What Causes Skin Lesions
The most common cause of a skin lesion is an infection on or in the skin.
One example is a wart. The human papillomavirus , which causes warts, is passed from one person to another through direct skin-to-skin contact. The herpes simplex virus, which causes both cold sores and genital herpes, is also passed through direct contact.
A systemic infection, which is an infection that occurs throughout your body, can cause skin lesions all over your body. Examples include chickenpox and shingles. MRSA and cellulitis are two potentially life threatening infections that involve skin lesions.
Some skin lesions, such as moles and freckles, are hereditary. Birthmarks are lesions that exist at the time of birth.
Others can be the result of an allergic reaction, such as allergic eczema and contact dermatitis. Some conditions, such as poor circulation or diabetes, cause skin sensitivity that can lead to lesions.
Birthmarks are primary skin lesions, as are moles and acne. Other types include the following.
Squamous Cell Carcinoma Signs And Symptoms
Generally found on the ears, face and mouth, squamous cell carcinoma can be more aggressive than basal cell. Untreated, it may push through the skin layers to the lymphatic system, bloodstream and nerve routes, where it can cause pain and symptoms of serious illness.
Appearance
Squamous cell cancer often starts as a precancerous lesion known as actinic keratosis . When it becomes cancerous, the lesion appears raised above the normal skin surface and is firmer to the touch. Sometimes the spot shows only a slight change from normal skin.
Other signs include:
- Any change, such as crusting or bleeding, in an existing wart, mole, scar or other skin lesion
- A wart-like growth that crusts and sometimes bleeds
- A scaly, persistent reddish patch with irregular borders, which may crust or bleed
- A persistent open sore that does not heal and bleeds, crusts or oozes
- A raised growth with a depression in the center that occasionally bleeds and may rapidly increase in size
What Does Squamous Cell Carcinoma Look Like
Like basal cell carcinoma, SCC is most likely to appear on sun-exposed areas of the body, such as the face, lips, ears, scalp, shoulders, neck, hands, and forearms. But it can occur in other areas, like the genitals, too, according to the Skin Cancer Foundation. Look for scaly red patches; wart-like growths; raised bumps with a central depression; or open sores that crust over, itch, or bleed. For darker skinned individuals, SCC is still scaly, but often brown or black in color, notes Dr. Harvey.

How To Check Yourself
By checking your skin regularly, you will learn to recognize what spots, moles, and marks are already present and how they typically appear. The more you get to know your skin, the easier it will be for you to detect changes, such as new lesions or spots and moles that have changed in shape, size, or color, or have begun bleeding.;
It is best to use a full-length mirror when checking your skin for changes or early signs of skin cancer. Observe your body in the mirror from all anglesfront, back, and on each side.
Taking each part of the body in turn, start with your hands and arms, carefully examining both sides of the hands and the difficult to see places like the underarms. Move on to your legs and feet, making sure to check the backs of your legs, soles of your feet, and between your toes.;
Use a small mirror to get a closer look at your buttocks and your back. You can also use a small mirror to examine your face, neck, head, and scalp. Don’t forget to part your hair and feel around your scalp.

Physical Exam |
The dentist is going to inspect your mouth and lips and will look for any sores, lumps, or white patches present inside your cheeks or underneath your tongue. |
|
Tissue Biopsy |
If the dentist finds an area that looks suspicious then he is going to scrape some of the cells present in that area using a brush and send them to the laboratory for a biopsy to determine whether the abnormal cells are cancerous or not. |
|
Further Tests |
Once the diagnosis of mouth cancer has been confirmed, the doctor is going to perform further tests to determine the stage of the cancer. These tests include:

Cancerous: Basal Cell Carcinoma
What it is: Basal cell carcinomas are usually found on sun-exposed areas, such as the face and neck. They also tend to grow so slowly that they rarely cause any harm.
What it looks like: According to Dr. Rosen, basal cells look like a raised bump on the skin or a red scaly patch that doesnt go away. How its treated: Some basal cell carcinomas can be treated with a cream thats applied daily for several weeks, while others are below the surface and need to be surgically removed. Basal cell carcinoma is really curable, says Dr. Rosen, but it can leave you with a scar that can be quite noticeable.

Basal Cell Carcinoma Early Stages
Basal cells are found within the skin and are responsible for producing new skin cells as old ones degenerate. Basal cell carcinoma starts with the appearance of slightly transparent bumps, but they may also show through other symptoms.
In the beginning, a basal cell carcinoma resembles a small bump, similar to a flesh-colored mole or a pimple. The abnormal growths can also look dark, shiny pink, or scaly red in some cases.
What Do The Early Stages Of Skin Cancer Look Like
People can have stages of skin cancer and yet not feel ill, which makes early treatment and diagnosis a little challenging.

DermNet NZ
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.
What Are The Symptoms Of Skin Cancer
Talk to your doctor if you notice changes in your skin such as a new growth, a sore that doesnt heal, a change in an old growth, or any of the A-B-C-D-Es of melanoma.
A change in your skin is the most common sign of skin cancer. This could be a new growth, a sore that doesnt heal, or a change in a mole.external icon;Not all skin cancers look the same.
For melanoma specifically, a simple way to remember the warning signs is to remember the A-B-C-D-Es of melanoma
- A stands for asymmetrical. Does the mole or spot have an irregular shape with two parts that look very different?
- B stands for border. Is the border irregular or jagged?
- C is for color. Is the color uneven?
- D is for diameter. Is the mole or spot larger than the size of a pea?
- E is for evolving. Has the mole or spot changed during the past few weeks or months?

The Five Stages Of Skin Cancer
Cancer in the skin thats at high risk for spreading shares features with basal cell carcinoma and squamous cell carcinoma. Some of these features are:
- Not less than 2 mm in thickness
- Has spread into the inner layers of the skin
- Has invaded skin nerves
Stage 0
In the earliest stage, cancer is only present in the upper layer of the skin. You may notice the appearance of blood vessels or a dent in the center of the skin growth. There are no traces of malignant cells beyond this layer.
Stage 1
At stage 1, cancer has not spread to muscles, bone, and other organs. It measures roughly 4/5 of an inch. Theres a possibility that it may have spread into the inner layer of the skin.
Stage 2
In this stage, cancer has become larger than 4/5 of an inch. Cancer still has not spread to muscles, bone, and other organs.
Stage 3
At stage 3, the cancer is still larger than 4/5 of an inch. Facial bones or a nearby lymph node may have been affected, but other organs remain safe. It may also spread to areas below the skin, such as into muscle, bone, and cartilage but not far from the original site.
Stage 4
Cancer can now be of any size and has likely spread into lymph nodes, bones, cartilage, muscle, or other organs. Distant organs such as the brain or lungs may also be affected. In rare cases, this stage might cause death when allowed to grow and become more invasive.
Breast Lumps Or Thickening
The earliest symptoms of breast cancer are easier to feel than see. Performing a monthly self-exam of your breasts will help you get familiar with their normal look and feel.
Theres no evidence that self-exams will help you detect cancer earlier, but it will help make it easier for you to notice any changes in your breast tissue.
Get into a routine of examining your breasts at least once per month. The best time to examine your breasts is a few days after the start of your menstrual cycle. If youve already begun menopause, choose a specific date to check your breasts every month.
With one hand positioned on your hip, use your other hand to run your fingers over both sides of your breasts, and dont forget to check underneath your armpits.
If you feel a lump or thickness, its important to realize that some women have thicker breasts than others and that if you have thicker breasts, you may notice lumpiness. A benign tumor or cyst can also cause lumpiness.
Even though it might be not be cause for alarm, tell your doctor about anything you notice that seems unusual.

Basal Cell Skin Cancer Warning Signs
Basal cell cancer tends to develop on parts of the body that get a lot of sun exposure, like the face, head, and neck, but they can appear anywhere.
Some are flat and look a lot like normal skin. Others have more distinctive characteristics, says the American Cancer Society , including:;
- Flat, firm, pale, or yellow areas that resemble a scar
- Raised, reddish patches of skin that might be itchy or irritated
- Small bumps that might be pink, red, pearly translucent, or shiny, possibly with areas of blue, brown, or black
- Pink growths with slightly raised edges and an indentation in the center; tiny blood vessels might run through it like the spokes of a wheel
- Open sores, possibly with oozing or crusted areas, that dont heal or that go through cycles of healing and bleeding
- Delicate areas that bleed easily. For instance, having a sore or cut from shaving that lingers longer than one week.
These slow-growing skin cancers can be easy to ignore unless they become big and begin to itch, bleed, or even hurt, according to the;ACS.
What Does Early Skin Cancer Look Like
It can be challenging to tell if a skin change is unimportant or, in fact, is a sign of developing skin cancer. Skin cancer is not uncommon, as one in five Americans will develop skin cancer before age 70. Learning to spot the warning signs is vital. When identified early, skin cancer is highly curable. Do you know what to look for or when to seek medical advice?

How Is Cancer On The Scalp Treated
Potential treatments for skin cancer on your scalp include:
- Surgery. Your doctor will remove the cancerous growth and some of the skin around it, to make sure that they removed all the cancer cells. This is usually the first treatment for melanoma. After surgery, you may also need reconstructive surgery, such as a skin graft.
- Mohs surgery. This type of surgery is used for large, recurring, or hard-to-treat skin cancer. Its used to save as much skin as possible. In Mohs surgery, your doctor will remove the growth layer by layer, examining each one under a microscope, until there are no cancer cells left.
- Radiation. This may be used as a first treatment or after surgery, to kill remaining cancer cells.
- Chemotherapy. If your skin cancer is only on the top layer of skin, you might be able to use a chemotherapy lotion to treat it. If your cancer has spread, you might need traditional chemotherapy.
- Freezing. Used for cancer that doesnt go deep into your skin.
- . Youll take medications that will make cancer cells sensitive to light. Then your doctor will use lasers to kill the cells.
The outlook for skin cancer on your scalp depends on the specific type of skin cancer:
