Melanoma is a highly invasive carcinoma. It is an uncontrollable overgrowth of melanocytes. Melanocytes are responsible for producing skin pigments. Therefore, melanoma can arise from any part of the body where there are melanocytes. In the UK, 3500 new cases are identified per year. 800 people have died only during the last 20 years. Melanoma is commoner among Caucasians. It is commoner in females.
Prevention of exposure to UV light is thought to be preventive of melanoma. As a rule of thumb, avoiding sun exposure between 9 am and 3 pm is a good method. Sun creams and other preparations may help, but there is a risk of allergies and other skin changes with the use of these applications. Less invasive melanomas with lymph node spread have a better prognosis than deep melanomas without lymph node spread. When melanoma is spread to lymph node, the number of involved nodes is related to prognosis. Widely metastatic melanoma is said to be incurable. Patients tend to survive 6 to 12 months after diagnosis.
