What is melanoma? What are the common types of melanoma?

If irregular black spots suddenly appear on a person's lips, it should be noted that this may be melanoma, just like the spots on the labia should also be noted. Because these parts are common sites for melanoma. Generally, melanoma is caused by a cancer cell, a tumor cell disease at the junction of the mucosa and the skin, which is also one of the common types of tumors.

Due to the emergence of various pollutions in life, viruses have also appeared and produced various forms, just like melanoma. There are more and more patients, so we must understand it in time to discover it earlier. To understand what melanoma is, we need to look at the location of the disease, the manifestation of the disease, the clinical classification, etc. Let's take a look at what melanoma is.

Melanoma generally refers to:

1. The location of the disease is quite special

This type of melanoma can be accurately distinguished because its location has obvious characteristics. It tends to occur on the patient's skin, and not just on the skin, but where the skin and mucous membrane meet, like next to our lips, where the lips meet the skin, and where the labia are, because the labia is also the junction of the mucous membrane and the skin. Occasionally, there are patients whose disease occurs on the eyes and in the brain, but such patients are still extremely rare.

2. Symptoms of the disease

The manifestation of this melanoma is that the skin color of the patient's diseased area will be obviously different, often with one black patch and another yellow patch. Moreover, the shape of the diseased area is very irregular. It is neither a clear circle nor a clear triangle. It often has one piece that is extra and one piece that is retracted. There is no accurate shape of the disease. The area of ​​this disease is generally about eight millimeters in diameter, or even larger, and they are all asymmetrical and uneven black patches.

3. Clinically, there are four common types of melanoma

To understand what a disease is, we need to know its normal types, so we also need to know the types of this disease. There are freckles on the hands and feet, malignant freckles, nodules, and types that only spread in the superficial layer of the patient's skin. All of these are melanoma conditions, and patients should pay close attention.
