Skin cancer is a serious disease that threatens the lives of many people around the world, so it is very important to recognize the symptoms, so that the condition does not escalate into a very serious matter.
Many people are unaware of what skin cancer can look like, and it not only causes moles to change, but can lead to the appearance of lumps and lesions that some may miscalculate their risks, according to healthline.
Spreading places
Skin cancer spreads to areas of skin exposed to the sun, including the scalp, face, lips, ears, neck, chest, arms, hands, and on the legs.
its types
Non-melanoma skin cancer:
Non-melanoma skin cancer refers to a group of cancers that develop slowly in the upper layers of the skin.
The cells in the epidermis (the top layer of the skin) are most at risk of sun damage.
In the epidermis, the most common cells are called keratinocytes, and these cells are constantly shed when new cells are formed, however, when the skin is exposed to a lot of sunlight, it causes DNA damage, and over time, this becomes a problem, and causes the cells to grow abnormally Controlled, which leads to carcinomas.
Melanoma skin cancer:
Melanoma or melanoma is a type of skin cancer that can spread to other parts of the body.
Melanocytes are cells in the skin that give us the color of our skin because they produce a pigment known as melanin. When exposed to the sun, melanocytes produce more pigment, which spreads to other skin cells to protect them from the sun’s rays.
But melanocytes are also the site of cancer staging, where too much UV rays cause sunburn, a sign of skin DNA damage.
Ultraviolet radiation causes changes in the melanocytes, making the genetic material defective and causing abnormal cell growth.
And people who burn easily are more likely to get skin cancer because their cells don’t produce as much pigment to protect their skin.
People with albinism are most at risk because their skin produces no pigment at all.
Symptoms
An open sore that does not heal or heal and comes back.
A hard lump on the skin that bleeds spontaneously.
A small pink, red, shiny, pearly, or translucent bump that may have black, blue, or brown areas.
A prominent red spot that causes itching.
A flat, firm area that looks like a pale or yellowish scar.
A hard lump on the skin that doubles in size within weeks.
treatment
Skin cancer can be treated when caught early, however, there is a chance it will come back.
Types of treatment depend on the type of skin cancer, its extent, location and stage.
The main treatment is surgery to remove it from the affected area. The surgery is usually simple and performed under local anesthesia.
When surgery can’t be used, other treatments include radiation therapy, immunotherapy and chemotherapy cream.
