Determining If The Cancer Has Spread
As part of your diagnosis, your doctor will also determine what stage the cancer is in. The different stages refer to whether and how far the cancer has spread in your body, on a Roman numeral scale of I to IV. A stage I cancer is small and contained to the body part where it originated, whereas a stage IV cancer has spread aggressively to other parts of the body.
Depending on the type of skin cancer that a person has, it may be more or less likely that it has spread through the body. For instance, basal cell skin cancer rarely spreads beyond the skin where it starts. However, melanomas and large squamous cell carcinomas are more likely to spread into other regions of the body. Cases of melanoma, in particular, may call for further tests to determine the specific stage theyre in.
Your doctor may evaluate multiple factors in order to stage the cancer. Using biopsies and imaging tests, your doctor may take a look at:
The size and thickness of the tumor, and whether it has grown into surrounding tissues
Nearby lymph nodes, to check for signs of cancer spread
Squamous Cell Carcinoma In Situ
This photo contains content that some people may find graphic or disturbing.
Squamous cell carcinoma in situ, also known as Bowens disease, is a precancerous condition that appears as a red or brownish patch or plaque on the skin that grows slowly over time. The patches are often found on the legs and lower parts of the body, as well as the head and neck. In rare cases, it has been found on the hands and feet, in the genital area, and in the area around the anus.
Bowens disease is uncommon: only 15 out of every 100,000 people will develop this condition every year. The condition typically affects the Caucasian population, but women are more likely to develop Bowens disease than men. The majority of cases are in adults over 60. As with other skin cancers, Bowens disease can develop after long-term exposure to the sun. It can also develop following radiotherapy treatment. Other causes include immune suppression, skin injury, inflammatory skin conditions, and a human papillomavirus infection.
Bowens disease is generally treatable and doesnt develop into squamous cell carcinoma. Up to 16% of cases develop into cancer.

Spots that are changing and growing.
These are some changes to look out for when checking your skin for signs of any cancer:
- New moles.
- Moles that increases in size.
- An outline of a mole that becomes notched.
- A spot that changes colour from brown to black or is varied.
- A spot that becomes raised or develops a lump within it.
- The surface of a mole becoming rough, scaly or ulcerated.

How Are Tumors Excised From Complex Areas
Excision of tumors on some parts of the body can be tricky. Tricky areas include the face, ear, scalp, sole of the foot, fingers, and toes. If tumors are excised from these areas, it may not be possible to stretch the skin over the site to close it. Special repairs may be needed.1 Examples of repair procedures are skin grafts or flaps. Margins in these areas may be smaller.3
Am I At Risk Of Skin Cancer
Everyone is at some risk of developing skin cancer. Your risk increases as you grow older. Most skin cancers are caused by over-exposure to the suns ultraviolet radiation.
Your risk of skin cancer increases if you:
- have someone in your family who has had skin cancer
- have had bad sunburn before
- have fair skin
- have many moles on your skin
- spend a lot of time outdoors without sun protection or work outdoors
- have used solariums or sun lamps
- have a compromised immune system or are taking immunosuppression medication
You can also use this online calculator to work out your likely risk of melanoma.

Infiltrative Basal Cell Carcinoma
This photo contains content that some people may find graphic or disturbing.
Infiltrative basal cell carcinoma occurs when a tumor makes its way into the dermis via thin strands between collagen fibers. This aggressive type of skin cancer is harder to diagnose and treat because of its location. Typically, infiltrative basal cell carcinoma appears as scar tissue or thickening of the skin and requires a biopsy to properly diagnose.
To remove this type of basal cell carcinoma, a specific form of surgery, called Mohs, is used. During a Mohs surgery, also called Mohs micrographic surgery, thin layers of skin are removed until there is no cancer tissue left.
This photo contains content that some people may find graphic or disturbing.
Superficial basal cell carcinoma, also known as in situ basal-cell carcinoma, tends to occur on the shoulders or the upper part of the torso, but it can also be found on the legs and arms. This type of cancer isnt generally invasive because it has a slow rate of growth and is fairly easy to spot and diagnose. It appears reddish or pinkish in color and may crust over or ooze. Superficial basal cell carcinoma accounts for roughly 15%-26% of all basal cell carcinoma cases.
Tips For Screening Moles For Cancer
Examine your skin on a regular basis. A common location for melanoma in men is on the back, and in women, the lower leg. But check your entire body for moles or suspicious spots once a month. Start at your head and work your way down. Check the “hidden” areas: between fingers and toes, the groin, soles of the feet, the backs of the knees. Check your scalp and neck for moles. Use a handheld mirror or ask a family member to help you look at these areas. Be especially suspicious of a new mole. Take a photo of moles and date it to help you monitor them for change. Pay special attention to moles if you’re a teen, pregnant, or going through menopause, times when your hormones may be surging.

How Is Skin Cancer Diagnosed
First, your dermatologist may ask you if you have noticed any changes in any existing moles, freckles or other skin spots or if youve noticed any new skin growths. Next, your dermatologist will examine all of your skin, including your scalp, ears, palms of your hands, soles of your feet, between your toes, around your genitals and between your buttocks.
If a skin lesion is suspicious, a biopsy may be performed. In a biopsy, a sample of tissue is removed and sent to a laboratory to be examined under a microscope by a pathologist. Your dermatologist will tell you if your skin lesion is skin cancer, what type you have and discuss treatment options.
What Should I Look For
Not all skin cancers look the same. In fact, skin cancers can show up in many shapes and sizes. Sometimes they might even look like other skin conditions. Many skin cancers are more common on parts of the body that tend to get more sun, such as the face, head, neck, and arms. But skin cancers can occur anywhere on the body.
Some of the more common ways in which skin cancers can appear include:
- A new, expanding, or changing growth, spot, or bump on the skin
- A sore that bleeds and/or doesnt heal after several weeks
- A rough or scaly red patch, which might crust or bleed
- A wart-like growth
- A mole thats new or changing in size, shape, or color
- A mole with an odd shape, irregular borders, or areas of different colors
But its important to understand that these are not the only ways skin cancer can appear. To learn more about what skin cancer might look like, see:

Slop On Spf 30 Or Higher Sunscreen
Sunscreen should not be relied upon as the only form of sun protection.
No sunscreen provides 100% UV protection – remember to use in combination with protective clothing, hats and sunglasses.
Look for a sunscreen that:
- Has a sun protection factor of at least 30
- Is labelled ‘broad spectrum’ – this will filter both UVA and UVB radiation
- Is water resistant – less likely to be washed off by water activities or sweat
- Meets Australian standards – look for ‘AUST L’ or ‘AS/NZS 2604:98’ on the label
- Has a valid expiry date
- Apply sunscreen 20 minutes before planned sun exposure to clean, dry skin
- Layer sunscreen onto exposed skin rather than rubbing it in
- Apply a thick layer of sunscreen – most people do not use enough
- Reapply every two hours or more often if in water, sweating or towel drying
- Remember your lips . A zinc or lip balm will provide longer lasting protection than a cream
Finding Skin Cancer Early
When skin cancer is found and treated early, the chances of successful treatment are better. Get regular health checkups and see your doctor if you have any symptoms or are worried about your health.
If you have a higher than average risk, you may need to visit your doctor more often to check for skin cancer. Talk to your doctor about what can help find skin cancer early including checking your skin and having skin exams by a trained health professional.

Scaly Red Patches Of Skin
Scaly red patches of skin are a telltale early warning sign of squamous cell carcinoma. After basal cell carcinoma, it is one of the most commonly diagnosed types of skin cancer in the United States. A patch of skin like this on your body should be monitored closely. If you’ve been diagnosed with eczema, you may be having a flare-up. But if you’ve ruled out any kind of eczema and your scaly patch of skin isn’t going away, it may be time to see your doctor. In addition, these patches of skin may bleed or ooze and then crust back over repeatedly.

The exact causes of vulvar cancer arent clear. But certain things can raise your chances of getting it. These include:
- Age. More than half of cases are in women over age 70.
- A history of unusual Pap tests
- Lichen sclerosus, a condition that makes vulvar skin thin and itchy
- Smoking, especially if youve also had HPV

How Are Moles Evaluated
If you find a mole or spot that has any ABCDE’s of melanoma — or one that’s tender, itching, oozing, scaly, doesn’t heal or has redness or swelling beyond the mole — see a doctor. Your doctor may want to remove a tissue sample from the mole and biopsy it. If found to be cancerous, the entire mole and a rim of normal skin around it will be removed and the wound stitched closed. Additional treatment may be needed.
How Is Skin Cancer Of The Head And Neck Diagnosed
Diagnosis is made by clinical exam and a biopsy. Basal cell and squamous cell cancers are staged by size and extent of growth. Basal cell cancers rarely metastasize to lymph nodes, but they can grow quite large and invade local structures. Squamous cell cancers have a much higher incidence of lymph node involvement in the neck and parotid gland and can spread along nerves.
Melanoma is staged, based not on size but on how deeply it invades the skin layers. Therefore, a superficial or shave biopsy will not provide accurate staging information used to guide treatment. Melanomas can have a very unpredictable course and may spread to distant organs. Melanomas with intermediate thickness often require sentinel node biopsy, a surgical procedure performed by a head and neck surgeon, to determine if microscopic spreading to lymph nodes has occurred.

When To Use Sun Protection
The best way to know when you need to use sun protection is to use the UV Index. The UV Index is a simple measure of the UV radiation level at the Earth’s surface. It has been designed to help people to avoid overexposure to high levels of UV radiation. The values of the Index range from zero upward and the higher the Index value, the greater the potential for damage to the skin and eyes, and the less time it takes for harm to occur.
You need to use sun protection when the UV Index is 3 or above, and when the UV Index reaches 8 or above you should take extra care and stay out of the sun if this is possible.
A daily UV forecast, including sun protection times, is available for over 600 Australian locations at the Bureau of Meteorology website or at www.MyUV.com.au. Make sure you choose the forecast for your area.
What Should I Expect Before During And After Excision
The best type of doctor and setting for excision will depend on tumor size, location, and type. Thin melanomas and low-risk non-melanoma skin cancers can be excised in a doctors office. A numbing medicine will be injected at the tumor. After the procedure, you will be given instructions on how to care for the incision.
Excision of thicker melanomas may be done at the same time as sentinel lymph node biopsy. This procedure is usually done at the hospital under general anesthesia. Often it is an outpatient surgery, although sometimes patients stay overnight.
