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.
What Is Skin Cancer And Melanoma
Skin cancer is a disease that occurs when your skin cells grow abnormally, usually from too much exposure to ultraviolet radiation from the sun.
This uncontrolled growth of abnormal cells forms a tumour in the skin. Tumours are either benign , or malignant .
Skin cancer is the most common type of cancer: each year, more than 13,000 Australians are diagnosed with a melanoma and almost 980,000 new cases of non-melanoma skin cancers are treated. Skin cancer is mostly preventable, and there are effective treatment options available.
Skin cancers are named according to the cells in which they form. There are 3 main types:
- Basal cell carcinoma begins in the lower segment of cells of the epidermis your outer layer of skin. These tend to grow slowly, and rarely spread to other parts of the body.
- Squamous cell carcinoma grows from the flat cells found in the top layer of your epidermis. SCC can grow quickly on the skin over several weeks or months. Bowens disease is an early form of SCC that hasnt grown beyond the top layer of skin.
- Melanoma grows from cells called melanocytes cells that give your skin its colour. Melanoma is the rarest type of skin cancer but is considered the most serious because it can spread quickly throughout the body.
BCC and SCC are also called non-melanoma skin cancers. BCC represents more than 2 in 3 non-melanoma skin cancers, and around 1 in 3 are SCC. There are other types of non-melanoma skin cancers, but they are rare.
Basal Cell Carcinoma Staging
Staging;is the process of determining whether cancer has spread and, if so, how far. The stage of the disease may affect the treatment plan.
The stage is based on the size of the tumor, how deeply into the skin it has grown, and whether cancer has spread beyond the tumor to the lymph nodes. Your doctor will look at the results of the biopsy to determine the stage.;In rare cases, your doctor may recommend imaging such as CT or PET-CT scan to see if the cancer has spread beyond the skin
Stages are numbered in Roman numerals between 0 and IV.
Most non-melanoma skin cancers are Stage 0 or Stage 1. Stage 3 and 4 are relatively rare. Based on the type of cancer, the stage of cancer, your overall health, and other factors, your doctor works with you to develop a treatment plan.
High risk features for primary tumor staging
- Depth/invasion: >2 mm thickness , Clark level IV, Perineural invasion
- Anatomic: Primary site ear

Skin Cancer Diagnosis & Treatment
On skin cancer diagnosis, Dr. Truong says, To the untrained eye, skin cancer can mimic the appearance of natural irregularities or other common skin conditions. The deadliest form of skin cancer, melanoma, may look like a mole, therefore, it is very important to note new growths or changing lesions, and to bring them to the attention of your dermatologist. A skin biopsy may be needed for a definitive diagnosis.
Once a patient receives a definitive skin cancer diagnosis, treatment planning begins. The treatment depends on the type of skin cancer, the size, location, and level of aggressiveness. The main methods of treatment include surgery, radiation, and light-based treatments.
Surgery is the most common and effective treatment for most skin cancers. Depending on the size, aggressiveness, and location of the skin cancer, a wide local excision or Mohs micrographic surgery may be recommended. Both surgeries are minimally invasive and usually done under local anesthesia. Mohs Micrographic Surgery is a specialized skin cancer surgery designed to remove skin cancers on sensitive areas such as the head and neck. The surgery removes skin cancer completely while preserving as much healthy skin as possible. The cancerous lesion is removed layer by layer, and the margins of each specimen are examined by your Mohs surgeon while you wait. Due to the on-site 100% margin evaluation, cure rates are superior and more healthy skin can be preserved, minimizing the scar.
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.

Laser Surgery Is Not Fda
Laser surgery is not currently used as a standard treatment for basal cell carcinoma or squamous cell carcinoma. It can, however, be an effective secondary treatment. Laser treatment is sometimes used after Mohs surgery to complete the removal of cancer cells. Lasers are effective at removing precancerous lesions, but have not been proven effective at treating cancer yet.;
Symptoms Of Skin Cancer
The first sign you notice may be a change in how an area of skin looks. This may be on any area of skin but usually affects an area of skin that gets a lot of exposure to the sun.;
There are different symptoms of skin cancer. If you have any of these or notice any changes in your skin, it is important to have them checked by your GP.

How To Check Yourself For Skin Cancer
The SCF;recommends that people conduct skin self-exams at least once a month or more if you have risk factors such as an inherited gene that predisposes toward skin cancer, or if you have spent a lot of time in the sun.
This check, which should be done in a well-lit room with a floor-length mirror and a hand mirror, should not take long once you get the hang of it.
Youll need to examine every inch of your skin, from your scalp to the bottoms of your feet and nails. A;self-exam body map;can help keep track of whats normal for you and whats not.
The more often you do these self-exams, the more familiar you will be with every freckle, mole, sore, lump, and blemish on your body and the better you will be at recognizing potential trouble in the form of new markings or changes in the size, shape, or color of existing spots.
Overall, heres the bottom line on what you should be looking for, according to the American Academy of Dermatology : a mole or skin lesion that changes in size, shape, or color, as well as spots that itch or bleed. Also watch for a new growth or a sore that doesnt heal.
Knowing your body and all of its unique spots is the first step in knowing what to look for when it comes to early signs and symptoms of skin cancer.

Red Flags For Squamous Cell Carcinoma
Like basal cell cancer, squamous cell cancer tends to develop on parts of the body that get a lot of sun, such as the face, neck, ear, lip, and back of the hands.
It might also appear in scars or skin sores anywhere on the body
While squamous cell carcinoma can look like a flat area closely resembling healthy skin, there may be clearer signs of malignancy, according to the SCF, including:
- Rough or scaly red patches that may bleed or crust
- Raised growths or lumps, sometimes with a depression in the center
- Open sores, possibly with oozing or crusted areas, that dont heal or that go through cycles of healing and bleeding
- Growths that resemble warts
Certain skin conditions may be precursors to squamous cell carcinoma, or even early forms of it:

Focus On Eyelid Skin Cancers: Early Detection And Treatment
Your eyes can focus on a tiny splinter in the finger of a squirming child, a stop sign in the distance or stars blinking light-years away. You can roll your eyes, flirt with them, do a double-take and express joy or despair without words. When you think about how amazing your eyes are, wouldnt you do anything to protect them?
Strong bony sockets called orbits encase and safeguard your eyes. The thin tissue surrounding them, however, including your upper and lower eyelids, is extremely vulnerable to damage from the suns ultraviolet rays. Because of that, nonmelanoma skin cancers on and around the eyelids are common.
A big hat and UV-blocking sunglasses can help, and so can sunscreen if you actually use it around your eyes. Many people stop short of the eye area when applying products, mainly because of sensitivity concerns. Even among those who use sunscreen on their faces regularly, the most often-missed spots are around the eyelids, according to a small British study. For advice on what type of sunscreen to use around your eyes, see this Ask the Expert article.
What Are The Signs And Symptoms Of Skin Cancer
The most common warning sign of skin cancer is a change on the skin, typically a new mole, a new skin lesion or a change in an existing mole.
- Basal cell carcinoma may appear as a small, smooth, pearly, or waxy bump on the face, or neck, or as a flat, pink/red- or brown-colored lesion on the trunk, arms or legs.
- Squamous cell carcinoma can appear as a firm, red nodule, or as a rough, scaly, flat lesion that may itch, bleed and become crusty. Both basal cell and squamous cell cancers mainly occur on areas of the skin frequently exposed to the sun, but can occur anywhere.
- Melanoma usually appears as a pigmented patch or bump. It may resemble a normal mole, but usually has a more irregular appearance.
When looking for melanoma, think of the ABCDE rule that tells you the signs to watch for:
- Asymmetry: The shape of one half doesn’t match the other.
- Border: Edges are ragged or blurred.
- Color: Uneven shades of brown, black, tan, red, white or blue.
- Diameter: A significant change in size .
- Evolution: Changes in the way a mole or lesion looks or feels .
Skin Cancer Can Look Like Many Things; Therefore People Can Go Long Periods Of Time Without Recognizing That They Have A Skin Cancer Says Dr Steven Musick Md A Board Certified Dermatologist Who Runs Musick Dermatology Llc In Swansea Il Which Provides State
Not only can skin cancer mimic many benign conditions such as pimples and skin barnacles, but a tumor can develop in areas that are difficult to inspect or that are not considered during a persons self-skin exam.
For example, it would be difficult for one to examine their scalp unless theyre bald. Inside the ears is another hard-to-visualize location.
And then there are areas that people wouldnt think to check, such as between their butt cheeks, inside their belly button, between their toes, the soles of their feet and even the pupils of their eyes.
Yes, melanoma can grow in the pupils and go unnoticed for long periods of time.
Melanoma, along with squamous cell carcinoma, can also pop up internally, including within the genitals, mouth, nose and lungs.
Another factor that influences how long a person can have skin cancer and not know it is where they live.
If they live in a Third, and especially Fourth, World nation, they can have a basal cell carcinoma that goes undiagnosed for many years due to lack of skin cancer awareness campaigns and adequate skin cancer screenings.
However, this type of tumor will continue progressing, though very slowly; it wont stop growing just because its untreated.

Lasers And Lights Can Improve Rosacea
Laser treatment is the best option to treat rosaceas redness. Its even more effective than medication. Its especially helpful for people with skin thickening around the nose. A series of at least two laser treatments is needed for maximum results and as many as eight treatments may be needed for more severe rosacea.
Recovery After Eyelid Surgery
Some patients may need to wear an eye patch for a few days. Swelling and bruising are common after surgery around the eyes. I tell all my patients who have surgery near the eye that theyll probably have a black eye afterwards. If they dont, theyll be pleasantly surprised. If the surgery was on the upper eyelid, I warn them that it may swell shut. Sleeping with the head elevated can help. And thanks to gravity, swelling goes away fairly quickly within a few days.
It takes six months to a year for a scar to heal completely, Dr. Ratner explains. Some patients may develop a hypertrophic, or raised, scar, especially on the lower eyelids, because when you blink or raise your eyebrows, the body feels that tension and pulls back. But we have procedures, such as steroid injections, that can flatten out thickened scars if they become uncomfortable or noticeable.
Warning Signs of Skin Cancer on the Eyelids
- A basal cell carcinoma extending toward the margin of the lower eyelid. Early lesions may be subtle, so its important to be alert to changes in the skin around the eyes.
- A subtle pearly lesion in the middle of the lower eyelids lash line is a BCC.
- This crusty spot near the eye was diagnosed as a squamous cell carcinoma .
- This horn-shaped growth on the lower eyelid, known as a cutaneous horn, is an SCC.

Skin Cancer Undiagnosed For Over 10 Years
The patient had neglected his illness for more than 10 years, says a case report in the International Open Access Journal of the American Society of Plastic Surgeons .
The patient was a man, 48, living in a U.S. city. The medical attention was sought out due to the insistence of a family member, continues the paper.
The cancer was basal cell carcinoma that had grown to 10 centimeters on his scalp. Somehow this patient didnt mind living with an ulcerating, oozing and bleeding growth on his head.
Had he not sought treatment, he could have lived many more years barring death from an unrelated cause such as a heart attack or car accident.
With that all said, there is no data on what the record is for how long a person lived with an undiagnosed skin cancer.
Certainly you can imagine there must be many cases of people all over the world, living in undeveloped societies with scant medical care, let alone skin cancer awareness, whove been living for over 20 years with a slowly growing bump or patch.
This would describe basal cell carcinoma.
But a person will not get away for too long with an undiagnosed melanoma, as it WILL spread and cause symptoms of that spread, such as respiratory problems or ongoing severe headaches .
