How To Tell If You Have Skin Cancer

Less Common Skin Cancers

How to Know if it is Skin Cancer?

Uncommon types of skin cancer include Kaposi’s sarcoma, mainly seen in people with weakened immune systems; sebaceous gland carcinoma, an aggressive cancer originating in the oil glands in the skin; and Merkel cell carcinoma, which is usually found on sun-exposed areas on the head, neck, arms, and legs but often spreads to other parts of the body.

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.

Should I Use A Skin Cancer Detection App

Anything that reminds you to look for signs of skin cancer is a good thing. However, some smartphone apps claim to be able to assess certain skin changes and inform individuals whether such changes warrant a visit to a dermatologist for further analysis.

Thus far, the accuracy of these is not high enough and relying solely on an app, rather than on your own observations and visits to a doctor, you could put yourself at risk by delaying a visit to the doctor when one is warranted. In one recent study, the most accurate skin cancer detection app missed almost 30% of melanomas, diagnosing them as low-risk lesions.

However, these apps are evolving, and one day they could become part of the arsenal to help detect skin cancer.;Smartphones can be useful in terms of telemedicine. For instance, in locations where dermatologists may not be readily available, a local physician can send a photo of a suspicious mole to a dermatologist and based on visual inspection and communication with that physician, determine what steps to take next.

What You Need To Know About Early Detection

Finding melanoma at an early stage is crucial; early detection can vastly increase your chances for cure.

Look for anything new,changing or unusual on both sun-exposed and sun-protected areas of the body. Melanomas commonly appear on the legs of women, and the number one place they develop on men is the trunk. Keep in mind, though, that melanomas can arise anywhere on the skin, even in areas where the sun doesnt shine.

Most moles, brown spots and growths on the skin are harmless but not always. The ABCDEs and the;Ugly Duckling sign can help you detect melanoma.

Early detection makes a difference

99%5-year survival rate for patients in the U.S. whose melanoma is detected early. The survival rate drops to 66% if the disease reaches the lymph nodes and27% if it spreads to distant organs.

Basal Cell Carcinoma Staging

How You Know If You Have Skin Cancer

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.

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:

Identify An Ugly Duckling

Just because a mole is, well, ugly, doesnt mean its cancerous. However, most normal moles on the body look alike. Any mole that sticks out among the others on your body in any way, is an Ugly Duckling and should be examined further, says Dr. McNeill. Perhaps the offender is bigger than the rest. Maybe its darker than your other moles. Or perhaps its the sole raised mark. No matter what, if its different, have a dermatologist check it out.

Be Attuned To Any Visible Change

A change in a moles shape, size, or color indicates that melanoma may be brewing, notes Dr. Harvey. An uptick in mole elevation raises red flags, too, since that suggests vertical growth beneath the surface of the skin. In fact, a new bump may point to nodular melanoma, the second most common type of melanoma, accounting for 10% to 30% of all cases. Remember, skin cancer can resemble something as nondescript as a pimple or red patch, so its important to check your skin often and take note of all changes, says Dr. McNeill.

The Warning Signs Of Skin Cancer

5 Warning Signs You May Have Skin Cancer

Skin cancers — including melanoma, basal cell carcinoma, and squamous cell carcinoma — often start as changes to your skin. They can be new growths or precancerous lesions — changes that are not cancer but could become cancer over time. An estimated 40% to 50% of fair-skinned people who live to be 65 will develop at least one skin cancer. Learn to spot the early warning signs. Skin cancer can be cured if it’s found and treated early.

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.

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.

Signs That Your Mole Can Be Suspicious

If your mole starts to show some strange characteristics, it is probably time to ask a doctors opinion. Visit your doctor if your mole:

  • develops a crust or a scab
  • sometimes bleeds
  • is getting bigger or swelling
  • is strangely shaped
  • has borders that are irregular
  • includes lots of different colours or shades
  • is bigger than the size of a pencil eraser in diameter
  • has appeared recently

Non-melanoma skin cancer symptoms

While melanoma is the most dangerous form of skin cancer, it is still important to pay attention to non-melanoma skin cancers and understand the forms they can take.

According to the UK National Health Service, one of the first non-melanoma skin cancer symptoms is a persisting lump or discolored patch on the skin that doesnt heal after a few weeks and keeps progressing over months or even years. The two most common types of non-melanoma skin cancer are basal cell carcinoma and squamous cell carcinoma. Find out how to identify these types of skin cancer below.

Any new spots that appear on the skin could potentially be skin cancer, considering that one in five people will develop at least one skin cancer in their lifetime. Definitively distinguishing the different types of skin cancer requires a biopsy and microscopic evaluation, but the general appearance of these tumors also differs to some degree.

  • Basal cell carcinomas are often shiny;and have been described as “pearlescent.” They may be flat, raised, or dome-shaped, and are often pink, pale, or flesh-colored. On careful inspection, tiny blood vessels may be visible when compared with the surrounding skin. Basal cell cancer characteristically is very often ulcerated and has been called a rodent ulcer because it looks like a mouse has gnawed it.

  • Squamous cell carcinomas are often raised and feel crusty to touch. They can appear scaly and may be ulceratedthat is, have a central depression that is lighter and flatter than the surrounding area. These cancers sometimes bleed, ooze, or form scabs.

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:

Remember, melanoma can be cured if detected early, unlike many cancers. So knowing your risk factors and communicating them to your healthcare provider may help you make more informed lifestyle and health care choices. If you have multiple moles or other risk factors, it is important that you perform regular self-examinations of your skin, see a dermatologist for regular examinations, and protect yourself from the sun.

Squamous Cell Carcinoma Signs And Symptoms

Like basal cell carcinoma, squamous cell carcinoma usually occurs because of repeated sun exposure over time. This skin cancer is a slow-developing skin cancer that can spread to other areas of the skin, although it is still considered uncommon to spread widely.

Squamous cell carcinoma normally takes the form of:

  • wart-like bumps that often have crusted surfaces
  • rough, scaly patches that may bleed
  • an open sore that bleeds or develops a crust
  • red, dome-like nodules

Bowens disease, also known as squamous cell carcinoma in situ, is an early form of squamous cell carcinoma. It usually appears as a red, itchy scaly patch that can often be confused for psoriasis or eczema. It is easily treated, but if left undiagnosed, it can pose a risk.

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.

How To Spot Skin Cancer

Skin cancer;is by far the most common type of cancer. If you know what to look for, you can spot warning signs of skin cancer early. Finding it early, when its small and has not spread, makes skin cancer much easier to treat.

Some doctors and other health care professionals include skin exams as part of routine health check-ups. Many doctors also recommend that you check your own skin about once a month. Look at your skin in a well-lit room in front of a full-length mirror. Use a hand-held mirror to look at areas that are hard to see.

Use the ABCDE rule to look for some of the common signs of;melanoma, one of the deadliest forms of skin cancer:

AsymmetryOne part of a mole or birthmark doesnt match the other.

BorderThe edges are irregular, ragged, notched, or blurred.

ColorThe color is not the same all over and may include shades of brown or black, sometimes with patches of pink, red, white, or blue.

DiameterThe spot is larger than ¼ inch across about the size of a pencil eraser; although melanomas can sometimes be smaller than this.

EvolvingThe mole is changing in size, shape, or color.

Basal and squamous cell skin cancers;are more common than melanomas, but they are usually very treatable.

Both basal cell carcinomas and squamous cell carcinomas, or cancers, usually grow on parts of the body that get the most sun, such as the face, head, and neck. But they can show up anywhere.;

Causes Of Skin Cancer

How to tell if you have skin cancer

Different forms of skin cancer develop when there are mutations in the DNA of skin cells. Skin cancer begins with a mutation in the epidermis, which is the top layer of the skin. Cells begin to multiply and grow out of control, eventually forming a cancerous mass.

While various risk factors have been identified, it is not always apparent what factor actually causes skin cell DNA to mutate.

One cause of skin cancer that is clear is exposure to sunlight . The ultraviolet rays in sunlight and tanning beds can cause extensive damage to the DNA in skin cells. In turn, these damaged cells may someday become cancerous. Harmful UV radiation can occur relatively soon before the appearance of skin cancer, but it can also pre-date a cancer diagnosis by many years.

However, UV radiation cant explain skin cancers that occur on body parts that arent exposed to the sun. This suggests that different causes exist for certain cases of skin cancer. Among these causes, for instance, may be a drastic or repeated exposure to toxic substances.

In some cases, a person may inherit genes that lead to melanoma. Certain gene changes received from a parent could cause a failure in the body to control unruly cell growth, eventually resulting in melanoma. These inherited, or familial, melanomas are relatively rare.
