What are the symptoms of melanoma? 5 daily causes that may easily induce melanoma

Melanoma is a highly malignant tumor, also known as malignant melanoma. Most of them originate from the skin, but can also originate from the eyes, nasal cavity, etc. Metastasis can occur in the early stage, and the most common sites of metastasis are the lungs and brain. Once diagnosed, extensive tumor resection should be performed as soon as possible, and comprehensive measures such as auxiliary immunotherapy should be taken. The incidence of malignant melanoma in my country is not high, but because doctors and patients do not have a good understanding of its severity, it is usually too late when they seek medical treatment, and the treatment effect is extremely unsatisfactory. So today we will introduce some basic knowledge about melanoma.

Causes of Melanoma

(1) Air pollution

The large-scale emission of harmful substances such as Freon has destroyed the ozone layer, resulting in insufficient ultraviolet filtration. Harmful ultraviolet rays and harmful substances in the air work together to act on human skin, causing abnormal expression of melanocytes and triggering melanoma.

(2) The desire for beauty

In pursuit of clean and tender skin, many people use a large amount of chemical cosmetics, causing chemical skin pollution. Some people even use chemical corrosives to remove moles on the skin, but the result is counterproductive and stimulates the excessive proliferation of melanocytes.

(3) Lack of health knowledge

Not enough attention has been paid to moles growing on areas prone to friction, such as the feet and perineum, which have been subjected to long-term compression and friction, eventually leading to malignant transformation.

(4) Abuse of estrogen drugs

Studies have found that there are estrogen receptors in the cells of malignant melanoma, so people suspect that excess estrogen can stimulate the occurrence of melanoma.

(5) Free from defects

With the improvement of living standards, the life expectancy of Chinese people has been significantly extended. With the increase of age, the immune function of the human body gradually declines. Studies have found that low immune function is one of the important causes of melanoma, so the incidence of melanoma in the elderly is very high clinically.

Symptoms of Melanoma

Different types of melanoma have different clinical manifestations, which can be used to distinguish the types of melanoma. The early manifestations of acral melanoma mainly occur on the palms, soles and subungual areas. The lesions in the radiation growth phase are brown, brown or black and do not protrude above the skin surface. If irregular brown or brown stripes can be seen under the nail, they extend from the nail bed to the proximal end. The radiation growth phase lasts for about 1 year. If not treated in time, it will enter the vertical growth phase. The melanoma lesions are nodular and the lymph node metastasis rate also increases.

Warm reflection: Melanoma is very malignant. Patients must pay attention to go to a regular hospital for examination and treatment in time when the early symptoms of melanoma appear. This can greatly reduce the threat of melanoma and cure melanoma as soon as possible. In addition, for a melanoma patient, daily life care is also essential, otherwise, melanoma may reappear.
