Why is there a line in this position of a girl's body?

This line may also be "melanin precipitation".Girls in their bodies will change during their development, pregnancy, and lactation.This hormone may mobilize melanocyte work to synthesize more melanin.However, don't worry too much about this situation. There is nothing after the recovery of hormones in the body.However, if this pigmentation has grown suddenly, it may be caused by endocrine disorders.

This line may also be caused by Mondor disease.The Chinese name of this disease is shallow thrombosis of the chest wall. There are several characteristics of this line: in most cases, only 2-3cm long. Tighten the skin and find it.I will find a little pain at a time.The age of onset is 20-40 years old, and women are about 2-4 times that of men.

Seeing this, is it faintly feeling that this is a very serious disease, but in fact, the disease is very weak, the cause is not clear, and most of them will disappear within 2-3 months.So even if you touch this line, you don't have to make a fuss.

One minute of Ph.D., the posture continues to rise
