What are the types of skin cancer?
Signs and symptoms of basal cell carcinoma:
Basal cell carcinoma usually occurs in the sun’s exposed areas such as the neck or face.
Basal cell carcinoma can be seen as follows:
Pearl-like, pearly or waxy bump
Plain, flesh-colored or brown-like lesion
Signs and symptoms of squamous cell carcinoma:
Squamous cell carcinoma is most commonly seen in sun-exposed areas of your body, such as face, ears and hands. In humans with darker skin, squamous cell carcinoma is more likely to develop in areas of skin that are not frequently exposed to the sun.
Squamous cell carcinoma can be seen as follows:
Hard, red nodule
Plain lesion with scaly or crustal surface
Findings and symptoms of melanoma:
Melanoma can occur in any part of your body, skin or cancer that does not show any other symptoms. Melanoma is most frequently seen on the face or trunk of the affected men. In women, this type of cancer occurs most often in the calves. Melanoma can occur in skin exposed to sun in both men and women.
Melanoma can be seen in all humans regardless of skin color. In people with darker skin color, melanoma tends to appear under the hands or feet of the feet or under the toenails.
Melanoma’s findings include:
Large brownish stain where dark spots are observed
The color that shows the color, size or feeling changes or the bleeding is observed
Small lesion with irregularly bound and red, white, blue or blue-black sections
Dark lesions in the hand, foot, finger tips, or toes, or in the mucous membranes covering the mouth, nose, vagina, or anus
Symptoms and symptoms of less frequent skin cancers:
Other less common types of skin cancer include:
Kaposi’s sarcoma. This rare type of skin cancer occurs in the blood vessels of the skin and causes red or purple patches on the skin or mucous membranes.
Kaposi’s sarcoma occurs primarily in people with impaired immune system, such as those receiving natural immunosuppressive drugs, such as patients with AIDS and organ transplantation.
Other people who are at increased risk of Kaposi’s sarcoma include young men living in Africa, or older men with Italian or eastern European Jewish heritage.
Merkel cell carcinoma. Merkel cell carcinoma causes hard, bright nodules on the skin or just below the skin and in the hair follicles. Merkel cell carcinoma is most commonly found in the head, neck and trunk.
Oil gland carcinoma. This rare and aggressive cancer originates from the sebaceous glands in the skin. Fatty gland carcinoma, often seen as a hard, painless nodule, may occur anywhere, but it often occurs on the eyelid and is often confused with other eyelid problems.
When should I see a doctor?
Make an appointment with your doctor if you notice any change in your skin that could cause you to worry. All skin changes do not cause cancer. Your doctor will investigate changes in your skin to determine the underlying cause.
What are the skin cancer risk factors?
Factors that increase your skin cancer risk include:
Light skin color. Whatever skin color, everyone can have skin cancer. However, the small amount of pigment (melanin) in your skin provides less protection against harmful ultraviolet radiation. If you have yellow or scarlet hair and colored eyes and easily freckle or sunburn, you have a darker complexion than someone with skin
cancer is more likely to develop.
Sunburn history. The fact that you have had a sunburn in one or more times during childhood or youth increases the risk of developing cancer in adulthood. Sun burns in adults are also a risk factor.
Excessive sun exposure. If the skin is not protected by sunscreen or lotion or an outfit, skin cancer can occur in everyone under the sun. The tanning can also put you at risk, including exposure to solarium devices. Bronze is your skin’s injury response to excessive UV radiation.
Sunny or high-altitude climates. People living in sunny, hot climate areas are exposed to more sunlight than people living in colder climates. Living at high altitudes where sunlight is most powerful will also expose you to more radiation.
Skin moles. The risk of cancer increases in people who have multiple skin eruptions or abnormal skin moles called dysplastic nevus. It is more likely that these abnormal skin moles, which have an irregular appearance and are generally larger than those of normal skin, turn into cancer. If you have a history of abnormal skin moles, watch your moles regularly to see if there are any changes.
Precancerous skin lesions. Having skin lesions known as actinic keratoses may increase your risk of developing skin cancer. These precancerous skin growths generally appear as hard, scaly patches ranging from brown to dark pink. They are commonly seen on the face, heads and hands of light-skinned people with sun damage.
A family history of skin cancer. If your mother or father or your brother has skin cancer in the past, you may increase the risk of this disease.
A history of personal skin cancer. If you have skin cancer once, you have the risk of being reborn.
Weakened immune system. Individuals with weakened immune systems are at higher risk for skin cancer. This includes patients with HIV / AIDS and those using drugs that suppress the immune system after organ transplantation.
Exposure to radiation. People with radiation therapy for skin diseases such as eczema and acne may have an increased risk of skin cancer, especially basal cell carcinoma.
Exposure to certain substances. Exposure to certain substances, such as arsenic, may increase your risk of cancer.
