Basal cell cancer is the most common form of cancer in the United States. Most skin cancers are basal cell cancer.

Other common types of skin cancer are:

Basal cell carcinoma

If you're like many Americans, you've spent hours in the sun trying to get the perfect, golden tan. But tanning has its downsides, including an increased risk of skin cancers like basal cell carcinoma. Most people who get skin cancer have the basal cell carcinoma form. The good news is that this type of skin cancer grows very slowly compared to the more dangerous melanoma type. The bad news is, it's still cancer. You're more likely to get basal cell carcinoma on the parts of your skin that are exposed to the sun, like your scalp, if you don't wear a hat when you go outside. People who are fair-skinned, with blonde hair and blue eyes are also at greater risk for skin cancer than those with darker skin. To find out if you may have basal cell carcinoma, first, do a skin check. Look in a mirror and check your body for any bumps that look white, pink, or brown, or that have crusted over and bleed but don't heal. If you spot anything unusual on your skin, see your dermatologist. The doctor can perform a biopsy removing some or all of the growth and sending it to a lab where it can be checked for cancer. Basal cell carcinoma doesn't grow very quickly, and it's not likely to spread. Your doctor should be able to remove the bumps by cutting, scraping, or freezing it off. Once the cancer is removed, there's a good chance you'll be cured. But because skin cancer can come back, you always want to keep a close eye on your skin, and call your doctor if you notice any new growths. A lot of diseases are beyond your control, but skin cancer is one condition you do have some control over. The best way to avoid getting it is to stop sun worshipping. Seek shade during the hours when the sun is strongest, usually from 10 a.m. to 4 p.m. and especially during the summer months. If you do have to be outside then, slather on a thick layer of sunscreen with an SPF of at least 30, one that protects against both UVA and UVB rays. Reapply it often, if you're in the water where the sunscreen can wash off. Also wear a wide-brimmed hat, sunglasses, and long sleeves. If you want a healthy glow, get one from a bottle. Rubbing on a tanning cream is safer than exposing your skin to the sun.

Skin cancer, basal cell carcinoma - nose

The typical basal cell skin cancer appears as a small, pearly, dome-shaped nodule with small visible blood vessels (telangiectasias).

Skin cancer, basal cell carcinoma - pigmented

This skin cancer appears as a 2 to 3 centimeter skin spot. The tissue has become destroyed (forming an atrophic plaque). There is a brownish color because of increased skin pigment (hyperpigmentation) and a slightly elevated, rolled, pearl-colored margin. This growth is located along the hair line.

Melanoma

You've noticed a mole, sore, or growth on your skin that doesn't look right. It might be a melanoma and time to see a doctor. Melanoma is skin cancer caused by changes in cells called melanocytes. These cells make a skin pigment called melanin. Melanin's what gives you your skin and hair color. Melanoma can appear on normal skin, or it may begin as a mole or other area that has changed in appearance. Some moles you have when you're born can develop into melanoma. There are four types, superficial spreading melanoma is the most common. It's usually flat and irregular in shape and color, with different shades of black and brown. It's most common in Caucasians. Nodular melanoma usually starts as a raised area that is dark blackish-blue or maybe bluish-red. Lentigo melanoma usually occurs in older adults. It's more common on sun-damaged skin on your face, neck, and arms. It's usually large, flat, and tan, with areas of brown. Lastly, acral lentigenous melanoma is the least common form. It usually occurs on your palms, soles, or under your nails. And it's more common in African-Americans. The risk of developing melanoma increases with age, but it is often also seen in young people. You are more likely to get melanoma if you have fair skin, blue or green eyes, or red or blond hair. People who live in sunny climates or at high altitudes are also at risk. As are people who spend a lot of time in the sun, or had one or more blistering sunburns during childhood, or use tanning devices. So, how do you know you have melanoma? You may have a mole, sore, lump, or growth on your skin that just doesn't look right. You may notice a sore or growth that bleeds or changes color. One half of the growth may be different from the other. The edges of the growth may be irregular. The color of the growth may change from one area to another. The spot may be larger than 6mm in diameter, about the size of a pencil eraser. The mole may keep changing in appearance. So, what do you do about melanoma? To treat melanoma successfully, you have to recognize the symptoms early. Make sure somebody sees all of your skin at least once a year and pay attention to your own skin. Call your doctor if you notice anything unusual. Your doctor will examine your skin for size, shape, color, and texture of any suspicious areas. If your doctor thinks you may have skin cancer, you'll have a piece of skin removed and sent to a laboratory for testing. This is called a biopsy. You may also have a lymph node biopsy to see if the cancer has spread to nearby lymph nodes. If you are diagnosed with melanoma, you may have other tests to see if the cancer has spread further. You will need surgery if you have melanoma. The doctor will remove the skin cancer and some of the surrounding tissue. If the cancer has spread to nearby lymph nodes they will also be removed. After surgery, you may need medicine called interferon. If the cancer has spread to organs, it may not be able to be cured. Treatment then might focus on shrinking the cancer and making you as comfortable as possible. You may need chemotherapy, immunotherapy, radiation treatment, and more surgery. Caught early, some of the types of melanoma can be cured. Melanoma that is very deep or has already spread to lymph nodes is more likely to return after treatment. And the odds are even worse if it has spread farther to other organs. If you have melanoma and recovered, it's important you continue to examine your body for any unusual changes because the cancer may return many years later. One more reason that the earlier you catch it the better.

Skin cancer, basal cell carcinoma - behind ear

This skin cancer appears as a 1 to 1.5 centimeter flesh-colored nodule with a central depression and a raised, pearly border. Small blood vessels are visible (telangiectatic).

Sun's effect on skin

The skin uses sunlight to help manufacture vitamin D, which is important for normal bone formation. But there’s a downside. The sun's ultraviolet light can cause major damage to the skin. The outer layer of the skin has cells that contain the pigment melanin. Melanin protects skin from the sun's ultraviolet rays. These can burn the skin and reduce its elasticity, leading to premature aging. People tan because sunlight causes the skin to produce more melanin and darken. The tan fades when new cells move to the surface and the tanned cells are sloughed off. Some sunlight can be good as long as you have proper protection from overexposure. But too much ultraviolet, or UV, exposure can cause sunburn. The UV rays penetrate outer skin layers and hit the deeper layers of the skin, where they can damage or kill skin cells. People, especially those who don’t have much melanin and who sunburn easily, should protect themselves. You can protect yourself by covering sensitive areas, wearing sunblock, limiting total exposure time, and avoiding the sun between 10 am and 2 pm. Frequent exposure to ultraviolet rays over many years is the chief cause of skin cancer. And skin cancer should not be taken lightly. Check your skin regularly for suspicious growths or other skin changes. Early detection and treatment are key in the successful treatment of skin cancer.

Skin cancer, basal cell carcinoma - spreading

This skin cancer, a basal cell carcinoma, is 5 to 6 centimeters across, red (erythematous), with well defined (demarcated) borders and sprinkled brown pigment along the margins. This cancer is located on the person's back.

Multiple Basal cell cancer due to x-ray therapy for acne

Basal cell carcinomas are more prevalent on sun or radiation exposed areas of skin. Here the typical lesion with raised, rolled, pearly borders with ulcerated center is seen on the back of a person previously irradiated for acne.

Basal Cell Carcinoma - face

This flesh-colored, verrucal, pearly, smooth, non-scaling papule is a basal cell carcinoma. It is occurring in a common, sun-exposed area of the face, on the forehead.

Basal cell carcinoma - close-up

This basal cell carcinoma appears as a multicolored flat lesion, with a periphery that has ulcerated and bled. Telangiectasia are present.

Basal cell cancer

Basal cell cancer is a malignant skin tumor involving cancerous changes of basal skin cells. Basal cell skin cancers usually occur on areas of skin that are regularly exposed to sunlight or other ultraviolet radiation. Once a suspicious lesion is found, a biopsy is needed to prove the diagnosis of basal cell carcinoma. Treatment varies depending on the size, depth, and location of the cancer. Early treatment by a dermatologist may result in a cure rate of more than 95%, but regular examination by a health care provider is required to watch for new sites of basal cell cancer.
