The difference between melanoma and mole What symptoms will a mole have before it turns cancerous?

Both melanoma and moles are pigmented tumors. Moles are benign lesions and only require attention, while melanoma is a more malignant tumor. So what is the difference between melanoma and mole? What symptoms will a mole have before it turns cancerous?

Melanoma and moles are both pigmented tumors. Moles are benign lesions and only require attention, while melanoma is a more malignant tumor, so the two must be distinguished. Some characteristics of malignant melanoma are different from those of moles. First, it grows faster. From a morphological point of view, its boundaries are unclear and the surface pigmentation is uneven. When a mole bleeds, ulcers, or necrosis occurs, or there are small moles around the mole, such as satellite lesions, these conditions may indicate that the mole is not an ordinary pigmented mole and requires high vigilance.

What is the difference between melanoma and mole?

In medicine, we call it a nevus with pigmented nevus or nevus cells. This is the last benign tumor of the skin. Most people have 10 to 40 moles on their bodies.

Generally speaking, melanocytes are evenly distributed in the skin and are the main cells that produce melanin in the body. If due to congenital or acquired factors, melanocytes gather into clumps or proliferate, forming moles. At this time, the melanocytes are called nevus cells.

Due to congenital or acquired factors, nevus cells can transform into melanoma. Therefore, moles and melanoma can be said to be "from the same root".

Generally speaking, melanoma has a larger diameter, smoother edges, and is prone to serration. The color of melanoma is often mixed with other colors and can appear as a mixture of white and black. Common moles are usually smaller in diameter, appear more symmetrical, and have a single color. In addition, moles are generally flat and integrated with the surface of human skin, but melanomas are different. Most melanomas are raised and people can feel them when they touch them.

What symptoms will a mole have before it turns cancerous?

1. The growth pattern of normal moles is relatively consistent. If a mole starts to become uneven and jagged, you should be alert.

2. Variegated color is also a signal of abnormality. Melanoma is characterized by a freckled pattern, with superficial spreading patterns of brown or black with patches of red, white, and blue. Even more unlucky is blue.

3. The surrounding skin becomes swollen or loses its luster, turns white or gray.

4. The mole becomes rough and uneven, with scaly or flaky desquamation, and sometimes bleeds.

5. Local itching, burning pain, or pain upon pressing. As the mole continues to degenerate and develop into an ulcerative lesion, symptoms of exudation and bleeding will appear, and the stinging or burning sensation will become more obvious.

Melanoma is uncommon in Asian populations. However, exogenous stimulation such as laser mole removal will still increase the risk of its occurrence, so you should be more careful.
