skin cancer signs and symptoms: A change in the skin is the most common sign of skin cancer. These changes may be a new skin lesion, a sore that does not heal, or a change in a mole. Not all skin cancers look the same.

What are the skin cancer signs and symptoms ?

Skin cancer is the most common form of the disease, but it is generally one of the most curable types of cancer.

According to the American Cancer Society, more than 3.5 million cases of skin cancer are diagnosed each year in the United States. This is more than all other cancers combined.

In recent decades, the number of cases of skin cancer has been increasing.

Almost all types of this cancer result from excessive exposure to ultraviolet light, although a certain amount may come from man-made sources, such as tanning beds.

The risk of developing melanoma, the most dangerous type of skin cancer, is double in people who get sunburned.

“People underestimate the damage that sunburn can do to their skin. Many people think that redness of the skin is just a harmless part of the skin tanning process, rather than a sign of irreparable damage,” he said. to the BBC Johnathon Major of the British Association of Dermatologists.

According to Walayat Hussain, a skin cancer specialist at the Leeds Teaching Hospitals NHS Trust, “an early diagnosis is the key to a cure.”

The melanoma alphabet

The best way to prevent melanoma is to pay attention to the skin and especially to the moles, according to experts

The ABCDE rule helps you understand the warning signs of melanoma.

A for asymmetry: a mole that, when divided in half, does not look the same on both sides.
B per edge: a mole with edges that are poorly defined or irregular.
C for Color – Changes in the color of a mole, including darkening, color spreading, fading, or the appearance of different colors, such as blue, red, white, pink, purple, or gray.
D by diameter: a mole larger than 1/4 inch in diameter (about the size of a pencil’s eraser).
E for elevation: a mole that is elevated above the skin and has an uneven surface.

Other warning skin cancer signs and symptoms are:

skin cancer signs and symptoms: A sore that does not heal. Spread of pigment from the edge of a stain to the surrounding skin. Redness or new inflammation beyond the edge. Change in sensation (itching, tenderness, or pain). Change in the surface of a mole (peeling, oozing, bleeding, or the appearance of a lump or lump).

Sometimes it is difficult to distinguish the difference between melanoma and an ordinary mole, so Hussain recommends that you show your doctor any mole that you suspect.
Caution

The British specialist also gave several tips to prevent skin cancer.

“It is a matter of being sensible about the sun,” he said.

Among them he highlighted:

  • Avoid sunbathing between eleven in the morning and three in the afternoon
  • Make sure you are wearing a hat and have sunscreen with a high protection rating applied
  • Apply the cream frequently
  • Avoid burning the skin at all costs

Symptoms of non-melanoma skin cancer

– Basal cell carcinoma: reddish plaques with or without peeling; persistent small ulcers; apparent scars that increase in size or appearance of pearly nodules. It is the least aggressive type, but can cause severe deformities and damage if not diagnosed early. It usually appears in the areas of the body most exposed to solar radiation, such as the center of the face, nose and eyelids.

– Squamous cell carcinoma: red and rough spots that can bleed and crust without being the result of a wound; ulcers that recur and do not heal; or nodules. If it is not detected in time, it can metastasize. It also appears more frequently in the areas of the body that are exposed to the sun. Although it can occur in other areas such as the oral mucosa, tongue, genitals and anus. In these latter cases, it is more aggressive.

“Nor should we forget about precancerous lesions, which will lead to non-melanoma skin cancer if they are not diagnosed and treated in time. The most common is actinic keratosis. The main symptoms are slight rough, reddish, pigmented or even white bumps on the skin (excrescences) that are itchy and burning and appear and disappear in the same area. The most common areas of appearance are: ears, head, face, lips, necks, hands and forearms ”adds Dr. Sánchez Viera.
