Since there are no general screening guidelines for skin cancer, most people should recognize the signs and symptoms of the disease and detect them as early as possible. Squamous cell carcinoma can produce scaly skin lesions such as warts with depression in the center. Organic cell carcinoma is sometimes a white, pearly, or flesh-colored waxy lump, which can cause ulcers. This article explains in detail the types, symptoms, and causes of skin cancer.
the cause of skin cancer
Although the cause of skin cancer is not yet clear, risk factors include exposure to sunlight, sunburn, exposure to environmental chemicals and other substances, treatment for some medical conditions or medical problems, and smoking. The family history of skin cancer and some genetic syndrome can increase the risk, and genetic factors are known to play an important role in the development of many non-melanoma and melanoma skin cancers.
1. Age
Non-melanoma skin cancer generally increases with age, but melanoma is usually found in young people.
2. Skin color and race
Skin tone can be an important risk factor for skin cancer. People with fine skin are at the highest risk because melanin pigment provides some protection from ultraviolet rays but is less than people with dark skin. People with all skin colors can get skin cancer. But diseases are more common in whites than in blacks, and on the contrary, blacks are more likely to die from diseases. This increased risk of death is due to increased difficulty in detecting the condition of people with dark skin.
3. Exposure to UV exposure
Sun exposure accounts for 70 percent of skin cancer and is the biggest risk factor. Squamous cell carcinoma is the type most closely related to solar exposure. Exposure to ultraviolet light varies depending on the intensity of light, exposure time, and whether the skin is protected by clothing or sunscreen.
Skin cancer symptoms and types
There are certain characteristics that can indicate general and uncommon signs of skin cancer, melanoma. New spots on the skin could potentially be skin cancer. Given that one in five people will develop at least one skin cancer in their lifetime, a biopsy or a thorough examination is required to make sure they are different from other types of skin cancer, but the general shape of these tumors is also somewhat different, so be aware.
1. Basal cell carcinoma
It may be flat, raised, or dome-shaped, and may be pink, pale, or flesh-colored. Careful examination may show small blood vessels compared to surrounding skin. As a characteristic of basal cell cancer, ulcers occur very often, and it is also called rodent ulcers because mice appear to nibble at them.
2. Squamous cell carcinoma
It feels stiff when you touch it because it's raised. It can be scaly and can cause ulcers. That is, there is a central depression that is lighter and flat than the peripheral area. This cancer sometimes bleeds or forms scabs.
3. melanoma
In general, it appears as a change in existing points or a change in new and abnormal points.
4. All types of frequent symptoms
The following are early symptoms of skin cancer that can be common to all types.
an incurable wound
Many skin cancers are initially ignored as a result of insect bites, minor injuries, or irritation, but become more apparent when they do not disappear over time. If you have an ulcer in your skin that does not heal, or if it appears to heal but reappears, you should see a doctor.In general, if it is not treated on its own for two weeks, skin changes should be carefully monitored.
Changes in existing skin lesions
Some skin cancers are caused by long-standing skin lesions or spots. If freckles, spots, or other skin spots change, hospital treatment is recommended.
the sensation of skin lesions
In most cases, there is no sensation associated with spots or other skin lesions. Skin cancer can cause persistent itching, tenderness, numbness, tingling, or pain. Some people describe the sensation as a feeling similar to an ant crawling over the skin.
5. Uncommon symptoms
Other symptoms of skin cancer may also appear. The following are symptoms that are uncommon but can occur occasionally.
a change in the eye
Vision changes, such as blurred vision in one eye, can be ocular melanoma. It accounts for about 5% of all cases of melanoma occurring in the eye and occurs in the iris, shapeless body, or choroid membrane. Other symptoms include black spots on the whites of the eyes, loss of vision around them, flashing lights, or floating objects.
a thick line of nails or toenails
It should always be carefully observed that dark areas under nails or toenails appear without any particular damage. Melanoma at the base of the fingernail appears, including colored stripes.
